This page runs the ChatCLI server in a container and on Kubernetes with the server Helm chart. For operator-managed servers (Instance resources and the AIOps pipeline) see K8s Operator.

Every recipe below sets a credential. A server that listens beyond loopback (any container with a published port, every Kubernetes pod) refuses to start without a shared token, JWT material or a client CA, and by default says so only in its log file. See the credential rule.

  --certificate-identity-regexp 'https://github.com/diillson/chatcli/'

The server image contains /usr/local/bin/chatcli (stamped with the release version, which GetServerInfo and the operator report), ENTRYPOINT ["chatcli", "server"], EXPOSE 50051, and a HEALTHCHECK that runs chatcli healthcheck every 30 seconds. The check resolves the server’s port, bind and TLS the way the server does, from its CHATCLI_SERVER_* variables and its flags, so it follows them with no extra configuration. Arguments after the image name are chatcli server flags. The Devin CLI is not in the image, so DEVIN is not a server provider.

Build locally

# Server image (from the repository root)
docker build -t chatcli:dev --build-arg VERSION=dev .

# Operator image: also from the repository root (operator/go.mod replaces the root module with ../)
docker build -f operator/Dockerfile -t chatcli-operator:dev .

Without --build-arg VERSION=… the binary reports version dev.

Docker

The server binds 127.0.0.1 outside Kubernetes, which inside a container means nothing outside the container reaches it. Publishing a port therefore needs CHATCLI_BIND_ADDRESS=0.0.0.0, and that bind needs a credential.

export CHATCLI_SERVER_TOKEN="$(openssl rand -hex 32)"
export ANTHROPIC_API_KEY=sk-ant-xxx

docker run -d --name chatcli \
  -p 50051:50051 -p 9090:9090 \
  -e CHATCLI_BIND_ADDRESS=0.0.0.0 \
  -e CHATCLI_SERVER_TOKEN \
  -e LLM_PROVIDER=CLAUDEAI \
  -e ANTHROPIC_API_KEY \
  -v chatcli-home:/home/nonroot \
  ghcr.io/diillson/chatcli:1.226.0

Setting	Why
`CHATCLI_BIND_ADDRESS=0.0.0.0`	listen on the container interface so the published port works
`CHATCLI_SERVER_TOKEN`	the credential that bind requires (or `CHATCLI_JWT_SECRET` / `CHATCLI_JWT_PUBLIC_KEY`)
`-v chatcli-home:/home/nonroot`	keep `~/.chatcli` (sessions, conversation hub, memory, plugins, log file) across restarts; the image’s home is `/home/nonroot`, and a named volume there inherits its ownership
`-p 9090:9090`	optional: `/metrics` and `/healthz`

In a container the server writes its log to stderr as JSON lines, so docker logs carries startup errors and everything after them with no extra setting (CHATCLI_ENV=dev switches to the colored development console instead). Check it and connect (the listener is plaintext, so the client needs CHATCLI_ALLOW_INSECURE=true):

docker logs chatcli | grep listening          # 🚀 ChatCLI server listening on 0.0.0.0:50051
docker inspect --format '{{.State.Health.Status}}' chatcli   # healthy
curl -s localhost:9090/healthz                 # ok

CHATCLI_ALLOW_INSECURE=true chatcli connect localhost:50051 --token "$CHATCLI_SERVER_TOKEN"

For a quick test without a credential, keep the server on loopback inside the container and use it from there only: omit CHATCLI_BIND_ADDRESS and the -p flags.

TLS in Docker

# tls/ holds server.crt, server.key and ca.crt, readable by UID 65532
docker run -d --name chatcli -p 50051:50051 \
  -e CHATCLI_BIND_ADDRESS=0.0.0.0 -e CHATCLI_SERVER_TOKEN \
  -e LLM_PROVIDER=CLAUDEAI -e ANTHROPIC_API_KEY \
  -e CHATCLI_SERVER_TLS_CERT=/etc/chatcli/tls/server.crt \
  -e CHATCLI_SERVER_TLS_KEY=/etc/chatcli/tls/server.key \
  -v "$PWD/tls:/etc/chatcli/tls:ro" \
  -v chatcli-home:/home/nonroot \
  ghcr.io/diillson/chatcli:1.226.0

chatcli connect localhost:50051 --tls --ca-cert tls/ca.crt --token "$CHATCLI_SERVER_TOKEN"

The built-in HEALTHCHECK picks up TLS from the server’s settings and trusts exactly the certificate it serves, so the container turns healthy with no override. With mutual TLS (CHATCLI_SERVER_TLS_CLIENT_CA), also pass CHATCLI_TLS_CLIENT_CERT and CHATCLI_TLS_CLIENT_KEY, the client pair chatcli connect uses, issued by that CA. The server certificate needs localhost in its SANs for the client above; see TLS for a certificate recipe.

Docker Compose

The repository’s docker-compose.yml builds the image from source and runs it hardened (read-only root filesystem, no-new-privileges, a 100 MB /tmp tmpfs, 2 CPUs / 1 GB). It binds 0.0.0.0 and reads every provider variable from your shell, so export a credential first:

git clone https://github.com/diillson/chatcli.git && cd chatcli
export CHATCLI_SERVER_TOKEN="$(openssl rand -hex 32)"
export LLM_PROVIDER=CLAUDEAI ANTHROPIC_API_KEY=sk-ant-xxx
docker compose up -d --build

CHATCLI_ALLOW_INSECURE=true chatcli connect localhost:50051 --token "$CHATCLI_SERVER_TOKEN"

The compose file sets HOME=/home/nonroot and keeps the whole home in one named volume, chatcli-home, mounted at /home/nonroot: ~/.chatcli (sessions, the conversation hub, memory, plugins, the log file) survives restarts, and the volume is writable under the read-only root filesystem because Docker seeds it with the ownership of the image’s home. Drop plugin binaries into ~/.chatcli/plugins inside that volume. The image’s HEALTHCHECK follows the server’s TLS settings on its own, so turning TLS on in Compose needs no health check override. CHATCLI_FALLBACK_PROVIDERS alone turns on the fallback chain (there is no separate enable switch), and it must list the primary provider first. The compose file also passes CHATCLI_FALLBACK_MAX_RETRIES (default 2), CHATCLI_FALLBACK_COOLDOWN_BASE (30s) and CHATCLI_FALLBACK_COOLDOWN_MAX (5m) from your shell.

Kubernetes (Helm)

The server chart is published as an OCI artifact at oci://ghcr.io/diillson/charts/chatcli. Chart version and server image version are the same number, and the chart’s appVersion pins the image.

Prerequisites

Kubernetes 1.30+, kubectl pointed at the cluster
Helm 3.8+ (OCI support), Helm 4 included
An LLM provider key (or IRSA / Workload Identity for Bedrock)

Install

Install with a credential

helm install chatcli oci://ghcr.io/diillson/charts/chatcli \
  --version 1.226.0 \
  --namespace chatcli --create-namespace \
  --set llm.provider=CLAUDEAI \
  --set secrets.anthropicApiKey="$ANTHROPIC_API_KEY" \
  --set server.token="$(openssl rand -hex 32)"

Inside a pod the server binds 0.0.0.0, so server.token (or JWT / mTLS, below) is required. The chart stores the token in its Secret and delivers it as CHATCLI_SERVER_TOKEN through secretKeyRef, never as a command-line argument. In a pod the server also writes its log to stderr, so kubectl logs shows it.

Wait for it

kubectl -n chatcli rollout status deploy/chatcli
kubectl -n chatcli logs deploy/chatcli | grep listening
# 🚀 ChatCLI server listening on 0.0.0.0:50051

Connect

export CHATCLI_REMOTE_TOKEN="$(kubectl -n chatcli get secret chatcli \
  -o jsonpath='{.data.CHATCLI_SERVER_TOKEN}' | base64 -d)"

kubectl -n chatcli port-forward svc/chatcli 50051:50051 &
CHATCLI_ALLOW_INSECURE=true chatcli connect localhost:50051 --token "$CHATCLI_REMOTE_TOKEN"

Object names follow the release: a release named other than chatcli produces <release>-chatcli (Deployment, Service and Secret). helm install prints the exact commands in its notes, and warns when no credential is set.

What the chart creates: a Deployment (non-root UID 1000, read-only root filesystem, all capabilities dropped, RuntimeDefault seccomp), a Service, a ConfigMap and a Secret loaded with envFrom, a ServiceAccount and RBAC for the watcher, a 1 Gi PVC for sessions (persistence.enabled, default on), the 17 AIOps CRDs plus a pre-install/pre-upgrade hook that re-applies them (crdUpgrade.enabled), and optionally an Ingress, HPA, PDB, NetworkPolicy and ServiceMonitor.

Probes

A kubelet grpc probe cannot do TLS, so the chart probes:

Probe	Check	Timing
startup	`GET /healthz` on the `metrics` port	every 5 s, up to 30 failures
liveness	`GET /healthz` on the `metrics` port	every 20 s, 3 failures
readiness	TCP connect to the `grpc` port	every 10 s, 3 failures

With server.metricsPort: 0 startup and liveness fall back to a TCP check on the gRPC port. These probes work with and without TLS.

Credentials

Option	Values	Notes
Shared token	`server.token`, or `CHATCLI_SERVER_TOKEN` in `secrets.existingSecret`	role `admin` for every caller
HS256 JWTs	`security.jwtSecretRef: {name, key}` (or inline `security.jwtSecret`)	tokens need `exp`; see JWT
RS256 JWTs	`security.jwtPublicKeyRef: {name, key}` (or inline `security.jwtPublicKey`)	several PEM keys may be listed, for rotation
Mutual TLS	`tls.*` plus `security.tlsClientCA` (a path in the pod)	every connection needs a client certificate
None	`security.bindAddress: "127.0.0.1"`	reachable only from inside the pod

security.jwtIssuer / security.jwtAudience add iss / aud checks; security.mtlsRole sets the role of certificate-only callers (viewer/readonly, user/operator, admin; default user). Prefer the *Ref values: inline ones land in the Deployment’s environment.

kubectl -n chatcli create secret generic chatcli-jwt --from-literal=secret="$(openssl rand -hex 32)"
helm upgrade chatcli oci://ghcr.io/diillson/charts/chatcli --version 1.226.0 -n chatcli \
  --reset-then-reuse-values --set security.jwtSecretRef.name=chatcli-jwt --set security.jwtSecretRef.key=secret

TLS

# values-tls.yaml
tls:
  enabled: true
  existingSecret: chatcli-tls              # kubernetes.io/tls Secret, mounted at /etc/chatcli/tls

With tls.existingSecret, certFile and keyFile default to /etc/chatcli/tls/tls.crt and /etc/chatcli/tls/tls.key; set them only when the files in your Secret have other names. Without a Secret, set both paths (to files you mount with extraVolumes / extraVolumeMounts).

tls.enabled: true with neither tls.existingSecret nor both certFile and keyFile fails helm install / helm upgrade (tls.enabled=true needs tls.existingSecret ... or both tls.certFile and tls.keyFile), instead of starting a server that would listen in plaintext.

For mTLS with a client CA that lives in the same Secret use security.tlsClientCA: /etc/chatcli/tls/ca.crt; for a separate CA Secret mount it with extraVolumes / extraVolumeMounts (example in Security values). Through kubectl port-forward the certificate needs localhost in its SANs.

Values reference

Server

Value	Default	Description
`replicaCount`	`1`	Replicas (ignored when `autoscaling.enabled`)
`strategy`	`{}`	Deployment update strategy, rendered as written; empty = chosen from persistence (see Rollouts on the sessions volume)
`image.repository` / `image.tag` / `image.pullPolicy`	`ghcr.io/diillson/chatcli` / chart `appVersion` / `IfNotPresent`	Server image
`imagePullSecrets`	`[]`	Pull secrets
`server.port`	`50051`	gRPC port
`server.metricsPort`	`9090`	`/metrics` and `/healthz`; `0` disables both

`server.token`	`""`	Shared token (required unless JWT or mTLS)
`server.grpcReflection`	`false`	Sets `CHATCLI_GRPC_REFLECTION=true`, which registers gRPC server reflection; reflection calls still need the server credential. Keep it off in production
`extraEnv`	`[]`	Extra environment variables (for example `LOG_LEVEL=debug`); an entry for a `CHATCLI_LOG_*` variable replaces the chart’s `logging` value
`logging.maxSizeMB` / `maxBackups` / `maxAgeDays` / `compress`	`20` / `3` / `28` / `true`	Log file rotation → `CHATCLI_LOG_MAX_SIZE_MB`, `CHATCLI_LOG_MAX_BACKUPS`, `CHATCLI_LOG_MAX_AGE_DAYS`, `CHATCLI_LOG_COMPRESS` (see Logs, health and metrics)
`extraVolumes` / `extraVolumeMounts`	`[]`	Extra volumes for the server container

LLM

Value	Default	Description
`llm.provider`	`""` (first provider with credentials)	`OPENAI`, `OPENAI_ASSISTANT`, `CLAUDEAI`, `BEDROCK`, `GOOGLEAI`, `XAI`, `ZAI`, `MINIMAX`, `MOONSHOT`, `STACKSPOT`, `OLLAMA`, `COPILOT`, `OPENROUTER`, or a provider plugin name
`llm.model`	`""`	Default model
`secrets.existingSecret`	`""`	Your Secret, loaded with `envFrom` (keys are variable names) instead of the chart’s
`secrets.openaiApiKey`, `anthropicApiKey`, `googleaiApiKey`, `xaiApiKey`, `zaiApiKey`, `minimaxApiKey`, `moonshotApiKey`, `openrouterApiKey`, `githubCopilotToken`	`""`	Provider keys → `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GOOGLEAI_API_KEY`, `XAI_API_KEY`, `ZAI_API_KEY`, `MINIMAX_API_KEY`, `MOONSHOT_API_KEY`, `OPENROUTER_API_KEY`, `GITHUB_COPILOT_TOKEN`
`secrets.minimaxApiCompat`	`""`	`anthropic` = Anthropic Messages API compatibility
`secrets.stackspotClientId`, `stackspotClientKey`, `stackspotRealm`, `stackspotAgentId`	`""`	StackSpot (`CLIENT_ID`, `CLIENT_KEY`, `STACKSPOT_REALM`, `STACKSPOT_AGENT_ID`)
`secrets.awsAccessKeyId`, `awsSecretAccessKey`, `awsSessionToken`, `bedrockRegion`, `awsRegion`	`""`	Bedrock; leave the keys empty for IRSA (`serviceAccount.annotations`)
`secrets.chatcliBedrockCaBundle`, `chatcliBedrockInsecureSkipVerify`	`""`	Bedrock CA bundle path / skip verification (troubleshooting only)
`copilot.model`, `copilot.maxTokens`, `copilot.apiBaseUrl`	`""`	`COPILOT_MODEL`, `COPILOT_MAX_TOKENS`, `COPILOT_API_BASE_URL`
`ollama.enabled`, `ollama.baseUrl`, `ollama.model`	`false`, `http://ollama:11434`, `""`	Server-side Ollama (not subject to the SSRF check)

With secrets.existingSecret, create the Secret with variable names as keys, the credential included:

kubectl -n chatcli create secret generic chatcli-llm-keys \
  --from-literal=CHATCLI_SERVER_TOKEN="$(openssl rand -hex 32)" \
  --from-literal=ANTHROPIC_API_KEY="$ANTHROPIC_API_KEY"
helm install chatcli oci://ghcr.io/diillson/charts/chatcli --version 1.226.0 -n chatcli \
  --set llm.provider=CLAUDEAI --set secrets.existingSecret=chatcli-llm-keys

Provider fallback

Value	Default	Description
`fallback.enabled`	`false`	Turn the chain on
`fallback.providers`	`[]`	Providers after `llm.provider`, each `{name, model}`; without `model` a provider runs its own default model
`fallback.maxRetries`	`2`	Attempts per provider; `0` fails over at once
`fallback.cooldownBase` / `fallback.cooldownMax`	`30s` / `5m`	Cooldown after a failure / ceiling

The chart puts llm.provider (with llm.model) first unless you list it yourself, because the server builds the chain from the list alone and installs it only with two or more working providers. Put every provider’s key in the Secret. fallback.enabled only decides whether the chart writes CHATCLI_FALLBACK_PROVIDERS; the chart writes no separate enable variable, since the server reads none.

llm:
  provider: CLAUDEAI
  model: claude-sonnet-5
fallback:
  enabled: true
  providers:                    # effective chain: CLAUDEAI -> OPENAI -> GOOGLEAI
    - name: OPENAI
      model: gpt-6-sol
    - name: GOOGLEAI
      model: gemini-3.8-flash

MCP

Value	Default	Description
`mcp.enabled`	`false`	Turn MCP on
`mcp.servers`	`[]`	Inline servers: `name`, `transport` (`stdio`/`sse`), `command`, `args`, `url`, `env`, `enabled`, `overrides`
`mcp.existingConfigMap`	`""`	Your ConfigMap with a `mcp_servers.json` key, mounted at `/etc/chatcli/mcp` (wins over `servers`)

K8s watcher

Value	Default	Description
`watcher.enabled`	`false`	Turn the watcher on
`watcher.targets`	`[]`	Multi-target list of `{deployment, kind, namespace, metricsPort, metricsPath, metricsFilter}`; `deployment` is the resource name and `kind` is `Deployment` (default), `StatefulSet`, `DaemonSet`, `Job` or `CronJob`
`watcher.deployment` / `watcher.namespace`	`""`	Single-target mode (used when `targets` is empty), watches a Deployment; an empty namespace means the namespace named `default`
`watcher.interval` / `watcher.window`	`30s` / `2h`	Collection interval / retention
`watcher.maxLogLines` / `watcher.maxContextChars`	`100` / `32000`	Log lines per pod / LLM context budget

A target without kind is a Deployment; a target with a namespace omitted watches default. Targets outside the release namespace, or in several namespaces, switch the chart’s RBAC to a ClusterRole automatically, and so does a single-target watcher.namespace other than the release namespace (an empty one counts as default).

watcher:
  enabled: true
  interval: "15s"
  targets:
    - deployment: api-gateway
      namespace: production
      metricsPort: 9090
      metricsFilter: ["http_requests_*", "http_request_duration_*"]
    - deployment: postgres
      kind: StatefulSet
      namespace: production
    - deployment: nightly-report
      kind: CronJob
      namespace: batch

Storage, memory, pipeline and resources

Value	Default	Description
`persistence.enabled`	`true`	PVC `<fullname>-sessions` for sessions, mounted at `~/.chatcli/sessions`
`persistence.storageClass` / `accessModes` / `size`	`""` / `[ReadWriteOnce]` / `1Gi`	`-` = `storageClassName: ""`. Without `ReadWriteMany` a rollout stops the old pod first; `ReadWriteOncePod` fails the render with more than one replica
`memory.enabled`	`false`	Long-term memory at `~/.chatcli/memory` (on the sessions PVC when persistence is on, a 200Mi emptyDir otherwise)
`memory.subPath`	`memory`	Directory of the sessions PVC that holds memory when persistence is on; memory written at the PVC root by earlier charts is copied into it once. `""` = the PVC root, shared with the session files (the old layout)
`memory.vault.enabled`	`true`	Keep the Obsidian vault of the memory graph in sync (`CHATCLI_MEMORY_VAULT`). Plaintext even with encryption at rest; sensitive profile fields and secrets are masked
`memory.vault.dir`	`""`	Vault directory (`CHATCLI_MEMORY_VAULT_DIR`). Empty = `~/.chatcli/vault`, which is not on the sessions PVC, so the vault is rebuilt on every start; point it at a persistent volume (`extraVolumes`) to keep it
`pipeline.enabled`	`false`	Pipeline RPCs (`CHATCLI_SERVER_PIPELINE`)
`agents.`, `skills.`, `bootstrap.*`	disabled	`enabled`, `definitions` (inline files), `existingConfigMap`; enabled with neither, nothing is mounted
`skillRegistry.enabled`, `registryUrls`, `registryDisable`, `installDir`	`false`, `""`	Skill registry settings
`plugins.enabled`, `initImage`, `existingPVC`	`false`, `""`	Plugins directory, filled from an init image or a PVC; the init image’s `/providers/*` fills the provider plugins directory
`plugins.trustedKeysConfigMap`	`""`	ConfigMap of publisher public keys mounted at `/etc/chatcli/trusted-keys`, so signed plugins verify
`resources`	requests `100m`/`128Mi`, limits `500m`/`512Mi`	Container resources
`podSecurityContext` / `securityContext`	UID/GID/fsGroup 1000, non-root, `RuntimeDefault`; no privilege escalation, read-only root, drop `ALL`	Pod and container security
`nodeSelector`, `tolerations`, `affinity`	empty	Scheduling

The chart mounts an emptyDir at /home/chatcli/.chatcli and /tmp and sets HOME=/home/chatcli, so the read-only root filesystem works. The server reads the MCP, agents, skills and bootstrap ConfigMaps only at startup. Each one the chart renders (from mcp.servers or *.definitions) is hashed into a checksum/<name> pod annotation, so a helm upgrade that edits it rolls the pods. A ConfigMap you manage yourself (*.existingConfigMap) cannot be hashed by Helm: after editing one, run kubectl -n chatcli rollout restart deploy/chatcli. agents, skills or bootstrap enabled with neither definitions nor existingConfigMap mount nothing, and the server finds an empty directory (earlier charts mounted a ConfigMap that did not exist, leaving the pod in ContainerCreating).

Rollouts on the sessions volume

With persistence.enabled and no ReadWriteMany access mode, a rollout stops the old pod before starting the new one: the chart renders RollingUpdate with maxSurge: 0 and maxUnavailable: 1. Under the API server default (one surge pod, no unavailable pod), a new pod scheduled on another node could not attach the ReadWriteOnce volume while the old pod held it, and the old pod was only stopped once the new one was ready, so the rollout hung. Stopping the old pod first means a short gap in service on each rollout instead. Without persistence, or with ReadWriteMany, nothing is rendered and the API server default applies. An explicit strategy wins in every case; type: Recreate without rollingUpdate is rendered with rollingUpdate: null. A fresh install, a Helm 3 release, and a release already upgraded once on the chart’s default can switch to Recreate directly. A release installed by Helm 4 on an earlier chart (up to 1.211.x, which rendered no strategy) needs one upgrade on the default first, because Helm 4’s server-side apply cannot remove the defaulted rollingUpdate block (the upgrade fails with spec.strategy.rollingUpdate: Forbidden), or this patch:

kubectl -n chatcli patch deploy/chatcli --type=json \
  -p '[{"op":"remove","path":"/spec/strategy/rollingUpdate"},{"op":"replace","path":"/spec/strategy/type","value":"Recreate"}]'

strategy:
  type: Recreate

A ReadWriteOnce volume attaches to one node at a time, so several replicas on it work only while they all run on that node; pods scheduled elsewhere stay in ContainerCreating. Run one replica, or use a ReadWriteMany storage class for several. ReadWriteOncePod admits a single pod: the render fails when replicaCount (or autoscaling.maxReplicas with the HPA on) is above 1.

Memory on the sessions PVC

With memory.enabled and persistence, the sessions stay at the PVC root (mounted at ~/.chatcli/sessions) and memory lives in the memory.subPath directory of the same PVC (mounted at ~/.chatcli/memory). kubelet creates that directory on the first mount, and the default podSecurityContext.fsGroup makes it writable. Earlier charts (up to 1.211.x) mounted memory at the PVC root too, so its JSON stores sat among the session files, where the session list showed them and session expiry could delete them. Upgrading an install that ran with memory and persistence migrates on its own. No session moves. The chart sets CHATCLI_MEMORY_LEGACY_DIR=/home/chatcli/.chatcli/sessions (the PVC root as the server sees it) whenever persistence, memory and a memory.subPath are all on, and the first time the server opens memory on the new layout it copies memory’s own files from there into the memory directory:

only memory’s files (MEMORY.md and its backups, memory_index.json, memory_tombstones.json, episodes.json, user_profile.json, topics.json, projects.json, links.json, usage_stats.json, graph.json, vector_index.json, memory_archive.json, compactor_state.json, their .corrupt quarantines, the YYYYMM/ daily notes, weekly/, monthly/ and pending/); the session files stay where they are;
a copy only: nothing at the root is moved, deleted or rewritten, and a file already in the memory directory is never overwritten; each file lands atomically with mode 0600;
once: it runs only while the memory directory holds none of memory’s files, and writes the marker .migrated-from-legacy there when done;
an unreadable file is skipped with a warning; a file sealed with CHATCLI_ENCRYPTION_KEY is resealed for its new path, and while the key is missing or wrong the copy stays pending (.migrating-from-legacy) and resumes on the next start;
the log records it as memory: adopted the legacy memory directory.

memory.subPath: "" keeps the old shared layout instead (no copy, no CHATCLI_MEMORY_LEGACY_DIR). An upgrade with plain --reuse-values carries no memory.subPath key and keeps the old layout too; --reset-then-reuse-values picks up the new default.

`ingress.enabled`, `className`, `annotations`, `hosts`, `tls`	disabled	Ingress; `className: nginx` adds `backend-protocol: GRPC` and `ssl-redirect: "true"`, and the same keys in `annotations` replace those defaults
`networkPolicy.enabled`	`false`	Ingress to the gRPC and metrics ports
`networkPolicy.ingressFrom`	unset (any source)	Allowed peers
`networkPolicy.egress`	`allowAll`	`restricted` = DNS, 443, `kubernetesApiPort` (6443), `egressExtraPorts`

Scaling and monitoring

Value	Default	Description
`autoscaling.enabled`, `minReplicas`, `maxReplicas`, `targetCPUUtilizationPercentage`, `targetMemoryUtilizationPercentage`	`false`, `1`, `5`, `80`, unset	HPA
`podDisruptionBudget.enabled`, `minAvailable`, `maxUnavailable`	`false`, `1`, unset	PDB, rendered only when `replicaCount > 1`
`serviceMonitor.enabled`, `interval`, `scrapeTimeout`, `labels`	`false`, `30s`	Prometheus Operator ServiceMonitor on the metrics port
`serviceAccount.create`, `name`, `annotations`	`true`	IRSA / Workload Identity annotations go here
`rbac.create`, `clusterWide`, `additionalRules`	`true`, `false`, `[]`	Watcher and remediation RBAC. It grants no access to Secrets (the server never reads one through the API); add a rule scoped with `resourceNames` in `additionalRules` only for a plugin that needs one
`crdUpgrade.enabled`	`true`	CRD re-apply hook (kubectl image `registry.k8s.io/kubectl:v1.31.10`)
`prometheusUrl`	`""`	Deprecated, ignored by the server (set it on the operator chart)

The values schema rejects unknown keys, so a misspelled value fails the install instead of being ignored.

Exposing the server

Way	How	Client
Port-forward (development)	`kubectl -n chatcli port-forward svc/chatcli 50051:50051`	`CHATCLI_ALLOW_INSECURE=true chatcli connect localhost:50051 --token …` (or `--tls --ca-cert` with TLS)
Ingress, TLS at the ingress	`ingress.className: nginx`, `ingress.tls`, server plaintext	`chatcli connect chatcli.example.com:443 --tls --token …`
LoadBalancer / NodePort	`service.type`, with `tls.*` on	`chatcli connect <address>:50051 --tls --ca-cert ca.crt --token …`

# values-ingress.yaml: TLS terminates at ingress-nginx, gRPC to the pod
ingress:
  enabled: true
  className: nginx
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
  hosts:
    - host: chatcli.example.com
      paths:
        - path: /
          pathType: ImplementationSpecific
  tls:
    - secretName: chatcli-ingress-tls
      hosts: [chatcli.example.com]

With className: nginx the chart sets backend-protocol: GRPC (plaintext to the pod) and ssl-redirect: "true" as defaults. A key you set in ingress.annotations replaces the default instead of being rendered twice, so for end-to-end TLS through nginx (with tls.* on the server) add nginx.ingress.kubernetes.io/backend-protocol: GRPCS.

Logs, health and metrics

kubectl -n chatcli logs deploy/chatcli -f            # the banner, then the log as JSON lines
kubectl -n chatcli port-forward deploy/chatcli 9090:9090 &
curl -s localhost:9090/healthz                       # ok
curl -s localhost:9090/metrics | grep '^chatcli_server_info'

In a pod the server writes every log entry to stderr as JSON lines, which is what kubectl logs and your log collector read; the rotating file at /home/chatcli/.chatcli/app.log (an emptyDir, no shell to read it with) is a copy that dies with the pod. CHATCLI_LOG_STDERR=false in extraEnv turns the stderr copy off. With the default read-only root filesystem, /home/chatcli/.chatcli is an emptyDir limited to 200Mi, and a volume past its limit gets the pod evicted. The server’s own rotation defaults (100 MB, 3 backups: up to 400 MB) do not fit, so the chart sets a rotation that does, at most 80 MB of log:

Value	Default	Variable
`logging.maxSizeMB`	`20`	`CHATCLI_LOG_MAX_SIZE_MB`: size at which the file rotates
`logging.maxBackups`	`3`	`CHATCLI_LOG_MAX_BACKUPS`: rotated files kept
`logging.maxAgeDays`	`28`	`CHATCLI_LOG_MAX_AGE_DAYS`: days a rotated file is kept
`logging.compress`	`true`	`CHATCLI_LOG_COMPRESS`: gzip rotated files

While that emptyDir is in use, the render fails when maxSizeMB × (maxBackups + 1) exceeds 100 MB. A field set to null renders no variable (the server default applies and counts as such in the check). An extraEnv entry of the same name wins over the chart’s value, and one for the size or the backups skips the check.

logging:
  maxSizeMB: 10
  maxBackups: 5
extraEnv:
  - name: LOG_LEVEL              # debug | info | warn | error
    value: info
``` The metrics port has no authentication; restrict it with `networkPolicy.ingressFrom` where that matters.

### Upgrade, rollback, uninstall

```bash
helm upgrade chatcli oci://ghcr.io/diillson/charts/chatcli --version 1.226.0 \
  -n chatcli --reset-then-reuse-values
helm history chatcli -n chatcli
helm rollback chatcli <revision> -n chatcli
helm uninstall chatcli -n chatcli

A changed chart-managed Secret or ConfigMap rolls the pods (checksum annotations), the MCP, agents, skills and bootstrap ConfigMaps included. A changed secrets.existingSecret or *.existingConfigMap does not: run kubectl -n chatcli rollout restart deploy/chatcli.
With persistence on a volume without ReadWriteMany, each rollout stops the old pod before the new one starts: expect a short gap (see Rollouts on the sessions volume).
If both the server chart and the chatcli-operator chart are installed, keep them on the same version: each re-applies its own copy of the CRDs.
helm uninstall deletes the sessions PVC; back it up first. CRDs stay; deleting them deletes every resource of those kinds.

Troubleshooting

Symptom	Cause	Fix
Pod `CrashLoopBackOff`; `kubectl logs --previous` ends with `refusing to serve an unauthenticated API on 0.0.0.0`	No credential on a reachable bind	Set `server.token` or JWT
`helm install` notes print `WARNING: no credential is configured`	No token, JWT or client CA in the values	Set `server.token` or `security.jwtSecretRef`
Client: `tls: first record does not look like a TLS handshake`	Plaintext server (`tls.enabled=false`)	`CHATCLI_ALLOW_INSECURE=true`, or enable TLS
`helm install` fails with `tls.enabled=true needs tls.existingSecret`	TLS on without certificate material	Set `tls.existingSecret`, or both `tls.certFile` and `tls.keyFile`
Client: `x509: certificate is valid for …, not localhost`	Port-forward dials `localhost`	Add `localhost`/`127.0.0.1` SANs, or connect by the certificate’s name
`Error: values don't meet the specifications of the schema(s)`	Unknown or misspelled value	Check the key against the tables above
Watcher reports nothing for a namespace	RBAC: the chart made a Role, the target is elsewhere	Set the target’s namespace in `watcher.targets` or `watcher.namespace` (auto ClusterRole), or `rbac.clusterWide: true`
Sessions lost on restart	`persistence.enabled: false`	Enable it
Rollout hangs; the new pod sits in `ContainerCreating` with `Multi-Attach error`	A chart that rendered no strategy (up to 1.211.x), or an explicit `strategy` that surges, on a `ReadWriteOnce` volume	Upgrade on the default `strategy` (stop-first), or scale to one replica on one node
Extra replicas stuck in `ContainerCreating`	Several replicas on a `ReadWriteOnce` sessions volume, scheduled on other nodes	One replica, or `persistence.accessModes: [ReadWriteMany]`
`helm install` fails with `ReadWriteOncePod admits a single pod`	`ReadWriteOncePod` with `replicaCount` or `autoscaling.maxReplicas` above 1	One replica, or `ReadWriteMany`
`helm install` fails with `logging.maxSizeMB x (logging.maxBackups + 1) = … MB`	Log rotation larger than 100 MB on the data emptyDir	Lower `logging.maxSizeMB` or `logging.maxBackups`
`helm install` fails with `security.jwtSecret and security.jwtSecretRef both set` (or `jwtPublicKey` and `jwtPublicKeyRef`)	Inline value and Secret reference both set	Keep only the reference
Edited `*.existingConfigMap` not picked up	The server reads it only at startup, and Helm cannot hash it	`kubectl -n chatcli rollout restart deploy/chatcli`
Two replicas, one gets all traffic	ClusterIP pins HTTP/2 connections	`service.headless: true`
