WSO2 Micro Integrator — OpenChoreo Platform Resources

This directory contains the OpenChoreo platform resources for building and deploying WSO2 Micro Integrator projects from source. Apply these once per cluster before deploying any MI component.

Platform resources

File	Kind	Description
micro-integrator.yaml	ClusterComponentType	Defines the deployment/micro-integrator component type
micro-integrator-builder.yaml	ClusterWorkflow	Build pipeline: checkout → build → publish → generate workload
micro-integrator-build.yaml	ClusterWorkflowTemplate	Argo template: compiles the Maven project and packages the .car into wso2/wso2mi

Install

kubectl apply \
  -f micro-integrator-build.yaml \
  -f micro-integrator-builder.yaml \
  -f micro-integrator.yaml

How the build pipeline works

1. checkout-source — clones the Git repository at the specified branch/commit.
2. build-image — detects the MI version from project.runtime.version in pom.xml (defaults to 4.4.0), runs mvn clean install, copies the .car into wso2/wso2mi:<version> from Docker Hub.
3. publish-image — pushes the image to the in-cluster registry.
4. generate-workload — creates a Workload CR with the built image.

Supported MI versions

1.1.0 · 1.2.0 · 4.0.0 · 4.1.0 · 4.2.0 · 4.3.0 · 4.4.0 · 4.5.0

Source repository requirements

• A pom.xml at the appPath root.
• Maven build must produce at least one .car file.
• Optionally place libs/, dropins/, or deployment.toml alongside pom.xml to customise the MI installation.

Environment configuration

The deployment/micro-integrator component type exposes these per-environment settings:

Parameter	Default	Description
replicas	1	Number of pod replicas
resources.requests.cpu	500m	CPU request
resources.requests.memory	1Gi	Memory request
imagePullPolicy	IfNotPresent	Kubernetes image pull policy
mode	DEFAULT	DEFAULT runs as a long-lived server; TASK runs a single CAR and exits
carFile	""	CAR file passed to --car when mode=TASK
