OWNERS

A simplified version of Prow's OWNERS file is supported. When an OWNERS file is present at the root of the repository, it is used to authorize the /lgtm and /approve commands. See an example using an OWNERS file.

The reviewers role grants access to the /lgtm command and the approvers role grants access to the /approve command.

The approvers role does not grant the reviewers role, a user must be in both roles to use /lgtm and /approve.

The OWNERS file must be in YAML format. All entries are expected to be GitHub usernames; teams are not supported.

# List of usernames who may use /lgtm
reviewers:
  - user1
  - user2
  - user3

# List of usernames who may use /approve
approvers:
  - user1
  - user2
  - admin1
