GitLab integration

argo-compare can post the comparison output as a comment on a GitLab Merge Request. Configure it with environment variables:

ARGO_COMPARE_COMMENT_PROVIDER=gitlab \
ARGO_COMPARE_GITLAB_URL=https://gitlab.com \
ARGO_COMPARE_GITLAB_TOKEN=$GITLAB_TOKEN \
ARGO_COMPARE_GITLAB_PROJECT_ID=12345 \
ARGO_COMPARE_GITLAB_MR_IID=10 \
argo-compare branch <target-branch>

Equivalent CLI flags are available:

argo-compare branch <target-branch> \
  --comment-provider gitlab \
  --gitlab-url https://gitlab.com \
  --gitlab-token "$GITLAB_TOKEN" \
  --gitlab-project-id 12345 \
  --gitlab-merge-request-iid 10

GitLab CI auto-detection

When running inside GitLab CI, most settings are detected automatically:

• --comment-provider defaults to gitlab when GITLAB_CI and CI_MERGE_REQUEST_IID are present.
• --gitlab-url falls back to CI_SERVER_URL.
• --gitlab-project-id falls back to CI_PROJECT_ID.
• --gitlab-merge-request-iid falls back to CI_MERGE_REQUEST_IID.
• --gitlab-token falls back to CI_JOB_TOKEN if no explicit token is provided (ensure the token has the necessary scope to post notes).
