Configure the GitLab chart with UBI-based images
GitLab offers Red Hat UBI
versions of its images, allowing you to replace standard images with UBI-based
images. These images use the same tag as standard images with -ubi extension.
The UBI-based images prior to GitLab 17.3 use the
-ubi8 extension.The GitLab chart uses third-party images that are not based on UBI. These images are mostly offer external services to GitLab, such as Redis, PostgreSQL, and so on. If you wish to deploy a GitLab instance that purely based on UBI you must disable the internal services, and use external deployments or services.
The services that must be disabled and provided externally are:
- PostgreSQL
- MinIO (Object Store)
- Redis
The services must be disabled are:
- CertManager (Let’s Encrypt integration)
- Prometheus
- GitLab Runner
Sample values
We provide an example for GitLab chart values in examples/ubi/values.yaml
which can help you to build a pure UBI GitLab deployment.
