Pre-built Docker images for CI
Description
We let people bring their own Docker images for CI, which is great, but we make users do all the work to make these complete enough to run their builds and tests. We should consider providing pre-built environments that cover the 90% case. We have a separate issue about a kitchen-sink image (gitlab-foss#21626 (moved)), but this issue is more about language-specific, efficient images.
Proposal
Create pre-built images for:
- Clojure
- Elixir
- Go (golang)
- Java
- Node.js
- PHP
- Python
- Ruby
Also consider images for common database services that might be optimized better, or more complete, than stock database images:
- MongoDB
- MySQL
- PostgreSQL
