Replace hardcoded image: ...:develop references with version variables

[djuarezgf]

Problem

Currently, some services define their Docker image using a hardcoded :develop tag, like:

image: samply/some-service:develop

This approach makes it harder to manage versions consistently across different environments.

Proposal

We propose replacing hardcoded image tags with environment-specific variables. These variables are already defined in files under the versions/ directory. For example:

versions/prod

FOCUS_TAG=main
BEAM_TAG=main
BLAZE_TAG=0.32
POSTGRES_TAG=15.13-alpine

Each environment (acceptance, prod, test) has its own file that defines the necessary variables.

Example change

Instead of:

image: docker.verbis.dkfz.de/cache/samply/teiler-dashboard:develop

Use:

image: docker.verbis.dkfz.de/cache/samply/teiler-dashboard:${TEILER_DASHBOARD_TAG}

Tasks

• Identify all image: ...:develop references across the project.
• Replace them with the appropriate variable substitution (e.g., ${TEILER_DASHBOARD_TAG}).
• Ensure that the correct environment-specific file from the versions/ folder is loaded during deployment or CI.
• Test the setup to ensure the substitutions work correctly in all environments.

Benefits

• Cleaner separation of code and environment-specific configuration
• Centralized version management
• Easier updates and rollbacks per environment
• Improved reproducibility and deployment stability
