Problem

The cost-onprem chart currently uses 'latest' image tags, which creates several issues:
- Deployment unpredictability (different nodes may pull different versions)
- Inability to rollback to previous versions
- Difficulty in troubleshooting and debugging
- Breaks reproducible deployments
- oc-mirror challenges with undefined image versions

Solution

Replace all 'latest' image tags with specific semantic version tags to improve deployment reliability and enable proper image lifecycle management.

Acceptance Criteria

• [ ] Audit all image references in chart templates and values files
• [ ] Identify current 'latest' tags and their corresponding stable versions
• [ ] Define semantic versioning strategy for all chart images
• [ ] Update default values.yaml with specific version tags
• [ ] Update chart templates to use versioned images
• [ ] Create documentation for image versioning strategy
• [ ] Test deployment with new versioned tags
• [ ] Verify all components start successfully with pinned versions
• [ ] Update CI/CD pipelines to handle versioned images
• [ ] Create process for updating image versions

Affected Images

• Custom built images (to be identified during audit)
• Third-party images (PostgreSQL, Redis/Valkey, MinIO, etc.)
• Cost management service images

Definition of Done

• No 'latest' tags remain in chart templates or values files
• All images use specific semantic version tags
• Deployment reproducibility is ensured
• Documentation reflects new versioning approach
• CI/CD processes support versioned images
