Images' tags
Images tags format is [VERSION]-[STABILITY_TAG] where:
[VERSION] is the version of an application (without patch version) running in a container, e.g.
wodby/nginx:1.31-x.x.x where Nginx version is 1.31 and
x.x.x is a stability tag. For some images we include both major and minor version like Ruby
2.5, for others we include only major like Valkey 7.
[STABILITY_TAG] is the version of an image that corresponds to a git tag of the image repository, e.g.
wodby/mariadb:10.2-3.3.8 has MariaDB 10.2 and stability tag
3.3.8. New stability tags include patch updates for applications and image's fixes/improvements (new env vars, orchestration actions fixes, etc). Stability tag changes described in the corresponding a git tag description. Stability tags follow semantic versioning.
We highly encourage to use images only with stability tags.
Maintenance
