Image tags

Wodby images that package upstream software use [VERSION]-r[N] tags, for example wodby/mariadb:11.4-r0. 11.4 selects the MariaDB version line and r0 identifies the Wodby image revision. Revisions include application updates and image changes; review the image release notes before upgrading because the revision number does not indicate compatibility.

Major/minor tags share a revision counter per image repository. Full-version tags, such as 11.4.2-r0, start at r0 again for each exact upstream version. Matching Git tags identify the source commit for each published revision. Development variants retain their qualifier, for example 8.5-dev-r0.

Use the versioned image tags supplied in .env instead of floating tags such as latest. Previously published tags remain available. Wodby software such as Backup uses semantic product versions, and third-party images follow their own tag formats. See the image revision policy for details.

Maintenance

We regularly update images used in this stack and release them together, see releases page for full changelog and update instructions. Most of routine updates for images and this project performed by the bot via scripts located at wodby/images.
