If your dependency manager (Renovate, Dependabot, etc.) suggests the rudder-server tag 31082021.130106, ignore it: that is an old build artifact, not a real release, and pulling it would downgrade you years back. The maintainers recommend either rudderlabs/rudder-server:latest or, if you want stability without surprise breaking changes, a pinned release tag like rudder-server:1.32. Check the GitHub Releases section of rudderlabs/rudder-server for the current stable tag before pinning. This is a good general rule for this image: never trust a numeric-looking tag you do not recognize; the release tags are the ones documented in the releases page.
