0.22.0 Migration Guide

Deprecations

  • Calling logs:failed without either a <name> or the --all flag is deprecated.

Changes

  • Underscores are no longer valid characters in app names. Please rename applications before upgrading.
  • Process type names specified in Procfile may no longer use characters not valid in DNS Label Names (RFC 1123).
  • The minimum Docker version is now 17.05.0.
  • The common.GetDeployingAppImageName() function now returns an error as the second return argument instead of calling common.LogFail() internally.
  • Setting DOKKU_DISABLE_ANSI_PREFIX_REMOVAL is deprecated; Dokku 0.23.0 will avoid removing the remote: ansi prefix entirely. No warning will be added in this release.

Removals

The ps command has had a few removals as a result of a rewrite to Golang:

  • The ps:set-restart-policy command has been removed in favor the ps:set command.
  • The ps:restart-policy command has been removed in favor of the ps:report command.
  • The ps:rebuildall command has been removed in favor of calling the ps:rebuild with the --all flag instead of an app name.
  • The ps:restartall command has been removed in favor of calling the ps:restart with the --all flag instead of an app name.
  • The ps:stopall command has been removed in favor of calling the ps:stop with the --all flag instead of an app name.
  • The ps:startall command has been removed in favor of calling the ps:start with the --all flag instead of an app name.
  • The DOKKU_PROCFILE file is no longer located in the git directory for a given app on the server. It's location is currently not exposed.
  • The procfile-get-command plugin trigger no longer takes a procfile path as the final argument.
  • All ps functions have been removed. Please us a trigger as appropriate or file a PR to have a new trigger/wrapper function added.
