0.25.0 Migration Guide

Changes

• The network plugin can now set an initial-network for all containers on creation. This is a replacement for specifying the --network flag via the docker-options plugin. Please see the network documentation for more information.
• The dokku run command now always removes the ephemeral container on exit. Users that need a persistent container should instead specify a console process type in their Procfile specifying an available shell (usually either bash or sh) and scale that container appropriately.

Deprecations

• In previous versions of Dokku, the only way to specify a custom Dockerfile was to use the docker-options plugin to set the --file flag for a docker build. As of 0.25.0, the builder-dockerfile:set command should be used instead, as outlined in the docs here. Usage of the old method should be migrated to the new method.
• The --rm and ``--rm-containerflags may be specified but no longer have any effect ondokku run`.
• The --detach flag is deprecated in favor of the run:detached command.
• The DOKKU_SCALE file is deprecated. Please see the process management documentation for more information on it's replacement with the formations key of the app.json file.
