0.20.0 Migration Guide

Removals

Command removals

The following commands were previously deprecated and were removed in this release.

  • apps: Use apps:list instead.
  • certs: Use certs:report instead.
  • certs:info: Use certs:report instead.
  • checks: Use checks:report instead.
  • docker-options: Use docker-options:report instead.
  • domains: Use domains:report instead.
  • plugin: Use plugin:list instead.
  • proxy: Use proxy:report instead.
  • trace: Use trace:on or trace:off instead.
  • ps: Use enter with a container ID instead to run ps auxww within a container.

The refactor of the proxy plugin removes the following functions from being sourced in plugins:

  • proxy#get_app_proxy_port_map()
  • proxy#list_app_proxy_ports()
  • proxy#filter_app_proxy_ports()
  • proxy#add_proxy_ports()
  • proxy#remove_proxy_ports()
  • proxy#set_proxy_ports()

The informal policy is to allow removal of functions within a functions file if they are not used in OSS plugins. Should you be affected by any such removals, please file an issue to expose the functionality via a plugin trigger.

Function renames

  • tar#tar_in_cmd was renamed to tar#cmd-tar-in. Users should avoid using cmd-* commands directly, and instead file an issue to have them exposed via a plugin trigger.
  • tar#tar_from_cmd was renamed to tar#cmd-tar-from. Users should avoid using cmd-* commands directly, and instead file an issue to have them exposed via a plugin trigger.

Remove support for Unsupported Operating Systems

Dokku will no longer distribute packages for Ubuntu versions that have reached either End of Life or End of Standard Support (for LTS releases). This currently includes the following releases:

  • Ubuntu 14.04 (trusty)
  • Ubuntu 14.10 (utopic)
  • Ubuntu 15.04 (vivid)
  • Ubuntu 15.10 (wily)
  • Ubuntu 16.10 (yakkety)
  • Ubuntu 17.04 (zesty)
  • Ubuntu 17.10 (artful)

Dokku will no longer distribute packages for Debian versions that are not stable or oldstable. This currently includes the following releases:

  • Debian 7 (wheezy)
  • Debian 8 (jessie)

Removed App report flags

The --git-sha flag was moved from the apps:report command to the git:report command.

App report output

When an app is not deployed, the apps:report command no longer shows the message not deployed. Please use the --deployed flag on ps:report instead to see if the app has been deployed.

Changes

App report flags

The following changes on the apps:report command were made in this release:

  • The --deploy-source flag was renamed to --app-deploy-source.
  • The --locked flag was renamed to --app-locked.

Network report flags

The following changes on the network:report command were made in this release:

  • The --network-listeners flag was renamed to --network-web-listeners.

Plugin Triggers

  • The network-get-port trigger was incorrectly documented to have the isHerokuishContainer argument as the third argument. The code has been fixed to respect the documentation.
  • The network-get-listeners trigger now takes an additional processType argument. If not specified, it defaults to web. This default will be removed in an upcoming release.

  • apps#apps_exists() is deprecated in favor of plugn trigger app-exists.
  • apps#apps_maybe_create() is deprecated in favor of plugn trigger app-maybe-create.
