0.6.0 Migration Guide

zero-downtime deployment

• You can now actually disable zero-downtime deployments per-app and per-process-type
  • Some config variables have been moved around
    • DOKKU_CHECKS_ENABLED has been migrated to DOKKU_CHECKS_SKIPPED
    • DOKKU_CHECKS_DISABLED is now a thing
    • The values for the above can be a comma-separated list of process-types or the literal string _all_
  • See the updated checks docs for more info

proxy port mapping

• You can now configure host -> container proxy port mappings
  • The UI is handled by the proxy interface plugin by setting the DOKKU_PROXY_PORT_MAP config variable in the format of scheme:host-port:container-port. The default nginx-vhosts proxy plugin supports both the http and https schemes.

calling the dokku binary

• Plugins should not call the dokku binary directly. Clients using the --app argument are potentially broken, amongst others, when doing so. Instead, please source the functions file for a given plugin when attempting to call dokku internal functions. As a result, the following dokku commands are no longer publicly exposed:
• dokku build
• dokku receive
• dokku release
• dokku tar:build
• dokku tar:build-locked
• dokku git:build
• dokku git:build-locked
