bitrise-machine

Bitrise Machine - manage bitrise CLI runner hosts

Requirements

• vagrant
• bitrise-bridge for communication with the host

Cleanup modes

IMPORTANT: if you want to change a config's Cleanup Mode, first make sure that the machine/VM is not running, e.g. by running bitrise-machine destroy. Only after that you should change the Cleanup Mode in the config!

• rollback : runs vagrant snapshot pop to clean up
  • requires at least vagrant v1.8.0
  • SESSION: NOT SUPPORTED
• recreate : runs vagrant destroy -f and then vagrant up to clean up
  • bitrise-machine cleanup is the same as bitrise-machine destroy && bitrise-machine setup
  • SESSION: full session handling support, init session when VM created
• destroy : runs vagrant destroy -f to cleanup, and allows/requires bitrise-machine setup (to create the Virtual Machine with vagrant up)
  • useful for on-demand conigurations, where you might want to have periods when the virtual machine/host is not created
  • bitrise-machine cleanup only cleans up / destroys the virtual machine, it does not recreate it. You have to run bitrise-machine setup to create a new one after a cleanup.
  • SESSION: full session handling support, init session when VM created
• custom-command : runs vagrant CUSTOM-COMMAND to clean up, or vagrant up in case the Virtual Machine is not yet created
  • useful for provider plugins which add custom vagrant actions, which can be used for cleanup. For example the vagrant-digitalocean plugin adds a rebuild command to vagrant and makes a cleanup / re-build faster than re-creating the Virtual Machine with vagrant destroy and vagrant up.
  • SESSION: NOT SUPPORTED

Session

Bitrise Machine exposes a "session time id" as an environment variable, which can be used in the Vagrantfile.

Where session is supported, this "session time id" persists between a setup and a destroy, so the session time id will be the same during bitrise-machine setup and the following bitrise-machine destroy/cleanup, and will be re-generated at the next "vagrant up".

This session time id can be used to e.g. include it in the Virtual Machine ID, to help with unique ID generation, as the ID will be kept from "vagrant up" to "vagrant destroy", and the next "vagrant up" will generate a new session (time id).

Do not depend on session handling in recreate modes which do not support session! See the cleanup mode list above for which modes support support it!

The environment variable is: BITRISE_MACHINE_SESSION_TIME_ID

Format: YYYYMMDDHHMMSS Example: 20170215093215

TODO

• complete restructure: make everything session based
  • e.g. session.Start should create the SSH keys too
  • and session.End should delete them
• use Interface for "lifecycle handlers", one for each cleanup mode, so the common code just determines which handler to use (based on the cleanup mode), and then calls the handler's Setup, Destroy, Cleanup, ... methods, instead of doing this logic inline in every function (e.g. doCleanup)
