vagrant-state-change-listener

Vagrant plugin for listening vm state changes and executing actions on changes.

foo@bar:~$ vagrant plugin install vagrant-state-change-listener

Use listen-state-changes command to listen vm state changes. When state is changed (e.g., from running to stopped), command executes given actions (shell commands).

foo@bar:~$ vagrant listen-state-changes <vm name> <actions> [options]

<vm name> - name of virtual machine

<actions> - shell commands to execute after state change

-f (--first-state) FSTATE - If vm changes it's state from FSTATE, plugin executes <actions>

-s (--second-state) SSTATE - If vm changes it's state to SSTATE, plugin executes <actions>"

-l (--latency SECONDS) - Delay (in seconds) between checking for changes. Default: 1 sec

-a (--auto-stop) - Stop listening after first state change (after executing <actions>)

foo@bar:~$ vagrant listen-state-changes default 'echo Changed!'

When vm with name default changes it's state, Changed! is printed to console. Terminal is blocked until the user manually terminates command

foo@bar:~$ vagrant listen-state-changes default 'echo Changed!' -a

When vm with name default changes it's state, Changed! is printed to console and command terminates

foo@bar:~$ vagrant listen-state-changes default 'echo Changed!' -f running

When vm with name default changes it's state from running to any other state, Changed! is printed to console

foo@bar:~$ vagrant listen-state-changes default 'echo Changed!' -s stopped

When vm with name default changes it's state to stopped from any other state, Changed! is printed to console

foo@bar:~$ vagrant listen-state-changes default 'echo Changed!' -f running -s stopped

When vm with name default changes it's state from running to stopped, Changed! is printed to console

foo@bar:~$ vagrant listen-state-changes default 'echo Changed!' -l 10

When vm with name default changes it's state, Changed! is printed to console. Delay between state checking - 10 sec\
