deploy-util

Helper script to be used on the tsuru deploy and start events.

Usage

To have the deploy-util script deployed with the app image add the following line to the tsuru.yml hooks:build hook:

- curl -L https://github.com/edukorg/deploy-util/raw/master/deploy-util.sh -o deploy-util.sh && chmod +x deploy-util.sh

To run the default actions for the deploy event (including generate the APP_EXTRA_ENV file with the APP_CURRENT_VERSION) add the following line:

- ./deploy-util.sh run_on_tsuru_deploy

To run the default actions for the start event (including configure the APP_CURRENT_VERSION and TSURU_NONE internal env vars`) configure the Procfile processes like this:

web: ./deploy-util.sh run_tsuru_app npm start

The run_tsuru_app action will run the default actions to configure the environment and then will run the command as specifiec (npm start in this example).

The script is supposed to be executed with an action as it's first argument. It run that action with using the remaining arguments (options) as the action options.

Modifying the script

To create new action just create a function and add it name to the ACTIONS array. This is enough to make a new action avaiable. Any additional parameters used in the command line will be sent to the function (they can be accessed normaly with $1, $2, $@, shift, etc)

This is a bash script and it has some limitations, so it's important to remember:

• always add a final \ after adding a new action to the ACTIONS array
• you can't call functions defined after your function
• use the set -e in the beggining of your function if you want it to stop on every unexpected error
