Puppet Node Purging via API

When you're decomissioning a machine that has been managed by Puppet you may want to programatically clean up the node. There are two parts to this:

• revoking and deleting the certificate of the node in Puppet's CA
• deactivating the node in PuppetDB

The following should work for Puppet 4.x and Puppet DB 4.x (including Puppet Enterprise 2016.4.x, 2017.1.x, 2017.2.x).

I've used certificate based auth, and the examples are being run from the puppet master so make use of existing certificates for authentication. When run remotely the cacert, certificate and corresponding private key for authentication will need to be present.

Set secrets as env variables in docker

This script will read your secret file and set each line as an env variable in your container.

How to use it

I' assuming that you already has a entrypoint file in your Dockerfile. So now, you need to copy and paste the contents of set_env_secrets.sh to your entrypoint(you don't need the first line).

Now, you need to create a secret, the name could be whatever you like. I'm using the name of my application as a pattern for my secrets name. For this example, my secret name will be super-project and the content will be.
