Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

If you want to check whether a node run_list includes a specific role (upon expansion), then you could use role? method on the Node object:

node.role?('name')

Alternatively, you can see whether either would work for you:

node.roles.include?('name')

node.run_list?('role[name]')

Go to the egghead website, i.e. Building a React.js App

run

$.each($('h4 a'), function(index, video){
  console.log(video.href);
});

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

-# delete local tag '12345'
-git tag -d 12345
-# delete remote tag '12345' (eg, GitHub version too)
-git push origin :refs/tags/12345
-# alternative approach
-git push --delete origin tagName
-git tag -d tagName

	// kills long running ops in MongoDB (taking seconds as an arg to define "long")
	// attempts to be a bit safer than killing all by excluding replication related operations
	// and only targeting queries as opposed to commands etc.

	killLongRunningOps = function(maxSecsRunning) {
	currOp = db.currentOp();
	for (oper in currOp.inprog) {
	op = currOp.inprog[oper-0];
	if (op.secs_running > maxSecsRunning && op.op == "query" && !op.ns.startsWith("local")) {
	print("Killing opId: " + op.opid
