An Ansible summary

一开始通读一遍这个很不错，是最简单明确的 Python 教程，最适合快速了解。

For educational reasons I've decided to create my own CA. Here is what I learned.

Lets get some context first.

	map $http_origin $allow_origin {
	default "$http_origin";
	}

	map $request_method $cors_method {
	default "allowed";
	"OPTIONS" "preflight";
	}

	map $cors_method $cors_max_age {

	Would like to be able to check contents of json.items..labels[] and json.items..labels[].value from json below:

	I'm unsure how to get the contents of the generator from ansible / jinja2.

	- name: Test json
	debug: "msg={{ json.items\|map(attribute='metadata.labels') }}"

	$ ansible-playbook -i inv/dev k8s-redis.yml --extra-vars "@test-var.json"

	Gives me:

	---
	- name: Ansible tests playbook
	hosts: all
	remote_user: root

	tasks:
	- name: Check if mariadb-libs-5.5.44-2.el7.centos.x86_64 package is installed
	yum:
	list=mariadb-libs-5.5*x86_64
	register: pkg
