yaml-ansible

This is a sampling of yaml experiments working with and without Ansible to test capabilities and see how the YAML translates.

NOTE: YAML version is 1.1, that's what Ansible wants.

It's beneficial to brew install node and npm install -g js-yaml to use this.

Useful aliases:

alias jsonpp='python -m json.tool'
alias jsontoyaml='ruby -ryaml -rjson -e "puts YAML.dump(JSON.parse(STDIN.read))"'
alias yamltojson='ruby -rjson -ryaml -e "puts JSON.pretty_generate(YAML.load(STDIN.read))"'

Example using js-yaml

if parsing fails, error message shown else the yaml is output in json

js-yaml yaml_vars_demo.yml

I like to see how YAML transforms back (uses the aliases above)

js-yaml yaml_vars_demo.yml | jsontoyaml

Running with the playbook

This is noted at the header of playbook.yml

# run the playbook on localhost (that's what "," yields)
ansible-playbook -i "," playbook.yml -v
