title: Ansible and YAML special characters
body: <p>I have a very complex command I need to run via the shell: command, but it has all kinds of special characters that I need to preserve. I also want to be able to add vars into the command line for multiple environments.</p>
  
  <p>How should I format this so I don't get all kinds of wacky errors. </p>
  
  <p>shell: OC_EDITOR="sed -i 's/node-selector:.*/node-selector: \"region=primary, zone=blah\"/'" oc edit namespace default</p>
  
  <p>Later I will change zone to a variable {{ zone }}</p>
