Can I put a eb extension container command on multiple lines and if I can how?

Question

All I've found about this is: https://forums.aws.amazon.com/thread.jspa?threadID=112988

I know that I can do this:

container_commands:
   07_run_command:
      "mkdir -p /var/cache/tomcat8/temp/.m2/repository && chmod 777"

But can I do this?

container_commands:
   07_run_command:
      mkdir -p /var/cache/tomcat8/temp/.m2/repository && 
      chmod 777

And do I still need the && to separate the commands or are they executed as separate commands? or is it still only one command?

Answer 1

This can be done via YAML's literal block scalar, as follows:

container_commands:
  07_run_command: |
      mkdir -p /var/cache/tomcat8/temp/.m2/repository
      chmod 777
