The following playbook worked for me, but I just started with Ansible and
I'm wondering if I went about this wrong? I feel like I may have missed an
easier way to say: do something only after a package has finished
installing ...
tasks: - name: Install python3 with a specific command and register stdout
to a var command: sudo yum -y install python3 python3-pip register: varname
- name: Create a directory only after python3 has been installed file:
path: /home/ec2-user/newdirectory state: directory when:
varname.stdout.find("Complete!") != -1
