I'm using Ansible to create a pm2 service on a EC2 / Ubuntu instance. Below is the script. When I run it, PM2 is installed and the service is enabled. When I run pm2 list, I don't the see the service, but I can grep it (ps aux | grep node) and see that it's running. It also seems like a shadow copy of pm2 is running and loading the app, but I can't seem to control it.
- hosts: comm sudo: yes tasks: - npm: name=pm2 global=yes - name: configure pm2 to restart on startup shell: pm2 startup ubuntu >& /dev/null chdir=~/ executable=/bin/bash sudo: yes sudo_user: root - command: sudo env PATH=$PATH:/usr/bin pm2 startup ubuntu -u ubuntu sudo: yes - command: /usr/bin/pm2 save - command: /usr/bin/pm2 start /home/ubuntu/something/app.js --name something

This playbook is not idempotent, the
shell
task is going to run every time the playbook is run, you need to supply acreates
argument to that task.In the current version of PM2:
Also, the use of
sudo
is redundant, as it is already specified globally above, and the default is tosudo
toroot
, so that's redundant as well.Additionally, once there's an
init
script for the service, it would be better to use theservice
module to manage it.
