ROS Startup Script

RancherOS
5

So, I’v tried to reproduce and here’s what I’ve got. My cloud-config is:

#cloud-config
write_files:
  - path: /opt/rancher/bin/start.sh
    permissions: "0755"
    owner: root
    content: |
      #!/bin/bash
      echo "I'm doing things on start" > /opt/start-sh-did-this

After I’ve logged in I can see /opt/start-sh-did-this file is there with the expected content.

@tjmcs Docker cannot be used in these startup scripts as docker service starts after console in v0.4.0+. The best way to run docker containers on start is run them as services (I admit, I should spend more time on the docs), e.g. like with this cloud-config (adapted from @Jacob_Gadikian’s docker-run command above, this one runs Rancher Agent v0.8.2 as a privileged container bind-mounting /var/run/docker.sock):

#cloud-config
rancher:
  services:
    rancher-agent:
      image: rancher/agent:v0.8.2
      command: http://192.168.100.104:8080/v1/scripts/skipped-the-base64-stuff
      privileged: true
      volumes:
      - /var/run/docker.sock:/var/run/docker.sock
