Vultr – Cloud Init Not Working

cloud-initvultr

I am new with Cloud-Init, I am trying to install tailscale and Docker with it, and some other packages

I tried several times and no luck and no error logs.

What I am doing wrong?

Here is my script:

#cloud-config

users:
    - name: ubuntu
        shell: /usr/bin/bash
        ssh_import_id: gh:skhaz
        sudo: ALL=(ALL:ALL) NOPASSWD:ALL

chpasswd:
    expire: false

apt_upgrade: true

apt:
    sources:
        docker
            source: deb [arch=amd64 trusted=yes] https://download.docker.com/linux/ubuntu focal stable
        tailscale:
            source: deb [arch=amd64 trusted=yes] https://pkgs.tailscale.com/stable/ubuntu focal main

packages:
    - docker-ce
    - tailscale
    - aria2
    - build-essential
    - vim
    - tmux

runcmd:
    - tailscale up -authkey='REDACTED'

    - ufw --force reset
    - ufw allow in on tailscale0 to any
    - ufw --force

If your yaml pasted correctly, your indentation is wrong and you're missing a : on your docker line:

Try this:

#cloud-config

users:
    - name: ubuntu
      shell: /usr/bin/bash
      ssh_import_id: gh:skhaz
      sudo: ALL=(ALL:ALL) NOPASSWD:ALL

chpasswd:
    expire: false

apt_upgrade: true

apt:
    sources:
        docker:
            source: deb [arch=amd64 trusted=yes] https://download.docker.com/linux/ubuntu focal stable
        tailscale:
            source: deb [arch=amd64 trusted=yes] https://pkgs.tailscale.com/stable/ubuntu focal main

packages:
    - docker-ce
    - tailscale
    - aria2
    - build-essential
    - vim
    - tmux

runcmd:
    - tailscale up -authkey='REDACTED'

    - ufw --force reset
    - ufw allow in on tailscale0 to any
    - ufw --force

Notice the indentation on lines 5-7, and the : at the end of line 16.

In general, for debugging cloud-init, there's a command to check your #cloud-config against a schema. On the launched instance you can run cloud-init schema --system. Also, you can check /var/log/cloud-init.log for any WARNING or Traceback. The log can be fairly verbose, but that can at least give you a starting point.
