I'm trying to test out the Ubuntu autoinstall and I'm struggling to figure out how to work with the apt section.

My goal is to install for example git and docker, which would look like that on a regular terminal installation:

#Python3.6
add-apt-repository ppa:deadsnakes/ppa -y
apt-get update
apt-get install python3.6 -y
#Docker -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
apt-get -y update
apt-get -y install docker-ce docker-ce-cli containerd.io

I read the documentation of the autoinstall - https://ubuntu.com/server/docs/install/autoinstall-reference

And the referenced documentation of Curtin at - https://curtin.readthedocs.io/en/latest/topics/apt_source.html

However, it's not soo clear to me who should I add the repositories.

Would appreciate any guidance or a working example.

This config snippet adds the repositories to the installed system

#cloud-config
autoinstall:
  apt:
    preserve_sources_list: false
    primary:
      - arches: [amd64, i386]
        uri: http://us.archive.ubuntu.com/ubuntu
      - arches: [default]
        uri: http://ports.ubuntu.com/ubuntu-ports
    sources:
      deadsnakes-ppa:
        source: ppa:deadsnakes/ppa
      docker:
        source: deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable

Ubuntu auto install uses cloud-init yaml files which is a brilliant way of doing unattended installs of Ubuntu. However there is a bit of a learning curve.

The cloud-init documentation has this as an example: https://cloudinit.readthedocs.io/en/latest/topics/examples.html#add-primary-apt-repositories

For example, the cloud-init yaml user-data for installing and running docker.io:

#cloud-config
timezone: 'Europe/London'
package_update: 'true'
packages:
  - build-essential
  - docker.io
write_files:
  - path: /etc/systemd/system/container.service
    owner: root:root
    permissions: '0755'
    content: |
        [Unit]
        Description=Run container
        Requires=docker.service
        After=docker.service

    [Service]
    Restart=always
    ExecStartPre=-/usr/bin/docker rm container
    ExecStart=/usr/bin/docker run --rm --name container hello-world
    ExecStop=/usr/bin/docker stop -t 2 container




runcmd:


    

  • systemctl start container
    • 

  • systemctl enable container
