ASAB Maestro bootstrap

The bootstrap is a process of how to deploy ASAB Maestro on the new cluster node.

Bootstap using Docker

$ docker run -it --rm --pull always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /opt/site:/opt/site \
  -v /opt/site/docker/conf:/root/.docker/ \
  -v /data:/data \
  -e NODE_ID=`hostname -s` \
  --network=host \
  pcr.teskalabs.com/asab/asab-governator:stable \
  python3 -m governator.bootstrap

Bootstrap using Podman

The Podman deployment is inherently root-less, adding extra layer of the security to the deployment.

Note

Version 4+ or Podman is strongly recommended.

This is how to install Podman to Ubuntu 22.04 LTS:

$ export ubuntu_version='22.04'
$ export key_url="https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/unstable/xUbuntu_${ubuntu_version}/Release.key"
$ export sources_url="https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/unstable/xUbuntu_${ubuntu_version}"

$ echo "deb $sources_url/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:unstable.list
$ curl -fsSL $key_url | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/devel_kubic_libcontainers_unstable.gpg > /dev/null
$ sudo apt update
$ sudo apt install podman

Configure Podman:

$ systemctl --user start podman.socket
$ systemctl --user enable podman.socket
$ sudo ln -s /run/user/${UID}/podman/podman.sock /var/run/docker.sock

$ loginctl enable-linger ${USER}

Prepare the OS filesystem layout:

$ sudo mkdir /opt/site
$ sudo chown ${USER} /opt/site
$ mkdir -p /opt/site/docker/conf

$ sudo mkdir /data
$ sudo chown ${USER} /data

Launch the bootstrap:

$ podman run -it --rm --pull always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /opt/site:/opt/site \
  -v /opt/site/docker/conf:/root/.docker/ \
  -v /data:/data \
  -e NODE_ID=`hostname -s` \
  --network=host \
  pcr.teskalabs.com/asab/asab-governator:stable \
  python3 -m governator.bootstrap
