Running Alpine Linux using ChromeOS

· jswank's blog

I want to run an Alpine Linux container using ChromeOS.

Procedure #

  1. Start the CROSH shell (ctrl-alt-t).
  2. Connect to the termina container: vmc start termina
  3. Add a new LXD remote image source: lxc remote add canonical https://images.lxd.canonical.com --protocol=simplestreams
  4. Launch a new Alpine container: lxc launch canonical:alpine/edge my-alpine
  5. Connect to the new container: lxc exec my-alpine -- /bin/sh.

Comments #

Setup lxd for Remote Access #

1$ lxc config set core.https_address :8443
2$ lxc config set core.trust_password somepassword

Setup lxc on Penguin #

This allows lxc to be used in the default penguin container.

1$ sudo apt install lxd-client
2$ lxc remote add chromeos $(ip route show default | awk '{print $3}') --accept-certificate
3$ lxc remote set-default chromeos

Shared Storage #

Create a new storage volume and attach it to the container.

1$ lxc storage volume create default repos --type=filesystem  # create a new storage volume
2$ lxc storage volume set default repos security.shifted=true  # remap uids & gids for the volume
3$ lxc storage volume attach default repos alpine /home/jswank/repos  # attach the storage volume to the container

Alpine / Cloud Init #

Copy a file from a container to the host #

1(termina) chronos@localhost ~ $ lxc file pull penguin/home/jswank/repos/prose/alpine-chromeos-files/my-user-data /tmp/my-user-data

Start a cloud init Alpine container #

1(termina) chronos@localhost ~ $ lxc launch canonical:alpine/3.20/cloud test-alpine --config=user.user-data="$(cat /tmp/my-user-data)"
2$ lxc config device add alpine-test repos disk pool=default source=repos path=/home/cli/repos

Connect to a running Alpine container #

1$ lxc exec test-alpine -- su - cli
