Setup Lxd

Task: set up LXD substrate

Goal

Install and configure LXD inside the sandbox VM and register it as a Juju cloud so that a Juju controller can be bootstrapped against it for machine charm deployments.

Steps

1. Run the setup script:

   $PROJECT_ROOT/development-sandbox/bin/setup-lxd.sh
   

   This is idempotent. Each step checks whether it has already been done. Wait for it to complete before proceeding.

2. Bootstrap a Juju controller. Use a descriptive controller name:

   juju bootstrap localhost lxd-ctrl
   

3. Create a working model:

   juju add-model testing
   

4. Verify the substrate is ready:

   juju status -m testing
   

Notes

• The localhost Juju cloud refers to the local LXD installation.
• If the lxd group membership message appears, open a new shell before running juju bootstrap to ensure the ubuntu user has LXD access.
• Machine charms deployed on LXD run in LXD containers, not Kubernetes pods. Commands like juju exec work normally. sudo k8s kubectl is not relevant for LXD deployments.
