Juju LXD Waiting for Machine Status | Resolved

If you have been coming across the Juju LXD “waiting for machine” message, you are in the right place. This is a status message that we run into when we use Juju to deploy a charm on an LXD cloud provider.

In fact, this message indicates that Juju is using a new virtual machine to deploy our application or service.

In other words, when we deploy a charm using Juju, it has to allocate and configure resources to run the application. If we use the LXD cloud provider, Juju will create LXD containers to host our services.

The “waiting for machine” status usually appears during the following scenarios:

1. Initial Deployment:

   When we deploy a charm or scale up the number of units for service, Juju has to create new LXD containers to host those units. This is when we come across the “waiting for machine” status until the containers are fully provisioned.
2. Resource Constraints:

   If the LXD cluster does not have enough available resources to create new containers, Juju may display the “waiting for machine” status.
3. Network Connectivity:

   In case there are network connectivity issues between the Juju controller and the LXD cluster, Juju will not be able to communicate with the LXD service. This leads to the “waiting for machine” status.
4. Provisioning Delay:

   The provisioning process may take some time, according to the performance of the infrastructure and the resources requested for the LXD containers.

Our experts would like to point out that the “waiting for machine” status is not an error message. In fact, it indicates that Juju is working on creating the containers for our deployment. The status will change in time to reflect the success or failure of the process.

Troubleshooting Tips

1. First, we have to check the status of the LXD cluster and ensure there are enough available resources for the deployment.
2. Next, verify the LXD cluster is accessible from the Juju controller. In addition, we have to ensure there are no network connectivity issues.
3. Then, monitor the Juju logs for error messages or issues related to the provisioning process.
4. Finally, we can wait for some time to let the provisioning process to complete, especially if we are deploying multiple units
