Accessing the K3S cluster
Both the single node and high-availability (HA) deployment methods have a K3S node that is provisioned using Terraform. In the single node case, this is the cluster that actually hosts Azimuth and all its dependencies. In the HA case, this cluster is configured as a Cluster API management cluster for the HA cluster that actually runs Azimuth.
In both cases, the K3S node is deployed using Terraform and the IP address and SSH key
for accessing the node are in the Terraform state for the environment. The azimuth-config
repository contains a utility script -
seed-ssh - that will
extract these details from the Terraform state for the active environment and use them to
execute an SSH command to access the provisioned node.
Accessing an environment deployed using automation
If you are using seed-ssh to access an environment that is deployed using
automation, you still need to make sure that the
Python and Ansible dependencies are installed in order for the script to work:
Once on the node, you can use kubectl to inspect the state of the Kubernetes cluster. It
is already configured with the correct kubeconfig file:
$ ./bin/seed-ssh
ubuntu@azimuth-staging-seed:~$ kubectl get po -A
