Requirements
- A working connection and login to the Kubernetes cluster.
- A valid namespace selected with authorization to run pods.
- A test container pushed to the CCU docker registry.
Set up a Kubernetes job script
Download the Kubernetes samples and look at job script in example_1. Alternatively, create your own directory and file named "job_script.yaml". Edit the contents as follows and replace all placeholders with your data:
When we start this job, it will create a single container based on the image we previously uploaded to the registry on a suitable node which serves the selected namespace of the cluster.
> kubectl apply -f job_script.yaml
Checking in on the container
We first check if our container is running.
> kubectl get pods
# somewhere in the output you should see a line like this:
Now that you now the name of the pod, you can check in on the logs:
# replace xxxx with the code from get pods.
> kubectl logs tf-mnist-xxxx
or get some more information about the node the pod was placed on etc.
# replace xxxx with the code from get pods.
> kubectl describe pod tf-mnist-xxxx
