Deploy to Kubernetes using Kustomize

Magnus Hauge Bakke

I am trying to deploy changes to my cluster using `kubectl apply -k ./` in a pipeline. My pipeline looks like this:

pipelines:
  custom:
    update-ref:
      - step:
          script:
            - sed -E -i "s|([^-]- image:[^:]+).*|\1:$APP_COMMIT|g" deployments/app.yaml
            - git add deployments/app.yaml
            - git commit -m "[skip ci] Updating deployments/app.yaml with latest build number."
            - git push
            - pipe: atlassian/kubectl-run:1.1.6
              variables:
                KUBE_CONFIG: $KUBE_CONFIG
                KUBECTL_COMMAND: 'apply'
                KUBECTL_ARGS:
                  - '-k'
                RESOURCE_PATH: './'
                # WITH_DEFAULT_LABELS: 'false'

 But I get the following error:

<span>Traceback (most recent call last):</span><span>  File "/pipe.py", line 121, in <module></span><span>    <a href="http://pipe.run/" target="_blank" rel="noopener nofollow noreferrer">pipe.run</a>()</span><span>  File "/pipe.py", line 112, in run</span><span>    self.handle_apply()</span><span>  File "/pipe.py", line 77, in handle_apply</span><span>    self.update_labels_in_metadata(template_file, labels)</span><span>  File "/pipe.py", line 31, in update_labels_in_metadata</span><span>    yaml_doc['metadata'].setdefault('labels', {}).update(labels)</span><span>KeyError: 'metadata'</span><span>Status: Downloaded newer image for bitbucketpipelines/kubectl-run:1.1.6</span>

I have also tried turning off default labels.

After reviewing the code for kubectl-run I found that if the command is "apply" the -f parameter will be forced and it will only parse yaml-files (not directories).

Since I supplied a directory it would try to parse all the yaml-files inside, looking for metadata in each. kustomization.yaml does not have any metadata and this would lead to the error.

But if I added my whole command it would be parsed as any other command.

I updated my pipeline to the following:

pipelines:
  custom:
    update-ref:
      - step:
          script:
            - sed -E -i "s|([^-]- image:[^:]+).*|\1:$APP_COMMIT|g" deployments/app.yaml
            - git add deployments/app.yaml
            - git commit -m "[skip ci] Updating deployments/app.yaml with latest build number."
            - git push
            - pipe: atlassian/kubectl-run:1.1.6
              variables:
                KUBE_CONFIG: $KUBE_CONFIG
                KUBECTL_COMMAND: 'apply -k ./'
