Upgrade Kustomize version

To change the Kustomize binary used by Rosco, mount a volume and use an initContainer to replace the original binary.
Perform the following steps:

  1. Create the file following file if it does not already exist: ~/.hal/default/service-settings/rosco.yml.
  2. Add the following volume information to the file:

       - id: shared-volume
         type: emptyDir
         mountPath: /packer/kustomize
    • This example uses an _emptyDir_ type for the volume type.
    • The mounthPath is the directory where the existing Kustomize binary is located.
  3. In the ~/.hal/config file, add an initContainer:

           - name: kustomize-binary
             image: tutum/curl:latest
             command: ["/bin/sh", "-c"]
             args: ["curl -s -L https://github.com/kubernetes-sigs/kustomize/releases/download/kustomize%2Fv3.5.4/kustomize_v3.5.4_linux_amd64.tar.gz | tar xvz -C /tmp"]
             - name: shared-volume
               mountPath: /tmp
    • Replace the URL in the args attribute with the URL for the Kustomize version that you want to use. In the example, the URL points to version 3.5.4.
    • Set the name for the volumeMounts to the same value as the volume‚Äôs ID in the rosco.yml file from step 2.
  4. Apply the changes: hal deploy apply.

  5. Enter into the Rosco pod: kubectl exec -it <rosco-pod> bash.
  6. Go to the Kustomize directory: cd /packer/kustomize. If you enter the ls command, you should see the new binary.
  7. Check the Kustomize version: ./kustomize version.
    The command returns information similar to the following:

     {Version:kustomize/v3.5.4 GitCommit:3af514fa9f85430f0c1557c4a0291e62112ab026 BuildDate:2020-01-11T03:12:59Z GoOs:linux GoArch:amd64}
