Azure DevOps pipeline kubectl task command: rollout unavailable

Question

Hi I am trying to implement the rollback for Kubernetes deployments using this guide, https://adrianbumbas.com/rollback-kubernetes-deployments-with-azure-devops-pipelines/. However, when adding a new kubectl task into the pipeline, I was unable to find the rollout command. I would like to know if there can be other alternative ways that I can achieve it. I appreciate the sharing of knowledge if you have previously encountered similar issue.

What Kubernetes version do you have in aks? in the documentation says, kubectl rollout is available in Kubernetes server version 1.7 or later. – Boxberry

@Boxberry my kubernetes version is 1.7.11 – Silverside

Answer 1

As suggested here already, you can use rollout as you would any other command, the below worked perfectly for me

- stage: Deploy_BVT
  displayName: Deploy BVT
  dependsOn: Build
  jobs:
  - deployment: Deploy_BVT
    pool:
      vmImage: $(vmImageName)
    environment: '$(envName).my_namespace'

...

- task: Kubernetes@1
  inputs:
  connectionType: 'Kubernetes Service Connection'
  namespace: 'my_namespace'
  command: 'rollout'
  arguments: 'restart deploy my_deployment'

You got this warning was because kubectl task command had a dropdowm list containing the following kubectl commands:

apply, create, delete, exec, expose, get, login, logout, logs, run, set, or top

From my test, even you got this warning, you still could run the pipeline, and pipeline could recognize rollout command. You may have a try.
