How to Deploy With Helm Using HelmDeploy in Azure Pipelines

HelmDeploy@0 runs helm upgrade with install against your cluster so a release is created or updated in one step.

Install the Helm CLI with HelmInstaller@1, then run HelmDeploy@0 with command: upgrade, your chart path, release name, and --set overrides.

Steps

• Add HelmInstaller@1 to pin the Helm version.
• Add HelmDeploy@0 with command: upgrade and install: true.
• Set releaseName, chartType: FilePath, and chartPath.
• Pass image tags through overrideValues.

azure-pipelines.yml

pool:
  vmImage: ubuntu-latest
steps:
  - task: HelmInstaller@1
    inputs:
      helmVersionToInstall: '3.14.0'
  - task: HelmDeploy@0
    inputs:
      connectionType: 'Kubernetes Service Connection'
      kubernetesServiceConnection: 'aks-prod'
      namespace: 'web'
      command: upgrade
      chartType: FilePath
      chartPath: 'charts/web'
      releaseName: 'web'
      install: true
      overrideValues: 'image.tag=$(Build.BuildId)'

Gotchas

• Without install: true, the first deploy fails because the release does not yet exist.
• Comma-separate multiple overrideValues; do not add stray spaces around the equals sign.
