Add helm dependency update SUMMARY Execute the helm dependency update under the hood when found dependencies block in Chart.yaml file. Support the execution of: Standalone dependency update by executing: helm dependency update CHART Inline dependency update when specifying the helm chart_repo_url by adding --dependency-update to the helm install command. ISSUE TYPE Feature Pull Request #191 COMPONENT NAME helm, helm_template ADDITIONAL INFORMATION There is a doc generated for history_max option for the helm module. I think that is not generated in the previous PR #164. There is others changes affect the docs/ folder when I run the collection_prep_add_docs -p . command. These changes are added in the last commit 64eab40. I let you decide rather we keep the commit or remove it. The --dependency-update insertion option is tested used a local helm chart repository create via docker. So here are the tasks that test this feature. Maybe if we create a GitHub repository for the helm chart, we can add this test code in the CI pipeline. # Test The update dependency with chart_repo_url - name: "Test chart without dependencies block and chart_repo_url defined" block: - name: "Test chart without dependencies block and chart_repo_url defined" helm: binary_path: "{{ helm_binary }}" name: test chart_ref: "ingress-nginx" chart_repo_url: https://kubernetes.github.io/ingress-nginx chart_version: "{{ chart_source_version | default(omit) }}" namespace: "{{ helm_namespace }}" create_namespace: yes register: release - assert: that: - "'--dependency-update' not in release.command" - "'upgrade' in release.command" success_msg: "Command does not contains '--dependency-update' options" fail_msg: "Command contains '--dependency-update' options" - name: "Test chart with dependencies block and chart_repo_url defined and replace True" block: - name: "Test chart with dependencies block and chart_repo_url defined and replace True" helm: binary_path: "{{ helm_binary }}" name: test1 chart_ref: "dep_up" chart_repo_url: http://repo:8080/charts chart_version: "{{ chart_source_version | default(omit) }}" namespace: "{{ helm_namespace }}" create_namespace: yes replace: true register: release - debug: var=release - assert: that: - "'--dependency-update' in release.command" - "'install' in release.command" success_msg: "Command contains '--dependency-update' options with helm install command" fail_msg: "Command not contains '--dependency-update' with helm install command" - name: "Test chart with dependencies block and chart_repo_url defined and replace False fails" block: - name: "Test chart with dependencies block and chart_repo_url defined and replace False fails" helm: binary_path: "{{ helm_binary }}" name: test2 chart_ref: "dep_up" chart_repo_url: http://repo:8080/charts chart_version: "{{ chart_source_version | default(omit) }}" namespace: "{{ helm_namespace }}" create_namespace: yes replace: false register: release ignore_errors: true - assert: that: - release.failed - release.msg == "'--dependency-update' hasn't been supported yet with 'helm upgrade'.
