Helm Charts and repositories
How to use external Helm repositories in Codefresh pipelines
The “Helm Charts” page allows you to integrate with external Helm repositories and Helm charts. Note that all Codefresh accounts already include a built-in Helm repository. Using external Helm repositories is optional.
Adding an external Helm repository
By default, we show you charts from the official Helm repository but you can easily add your own:
In the “Helm Charts” page, click on the “Add Repository” button on the top right.
In the dialog that opened, name your repository, and specify it’s URL. The URL should not include the specific path to
If your repository doesn’t require authentication, click ‘Save’ and you are done.
For more details on adding extra Helm repositories see the Helm integration page.
Using a Helm Repository in a Codefresh pipeline
Once connected, any Helm repository context can be injected into pipelines by selecting “Import from shared configuration” (under “Environment Variables” section) and selecting the name of the repository.
The repository settings will be injected as environment variables into the pipeline so you can use them as you wish.
If you are using the Helm step, it will use these settings to connect to your authenticated repository automatically. More info on the Codefresh Helm step can be found in the Helm Usage Guide.
Install chart from your Helm repository
In the “Helm Charts” page, locate the chart you would like to install, and click on the Install button.
In the dialog that opened:
- Name your release and choose a version of the chart to install.
- Cluster information:
- Select a Kubernetes cluster and namespace to install to. This should be pre-configured in the Kubernetes Integration, see here.
- Optionally, select the namespace where Tiller is at
- The default values that was provided with the chart will show up, you can press the edit button to view and override them.
- When the default values yaml was changed, it will be provided to helm install as a values file. You can revert back your overriding changed by clicking on the revert button (next to the edit button).
- You can provide additional values files by opening the ‘Import from configuration’ drop down list and selecting “Add new context of type: YAML”. Insert your values YAML here and save. The YAML will be saved for future usage so that next time simply select it from the drop-down list.
- Additionally, you can override some values by adding them in the “Override set variables section”
The order of values configurations matter for helm, values provided last overrides values provided earlier. In the Chart Install wizard values are provided in the following order:
- Default Values in the chart (implicitly part of the chart).
- Overridden default values (provided as values file, provided only if edited by the user).
- Supplied values files from Yaml Shared Configuration.
- Override variables are provided as
From the same dialog you can also provide your own pipeline to be used (instead of the one offered by Codefresh). If you select a custom pipeline the following variables will be available to you:
CF_HELM_RELEASE- name of release
CF_HELM_KUBE_CONTEXT- kubectl context name of target cluster (cluster name from dashboard)
CF_HELM_NAMESPACE- Tiller Namespace if you use Helm 2
CF_HELM_INSTALLATION_NAMESPACE- desired namespace for the release
CF_HELM_CHART_VERSION- Chart Version,
CF_HELM_CHART_NAME- Chart Name
CF_HELM_CONTEXTS- values from shared configuration
CF_HELM_VALUES- extra values
CF_HELM_SET- extra values,
CF_HELM_CHART_REPO_URL- URL of Chart repository
CF_HELM_COMMIT_MESSAGE- Message to show in Helm GUI,
Finally click on Install. You can observe the newly installed release on the “Helm Releases” page.
You can also install Helm releases from any Helm environment board.
