  longDescription: |-
    Deployment to Kubernetes test or production namespace within the specified Kubernetes cluster.

    !!! note "Deployment supports multiple deployment tools"
        Currently the following are supported:

        * [Helm](https://helm.sh/) command line tool and [Helm Charts](https://docs.helm.sh/developing_charts/#charts).
        * [kubectl](https://kubernetes.io/docs/reference/kubectl/overview/) and `kubectl apply` command.

    ## Helm
    Following helm command will be executed by default:

    ```
    helm upgrade <deploymentName> <chartPath> --install --force --namespace <namespace> --wait --timeout <helmDeployWaitSeconds> --set "image.repository=<yourRegistry>/<yourImageName>,image.tag=<yourImageTag>,secret.dockerconfigjson=<dockerSecret>,ingress.hosts[0]=<ingressHosts[0]>,,ingress.hosts[1]=<ingressHosts[1]>,...
    ```

    * `yourRegistry` will be retrieved from `containerRegistryUrl`
    * `yourImageName`, `yourImageTag` will be retrieved from `image`
    * `dockerSecret` will be calculated with a call to `kubectl create secret generic <containerRegistrySecret> --from-file=.dockerconfigjson=<dockerConfigJson> --type=kubernetes.io/dockerconfigjson --insecure-skip-tls-verify=true --dry-run=client --output=json`

          There are two supported ways for the template rendering:

          ```

          Recommendation is to use custom values and pass them via parameter `helmValues`.<br />
          Since helm supports multiple files on top of the `values.yaml`, landscape-specific attributes can be passed via a specific file.
