!!! 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 docker-registry regsecret --docker-server=<yourRegistry> --docker-username=<containerRegistryUser> --docker-password=<containerRegistryPassword> --dry-run=true --output=json'` + "`" + ``,
