The Consul on Kubernetes CLI tool enables you to manage Consul with the `consul-k8s` command instead of direct interaction with Helm, kubectl, or Consul’s CLI. Learn about commands, their flags, and review examples in this reference guide.
| <nobr>`-auto-approve`</nobr> | Boolean value that enables you to skip the installation confirmation prompt. | `false` |
| <nobr>`-dry-run`</nobr> | Boolean value that validates the installation and returns a summary. | `false` |
| <nobr>`-config-file`</nobr> | String value that specifies the path to a file containing custom installation configurations, e.g., Consul Helm chart values file. <br/> You can use the `-config-file` flag multiple times to specify multiple files. | none |

The following example commands install Consul on Kubernetes using custom values, files, or strings that are set via flags. The underlying Consul-on-Kubernetes Helm chart uses the flags to customize the installation. The flags are comparable to the `helm install` [flags](https://helm.sh/docs/helm/helm_install/#helm-install).
| <nobr>`-all-namespaces`, `-A`</nobr> | `Boolean` List pods in all Kubernetes namespaces. | `false` |
| <nobr>`-namespace`, `-n`</nobr> | `String` The Kubernetes namespace to list proxies in. | Current [kubeconfig](https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/) namespace. |
Consul clusters connected using mesh federation. Read more about [Consul Mesh Federation](/consul/docs/k8s/deployment-configurations/multi-cluster/kubernetes).
| <nobr>`-namespace`, `-n`</nobr> | `String` The namespace where the target Pod can be found. | Current [kubeconfig](https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/) namespace. |
| <nobr>`-output`, `-o`</nobr> | `String` Output the Envoy configuration as 'table', 'json', or 'raw'. | `'table'` |
| <nobr>`-clusters`</nobr> | `Boolean` Filter output to only show clusters. | `false` |
| <nobr>`-endpoints`</nobr> | `Boolean` Filter output to only show endpoints. | `false` |
| <nobr>`-listeners`</nobr> | `Boolean` Filter output to only show listeners. | `false` |
| <nobr>`-routes`</nobr> | `Boolean` Filter output to only show routes. | `false` |
| <nobr>`-secrets`</nobr> | `Boolean` Filter output to only show secrets. | `false` |
| <nobr>`-address`</nobr> | `String` Filter clusters, endpoints, and listeners output to only those with endpoint addresses which contain the given value. | `""` |
| <nobr>`-fqdn`</nobr> | `String` Filter cluster output to only clusters with a fully qualified domain name which contains the given value. | `""` |
| <nobr>`-port`</nobr> | `Int` Filter endpoints output to only endpoints with the given port number. | `-1` which does not filter by port |
The `status` command provides an overall status summary of the Consul on Kubernetes installation. It also provides the configuration that was used to deploy Consul K8s and information about the health of Consul servers and clients. This command does not take in any flags.
| <nobr>`-auto-approve`</nobr> | Boolean value that enables you to skip the removal confirmation prompt. | `false` |
| <nobr>`-name`</nobr> | String value for the name of the installation to remove. | none |
| <nobr>`-namespace`</nobr> | String value that specifies the namespace of the Consul installation to remove. | `consul` |
| <nobr>`-timeout`</nobr> | Specifies how long to wait for the removal process to complete before timing out. The value is specified with an integer and string value indicating a unit of time. <br/> The following units are supported: <br/> `ms` (milliseconds)<br/>`s` (seconds)<br/>`m` (minutes) <br/>`h` (hours) <br/>In the following example, removal will timeout after one minute:<br/> `consul-k8s uninstall -timeout 1m` | `10m` |
| <nobr>`-wipe-data`</nobr> | Boolean value that deletes PVCs and secrets associated with the Consul installation during installation. <br/> Data will be removed without a verification prompt if the `-auto-approve` flag is set to `true`. | `false` <br/> Instructions for removing data will be printed to the console. |
| <nobr>`--help`</nobr> | Prints usage information for this option. | none |
See [Global Options](#global-options) for additional commands that you can use when uninstalling Consul from Kubernetes.
#### Example Command
The following example command immediately uninstalls Consul from the `my-ns` namespace with the name `my-consul` and removes PVCs and secrets associated with the installation without asking for verification:
The `upgrade` command upgrades the Consul on Kubernetes components to the current version of the `consul-k8s` cli. Prior to running `consul-k8s upgrade`, the `consul-k8s` CLI should first be upgraded to the latest version as described [Upgrade the Consul K8s CLI](#upgrade-the-consul-k8s-cli)

| <nobr>`-set-string`</nobr> | String value that enables you to set a customizable string value. This flag is comparable to the `helm upgrade --set-string` <br/> flag. You can use the `-set-string` flag multiple times to specify multiple strings. <br/> Consul Helm chart values are supported. | none |
