For every release of Consul on Kubernetes, a Helm chart, `consul-k8s-control-plane` binary and a `consul-k8s` CLI binary is built and distributed through a single version. When deploying via Helm, the recommended best path for upgrading Consul on Kubernetes, is to upgrade using the same `consul-k8s-control-plane` version as the Helm Chart, as the Helm Chart and Control Plane binary are tightly coupled.
## Supported Consul versions
## Supported Consul and Kubernetes versions
Consul Kubernetes versions all of its components (`consul-k8s` CLI, `consul-k8s-control-plane`, and Helm chart) with a single semantic version. When installing or upgrading to a specific versions, ensure that you are using the correct Consul version with the compatible `consul-k8s` helm chart and/or CLI.

Supported versions of Envoy for Consul versions are also found in [Envoy - Supported Versions](/docs/connect/proxies/envoy#supported-versions). The recommended best practice is to use the default version of Envoy that is provided in the Helm values.yml file, as that is the version that has been tested with the default Consul and Consul Kubernetes binaries for a given Helm chart.
Supported versions of Envoy and `consul-dataplane` (for Consul K8s 1.0 and above) for Consul versions are also found in [Envoy - Supported Versions](/docs/connect/proxies/envoy#supported-versions). Starting with `consul-k8s` 1.0, `consul-dataplane` will include a bundled version of Envoy. The recommended best practice is to use the default version of Envoy or `consul-dataplane` that is provided in the Helm `values.yaml` file, as that is the version that has been tested with the default Consul and Consul Kubernetes binaries for a given Helm chart.
