### Kubernetes stack and context support
**Deprecated in Release: v20.10**
**Removed in Release: v21.xx**
Following the deprecation of [Compose on Kubernetes](https://github.com/docker/compose-on-kubernetes), support for
Kubernetes in the `stack` and `context` commands in the docker CLI is now marked as deprecated as well.
Following the deprecation of [Compose on Kubernetes](https://github.com/docker/compose-on-kubernetes),
support for Kubernetes in the `stack` and `context` commands has been removed from
the cli, and options related to this functionality are now either ignored, or may
produce an error.
The following command-line flags are removed from the `docker context` subcommands:
- `--default-stack-orchestrator` - swarm is now the only (and default) orchestrator for stacks.
- `--kubernetes` - the kubernetes endpoint can no longer be stored in `docker context`.
- `--kubeconfig` - exporting a context as a kubeconfig file is no longer supported.
The output produced by the `docker context inspect` subcommand no longer contains
information about `StackOrchestrator` and `Kubernetes` endpoints for new contexts.
The following command-line flags are removed from the `docker stack` subcommands:
- `--kubeconfig` - using a kubeconfig file as context is no longer supported.
- `--namespace` - configuring the kubernetes namespace for stacks is no longer supported.
- `--orchestrator` - swarm is now the only (and default) orchestrator for stacks.
The `DOCKER_STACK_ORCHESTRATOR`, `DOCKER_ORCHESTRATOR`, and `KUBECONFIG` environment
variables are no longer used, and ignored.
