### :whale: :blue_square: nerdctl run
Run a command in a new container.
Usage: `nerdctl run [OPTIONS] IMAGE [COMMAND] [ARG...]`
:nerd_face: `ipfs://` prefix can be used for `IMAGE` to pull it from IPFS. See [`ipfs.md`](./ipfs.md) for details.
Basic flags:
- :whale: :blue_square: `-i, --interactive`: Keep STDIN open even if not attached"
- :whale: :blue_square: `-t, --tty`: Allocate a pseudo-TTY

- Default: "no"
- always: Always restart the container if it stops.
- on-failure[:max-retries]: Restart only if the container exits with a non-zero exit status. Optionally, limit the number of times attempts to restart the container using the :max-retries option.
- unless-stopped: Always restart the container unless it is stopped.
- :whale: `--rm`: Automatically remove the container when it exits
- :whale: `--pull=(always|missing|never)`: Pull image before running
- Default: "missing"
- :whale: `--pid=(host|container:<container>)`: PID namespace to use

Isolation flags:
- :whale: :blue_square: :nerd_face: `--isolation=(default|process|host|hyperv)`: Used on Windows to change process isolation level. `default` will use the runtime options configured in `default_runtime` in the [containerd configuration](https://github.com/containerd/containerd/blob/master/docs/cri/config.md#cri-plugin-config-guide) which is `process` in containerd by default. `process` runs process isolated containers. `host` runs [Host Process containers](https://kubernetes.io/docs/tasks/configure-pod-container/create-hostprocess-pod/). Host process containers inherit permissions from containerd process unless `--user` is specified then will start with user specified and the user specified must be present on the host. `host` requires Containerd 1.7+. `hyperv` runs Hyper-V hypervisor partition-based isolated containers. Not implemented for Linux.
