## Container management

### :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.
:nerd_face: `oci-archive://` prefix can be used for `IMAGE` to specify a local file system path to an OCI formatted tarball.

Basic flags:

- :whale: `-a, --attach`: Attach STDIN, STDOUT, or STDERR
- :whale: :blue_square: `-i, --interactive`: Keep STDIN open even if not attached"
- :whale: :blue_square: `-t, --tty`: Allocate a pseudo-TTY
  - :warning: WIP: currently `-t` conflicts with `-d`
- :whale: `-sig-proxy`: Proxy received signals to the process (default true)
- :whale: :blue_square: `-d, --detach`: Run container in background and print container ID
- :whale: `--restart=(no|always|on-failure|unless-stopped)`: Restart policy to apply when a container exits
  - 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: `-q, --quiet`: Suppress the pull output
- :whale: `--pid=(host|container:<container>)`: PID namespace to use
- :whale: `--uts=(host)` : UTS namespace to use
- :whale: `--stop-signal`: Signal to stop a container (default "SIGTERM")
- :whale: `--stop-timeout`: Timeout (in seconds) to stop a container
- :whale: `--detach-keys`: Override the default detach keys

Platform flags:

- :whale: `--platform=(amd64|arm64|...)`: Set platform

Init process flags:

- :whale: `--init`: Run an init inside the container that forwards signals and reaps processes.
- :nerd_face: `--init-binary=<binary-name>`: The custom init binary to use. We suggest you use the [tini](https://github.com/krallin/tini) binary which is used in Docker project to get the same behavior.
  Please make sure the binary exists in your `PATH`.
  - Default: `tini`

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.

Network flags:

- :whale: `--net, --network=(bridge|host|none|container:<container>|ns:<path>|<CNI>)`: Connect a container to a network.
  - Default: "bridge"
  - `container:<name|id>`: reuse another container's network stack, container has to be precreated.
  - :nerd_face: `ns:<path>`: run inside an existing network namespace
  - :nerd_face: Unlike Docker, this flag can be specified multiple times (`--net foo --net bar`)
- :whale: `-p, --publish`: Publish a container's port(s) to the host
- :whale: `--dns`: Set custom DNS servers
- :whale: `--dns-search`: Set custom DNS search domains
- :whale: `--dns-opt, --dns-option`: Set DNS options
- :whale: `-h, --hostname`: Container host name
- :whale: `--add-host`: Add a custom host-to-IP mapping (host:ip). `ip` could be a special string `host-gateway`,
- which will be resolved to the `host-gateway-ip` in nerdctl.toml or global flag.
- :whale: `--ip`: Specific static IP address(es) to use. Note that unlike docker, nerdctl allows specifying it with the default bridge network.
- :whale: `--ip6`: Specific static IP6 address(es) to use. Should be used with user networks
- :whale: `--mac-address`: Specific MAC address to use. Be aware that it does not
  check if manually specified MAC addresses are unique. Supports network

- :nerd_face: `--cgroup-conf`: Configure cgroup v2 (key=value)
- :whale: `--blkio-weight`: Block IO (relative weight), between 10 and 1000, or 0 to disable (default 0)
- :whale: `--cgroupns=(host|private)`: Cgroup namespace to use
  - Default: "private" on cgroup v2 hosts, "host" on cgroup v1 hosts
- :whale: `--cgroup-parent`: Optional parent cgroup for the container

3. `nerdctl attach test` to attach to the container

Caveats:

- Currently only one attach session is allowed. When the second session tries to attach, currently no error will be returned from nerdctl.
  However, since behind the scenes, there's only one FIFO for stdin, stdout, and stderr respectively,
  if there are multiple sessions, all the sessions will be reading from and writing to the same 3 FIFOs, which will result in mixed input and partial output.
- Until dual logging (issue #1946) is implemented,
  a container that is spun up by either `nerdctl run -d` or `nerdctl start` (without `--attach`) cannot be attached to.

- :nerd_face: `--insecure-registry`: skips verifying HTTPS certs, and allows falling back to plain HTTP
- :nerd_face: `--host-gateway-ip`: IP address that the special 'host-gateway' string in --add-host resolves to. It has no effect without setting --add-host
  - Default: the IP address of the host

The global flags can be also specified in `/etc/nerdctl/nerdctl.toml` (rootful) and `~/.config/nerdctl/nerdctl.toml` (rootless).
See [`./config.md`](./config.md).
