Flags:
--address string containerd address, optionally with "unix://" prefix [$CONTAINERD_ADDRESS] (aliases: -a, -H, --host) (default "/run/containerd/containerd.sock")
--bridge-ip string IP address for the default nerdctl bridge network [$NERDCTL_BRIDGE_IP]
--cdi-spec-dirs strings The directories to search for CDI spec files. Defaults to /etc/cdi,/var/run/cdi (default [/tmp/.config/cdi,/run/user/1100/cdi])
--cgroup-manager string Cgroup manager to use ("cgroupfs"|"systemd") (default "none")
--cni-netconfpath string cni config directory [$NETCONFPATH] (default "/tmp/.config/cni/net.d")
--cni-path string cni plugins binary directory [$CNI_PATH] (default "/opt/cni/bin")
--data-root string Root directory of persistent nerdctl state (managed by nerdctl, not by containerd) (default "/tmp/.local/share/nerdctl")
--debug debug mode
--debug-full debug mode (with full output)
--experimental Control experimental: https://github.com/containerd/nerdctl/blob/main/docs/experimental.md [$NERDCTL_EXPERIMENTAL] (default true)
-h, --help help for nerdctl
--host-gateway-ip string IP address that the special 'host-gateway' string in --add-host resolves to. Defaults to the IP address of the host. It has no effect without setting --add-host [$NERDCTL_HOST_GATEWAY_IP]
--hosts-dir strings A directory that contains <HOST:PORT>/hosts.toml (containerd style) or <HOST:PORT>/{ca.cert, cert.pem, key.pem} (docker style) (default [/tmp/.config/containerd/certs.d,/tmp/.config/docker/certs.d])
--insecure-registry skips verifying HTTPS certs, and allows falling back to plain HTTP
--kube-hide-dupe Deduplicate images for Kubernetes with namespace k8s.io
--log-file string Append nerdctl's own log to this file, in addition to the standard error [$NERDCTL_LOG_FILE]
--namespace string containerd namespace, such as "moby" for Docker, "k8s.io" for Kubernetes [$CONTAINERD_NAMESPACE] (aliases: -n) (default "default")
--selinux-enabled Enable selinux support
--snapshotter string containerd snapshotter [$CONTAINERD_SNAPSHOTTER] (aliases: --storage-driver) (default "overlayfs")
--userns-remap host Support idmapping for creating and running containers. This options is only supported on linux. If host is passed, no idmapping is done. if a user name is passed, it does idmapping based on the uidmap and gidmap ranges specified in /etc/subuid and /etc/subgid respectively
