nerdctl: Docker-compatible CLI for containerd

nerdctl is a Docker-compatible CLI for containerd.

✅ Same UI/UX as docker

✅ Supports rootless mode

✅ Supports lazy-pulling (Stargz)

✅ Supports encrypted images (ocicrypt)

nerdctl is a non-core sub-project of containerd.

Examples

Basic usage

To run a container with the default CNI network (10.4.0.0/24):

# nerdctl run -it --rm alpine

To build an image using BuildKit:

# nerdctl build -t foo .
# nerdctl run -it --rm foo

Debugging Kubernetes

To list Kubernetes containers:

# nerdctl --namespace k8s.io ps -a

Rootless mode

To launch rootless containerd:

$ containerd-rootless-setuptool.sh install

To run a container with rootless containerd:

$ nerdctl run -d -p 8080:80 --name nginx nginx:alpine

See ./docs/rootless.md.

Install

Binaries are available for amd64, arm64, and arm-v7: https://github.com/containerd/nerdctl/releases

In addition to containerd, the following components should be installed (optional):

  • CNI plugins: for using nerdctl run.
  • CNI isolation plugin: for isolating bridge networks (nerdctl network create)
  • BuildKit: for using nerdctl build. BuildKit daemon (buildkitd) needs to be running.
  • RootlessKit and slirp4netns: for Rootless mode
    • RootlessKit needs to be v0.10.0 or later. v0.13.2 or later is recommended.
    • slirp4netns needs to be v0.4.0 or later. v1.1.7 or later is recommended.

These dependencies are included in nerdctl-full-<VERSION>-<OS>-<ARCH>.tar.gz, but not included in nerdctl-<VERSION>-<OS>-<ARCH>.tar.gz.

To run nerdctl inside Docker:

docker build -t nerdctl .
docker run -it --rm --privileged nerdctl

Motivation

The goal of nerdctl is to facilitate experimenting the cutting-edge features of containerd that are not present in Docker.

Such features includes, but not limited to, lazy-pulling and encryption of images.

Note that competing with Docker is not the goal of nerdctl. Those cutting-edge features are expected to be eventually available in Docker as well.

Also, nerdctl might be potentially useful for debugging Kubernetes clusters, but it is not the primary goal.

Features present in nerdctl but not present in Docker

Major:

Minor:

  • Namespacing: nerdctl --namespace=<NS> ps . (NOTE: All Kubernetes containers are in the k8s.io containerd namespace regardless to Kubernetes namespaces)
  • Exporting Docker/OCI dual-format archives: nerdctl save .
  • Importing OCI archives as well as Docker archives: nerdctl load .
  • Specifying a non-image rootfs: nerdctl run -it --rootfs <ROOTFS> /bin/sh . The CLI syntax conforms to Podman convention.

Trivial:

  • Inspecting raw OCI config: nerdctl container inspect --mode=native .

Similar tools

  • ctr: incompatible with Docker CLI, and not friendly to users. Notably, ctr lacks the equivalents of the following Docker CLI commands:

    • docker run -p <PORT>
    • docker run --restart=always --net=bridge
    • docker pull with ~/.docker/config.json and credential helper binaries such as docker-credential-ecr-login
    • docker logs

  • crictl: incompatible with Docker CLI, not friendly to users, and does not support non-CRI features

  • k3c v0.2 (abandoned): needs an extra daemon, and does not support non-CRI features

  • Rancher Kim (nee k3c v0.3): needs Kubernetes, and only focuses on image management commands such as kim build and kim push

  • PouchContainer (abandoned?): needs an extra daemon

Developer guide

nerdctl is a containerd non-core sub-project, licensed under the Apache 2.0 license. As a containerd non-core sub-project, you will find the:

information in our containerd/project repository.

Compiling nerdctl from source

Run make && sudo make install.

Using go get github.com/containerd/nerdctl is possible, but unrecommended because it does not fill version strings printed in nerdctl version

Test suite

Running test suite against nerdctl

Run go test -exec sudo -v ./... after make && sudo make install.

For testing rootless mode, -exec sudo is not needed.

To run tests in a container:

docker build -t test --target test .
docker run -t --rm --privileged test

Running test suite against Docker

Run go test -exec sudo -test.target=docker . to ensure that the test suite is compatible with Docker.
