(Optional) Deploying the Containerd Environment

In addition to the Docker container runtime, the video stream cloud phone also supports the containerd runtime. If you choose to run the video stream cloud phone with containerd, refer to this section to deploy containerd-related software packages.

Obtaining Software Packages

Table 1 lists the software packages required for deploying the containerd environment.

**Table 1** Containerd-related software packages
Software	Version	Description	How to Obtain
Containerd	v1.7.14	A container runtime.	Containerd binary software package: containerd-1.7.14-linux-arm64.tar.gz Containerd service file: click here
runC	v1.1.12	runC is a lightweight container runtime that complies with the Open Container Initiative (OCI). It is a dependency component of containerd.	Download link
CNI plugin	v1.4.1	The Container Network Interface (CNI) is a specification and libraries for configuring network interfaces in Linux containers.	Download link
nerdctl	v1.7.5	nerdctl is a Docker-compatible CLI for managing containerd-based containers and images.	Download link

Deploying the Containerd Environment

Download and decompress the containerd binary package to the /usr/local directory.

mkdir -p /root/containerdenv/downloads
cd /root/containerdenv/downloads
wget https://github.com/containerd/containerd/releases/download/v1.7.14/containerd-1.7.14-linux-arm64.tar.gz --no-check-certificate
tar Cxzvf /usr/local containerd-1.7.14-linux-arm64.tar.gz

Check that the containerd version is v1.7.14.

1	containerd --version

Download the containerd service file and configure it as a system service.

cd /root/containerdenv/downloads
wget https://raw.githubusercontent.com/containerd/containerd/main/containerd.service --no-check-certificate
mkdir -p /usr/local/lib/systemd/system/
cp containerd.service /usr/local/lib/systemd/system/
systemctl daemon-reload
systemctl enable --now containerd

Check whether the containerd service is started.

1	systemctl status containerd

If the command output shown in the preceding figure is displayed, the containerd service has been started.

Download and install runC.

cd /root/containerdenv/downloads
wget https://github.com/opencontainers/runc/releases/download/v1.1.12/runc.arm64 --no-check-certificate
install -m 755 runc.arm64 /usr/local/sbin/runc

Check that the runC version is 1.1.12.

1	runc --version

Download and install the CNI plugin.

cd /root/containerdenv/downloads
mkdir -p /opt/cni/bin
wget https://github.com/containernetworking/plugins/releases/download/v1.4.1/cni-plugins-linux-arm64-v1.4.1.tgz --no-check-certificate
tar Cxzvf /opt/cni/bin cni-plugins-linux-arm64-v1.4.1.tgz

Download and install nerdctl.

cd /root/containerdenv/downloads
wget https://github.com/containerd/nerdctl/releases/download/v1.7.5/nerdctl-1.7.5-linux-arm64.tar.gz --no-check-certificate
tar Cxzvf /usr/local/bin nerdctl-1.7.5-linux-arm64.tar.gz

Check that the nerdctl version is 1.7.5.

1	nerdctl --version

Restart the Docker service and start a new terminal for the new container runtime to take effect.
1
systemctl restart docker
To switch to the Docker container runtime, remove the software binaries installed in 1 to 5 from the corresponding directories. After the removal is complete, run the preceding command to restart the Docker service and start a new terminal.
