Install Container Runtime on Edge Nodes¶

Before edge nodes connect to the system, it is necessary to configure the node environment, which includes installing a container runtime. This article describes how to install containerd, a container runtime recommended in kubernetes community.

Install containerd¶

To integrate an Edge node requires some CNI plugins, so it is recommended to directly install containerd with CNI plugins. The steps are as follows:

1. Download containerd installation package and upload it to the edge node. See download link and select the appropriate version of the installation package based on the operating system and CPU architecture of the edge node.

2. Unpack the installation package to the root directory.

   tar xvzf {installation_package_name} -C /
   

3. Generate the containerd configuration file.

   mkdir /etc/containerd
   containerd config default > /etc/containerd/config.toml
   

4. Start containerd.

   systemctl start containerd && systemctl enable containerd
   

5. Verify whether containerd is successfully installed and running.

   systemctl status containerd
   

Install the nerdctl tool (optional)¶

It is recommended to install the nerdctl command-line tool for easier container operation and debugging on the node. The steps are as follows:

1. Download the nerdctl installation package and upload it to the edge node. See download page.

   Note

   Please select the appropriate installation package based on the operating system and CPU architecture. Install nerdctl v1.7.0 or higher.

2. Unpack the installation package and copy the binary file to the /usr/local/bin directory.

   tar -zxvf nerdctl-1.7.6-linux-amd64.tar.gz
   cd nerdctl-1.7.6-linux-amd64
   cp nerdctl /usr/local/bin
   

3. Verify that containerd is successfully installed.

   Use the following command to check the nerdctl version. If it is displayed correctly, it indicates that nerdctl has been successfully installed.

   nerdctl version
