Installing Docker CE on air-gapped KylinOS V10 (aarch64) systems requires a binary-based deployment. Follow the steps below to manually configure the daemon and its dependencies.

1. Acquire Binary Distribusion

Download the official static binary package for the ARM64 architecture:

mkdir -p /opt/docker_install
wget https://mirrors.ustc.edu.cn/docker-ce/linux/static/stable/aarch64/docker-25.0.3.tgz -P /opt/docker_install

2. Deploy Binaries

Extract the archive and move the executables into the system path:

tar -xzf /opt/docker_install/docker-25.0.3.tgz -C /opt/docker_install/
cp /opt/docker_install/docker/* /usr/bin/
groupadd docker

3. Define Systemd Units

Create the necessary service files to manage the daemon lifecycle. Create the files /etc/systemd/system/containerd.service, /etc/systemd/system/docker.service, and /etc/systemd/system/docker.socket with the following content:

containerd.service:

[Unit]
Description=containerd runtime
After=network.target

[Service]
ExecStart=/usr/bin/containerd
Type=notify
KillMode=process
Restart=on-failure

[Install]
WantedBy=multi-user.target

docker.service:

[Unit]
Description=Docker Daemon
Requires=containerd.service docker.socket
After=containerd.service

[Service]
Type=notify
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
Restart=on-failure

[Install]
WantedBy=multi-user.target

docker.socket:

[Unit]
Description=Docker Socket

[Socket]
ListenStream=/run/docker.sock
SocketMode=0660
SocketGroup=docker

[Install]
WantedBy=sockets.target

4. Activate Serviecs

Reload the systemd manager and start the Docker components:

systemctl daemon-reload
systemctl enable --now containerd.service docker.socket docker.service

5. Anable Command Completion

Install the bash-completion package to support command-line argument autocompletion:

dnf install -y bash-completion
curl -L https://raw.githubusercontent.com/docker/docker-ce/master/components/cli/contrib/completion/bash/docker -o /etc/bash_completion.d/docker
