# Install Docker for Kata Containers on openSUSE Leap
|
|
|
|
> **Note:**
|
|
>
|
|
> - This guide assumes you have
|
|
> [already installed the Kata Containers packages](../opensuse-installation-guide.md).
|
|
>
|
|
> - If you do not want to copy or type all these instructions by hand, you can use the
|
|
> [`kata-manager`](https://github.com/kata-containers/tests/blob/master/cmd/kata-manager/kata-manager.sh)
|
|
> script to install the packaged system including your chosen container
|
|
> manager. Alternatively, you can generate a runnable shell script from
|
|
> individual documents using the
|
|
> [`kata-doc-to-script`](https://github.com/kata-containers/tests/blob/master/.ci/kata-doc-to-script.sh) script.
|
|
|
|
1. Install the latest version of Docker with the following commands:
|
|
|
|
> **Note:** This step is only required if Docker is not installed on the system.
|
|
|
|
```bash
|
|
$ sudo zypper -n install libcgroup1
|
|
$ sudo zypper -n install docker
|
|
```
|
|
|
|
For more information on installing Docker please refer to the
|
|
[Docker Guide](https://software.opensuse.org/package/docker).
|
|
|
|
2. Configure Docker to use Kata Containers by default with one of the following methods:
|
|
|
|
1. systemd
|
|
|
|
```bash
|
|
$ sudo mkdir -p /etc/systemd/system/docker.service.d/
|
|
$ cat <<EOF | sudo tee /etc/systemd/system/docker.service.d/kata-containers.conf
|
|
[Service]
|
|
ExecStart=
|
|
ExecStart=/usr/bin/dockerd -D --containerd /run/containerd/containerd.sock --add-runtime kata-runtime=/usr/bin/kata-runtime --default-runtime=kata-runtime
|
|
EOF
|
|
```
|
|
|
|
2. Docker `daemon.json`
|
|
|
|
Add the following definitions to `/etc/docker/daemon.json`:
|
|
|
|
```json
|
|
{
|
|
"default-runtime": "kata-runtime",
|
|
"runtimes": {
|
|
"kata-runtime": {
|
|
"path": "/usr/bin/kata-runtime"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
3. Restart the Docker systemd service with the following commands:
|
|
|
|
```bash
|
|
$ sudo systemctl daemon-reload
|
|
$ sudo systemctl restart docker
|
|
```
|
|
|
|
4. Run Kata Containers
|
|
|
|
You are now ready to run Kata Containers:
|
|
|
|
```bash
|
|
$ sudo docker run busybox uname -a
|
|
```
|
|
|
|
The previous command shows details of the kernel version running inside the
|
|
container, which is different to the host kernel version.
