# Docker with ZFS pool
|
|
|
|
When you already have working ZFS pool (see [here](/helios64/install/zfs)) and want to use Docker - it is good idea to use them togeter.
|
|
|
|
## **Step 1** - Prepare filesystem
|
|
|
|
```bash
|
|
sudo zfs create -o mountpoint=/var/lib/docker mypool/docker-root
|
|
sudo zfs create -o mountpoint=/var/lib/docker/volumes mypool/docker-volumes
|
|
sudo chmod 700 /var/lib/docker/volumes
|
|
```
|
|
|
|
Optional: If you use zfs-auto-snapshot, you might want to consider this:
|
|
|
|
```bash
|
|
sudo zfs set com.sun:auto-snapshot=false mypool/docker-root
|
|
sudo zfs set com.sun:auto-snapshot=true mypool/docker-volumes
|
|
```
|
|
|
|
Create `/etc/docker/daemon.json` with the following content:
|
|
|
|
```bash
|
|
{
|
|
"storage-driver": "zfs"
|
|
}
|
|
```
|
|
|
|
## **Step 2** - Install Docker
|
|
|
|
Add `/etc/apt/sources.list.d/docker.list` with the following content:
|
|
|
|
```bash
|
|
deb [arch=arm64] https://download.docker.com/linux/ubuntu focal stable
|
|
# deb-src [arch=arm64] https://download.docker.com/linux/ubuntu focal stable
|
|
```
|
|
|
|
Proceed with installation:
|
|
|
|
```bash
|
|
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
|
|
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
|
|
sudo apt update
|
|
sudo apt install docker-ce docker-ce-cli containerd.io
|
|
```
|
|
|
|
You might want this:
|
|
```bash
|
|
sudo usermod -aG docker your-user
|
|
```
|
|
|
|
Voila! Your Docker should be ready! Test it:
|
|
|
|
```bash
|
|
docker run hello-world
|
|
```
|
|
|
|
## **Step 3** - Optional: Install Portainer
|
|
|
|
```bash
|
|
sudo zfs create mypool/docker-volumes/portainer_data
|
|
# You might omit the above line if you do not want to have separate dataset for the docker volume (bad idea).
|
|
|
|
docker volume create portainer_data
|
|
docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce
|
|
```
|
|
|
|
Go to `http://yourip:9000` and configure.
