Raspberry Pi 4 arm64 + Docker + Portainer on USB3 storage

assume that /dev/sda1 is USB3 storage

Install docker and stop daemon

curl -sSL https://get.docker.com | sh
usermod -aG docker pi
service docker stop

Prepare external storage

mkfs.ext4 /dev/sda1
mkdir /mnt/external-storage
echo "/dev/sda1 /mnt/external-storage ext4 defaults,auto,users,rw,nofail,x-systemd.device-timeout=30 0 0" >> /etc/fstab
mount -a

Move docker workdir to external storage

rsync -avP /var/lib/docker /mnt/external-storage/
sudo rm -rf /var/lib/docker

cat > /etc/docker/daemon.json <<EOF
{
   "data-root": "/mnt/external-storage/docker"
}
EOF

service docker start

Run portainer

mkdir /mnt/external-storage/portainer-data

docker run -d \
  -p 9000:9000 \
  -p 8000:8000 \
  --name portainer \
  --restart always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /mnt/external-storage/portainer-data:/data \
  portainer/portainer-ce:alpine
