#RaspberryPi #Docker #HomeServer
Running Docker containers on a Raspberry Pi? Cool! Running Docker containers off of an SD card and with low memory? Not cool! Let's see, what can we about speeding things up WITHOUT having to rebuild/reinstall your host.
Commands used in the video:
1) Storage creation:
ls -l /dev/disk/by-uuid/
mkfs.ext4 /dev/sda2
sudo mkdir /media/storage
sudo nano /etc/fstab
sudo reboot
sudo service docker stop
sudo mv /var/lib/docker /media/storage/
ln -s /media/storage/docker /var/lib/docker
sudo service docker start
docker stats
Template for extending /etc/fstab:
UUID=* /media/storage ext4 defaults,user,noatime,errors=remount-ro 0 2
2) Adding Swap / Virtual memory:
sudo swapoff -a
sudo dd if=/dev/zero of=/media/storage/swapfile bs=1G count=4
sudo mkswap /media/storage/swapfile
sudo swapon /media/storage/swapfile
