Docker

Run docker without Sudo

Rather than Sudo'ing this will allow docker commands to be run without envoking sudo

1. Create a docker user group sudo synogroup --add docker
2. Change the owner group of the docker.sock file sudo chown root:docker /var/run/docker.sock
3. Add your user to the new docker group sudo synogroup --member docker $USER

Create network for Traefik

docker network create --driver=macvlan \

 --gateway=192.168.0.254 --subnet=192.168.0.0/24 --ip-range=192.168.0.0/26 \
 
 -o parent=ovs_eth0 -o macvlan_mode=bridge vlan_home

Running OpenVPN

1. Install VPN Server from package manager
2. After an upgrade you may need to run docker-compose from ssh session.

If you ever get the ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such device especially after a system upgrade then run or schedule the following

#!/bin/sh

# Create the necessary file structure for /dev/net/tun
if ( [ ! -c /dev/net/tun ] ); then
  if ( [ ! -d /dev/net ] ); then
    mkdir -m 755 /dev/net
  fi
  mknod /dev/net/tun c 10 200
  chmod 0755 /dev/net/tun
fi

# Load the tun module if not already loaded
if ( !(lsmod | grep -q "^tun\s") ); then
  insmod /lib/modules/tun.ko
fi

Backup Pi's 🥧 to NFS share

I want to backup database and configuration files to my NAS.

Enable NFS on the Synology NAS

1. From the Synology web interface, Go to Control Panel > File Services > NFS

2. Check Enable NFS Service. Set Maximum NFS Protocol to NFSv4.1 and click Apply

Create Backup and share allow IP of Pi's

1. On Synology web interface, go to Control Panel > Shared Folder
2. Select the folder you want to share and click Edit Click NFS Permissions > Create
3. Enter a hostname or IP for the Raspberry Pi that will be accessing the folder.
4. Leave Privilege on Read / Write and leave other settings at default, and click Save.

Note the Mount path at the bottom of the folder edit page, then click Save again to save the folder settings.

Mount NFS Share on Pi's

1. From the terminal – install nfs if not already installed: sudo apt update && sudo apt install nfs-common

2. Create the mount directory – change the path as appropriate: sudo mkdir /mnt/backup

3. Test access – replace IP address/ hostname with your details sudo mount -t nfs -o proto=tcp,port=2049 192.168.XX.XX:/volume1/backup /mnt/backup

4. Create persistent mount (e.g. will be around after reboot) sudo nano /etc/fstab Add this line to the bottom, again replacing ip addresses / hostname and file paths as needed: 192.168.XX.XX:/volume1/backup /mnt/backup nfs defaults 0 0 Exit, save the file.

5. Test fstab by running mount -a and then ls /mnt/backup
