Add Docker Capabilities to TrueNAS Core

blog-image

Go into your TrueNAS and go to the virtual machine menu

Click Add to add a new virtual machine

You want these settings:

  • Guest operating system: Linux
  • Name: UBUDocker (or whatever you want it to be)
  • System Clock: Local
  • Boot method: UEFI
  • Shutdown time: 90
  • Start on boot enabled
  • Enable VNC enabled

Click next to dedicate resources to the VM

Here is how I have it setup, you can change it to your needs

Hit next to go to disk setup

You want to create a new disk, here are the settings you should use

Disk Type: AHCI

Zvol location: tank/vm

Size: Atleast 30 gigs

Hit next to go to network interface

The defaults are fine but make sure you select the right network adapter

Hit next to go to installation

Navigate to your ubuntu ISO file

Hit next, then submit, you have made the virtual machine!

Open the virtual machine then hit VNC to open ubuntu

Once its up choose your language and go through the installer

Once you are done with the setup we want to SSH into the ubuntu VM to setup docker

Open powershell and type SSH (ip)

See screenshot for example

Enter the username and password and close the VNC console

Go back into the console and get ready to type some commands

Type these commands in order

sudo apt update

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Type Y

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

sudo apt update

apt-cache policy docker-ce

sudo apt install docker-ce

To make it so you don’t have to use sudo for every docker command run this command

sudo usermod -aG docker ${USER}

su - ${USER}
