# Setting up Docker (and Docker Desktop) on Ubuntu ## Sources

• https://docs.docker.com/desktop/setup/install/linux/ubuntu/

## Prerequisites

1. verify you have a GNOME-based desktop environment (Ubuntu Desktop is GNOME-based)
   1. if not install gnome-terminal - `sudo apt install gnome-terminal`
2. verify you have KVM virtualization support - `lsmod | grep kvm`
   1. if `kvm` and `kvm_<arch>` is not listed check [here](https://docs.docker.com/desktop/setup/install/linux/#kvm-virtualization-support)
   2. ensure your user is part of the kvm group - `sudo usermod -aG kvm $USER`

## Install Steps

1. ensure apt-get is up to date - `sudo apt-get update`
2. download the proper install for docker-desktop
   1. for Ubuntu this is a `.deb` file
   2. https://download.docker.com/linux/ubuntu/dists/
      1. to make sense of the release names see https://wiki.ubuntu.com/Releases
      2. (24.04.2 LTS = “Noble Numbat” = https://download.docker.com/linux/ubuntu/dists/noble/pool/stable/)
      3. find the right directory for your CPU architecture via `dpkg –print-architecture`
         1. https://download.docker.com/linux/ubuntu/dists/noble/pool/stable/amd64/
      4. download the latest version of all install files
         • containerd.io_<version>_<arch>.deb
         • docker-buildx-plugin_<version>_<arch>.deb
         • docker-ce-cli_<version>_<arch>.deb
         • docker-ce-rootless-extras…?
           • not certain about this one; it's listed in the download site but not the docs
         • docker-ce_<version>_<arch>.deb
         • docker-compose-plugin_<version>_<arch>.deb
      5. install the packages
         1. `sudo dpkg -i ./containerd.io_*.deb ./docker-ce_*.deb ./docker-ce-cli_*.deb ./docker-buildx-plugin_*.deb ./docker-compose-plugin_*.deb`

## Startup and Verify Docker

1. `sudo service docker start`
2. verify with a hello-world container
   1. `sudo docker run hello-world`
3. configure to start on boot
   1. `sudo systemctl enable docker.service containerd.service`

## Configure Docker Logging

1. `vi /etc/docker/daemon.json`
   1. add logging config per https://docs.docker.com/engine/logging/drivers/json-file/#usage

## Install Docker Desktop

• get latest deb file (rather large - 356MB)
  • `curl -O https://desktop.docker.com/linux/main/amd64/docker-desktop-amd64.deb`
• `sudo apt-get install ./docker-desktop-amd64.deb`
  • ignore error msg at end (`N: Download is performed unsandboxed as root as file '…/docker-desktop-amd64.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)`
• there should now be a “Docker Desktop” icon in the Apps section
