# docker installation

This documentation shows how to install docker from the docker ppa
### Create users and groups
First create a user and group `cloud`
```bash
useradd -u 1002 -m cloud
```
Add the user `cloud` to the sudo group
```bash
usermod -a -G sudo cloud
```
Add a `docker` group
```bash
groupadd docker
```
Add the user `cloud` to the docker group
```bash
usermod -aG docker cloud
```
Gibe the user the bash shell
```bash
usermod --shell /bin/bash cloud
```
### basic dependencies
Ubuntu 22.04 LTS
```bash
# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
```
Ubuntu 24.04 LTS
```bash
apt install apt-transport-https curl
```
Install some basic dependencies
```bash
apt update && apt upgrade -y && apt install vim screen lsof apt-transport-https ca-certificates curl software-properties-common -y 
```
Ubuntu 20.04
```bash
sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
```
### docker repository configuration
Ubuntu 24.04 LTS
```bash
https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
```
```bash
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
```
```bash
apt update
```
Add the repository key of the docker repository
```bash
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
```
Now add the apt configuration for the repository
```bash
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
```
You could also alternatively add the `testing`repository instead of the `stable`repository
```bash
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) test"
```
### install docker
```bash
apt update && apt install docker-ce docker-ce-cli containerd.io -y
```
### install docker-compose
Get the latest docker-compose
```bash
curl -L  https://github.com/docker/compose/releases/download/v2.27.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
```
Set the proper rights
```bash
chmod +x /usr/local/bin/docker-compose
```
And check if `docker-compose` works
```bash
docker-compose --version
```
This should give a response like this
```bash
docker-compose version 1.25.0-rc2, build 661ac20e
```
