# 1. Install packages to allow apt to use a repository over HTTPS:
sudo apt-get update
sudo apt install ca-certificates curl gnupg lsb-release

# 2. Add Docker’s official GPG key:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \
  sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

# 3. add docker source
echo "deb [arch=$(dpkg --print-architecture) \
signed-by=/etc/apt/keyrings/docker.gpg] \
https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 4. Install docker
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io \
docker-buildx-plugin docker-compose-plugin

# 5. Setup permissions & logout then login.
sudo groupadd docker
sudo usermod -aG docker $USER

# docker image registry
docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
