- First, update your existing list of packages:
sudo apt update
- Next, install a few prerequisite packages which let apt use packages over HTTPS:
sudo apt install apt-transport-https ca-certificates curl software-properties-common
- Then add the GPG key for the official Docker repository to your system:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
- Add the Docker repository to APT sources:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
- Next, update the package database with the Docker packages from the newly added repo:
sudo apt update
- Make sure you are about to install from the Docker repo instead of the default Ubuntu repo:
apt-cache policy docker-ce
You’ll see output like this, although the version number for Docker may be different:
docker-ce:
Installed: (none)
Candidate: 18.03.1~ce~3-0~ubuntu
Version table:
18.03.1~ce~3-0~ubuntu 500
500 https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages
- Finally, install Docker:
sudo apt install docker-ce
- Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it’s running:
sudo systemctl status docker
- Run this command to download the current stable release of Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
- Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
- Note: If the command docker-compose fails after installation, check your path. You can also create a symbolic link to /usr/bin or any other directory in your path. For example:
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
- Test the installation.
docker-compose --version
