Install Docker

These steps install Docker Community Edition (CE) using the official Ubuntu repositories. To install on another distribution, or to install on Mac or Windows, see the official installation page.

1. Remove any older installations of Docker that may be on your system:

sudo apt remove docker docker-engine docker.io

2. Make sure you have the necessary packages to allow the use of Docker’s repository:

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

3. Add Docker’s GPG key:

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

4. Add the stable Docker repository:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

5. Update your package index and install Docker CE:

sudo apt update
sudo apt install docker-ce

Install Docker Compose

1. Download the latest version of Docker Compose. Check the releases page and replace 1.25.4 in the command below with the version tagged as Latest release:

sudo curl -L https://github.com/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

2. Set file permissions:

sudo chmod +x /usr/local/bin/docker-compose
