Install Docker

Preparing Your Environment

• You will need to install docker and docker-compose.

• The following instructions assume Ubuntu 20.04 on an x86-64 CPU.

Install Docker

$ docker-compose --version

Test the installation:

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

Apply executable permissions to the binary:

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Download the current stable release of Docker Compose:

Install Docker Compose

$ sudo docker run hello-world

Test the installation:

$ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io

Install docker:

$ echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Setup the docker stable repository:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add Docker’s official GPG key:

 $ sudo apt-get update
 $ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

Update the apt package index and install packages to allow apt to use a repository over HTTPS:

$ sudo apt-get remove docker docker-engine docker.io containerd runc
