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 "$(uname -s)-$(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
Install docker:
$ echo \
"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Setup the docker stable repository:
$ curl -fsSL | 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 \
Update the apt package index and install packages to allow apt to use a repository over HTTPS:
$ sudo apt-get remove docker docker-engine containerd runc
