Run commands to install docker in an ubuntu machine
Docker Engine
// download the script
$ curl -fsSL get.docker.com -o get-docker.sh
// create permission
$ chmod +x get-docker.sh
//run the script
$ sh get-docker.sh
// check if it is successfully installed
$ docker --version
Docker Compose
Docker Compose helps us to running multi-container Docker applications with a YAML file configuration.
// download docker-compose
$ sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
// Apply docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose
// check if it is successfully installed
$ docker-compose --version
Docker Machine
Docker Machine lets us install Docker Engine on virtual hosts, and manage the hosts with docker-machine commands.
// install docker-machine
$ base=https://github.com/docker/machine/releases/download/v0.16.0 &&
curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker-machine &&
sudo mv /tmp/docker-machine /usr/local/bin/docker-machine &&
chmod +x /usr/local/bin/docker-machine
// check if it is successfully installed
$ docker-machine --version
note : adding our user to the “docker” group, so that we can use docker as a non-root user
$ sudo usermod -aG docker your-user
