How to Install Docker Compose on Ubuntu

Docker is the by-product of Fig. Docker is a tool that allows managing the deployment of Linux applications that work inside software containers. It became quite typical to run a Linux command that would function in complex containers without burdening the system application where it frequently turns into a tough job.

Docker Compose is an open source utility which came into existence after the Fig application as its better and refined version. In this tutorial, you will learn how to install Docker on Ubuntu 18.04.

Why do Users Install Docker on Ubuntu

Let’s do a quick rundown of the main benefits users experience when using Docker Compose.

Docker is adaptable allowing users to carry out continuous testing, deploy and check outcomes as many times as they want, with as many implications. It becomes a laboratory in itself where a user can experiment with new commands to fill in the container and make it functional in various tasks.

This utility also supports multi-cloud computing, which means it is adaptable to applications which use cloud computing for saving data on servers. Think of services like Microsoft Azure, Puppet, Ansible, OpenStack and others.

Segregation in an isolated environment is another core aspect of Docker Compose that attracts developers. In addition, docker works with OS sensitive mount points like /sys and /proc which are read-only mounts.

How to Install Docker on Ubuntu 18.04

Time to learn how to install docker on Ubuntu! Remember, that first you’ll need to access your VPS using SSH. If you’re having trouble check out our PuTTY tutorial.

1. Update Your OS

First, update your machine to the latest release using the following commands:

sudo apt-get update
sudo apt-get upgrade

2. Create a New Repository Protocol

Here we will create the new protocol over HTTPS. Enter the following command into the command line:

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

3. Import the Command with Curl

Now we have to import the command while using the correct GPG Key with the curl command. For that simply type in the following command:

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

With this you would need an additional command to add Docker APT repository. Do it with the following command:

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

4. Install the Community Edition

Docker is now enabled and we can install the community edition with the following commands:

sudo apt-get update
sudo apt-get install docker-ce

5. Verify the Installation

Lastly, verify that Docker Compose is successfully installed:

sudo systemctl status docker

6. (Optional) Check the Version of Docker

You can start working right now, but we recommend you check the version with the following command:

docker -v

That’s it, it’s that easy to install Docker on Ubuntu 18.04.

How to Uninstall the Docker

There are two ways depending upon the type of installation process:

If you installed Docker using the curl command as shown in this tutorial, you can delete it by removing its directory with the rm command:

sudo rm /usr/local/bin/docker-compose

If you installed Docker through the pip command:

Pip uninstall docker-compose

Wrapping Up

Docker is the most effective tool to execute Linux Commands, as it provides the flexibility to work in complex containers and revive commands for multiple functions, carrying them out smoothly.

Docker can recreate or remove containers if they have been previously changed or not required anymore.

Now the tedious job of complex container configuration is made easy and error-free, helping innovative applications to be built without multiple counter commands that can leave developers in a mess. We hope Docker Compose serves you well. See you in the next tutorial!
