In this guide you will learn:

  • How to install Docker ?
  • How to run Docker without root ?
  • How to search for a Docker image ?
  • How to install a Docker image ?
  • How to run a Docker image ?
  • How to monitor Docker with various commands ?


Steps for installing Docker on Manjaro Linux

1. Perform System Update

To begin, we will update our Manjaro machine by running the following command:

$ sudo pacman -Syu


2. Install Docker

Here, we will install Docker by executing the below command:

$ sudo pacman -S docker


3. Start the Docker service

Once Docker is successfully installed, start the Docker service using the following command:

$ sudo systemctl start docker.service


4. Enable the Docker service

Next, we will enable the Docker service by running the following command:

$ sudo systemctl enable docker.service


5. Check Docker version

To the check the version of the Docker you have installed, run the following command:

$ sudo docker version

With this command, you can also verify if the installation has been successful or not. If the terminal returns the version number in the output, that means the installation was successful.


6. Check Docker info

To see information on Docker, you can use the below-mentioned command. This will tell you how many containers are currently active. You will also see the configurations through this command:

$ sudo docker info


7. Run Docker without root

To run Docker as a current user, you can add your account to the docker group with the help of this command:

$ sudo usermod -aG docker $USER


8. Reboot the system

Now that you have added all the configurations, you need to reboot your system to update the changes with the following command:

$ reboot


9. Search for a Docker image on Manjaro Linux

Now that we have installed and configured Docker, we can download Docker images. To download a specific docker image, first of all, we will search for it using the command syntax mentioned below:

$ docker search [name]

The docker image we are looking for is Nginx, so we will execute:

$ docker search nginx

This command will return a list of all the Nginx Docker images that you can choose from to install.


10. Install Docker image

We have decided to go with the hello-world docker image. To install it, use the pull command like this:

$ docker pull hello-world


11. Run a docker image

Once the image is downloaded, execute the following command to run it:

$ docker run hello-world


12. Monitor Docker

Docker allows us to monitor our images, the system resources being utilized by the image etc. This can be done by using the following command:

$ docker container ls


13. See installed Docker images

You can also check the list of all the installed Docker images through this command:

$ docker images


14. See statistics of running images

To see the system resources statistics (like RAM, CPU, and network usage) being utilized by the running images, issue this command:

$ docker stats


15. Docker's network configuration

You can also see Docker's network configurations with the help of the following command:

$ docker network ls
