Install Docker on OpenSUSE

An essential reason for installing a docker is the handling and execution of containers. This brings as a main advantage that we can deploy applications without worrying about the dependencies or the system that runs it.

On the other hand, we will be able to create our own images of our applications and these will be able to be installed in any system with Docker.

OpenSUSE is a community operating system sponsored by SUSE. However, it is quite robust, reliable and secure and that is why it is used on many servers worldwide.

So let’s go for it.

First, open a terminal session and update the system.

:~$ sudo zypper up

This will cause all pending security patches to be installed and it is a good idea to do this before starting any installation.

Fortunately, Docker and Docker-compose are available from the official OpenSUSE repositories. While it is not the latest version, it is a fairly stable version that guarantees us functionality.

So run the following command:

:~$ sudo zypper in docker docker-compose

Accept the installation and then the process will begin.

Testing the installation

Once the installation has been successfully completed, the first thing to do is to start the Docker service.

:~$ sudo systemctl start docker

And then, you can check the status of the service to make sure it’s working properly.

:~$ sudo systemctl status docker

As you can see in the image, the service is running normally.

Also, if you want Docker to run as soon as the system starts, which is highly recommended, use this other command:

:~$ sudo systemctl enable docker

Now we can get a real example, check if Docker is ready for the job or not.

To do this we will use a test image that Docker puts at our disposal. You can execute it with the following command:

:~$ sudo docker run --rm hello-world

As you see in the image above. Docker’s installation has been successful.

To verify the current version of Docker, run the following command:

:~$ sudo docker version

However, if you want to use Docker without root privileges, just use the following command:

:~$ sudo usermod -aG docker $(whoami)

After that reboot the system and that is it. Docker is ready for the work.

Conclusion

Docker’s technology is a wonder if you work with large-scale servers. Its practicality when depleting applications makes it an alternative to virtual machines. And now you have learned to install it on OpenSUSE 15.2 / OpenSUSE 15.1.

So, you can also learn how to install Docker on other systems.

Alright, it’s time for installing the newest system into our PC. Here’s the step by step guide you’ll have to follow.

Prerequisites

At first, you need an installation media. The OS is available as an image file from the website. Grab the latest one. According to my download, it was nearly 4GB. After you’ve downloaded the ISO, it’s time to prepare a bootable USB flash drive.

Now, boot the USB flash drive in your system.

Installing openSUSE 15

• From the options, select “Installation”.

• After some time, the step of choosing the keyboard layout and accepting license agreement will appear. Select the options according to your need.

• After the installer completes initialization, you have the option of choosing the desktop environment. Interestingly, there’re also server options. However, for users, only GNOME and KDE Plasma are available as options. I choose to go with GNOME.

• From the same window, there appears a repository choosing option. Generally, you don’t have to do anything as everything is switched for the best scenario. However, if you’re an advanced user, subscribe to other repositories.

• Adding repositories is in the process. Wait for a few minutes here.

• Time for partitioning! Here, you have to exercise caution so that you don’t delete any important partition that contains data. For custom partitioning wizards, I recommend 16-20GB space for the “root” partition and 2-4GB for the “swap” area.

• Enter your username and password.

• Now, review the installation summary before proceeding the final markdown.

• The installation will be ongoing.

After the installation process is complete, you have to restart your system. Enjoy the awesome & brand-new openSUSE 15!

Close alignment with SLE

SUSE Linux Enterprise is one of the major factors for users. Generally, the previous systems were different than the professional edition, making it a difficult switch to the better one. Thanks to the devs, this openSUSE Leap 15 features all the improvements so that it’s now more aligned with the SLE version.

For the closer look, devs also changed the number to 15, despite the previous one was 42. The current version of the SUSE Linux Enterprise is 15. OpenSUSE 15 is going to get minor updates for the next 3 years.

New desktop environments

In the recent switch to the new openSUSE, it integrates the support for the newer release of GNOME (v3.26) and KDE Plasma (v5.12) desktops. For the GNOME desktop, Wayland is the default display server. It’s good to see that Wayland is getting into the center stage of all the Linux platforms.

New Installer, partitioning, and other tools

Switching to openSUSE 15, there are lots of improvements to the installer – YaST. For example, there’s a rework in the Libstorage-ng subsystem for more reliability and ease of usage. Here’s also a better switch from SuSEfirewall2 to the more popular Firewalld.

Other changes

• Linux kernel 4.12
• PHP 7
• GCC 7
• Cloud services support (NextCloud etc.)
• Atomic updates by Kubic

Here’s the complete list of all the new features and changes of openSUSE 15.
