Orignally posted at Red Hat Developers Java is one of the most used languages out there and has been in the top three for the last two decades. Java powers millions of applications across verticals and platforms. Linux is widely deployed in data centers, Edge networks, and Cloud. Today we announce the availability of Quarkus for all our Red Hat Enterprise Linux (RHEL) customers. If you are running RHEL, you can now also run Red Hat Build of Quarkus (RHBQ).

I use Fedora as my regular Linux. And I have been doing that for years now, even though I am a developer its simple and straight forward enough to get my way around. It has some great features and spins. You should check it out at Fedora project Here is a quick list of things that worked for me to setup docker on Fedora 33. I followed the guidelines here. Plus some more to config the firewall and user access.

Orignally posted at Red Hat Developers A Java runtime environment should be able to run compiled source code, whereas a development kit, for example, OpenJDK, would include all the libraries/binaries to compile and run the source code. Essentially the latter is a superset of the runtime environment. More details on OpenJDK support and lifecycle can be found here. Red Hat ships and supports container images with OpenJDK for both Java 8 and 11.

I have been using Linux for quite some time now, and jumping from windows xp to windows 10 was a huge change for me. Not just that I had completely forgotten what windows was all about, configs, screens, services. Anyways, I made a quick compilation of how you could run Fedora 23 and on VirtualBox running on windows 10. Software versions Windows: 10 VirtualBox: 5.0.16.x Fedora: 23 Sidetrack tip: Even though the installer was in English , it changed my language to Danish.

While running fedora, if you want to change the port for your ssh, just changing the firewall rules will not make a difference. If you are running selinux its important that you change the policy to allow a different port as well. I did learn it the hard way though, hopefully the following guide should be helpful. Lets start by an introduction to semanage. From man Description semanage is used to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources.
