Problem was wanting to save time and money on converting well-written C# code to Ubuntu. Solution was to use Mono and Visual Studio Code which allowed us to convert our application libraries straight across.

Hello guys

I am confused between choosing CentOS7 or centos8 for OpenStack tripleo undercloud deployment. Which one should I use? There is another option to use OpenStack, Ubuntu, or MicroStack.

We wanted to use this deployment to build our home cloud or private cloud infrastructure. I heard that centOS is always the best choice through a little research, but still not sure. As centos8 from Redhat is not supported for OpenStack tripleo deployments anymore, I had to upgrade to CentosStream.

While I'm not overly familiar with OpenStack I'd go with Ubuntu given that CentOS is being discontinued. Rocky Linux might be an option sometime in the future, which is a project started by the founder of the CentOS project.

I believe Canonical is going to be around and supporting the platform for at least the lifecycle of your system, whereas CentOS would mean that you are possibly going to be left unsupported after a certain date.

Personally, I haven't had a bad experience with either CentOS, or Ubuntu for the last 5 years, so the choice of distribution hasn't been overly significant and comes down to preference.

Cheers Dean

I've been providing software for the Navy that was intended to run on CentOS 7, which is the LTS (long-term support) version for several more years, with CentOS 8 having a lifespan ending this year. However, some companies (namely Microsoft) seem to be moving on from CentOS 7 to 8, at least with VS Code which dropped support for 7, in favor of 8, which leaves CentOS users in a horrible mess for shipping enterprise products. As a result, I've started moving to Ubuntu 20.04 LTS as the target environment, where possible. Support for Fedora 32 ended *today*. The Linux world is going through a bit of fast changes currently and I suspect the most stable place to be us Ubuntu 20.04 LTS, which will be supported into April 2030.

Hopefully Wayland will be an acceptable windowing system by 2030.

Openstack is made by Canonical, so if you're used to Ubuntu you'll feel right at home in some ways, but it's not so much an OS as it is a cloud management platform. You could use Ubuntu and OS together. As far as choosing an OS, that's really a matter of what you need as a person/company. I will say, I love ubuntu and always use the latest non-LTS versions just to check them out. They've recently took a weird turn away from Xorg and are now on Wayland.... If you need to screen share as a company, be mindful of this because as of right now, you may not be able to when using Wayland.

There is a question coming... I am using Oracle VirtualBox to spawn 3 Ubuntu Linux virtual machines (VM). VM1 is being used as a data lake - just a place to store flat files. VM2 hosts Apache NiFi. VM3 hosts PostgreSQL. I have built a NiFi pipeline that reads flat files on VM1 and then pipes the data over to and inserts it into the Postgresql database. I left this setup alone for a while, and then something hiccupped on VM3, and I had to rebuild it. Now I cannot make a remote connection to Postgresql on VM3. I was using pgAdmin3 on VM3, but it kept throwing errors - I found out it went end-of-life in 2018 and uninstalled it. pgAdmin4 is out, but for some reason, I cannot get the APT utility to find/install it. I am trying to figure out the pgAdmin4 install problem and looking for a good alternative for pgAdmin4 that I can use to diagnose the remote database connection problem. Does anyone have any suggestions? Thanks in advance.

phpPgAdmin

If you want an alternative to pgAdmin there is phpPgAdmin and it's also Open Source like pgAdmin, which is just like phpmyadmin which works for MariaDB and MySQL. I have not used it as I run pgAdmin4 in a Docker container.

Difference here is if you like to SQL edit, then pgAdmin is the best solution as it provides syntax highlighting whereas phpPgAdmin does not. Hope this is useful enough.

EDIT: Otherwise a good idea is to read on the differences between the two. Though I believe it as a personal preference.
