Almalinux

I’ve started to running more containers in my homelab with Podman, running inside AlamaLinux. Most of the times, things just worked. However today, I tried to setup similar containers on OpenSUSE Leap 15.16 host, and I came across an issue getting containers to communicate with one another. Well, spoiler alert, I found a solution, hence this blog post. TL;DR - install cni-plugin-dnsname package from cni-plugin-dnsname build service. (No package from the official OpenSUSE repo). ...

Recently, I decided to pick up learning Kubernetes again after completely being absent from this world for many years. In this post, I’ll document how to install Helm CLI on AlmaLinx 9. Helm is like a package manager for Kubernetes. Helm CLI can be installed on your local machine, it does not to be installed on the Kubenetes node. However, in order to interact with your Kubernetes cluster, you’ll need to also have kubectl command as well as properly configured it to interact with your Kubernetes cluster. ...

I already wrote a blog post on How to install AWS CLI on RockyLinux, where I shared how to leverage the RPM package from EPEL repository. So what do I need to create a post here? Well, when I tried to use the same method to install the AWS CLI on an AlmaLinux 9.2, there was an issue with dependency. Here is what happened: [kenno@wedev1 ~]$ sudo dnf install awscli [sudo] password for kenno: Last metadata expiration check: 0:05:08 ago on Sun 20 Aug 2023 18:35:23. Error: Problem: conflicting requests - nothing provides python3.9dist(docutils) >= 0.10 needed by awscli-1.23.10-3.el9.noarch (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) Good thing is, there are a few ways to install AWS CLI on Linux. I’ll be using the method described at official AWS document to install the CLI. ...

A new post, a new problem, and a solution. Earlier today I worked on a task involving SSSD, System Security Services Daemon, a system service to access remote directories and authentication mechanisms. It got both excited and a little worried at the same times, since it’s been a long while since I had do anything with SSSD. Fast forward to the evening, I realized I had a FreeIPA server set up a long time ago right after passing the Red Hat Certified Specialist in Identity Management exam (EX362). Note this FreeIPA server was actually a second server I had set up after the EX362 exam. The original server was based on CentOS 7. The problem ...

I just setup a new server with a minimal installation of AlmaLinux 8. AlmaLinux is a variant of free Red Hat Enterprise Linux 8. It’s like a CentOS 8, but will have a full support until the end of RHEL 8 life cycle. This server is to serve as a new proxy for all VMs inside my home lab. I want to use tinyproxy which is need to be compiled from source as the RPM package is not available as of the time writing. After downloading the source code, and try to decompress it, I was presented with the following error message: ...
