Tips

A few days ago I started to re-surrect my Foreman(/katello) server and wanted to use it to pull content from remote repository for AlmaLinux. This involves updating Foreman with a new product and related AlmaLinux repository. I wrote a similar post on creating product & repository using hammer before for EPEL 8. However, it’s been a long while and things could change with the current version of Foreman server. # rpm -qa | egrep -i '^foreman-[0-9]|^katello-[0-9]|^pulp-server-[0-9]' katello-4....

I’ve been running Fedora 34 pre-release version even before it became beta. Everything has been working so far until recently when a package dracut was updated from 0.58 to 0.58-1. What is dracut? Good question. It’s an initramfs infrastructure used on Fedora system. Find out more from Dracut. The issue that introduced in version 0.58-1 on F34 is that it prevents any machines that use LUKS encryption for root partition to boot....

On my Fedora 33 system, the systemd journal is persistently logged. Over time, the size of the log accumulate quite a lot. # du -shx journal/ 4.2G journal/ I already cleaned up the log twice in the past, but I already forgot how to do it. To fix my short-term memory, I’m going to document how I do this by following this blog post Clear systemd journal. The command for cleaning up old logs is journalctl with the option --vaccume-time=OLDER_THAN_TIME....

I have a need to setup a virtual network on a VM-host server. Usually, I just use the virt-manager gui application to create this task. However, I’d like to do this via command line this time. Why? Well, why not? It’s always fun to learn new thing. :) libvirt keeps network configuration in XML files under /etc/libvirt/qemu/networks/. Here is what I have on one of my machines: # ls -1 /etc/libvirt/qemu/networks/*xml /etc/libvirt/qemu/networks/classroom....

In this blog post, I’m going to practice publishing and promoting content views using the hammer CLI. I already know how to do this using the Satellite/Foreman web UI. First, I’m going to create the Base content view for Operations organization and Boston location. [root@foreman ~]# hammer content-view create \ > --name Base --organization Operations \ > --description 'Base Packages' Content view created. [root@foreman ~]# hammer content-view list --organization Operations ----------------|---------------------------|--------------------------|-----------|---------------------|--------------- CONTENT VIEW ID | NAME | LABEL | COMPOSITE | LAST PUBLISHED | REPOSITORY IDS ----------------|---------------------------|--------------------------|-----------|---------------------|--------------- 6 | Base | Base | false | | ----------------|---------------------------|--------------------------|-----------|---------------------|--------------- The next step is adding the repos to the content view....
