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....

In this post, I will create a new life-cycle environment paths for the Operations organization that includes life-cycle environments named Deveopment, QA, and Production. Let’s list the current life-cycle environment for Operations organization. [root@foreman ~]# hammer lifecycle-environment list --organization Operations ---|---------|------ ID | NAME | PRIOR ---|---------|------ 6 | Library | ---|---------|------ When we create our first environment, we’ll need to use the ID of the Library, which is 6 in this case....

In this blog post, I’m going to show how to add a new product caled EPEL8 and populate it with a repository from EPEL 8. There should be 3 main steps: Create a Content-Credentials which stores the package signing key of the product or repository Create a new Product Create a new Repository Firt thing first, let’s create a new content-credentials named RPM-GPG-KEY-EPEL-8 with the contents from the EPEL 8’s GPG signing key....

Let’s learn how to create an organization and location on Foreman/Satellite server using the hammer command-line-interface. In this example, I’m going to create an organization called: Operation and assign its location to Boston. On the Foreman server, excute the following commands: [root@foreman ~]# hammer organization create --name Operations Organization created. [root@foreman ~]# hammer location create --name Boston Location created. [root@foreman ~]# hammer organization add-location --name Operations \ > --location Boston The location has been associated....

When I setup Foreman (Satellite) server, I didn’t have Ansible support enabled. Here is how it can be done later on. If we only need Ansible support, it’s sufficient to just run this command: # foreman-installer \ --enable-foreman-plugin-ansible \ --enable-foreman-proxy-plugin-ansible Just a note for myself, I also need Remote Execution enabled if I want to run Ansible playbooks as Job Templates. # foreman-installer \ --enable-foreman-plugin-remote-execution \ --enable-foreman-proxy-plugin-remote-execution-ssh Note that the remote execution feature is enabled by default on Foreman/Satellite server....

One of my Red Hat servers is behind proxy with no access to the outside world. This box is registered to a Satellite server to receive software updates. I want to install Zabbix server on this server using the packages from Zabbix upstream directly. To do this, I need to set the proxy for the Zabbix’s repository. There are a few ways to do this. For my purpose, the best place is to set proxy=proxy_server directly in the ....
