Lately, there’s a lot of interest on ChatGPT, and yes, it’s really impressive the way it processes the context to provide answers to the questions. To give it a try, and put into play the requirements for writing a Risu plugin, I wrote some of the requirements in a paragraph: I want to create a bash script for checking system status. The script should use return codes to indicate success, failure, information, error or skipped via the values stored in the variables $RC_OKAY, $RC_SKIPPED, $RC_ERROR, $RC_FAILED and $RC_INFO....

With podman we can setup containers for being used for non root users by performing some simple steps: Install required packages dnf -y install slirp4netns fuse-overlayfs crun podman shadow-utils Force the number of user namespaces (might be required on some environments): echo "user.max_user_namespaces=28633" > /etc/sysctl.d/userns.conf sysctl -p /etc/sysctl.d/userns.conf Delegate Allows to define which resources are available1: mkdir -p /etc/systemd/system/[email protected] cat << EOF > /etc/systemd/system/[email protected]/delegate.conf [Service] Delegate=cpu cpuset io memory pids EOF To verify it has been done correctly, logout and login with the user and execute:...

Following on the Using Kcli to prepare for OCM testing, we’re going to prepare KMM testing in Hub-Spoke approach. First we need to prepare our .docker/config.json with the contents of our OpenShift pull secret used with Kcli. mkdir -p ~/.docker/ cp openshift_pull.json ~/.docker/config.json Warning advisories Note Semi-scripted version available at automate.sh Warning We’re using pre-release bits of the software, that’s why we need to define a custom catalog for both the Hub and the Spokes....

RHEL9 by default uses read-only socket which is not usable by some tools like Kcli… to enable it use: systemctl enable --now libvirtd.socket libvirtd-ro.socket systemctl stop libvirtd.service systemctl enable --now virtproxyd.socket virtproxyd-ro.socket systemctl stop virtproxyd.service

Kcli allows to quickly interact with different virtualization platforms to build machines with some specific configurations, and via the use of plans it allows to automate most of the setup required to have an environment ready. In our case, let’s setup an environment to practice with Open Cluster Management but instead of using kind clusters, let’s use VM’s. Note We’ll require to setup an openshift_pull.json file for Kcli to consume when accessing the required resources for this to work....
