+tags:

+---
+
+## The solution
+
+On a single node cluster, control plane nodes are tainted so that the cluster never schedules pods on them. To change that run :
+{{< highlight sh >}}
+kubectl taint nodes --all node-role.kubernetes.io/master-
+{{< /highlight >}}
+
+Getting dns in your pods :
+{{< highlight sh >}}
+add  --cluster-dns=10.96.0.10 to /etc/conf.d/kubelet
+{{< /highlight >}}

 ## Installation media
 
 You can get a bootable iso or liveusb from https://www.gentoo.org/downloads/. I recommend the minimal one. To create a bootable usb drive juste use `dd` to copy the image on it. Then boot on this brand new installation media.

 ## Partitionning

+## Introduction
+
+Now that I am mostly running OpenBSD servers I just use genkernel to build my custom configuration on each node with :
+{{< highlight sh >}}
+eselect kernel list
+eselect kernel set 1
+genkernel all  --kernel-config=/proc/config.gz --menuconfig
+nvim --diff /proc/config.gz /usr/src/linux/.config
+{{< / highlight >}}
+
+Bellow you will find how I did things previously when centralising the build of all kernels on a collab-jde machine, and distributing them all afterwards. Local nodes would only rebuild local modules and get on with their life.

+## Introduction
+
 I am not using a multilib profile on gentoo (I use amd64 only everywhere), so when the time came to install steam I had to get a little creative. Overall I believe this is the perfect
 way to install and use steam as it self contains it cleanly while not limiting the functionalities. In particular sound works, as does the hardware acceleration in games. I tried to
 achieve that with containers but didn't quite made it work as well as this chroot setup.
