Last week I was getting stickers from the Ubuntu booth during the Open Infrastructure Conference in Denver. I asked a sorta dumb question, since this was a so new to me. My very first Open Infra Conference (formerly OpenStack Summit). I was asking a lot of questions.
I saw a sticker for MicroK8s (Micro-KATES).
Me: What is that?
Person in Booth: Do you know what MiniKube is?
Person in Booth: It is like that, but from the Ubuntu Opinionated version.
Me: Ok, cool, my whole lab is Ubuntu, except when it isn’t. So I’ll try it out.
Ten minutes later? Kuberenetes is running on my Ubuntu 16.04 VM.
Go over to https://microk8s.io/ to get the full docs.
Want a quick lab?
snap install microk8s --classic microk8s.kubectl get nodes microk8s.kubectl get services
Done. What? What!
So this was slightly annoying to me to type microk8s.blah for everyhing. So alias that if you don’t already have kubectl. I didn’t, this was a fresh VM.
snap alias microk8s.kubectl kubectl
You can run this command to push the config into a file to be used elsewhere.
microk8s.kubectl config view --raw > $HOME/.kube/config
Want the Dashboard? Run this:
microk8s.enable dns dashboard
It took my 5 minutes to get to this point. Now I am like OK lets connect to some Pure FlashArrays.
First we need enable priveleged containers in MicroK8s. Add this line to the following 2 config files.
# kubelet config
sudo vim /var/snap/microk8s/current/args/kubelet
sudo vim /var/snap/microk8s/current/args/kube-apiserver
Restart services to pick up the new config:
sudo systemctl restart snap.microk8s.daemon-kubelet.service
sudo systemctl restart snap.microk8s.daemon-apiserver.service
Now you can install helm, and run the Pure Service Orchestrator Helm chart.
