Lesson Learned #19

Closed MichaelLeeHobbs closed 3 years ago

MichaelLeeHobbs commented 3 years ago

Been using Docker for years so I'm not exactly paying close attention. I've used kubespray and vagrant to build a cluster. While on episode 3 I wanted to be able to hit the hello app from my work station so I modified the expose command.

kubectl expose deployment hello-go --port=80 --target-port=8180 --type=NodePort --external-ip=192.168.1.171

192.168.1.171 being the IP of one of my two master nodes...

A.... few hours latter...

watch -n1 -x ip addr del 192.168.1.171/32 dev kube-ipvs0 <-- on each node

That continuously deletes the service ip from the ipvs interface give me time to run

kubectl delete service hello-go

Obviously, I could have just blown up the cluster and rebuilt it but I learned so much about how k8s works vs docker swarm.

Jeff as always keep up the good work! I started my DevOps journey many years ago with your book on Ansible.
