gophercon 2018 demo
This repo contains all the software that is going to be used during the Gophercon 2018 demo of my talk.
A Kubernetes cluster somewhere. For example, if you want one on gcloud:
$ PROJECT_ID=gophercon-$RANDOM $ gcloud projects create $PROJECT_ID $ gcloud config set project $PROJECT_ID $ gcloud config set compute/zone europe-west1-b $ gcloud container clusters create gke # It will ask you to enable Kubernetes, do it
If you are cheap (like me) you can create a cluster of preemptible machines instead:
$ gcloud beta container clusters create gke-preemptible --preemptible $ gcloud config set container/cluster gke-preemptible $ gcloud beta container node-pools create preemptible-pool --preemptible $ gcloud beta container node-pools delete default-pool
Now you can get the credentials to start using your cluster:
$ gcloud container clusters get-credentials gke # or gke-preemptible
Helm on it. If you are having RBAC problems: https://github.com/kubernetes/helm/blob/master/docs/rbac.md
$ helm init
$ helm install -f hack/jenkins-values.yaml stable/jenkins
On Jenkins you will also need a "username and password" secret called:
agonzalezro-hub-credentials(or change the
Jenkinsfileif you want to use other ID) for having access to push images to Docker Hub.
If you want to use the In-Cluster Config for
kubectlwithout having to bother about permissions permissions you can give them all to the default account:
$ kubectl create -f hack/do-not-do-this-at-home-rbac.yaml
Come to the talk and you will see!
