minikube startup (pre eks)

minikube start --memory 4096 --cpus 4

Manual helm setup (pre terraform)

$ curl -LO https://git.io/get_helm.sh $ chmod 700 get_helm.sh $ ./get_helm.sh

Use RBAC to grant access to Tiller

kubectl create serviceaccount --namespace kube-system tiller kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller Then, finally

helm init --service-account tiller --upgrade

Manual chart installation (pre terraform, pre chart repository)

In helm/container1/

helm dependency update

Then, in root directory

helm install --name container1 ./helm/container1/ --set image.tag=latest,image.repository=lejeunen/container1

Check pod status and logs

Proxy local port 9000 to POD port 9000

kubectl port-forward container1-5f8bcc6c44-dmcvb 9000:9000

Deploy an updated image

We use the hash of the last git commit to tag the image, so that the new image is picked up by kubernetes. This follows the best practice to avoid "floating tags" such as latest.

See container1/deploy-last-commit.sh

traefik

helm install stable/traefik --name traefik --set dashboard.enabled=true,serviceType=NodePort,dashboard.domain=dashboard.traefik,rbac.enabled=true,service.nodePorts.http=30284 --namespace kube-system --tiller-namespace infra

kubectl port-forward --namespace kube-system traefik-8b7bdd879-fwvdk 8080:8080
