A sample application suite for elastic community 2022 conference talk Elastic and kubernetes on your dev machine in 7 minutes
- Docker for Desktop with kubernetes enabled (this comes with kubectl and kustomize)
- Skaffold
- Helm
You willl also need the ability to run software as a privileged user.
- If you have already created a local-elastic-stack then skip this step. Install nginx ingress using helm quickstart.
kubectl create namespace ingress-nginx;
kubectl create secret tls nginx-tls-secret --key server.key --cert server.crt -n ingress-nginx;
helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx --namespace ingress-nginx --create-namespace --set controller.config.compute-full-forwarded-for='"true"' --set controller.config.use-forwarded-headers='"true"' --set controller.extraArgs.default-ssl-certificate=ingress-nginx/nginx-tls-secret;
- It is best to delete a previously create postgres persistent volume claim
kubectl delete pvc data-eccpg-postgresql-0 - Install a fresh postgres on k8s
helm install eccpg oci://registry-1.docker.io/bitnamicharts/postgresql --set auth.username=eccpg_user --set auth.password=eccpg_password --set auth.database=eccpg - Install a redis cluster
helm install eccredis oci://registry-1.docker.io/bitnamicharts/redis
- Go to the folders of eccfe, eccnodejs and eccjava in seperate terminals and run
skaffold dev - Browse to eccfe and do some actions. Then see the results in kibana
- Use some sort of migration scripts for the database
- Make sure logging for things like redis can be changed on the fly or at least easily upon new compilation
- Make sure that the application work without explicit deps where possible. i.e. the k8s should start if some thing is not available and try to connect again at later stage
- Update to latest version of elastic stack
