Firebird/Developer Guidelines

Kubernete Dashboard

You can create a SSH tunnel and use port forward

ssh -L 8443:localhost:8443 beta-k8s-admin
k port-forward service/kubernetes-dashboard -n kube-system 8443:443

Test Environment

During development, it is very time consuming to rebuild docker image for streaming application and firebird web console. Here is what I did

Here is what you can do (1) Update firebird console code (2) run bin/dev-upload.sh (3) On firebird console, run ./dev_install.sh to pick up the change

To reload firebird web console

k rollout restart deployment/firebird-console-deployment

ZooKeeper

There might be time data in zookeeper might be corrupted, and sometimes it need manual recover.

Find ZooKeeper pod

k get pods
NAME                                           READY   STATUS    RESTARTS   AGE
demo-pod                                       1/1     Running   0          10h

zookeeper-7967d6f86-gjsrc                      1/1     Running   0          6h16m

k exec -it zookeeper-7967d6f86-gjsrc  -- bash
bin/zkCli.sh

# list everything under root
ls -R /

# delete everything under pipeline
deleteall /pipelines
delete /firebird-global-lock

Scale

kubectl scale --replicas=2 deployment/firebird-pipeline--test
