How use it

1. install trino-operator

# install
> helm install trino-operator ./chart
# verify
> kubectl get -n trino-system deployments trino-controller-manager
NAMESPACE      NAME                       READY   UP-TO-DATE   AVAILABLE   AGE
trino-system   trino-controller-manager   1/1     1            1           72s

2. add crd resource config, the tarim_v1_trino.yaml e.g:

> kubectl apply -f config/samples/tarim_v1_trino.yaml
trino.tarim.deepexi.com/trino-sample created

> kubectl get trinos.tarim.deepexi.com trino-sample
NAME           TOTALCPU   TOTALMEMORY   COORDINATORNUM   WORKERNUM   PAUSE
trino-sample   3          3             1                2           false

>  kubectl get pods
NAME                                       READY   STATUS              RESTARTS   AGE
trino-sample-coordinator-9c9d4c79b-lmctw   0/1     ContainerCreating   0          51s
trino-sample-worker-5f57b75674-2w2qz       0/1     ContainerCreating   0          51s
trino-sample-worker-5f57b75674-rs25d       0/1     ContainerCreating   0          51s

> kubectl get svc
NAME                       TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
kubernetes                 ClusterIP   10.96.0.1        <none>        443/TCP          4h50m
trino-sample-nodeservice   NodePort    10.98.149.214    <none>        8080:31295/TCP   84s
trino-sample-trino         ClusterIP   10.109.139.133   <none>        8080/TCP         84s

when trino-sample-coordinator is ready,visit http://nodeIp:nodePort

see the coordinator and worker status in trino status

Release Note

version 0.1

• Basis function
• add a trino cluster in kubernetes
• edit crds to change config, restart the necessary parts
• add or delete worker when just change the num
• watch deployment and pod, logs trino coordinator and worker status in trinos status items

In next 0.2 version

• change deploy to stateful and add more settings
• add metrics, use prometheus or others
• fix TOTALCPU and TOTALMEMORY units
