deploying jacamo-rest

Deploying cleberjamaral/jacamo-rest-run, available at docker hub.

Deploying

• Deploying cleberjamaral/jacamo-rest-run which is available in docker hub$ microk8s.kubectl create deployment jacamo-rest --image=cleberjamaral/jacamo-rest-run

• Get pod name $ export POD_NAME=$(microk8s.kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}')

Exposing ports

• Exposing $ microk8s.kubectl expose deployment/jacamo-rest --type="NodePort" --port 3271,3272,3273,8080

• Check IP provided for the jacamo-rest created service $ microk8s.kubectl get services

• Performing a simple test $ curl http://provided_IP:8080/overview

Forwarding connections

• port-forward option needs socat installed on the host.

• In theory, is seems a port forward of host to the service/deployment/pod should be a good solution but in the first tests it is not working yet. I have tried $ microk8s.kubectl port-forward deployment.apps/jacamo-rest 8080:8080

• However, what is working is directly through socat $ socat TCP-LISTEN:8080,fork,reuseaddr TCP:provided_IP:8080

Opening terminal

• Open terminal $ microk8s.kubectl exec -ti $POD_NAME -- bash

Troubleshooting

• Describe pod $ microk8s.kubectl describe pod/$POD_NAME

• Get logs $ microk8s.kubectl logs pod/$POD_NAME
