Node Project

For Running The web app locally:

$  mv  /local/node  ~./home          //move node app to home directory because db setup at home for time to time restart.
$ npm install
$ node app.js 

Docker file and Dockerhub

For Running web App in Docker 

$ cd Node_Project or cd local/node    //Node_project - Production | local/node - local run

$ docker build   -t  dockerhub-username/node-project .

$ docker images  -a     //check for build image

$ docker push username/repository:tag

$ docker-compose up --build  

$ Open --->  localhost:3000
 

Getting Started With Kubernetes

For Running WebApp Clusters and Monitoring with Prometheus and Grafana

• Download cluster Config file from owner of cluster and connect to the cluster:

 $ cd ~/.kube && kubectl --kubeconfig="clustername-kubeconfig.yaml" get nodes

• Get kubectl nodes:

$ kubect get nodes

• Get pods:

    $ kubectl get pods 

• Get Services :

$ kubectl get services

• Get Deployments:

$ kubectl get services

• See MongoDb pods

$ kubectl exec -it mongo-mongodb-replicaset-0 -- mongo -u tikam -p --authenticationDatabase admin

• Port Forward Grafans to monitor in localhost:

$ kubectl port-forward -n monitoring svc/doks-cluster-monitoring-grafana 8000:80

• Port Forward Prometheus to monitor in localhost:

$  kubectl port-forward -n monitoring svc/doks-cluster-monitoring-pr-prometheus  9090:9090

• listing running Services in the monitoring namespace:

    $ kubectl get svc -n monitoring

• Deploying Spekt8 :

$ kubectl apply -f spekt8-deployment.yaml

$ kubectl apply -f fabric8-rbac.yaml.

$ kubectl port-forward deployment/spekt8 3000:3000
