Stopping and starting an Nginx web server

Stop and start the Nginx web server in the Kubernetes cluster.

Taking Nginx web server out of service

From a Terminal session on the Kubernetes master, run the following command:

kubectl scale deploy fci-common-ui-nginx --replicas=0

Output is similar to the following:

deployment.extensions/fci-common-ui-nginx scaled

This command stops the Nginx web server and users cannot access FCI via the Nginx web server.

fci-common-ui-nginx-58d48d8f97-xxxxx is no longer displayed in the kubectl get pods command output.

From a Terminal session on the Kubernetes master, run the following command:

kubectl scale deploy fci-common-ui-nginx --replicas=1

Output is similar to the following:

deployment.extensions/fci-common-ui-nginx scaled

fci-common-ui-nginx-58d48d8f97-xxxxx is displayed again in kubectl get pods command output.
