Deploying Web Services and Applications

After you install Docker and Kubernetes, follow the steps on this page to deploy Web Services and Applications.

Important

XR: Where and how to get the Docker image for deployment?

The following Kubernetes distributions are supported:

• OpenShift
• Google Kubernetes Engine

Requirements

1. Kubectl and Helm client utilities
   • Tiller is not required.
   1. For Google Kubernetes Engine deployments, install and configure the gcloud utility.
2. The scripts reside in the gws-microservices hg repository.

Deploying GWS with OpenShift Platform

• Copy your configuration to ~/.kube/config.
• Open a shell session.
• Type kubectl get nodes to list the nodes in your cluster.
• Type cd gws-microservices/production/premise/kubernetes to go to the kubernetes directory.
• Create your own environment configuration file and put it to env-examples directory. Or use the ones available.
  • Type . env-examples/<YOUR ENVIRONMENT SOURCE FILE> to source the cluster environment variables.
• Import GWS-applications docker images to your container registry or add the GWS registry keys to /etc/docker.d.
  • Get the registry keys and add them to /etc/docker.d on all hosts.
• Restart docker.

Deploying GWS with Google Kubernetes Engine

• Follow the registration web-UI steps.
• Open a shell session.
• Type gcloud container clusters list to list existing clusters for running containers.
• Type cd gws-microservices/production/premise/kubernetes to go to the kubernetes directory.
• Create your own environment configuration file and put it to "env-examples" directory. Or use the ones available.
• Type . env-examples/<YOUR ENVIRONMENT SOURCE FILE> to source the cluster environment variables.
  • Import GWS-applications docker images to your container registry or add the GWS registry keys to /etc/docker.d.
• Get the GWS-microservices docker images tarball via any Genesys supply channel and import it to Google Container Registry: TARBALL=/full/path/to/GWS/apps/tarball push-containers-to-gke.sh

Important

XR: Is there a sequence to be followed? What needs to be deployed first?

Deploying GWS Infrastructure

XR: Should we delete first before deploying?

./gws-infra-deploy.sh delete 
./gws-infra-deploy.sh

Deploying GWS Application Stack

./gws-app-deploy.sh delete
./gws-app-deploy.sh

Deploying Prometheus and Grafana

Important

These services are deployed cluster-wide and do not depend on GWS-applications' loads.

$ ./monitoring-deploy.sh delete
$ ./monitoring-deploy.sh
