Deploying with bash scripts

The following Kubernetes distributions are supported:

OpenShift (Fully Supported)
Google Kubernetes Engine (Partially Supported)

Requirements

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

Deploying GWS with OpenShift Platform

Copy your configuration to ~/.kube/config.
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.

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"

Working with Prometheus and Grafana

Important

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

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

Working with GWS Infrastructure

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

Working with GWS Application Stack

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

Pulling Current GWS Applications Container

- $ STACK_DOCKER_IMAGE_PATH=gws-registry-usw1.genhtcc.com ./pull-containers.sh

DNS Requirements

All of the services, either cluster-wide, infrastructure or GWS-applications ingresses require DNS names to be pre-populated to get access to and for host-based naming virtualization.

Openshift
GKE

    XX.XX.XX.XX   grafana.gke.local
    XX.XX.XX.XX   consul.gke.local
    XX.XX.XX.XX   active.gke.local
    XX.XX.XX.XX   test.gke.local

Persistent Storage Requirements

Openshift : the GlusterFS storage can be pre-populated manually.
GKE : No specific configuration is required.
No storage : Set the PERSISTENT_STORAGE=false in the environment file.
