Deploying GWS

Implementation Steps

Unpack installation package (Example: IP_HTCCDev_9000197b1_ENU_dockerlinux.zip file) and navigate to "ip" folder which should contain following files: gws-microservices.tgz exported microservices in tar.gz format (e.g. gws-platform-configuration_9.0.000.42.tar.gz) Unpack gws-microservices.tgz archive to /opt/genesys/gws directory.

mkdir -p /opt/genesys/gws
tar xvf gws-microservices.tgz -C /opt/genesys/gws

Populate the Docker images (presented in *.tar.gz format) from installation package to your corporate docker registry.

for i in *.tar.gz; do /opt/genesys/gws/kubernetes/bin/push-containers-to-local-registry.sh $i %corporate_registry_address% --push; done

Important

This script must be run with Docker capable privileges and you must login to your registry before pushing.
