JDG Cross Site Replication Openshift

To use the ansible playbook you need to configure variables:

• site1_base_url: namespace . cluster domain
• site2_base_url: namespace . cluster domain
• quarkus_app: Name of the Quarkus Application. Default: jdg-employee-quarkus
• dotnet_app: Name of the Net Core Application. Default: jdg-employee-dotnet
• golang_app: Name of the Golang Application. Default: jdg-employee-golang

To test local download infinispan server from https://infinispan.org/download/

Openshift

Create cluster infrastructure

oc login --token=...
oc create namespace rhdg-xsite
oc project rhdg-xsite
oc create secret -n rhdg-xsite generic --from-file=identities.yaml dg-identities-secret
cd certs
./generate-certificate.sh
oc -n rhdg-xsite create secret generic xsite-keystore "--from-file=keystore.p12=$(pwd)/dg-keystore.p12" "--from-literal=password=secret" "--from-literal=type=pkcs12"
oc -n rhdg-xsite create secret generic xsite-truststore "--from-file=truststore.p12=$(pwd)/ca-keystore.p12" "--from-literal=password=caSecret"

oc delete secret -n datagrid dg-identities-secret --ignore-not-found
oc create secret -n datagrid generic --from-file=identities.yaml dg-identities-secret

Port-Forward datagrid

oc port-forward $(oc get pods -l app=infinispan-pod -o=custom-columns=NAME:.metadata.name --no-headers) 11222:11222
