Docker cluster access

To acces a service in a cluster

Connect to pod service

1. Change the k8s context to the cluster context

   gcloud container clusters get-credentials [cluster-name] --zone europe-west4 --project [GC project]

2. Set the port forward to the cluster

   kubectl port-forward pod/[POD_NAME] [PORT]

Connect to mongo

1. Change the k8s context to the cluster context

   gcloud container clusters get-credentials master_dev --zone europe-west4 --project openbanking-214714

2. Set the port forward to the cluster

   kubectl port-forward pod/mongo-mongodb-primary-0 27017
