PostgreSQL can be accessed via port 5432 on the following DNS names from within your cluster:

posgresql-postgresql.application-storage.svc.cluster.local - Read/Write connection

To get the password for "postgres" run:

export POSTGRES_PASSWORD=$(kubectl get secret --namespace application-storage posgresql-postgresql -o jsonpath="{.data.postgres-password}" | base64 --decode)

To connect to your database run the following command:

kubectl run posgresql-postgresql-client --rm --tty -i --restart='Never' --namespace application-storage --image docker.io/bitnami/postgresql:14.1.0-debian-10-r80 --env="PGPASSWORD=$POSTGRES_PASSWORD" \
  --command -- psql --host posgresql-postgresql -U postgres -d postgres -p 5432

To connect to your database from outside the cluster execute the following commands:

kubectl port-forward --namespace application-storage svc/posgresql-postgresql 5432:5432 &
PGPASSWORD="$POSTGRES_PASSWORD" psql --host 127.0.0.1 -U postgres -d postgres -p 5432

helm install redis bitnami/redis --namespace application-storage

Redis™ can be accessed on the following DNS names from within your cluster:

redis-master.application-storage.svc.cluster.local for read/write operations (port 6379)
redis-replicas.application-storage.svc.cluster.local for read-only operations (port 6379)

To get your password run:

export REDIS_PASSWORD=$(kubectl get secret --namespace application-storage redis -o jsonpath="{.data.redis-password}" | base64 --decode)

To connect to your Redis™ server:

1. Run a Redis™ pod that you can use as a client:

   kubectl run --namespace application-storage redis-client --restart='Never' --env REDIS_PASSWORD=$REDIS_PASSWORD --image docker.io/bitnami/redis:6.2.6-debian-10-r120 --command -- sleep infinity

   Use the following command to attach to the pod:

   kubectl exec --tty -i redis-client
   --namespace application-storage -- bash

2. Connect using the Redis™ CLI: REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h redis-master REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h redis-replicas

To connect to your database from outside the cluster execute the following commands:

kubectl port-forward --namespace application-storage svc/redis-master : &
REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h 127.0.0.1 -p
