EKS issues in files apply and 04-allow-cluster-to-access-rds.sh

In the file apply, the method `apply_template` is called on worker-service.yml and web-service.yml. These files don't exist in the project. 

In the file 04-allow-cluster-to-access-rds.sh in the code
 `kubectl run \
  -i \
  --restart=Never \
  --rm \
  --env PGPASSWORD="$POSTGRES_PASSWORD" \`
The environment variable PGPASSWORD does not exist, it should be POSTGRES_PASSWORD.
