Objective: Mongo express when accessed through a browser requests the mongoDB pod (eg: create a new database via web browser)
It was created a MongoDB pod with an internal service (no external requests are allowed to the pod). A Mongo Express deployment that contains the info needed to access the DB through Env variables. MongoDB URL are needed and a DB Username and Password so it was created a Configmap with the DB Url and a Secret with DB Username and Password. Both were referenced in the deployment file of Mongo Express. Mongo Express needs to be accessed through a web browser so an external service was created too.
