## Tableau Notes.txt
When you use Action:Filter you are removing data from analysis before it is illustrated on the
visualisation, when you use Action:Highlight first all of the data is visualised, and only after that
the action is applied. This can lead to discrepancies in results.

                How Communication happens between Docker container microservices
              
          
    Linking Microservice1 and Microservice2 using environment variable:

 docker run -d -p 8100:8100 --env APP_ENV_HOST=http://micro1 --name=micro2 --link micro1 dockerhubimage/micro2:latest
Creating custom network and linking the microservices:

docker network create micro-network
docker run -d -p 8000:8000 --name=micro1 --network=micro-network dockerhubimage/micro2:latest

  
## Docker tips
> You cannot remove a docker image if there is one or more container associated with it
> You cannot remove a container if it is up and running (need to stop and remove)
