Continuous Delivery with Docker and Jenkins

Changing the acceptance test stage

For the purpose of using docker-compose scale, we didn't specify the port number under which our web service would be published. If we did, then the scaling process would fail because all clones would try to publish under the same port number. On the contrary, we let Docker choose the port. Therefore, we need to change the acceptance_test.sh script to first find what the port number is and then run curl with the correct port number.

#!/bin/bashCALCULATOR_PORT=$(docker-compose port calculator 8080 | cut -d: -f2)test $(curl localhost:$CALCULATOR_PORT/sum?a=1\&b=2) -eq 3

Let's figure out how we found the port number:

1. The docker-compose port calculator 8080 command checks under which IP and port address the ...
