Building Microservices with Go

Specifying a project name

As we discussed earlier when we start docker-compose, it will create services with the given names in your Compose file appending the project name default to them. If we need to run multiple instances of this compose file, then docker-compose will not start another instance as it will check to see if any services are running with the given names first. To override this, we can specify the project name replacing the default name of default. To do this we just need to specify the -p projectname argument to our command as follows:

$ docker-compose -p testproject up  

This will then create two containers:

• testproject_testserver
• testproject_curl
