Let's explore what we just created:
$ docker network inspect authnet
This prints out a large JSON object describing the network, and its attached containers, which we've looked at before. If all went well, we'll see there are now two containers attached to authnet where there'd previously been only one.
Let's go into the userauth container and poke around:
$ docker exec -it userauth bashroot@a29d833287bf:/userauth# ls node_modules user-server.mjs users-list.js package-lock.json users-add.js users-sequelize.mjs package.json users-delete.js sequelize-docker-mysql.yaml users-find.js
The /userauth directory is inside the container and is exactly the files placed in the container using the COPY command, plus the installed files ...
