- Create a new network
- Launch a MySQL container and add it to the network that was created
- Launch an Adminer container and add it to the network that was created
- Verify that the two containers can communicate together via the network
- Run
docker network create mysqlnet
on your terminal.
- This command will create a new network called
mysqlnet
.
- Run
docker network ls
on your terminal.
- Make sure the
mysqlnet
network is on the list.
- Run
docker run --name mysql-server -e MYSQL_ROOT_PASSWORD=hunter2 -d mysql:5.7.25
on your terminal.
- The
:5.7.25
specifies the version of the image we want to use.
- The
-e
option will set an environment variable on the container with the supplied key/value pair.
- Note how we don't expose a port here at all.
- Run
docker run --name adminer -p 8080:8080 adminer -d
on your terminal
- At this point, we should have adminer running at
http://localhost:8080/
, but nowhere it can connect to. We can verify this with docker ps
and by using a browser to check adminer works.
- Note that trying to login to the MySQL server via adminer using
db
as the server, root
as the user, and hunter2
as the password does not work at this point.
- Run
docker network connect --alias db mysqlnet mysql-server
.
- This will connect the container named
mysql-server
to the network named mysqlnet
with a network alias of db
.
- Other containers can use the network alias we define here to connect to the container as long as they belong to the same network.
- Run
docker network connect mysqlnet adminer
.
- Again here, we connect the adminer container to the same network as the mysql server. This time we don't care about the alias as the adminer is a client and not a server.
- We can use
docker network inspect mysqlnet
to check what containers have been connected to the network.
- Finally, using the server
db
, user root
, and password hunter2
, we should be able to log in to the MySQL server via adminer's web interface.
- Stop the containers and remove the network:
docker stop adminer mysql-server && docker network rm mysqlnet
$ docker network create mysqlnet
