Docker doesn’t do anything to support these env vars. You’ll see many apps (including the MySQL image and the todo app)Īlso support env vars with a _FILE suffix to point to a file containing the variable.Īs an example, setting the MYSQL_PASSWORD_FILE var will cause the app to use the contents of the referenced fileĪs the connection password. These secrets are mounted as files in the running container. Diogo Monica, a former lead of security at Docker,Ī more secure mechanism is to use the secret support provided by your container orchestration framework. While using env vars to set connection settings is generally accepted for development, it’s highly discouraged MYSQL_DB - the database to use once connected.

The todo app supports the setting of a few environment variables to specify MySQL connection settings. What this means is that your app only simply needs to connect to a host named mysql and it’ll talk to the While mysql isn’t normally a valid hostname,ĭocker was able to resolve it to the IP address of the container that had that network alias. (your IP address will most likely have a different value). In the “ANSWER SECTION”, you will see an A record for mysql that resolves to 172.23.0.2 flags: qr rd ra QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 >HEADER<<- opcode: QUERY, status: NOERROR, id: 32162 In the following steps, you’ll create the network first and then attach the MySQL container at startup. Connect an already running container to a network.Assign the network when starting the container.There are two ways to put a container on a network: If you place the two containers on the same network, they can talk to each other. So, how do you allow one container to talk to another? The answer is Remember that containers, by default, run in isolation and don’t know anything about other processes So, like the following diagram, it’s best to run your app in multiple containers. Running multiple processes will require a process manager (the container only starts one process), which adds complexity to container startup/shutdown.Īnd there are more reasons.You don’t want to ship your database engine with your app then. While you may use a container for the database locally, you may want to use a managed serviceįor the database in production.

There’s a good chance you’d have to scale APIs and front-ends differently than databases.The following are a few reasons to run the container separately:

The following question often arises - “Where will MySQL run? Install it in the sameĬontainer or run it separately?” In general, each container should do one thing and do it well. But, now you will add MySQL to theĪpplication stack. Up to this point, you’ve been working with single container apps.
