Connect to other Docker container

Other Docker container can either be accessed by connecting back to the host os or by adding its image directly to the Devilbox stack.

Any Docker container on host os

To connect to any other Docker container on your host os from within the Devilbox Docker container, you first need to make sure, you are able to connect to your host os from within the Devilbox Docker container.

Once you are able to connect to the host os, start any other Docker container and make its port that you want to access available to your host os by specifying -p. An example with e.g. an external docker image grafana container might look like this:
Terminal window
```
host> docker run -d --name=grafana -p 3000:3000 grafana/grafana
```
You can then connect to your host os on port 3000 from within the Devilbox Docker container and be able to use it.

Add Docker container to Devilbox network

The Devilbox defines its own bridge network, usually called devilbox-app-net.

[!NOTE] The name may vary depending on the name of the Devilbox directory. It assembles itself by <Devilbox_dir_name>_app_net.

Start the Devilbox
Start your container of choice
Terminal window
```
host> docker run -d --name mycontainer
```

Attach your container to the Devilbox network

host> docker network connect devilbox_app_net mycontainer

Once you have done that, mycontainer is then part of the internal Devilbox network and is able to resolve Devilbox container by its name and vice-versa.

Connect from Devilbox PHP container to mycontainer

From inside the PHP container, you can then refer to your container by its hostname mycontainer

Add Docker container to Devilbox stack

Alternatively you can also add any Docker container to the Devilbox network by adding an image it to the Devilbox stack directly.
