Configuring the Docker network

In the Docker Network tab, you can edit the IP range of the docker0 interface of the Edge Device, if necessary.

The IP address of the docker0 interface is the start of the docker0 interface. By default, the docker0 interface starts with 172.17.0.0. By default, the Edge Device contains 2 Docker networks, 1 for the proxy-redirect and 1 for the docker0 interface (that you create in the IP Address input field). When you install an app which creates a new Docker network on the Edge Device, the Docker network of the installed app must not overlap the Docker networks of the Edge Device and need free Docker network IP ranges on the Edge Device. Otherwise, if you want to install an app that tries to create a new Docker network on the Edge Device but the Edge Device has no free Docker network IP ranges, the app installation fails.

You can just edit the IP range in a given range with a specific netmask to prevent errors in the system.

Procedure

  1. In the Settings screen, click the Docker Network tab.

  2. In the IP address input field, enter the IP address that you want to use for the docker0 network.
