Configure Apstra Docker Subnets

The Apstra server Docker containers require one network for internal connectivity, which is automatically configured with the following subnets:

  • docker0: inet
  • Apstra same VM (in-place) upgrade docker network: inet

If you need to use these subnets elsewhere, to avoid conflicts, change the Docker network as follows:


Update bip with the new subnet. If the /etc/docker/daemon.json file doesn't already exist, create one with the following format (Replace in the example below with your own subnet.):

To use a different subnet, create or edit the /etc/docker/daemon.json file with the following format (Replace in the example with your own subnet).
