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 172.17.0.1/16
  • Apstra same VM (in-place) upgrade docker network: inet 172.18.0.1/16

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

docker0

Update bip with the new subnet. If the /etc/docker/daemon.json file doesn't already exist, create one with the following format (Replace 172.26.0.1/16 in the example below with your own subnet.):

Docker Network and Apstra Upgrades

To use a different subnet, create or edit the /etc/docker/daemon.json file with the following format (Replace 172.27.0.0/16 in the example with your own subnet).
