Configure Apstra Docker Subnets
date_range
03-Sep-24
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.):
content_copy zoom_out_map
$ sudo vi /etc/docker/daemon.json
{
"bip": "172.26.0.1/16"
}
$ sudo service docker restart
$ sudo service aos restartDocker 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).
content_copy zoom_out_map
$ sudo vi /etc/docker/daemon.json
{
"default-address-pools":
[
{
"base": "172.27.0.0/16",
"size": 24
}
]
}
$ sudo service docker restart
$ sudo service aos restart
