Existing Docker Swarm Network with invalid subnet config is not upgraded gracefully when upgrading to 25.x #47331
Description
Description
We have clusters that have a manually created ingress network created with a subnet 10.0.0.1/16. While this is not a valid subnet block, we never had any issues with it.
Starting with #46183 it seems like validation upon container creation was improved. This however inadvertently caused our clusters to break upon upgrade.
I know the proper fix would be to recreate the ingress with 10.0.0.0/16, but that might not be the best course of action for production clusters.
Reproduce
- Create Cluster on Docker 24.x
- Remove ingress network
docker network rm ingress - Create ingress network with broken subnet range
docker network create --driver overlay --ingress ingress --subnet=10.0.0.1/16 - Create service using the network
- Upgrade cluster to 25.x
- see that service is not being brought up anymore
Expected behavior
Existing (overlay) networks should not stop working when upgrading Docker
