Hello All,
I have an issue with one stack when I try to compose up it after restarting the docker service itself.
In the compose file I have referenced an external network :
networks:
pihole_network:
name: br0
external: true
I used it on two services in order to fix the ip of both container.
Unfortunately, as soon as I restart the docker service, I can’t restart the containers because the network_id is not available anymore.
I made some research and I found this :
If I create the containers using docker compose :
- The HostConfig:network_mode is set with the networkid of the referenced network name at the time of the creation of the container.
- I restart the docker service
- Then the networkId has changed leading to a failure to start both containers. They are referencing the old network id. In order to solve It I need to update the stack and recreate both container.
If I create the containers using docker run (with --net=br0 and --ip=)
- The HostConfig:network_mode is set to br0
- I restart the docker service
- Both containers restart fine because they are referencing the network by its name not its ID which is subject to be change.
Is it a normal situation ?
Can I change something on my compose in order to solve this issue ?
Thanks for your help,
Best regards,
Damien T.
