Containers of a docker stack not coming up after host reboot


(Naanuswaroop) #1

We need to deploy a docker stack in a CentOS VM. We have a docker compose file to launch a stack with two services and one container in each of the services. One of these containers connects to two external networks.

The docker-compose.yml looks like this:

version: ‘3’
image: postgres
image: sshweb_5:new
command: bash
- .:/code
- “8000:8000”
- “8022:22”
- external_oam_network
- external_data_network
- GoOn_db
name: goon__oam
name: goon__data

The external networks are swarm scoped macvlan networks created using below commands:

docker network create --config-only --subnet --gateway -o parent=eth1 --ip-range __goon__data
docker network create -d macvlan --scope swarm --config-from __goon__data goon__data

The docker stack is created using below command:

docker stack deploy --compose-file docker-compose.yml app

The Issue:

With the above configuration, docker stack comes up perfectly the first time. But, if the hosting VM goes for a reboot [or crashes and comes up again], the container that is connected to the external networks (GoOn_web service), fails to come up. Following are the errors seen in journallogs.

The other issue observed is that there is no way to clean up the network along with its config completely. The following commands were tried:

[localhost config_drive]# docker stack rm app
Removing service app_GoOn_db
Removing service app_GoOn_web
Removing network app_default
[localhost config_drive]# docker network rm goon__data
[localhost config_drive]# docker network rm __goon__data
Error response from daemon: configuration network “__goon__data” is in use

It seems like the network cleanup has some issue as well.
Please let us know if there are any workarounds for this issue or if our configuration needs some tweaking.

The following are the docker command outputs [after hosting VM reboot]:

We found a workaround. Deletion of “/var/lib/docker/network/files/local-kv.db” and restarting docker service seems to be working for us. This is mentioned in . We are in the process of testing this in CI. Please let us know if there are any side-effects of this work-around.

The above mentioned workaround of deleting “/var/lib/docker/network/files/local-kv.db” file and restarting docker has been tested for more than a fortnight now and with this, we are not facing the original issue anymore. So, anyone facing this issue can probably use this workaround. This probably is a genuine issue in docker and needs to be fixed.

just wanted to drop that your workaround helped me too @naanuswaroop

What a pain that this isn’t fixed yet. For me solved it by adding the deletion of the file and a docker restart to /etc/rc.local
