Cannot attach external overlay network to container on swarm worker node #8996
Description
Description
I cannot attach an overlay network created in a swarm master node to a container defined in my docker-compose.yml on a swarm worker node.
I think #4601, which seems to be solved in v1.23.0, happened again in compose v2.
Steps to reproduce the issue:
- Setup swarm with two nodes (one master and one worker).
- On machine A (master), run
docker swarm init --advertise-addr <IP address of machine A>and copy thejoincommand - On machine B (worker), run the
joincommand
- On machine A (master), run
- On master node, run
docker network create --driver overlay --attachable example_overlay_network - On worker node, create
docker-compose.ymlwith the following content and rundocker compose up
services:
app:
image: alpine
networks:
- example_overlay_network
networks:
example_overlay_network:
external: true
driver: overlayDescribe the results you received:
docker compose up failed with the following error.
network example_overlay_network declared as external, but could not be foundDescribe the results you expected:
The app container is created and attached to example_overlay_network network.
