Description
When deploying a service that has 0 replicas with docker compose, it fails with "no such service: {name}"
We use docker compose with 0 replicas to deploy a service's dependencies without deploying the service itself.
This worked in docker compose 2.2.3, but started failing in 2.3.0 and still fails in 2.4.1.
Steps to reproduce the issue:
- Create the docker compose file:
version: "3"
services:
a:
image: redis:alpine
b:
image: redis:alpine
deploy:
replicas: 0
depends_on:
- a
c:
image: redis:alpine- Run
docker compose up -d b
Describe the results you received:
2.3.0:
$ docker compose up -d b
[+] Running 2/2
⠿ Network tmp_default Created 0.1s
⠿ Container tmp-a-1 Created 0.1s
no such service: b
2.4.1:
$ docker compose up -d b
[+] Running 2/2
⠿ Network tmp_default Created 0.1s
⠿ Container tmp-a-1 Created 0.1s
no such service: "b": not found
Describe the results you expected:
I expect a to be started, as a dependency of b, but not b itself, and not c, as it did in versions <= 2.2.3
2.2.3:
$ docker compose up -d b
[+] Running 2/2
⠿ Network tmp_default Created 0.1s
⠿ Container tmp-a-1 Started
