Container needlessly recreated and then won't start on docker-compose up (original) (raw)
Description
Following a change introduced in 2.3.4
, most likely #9261, we're hitting a scenario where a container is recreated when it needn't be, and then will fail to start following that
Steps to reproduce the issue:
- Create a
docker-compose.yml
similar to the below:
version: '3.7'
services:
db:
image: postgres:11
hostname: postgres
container_name: engage-db
ports:
- "5437:5432"
environment:
- POSTGRES_DB=somedb
- POSTGRES_USER=someuser
- POSTGRES_PASSWORD=somepassword
wait-for-db:
image: postgres:11
command: [ sh, -c, "until pg_isready --username=someuser --host=db --port=5432; do sleep 5; done" ]
links:
- db
- Ensure
postgres:11
is not already in the docker image cache - Run
docker-compose up -d db
to start the db in the background, this will also pull thepostgres:11
image. - Run
docker-compose up wait-for-db
to start the wait in the foreground
Describe the results you received:
When the last step is run to start the wait-for-db
container, it will result in the db
container being recreated, despite the image etc. not having since been rebuilt or changed in any way:
$ docker-compose up wait-for-db
[+] Running 2/2
⠿ Container engage-db Recreated 0.3s
⠿ Container engage-wait-for-db-1 Created 0.1s
Attaching to engage-wait-for-db-1
Following this, the recreated db
container will also not be running, it will be sat in a Created
state:
125fee896799 postgres:11 "docker-entrypoint.s…" About a minute ago Created engage-db
$docker inspect 125fee896799

If you stop everything docker-compose down -v
and try again now the image postgres:11
is already pulled, the container is not recreated and everything works as expected.
Describe the results you expected:
The container should not be recreated as nothing has changed about the image. Adding --no-recreate
on the second compose command also works around the issue, but I don't believe the behaviour is correct currently on two points:
- The container shouldn't be recreated
- If a container is recreated, it should start back up
