Description
Description
Similar to #11773 I'm seeing docker compose up --watch disconnecting when the container is restarted:

services:
caddy:
image: torarnv/caddy
build: .
restart: unless-stopped
ports:
- "8080:80"
develop:
watch:
- action: sync+restart
path: ./Caddyfile
target: /etc/caddy/Caddyfile
Likely because it temporarily sees that there are no services running.
Adding a keep-alive workaround service "fixes" the issue:
dummy-watch-workaround:
image: alpine:latest
init: true
command: ["sh", "-c", "while true; do sleep 2; done"]
