When I run docker compose deploy -c docker-compose.yml myapp_stack_2, it only starts containers for nginx, postgres and redis. Following is the output of watch n -2 docker container ls:

The haproxy containers keeps appearing and disappearing from the list, never remaining stable forever. I checked the logs for haproxy container and this is what it has:
[NOTICE] 141/064759 (1) : haproxy version is 2.3.9-53945bf
[NOTICE] 141/064759 (1) : path to executable is /usr/local/sbin/haproxy

So from haproxy logs, it seems that haproxy fails to start because wsgi container is not starting up. Also nodejs container is not starting up because it depends on wsgi container. Now I am guessing why wsgi container is not starting up? haproxy container appears at least momentarily in the docker container ls command output. But wsgi container never appears even in docker container ls -a command output. It neither appears in the docker events output. Below is my docker events command output:

So am not able to get logs of wsgi container logs and find out why its never started. How can I know why wsgi is not starting up?
Update
Below is the output of docker ps -a if its required. Note that wsgi container appears in the list below, but it was created 12 months back. Also its name has prefix myapp_demo_fm_v2 and not myapp_stack_2. So its log of 12 months older run.
$ docker ps -a

Note that current wsgi container never appear in this list. I guess thats because wsgi container is not started at all when I run docker stack deploy ..., possibly some issue with docker-compose file. Two things I thought could be problematic:
wsgicontainer may fail to start if./wsgi/myappdoes not exist. But it does. I checked.- Port
9090is already occupied. But it is not. I checked withsudo lsof -i :9090.
