I'm trying to set up a simple Docker container using the Debian image, but I'm facing an issue. Here's my Docker stack file:
```yaml
version: '3.7'
services:
es01:
image: debian:latest
container_name: debian
deploy:
replicas: 1
networks:
debian_default:
driver: overlay
```
When I run `docker stack deploy -c debian.yml debian`, I notice that the container isn't starting properly, and I'm receiving the following output:
```
ID NAME MODE REPLICAS IMAGE PORTS
1yd50hgisosw debian_es01 replicated 0/1 debian:latest
```
I need help figuring out how to keep the container running!

To keep your Debian container running, you need to specify a command for it, like `sleep infinity`. This ensures that an active process (PID 1) is running inside your container. Your updated Docker stack file should look like this:
```yaml
version: '3.7'
services:
es01:
image: debian:latest
container_name: debian
command: 'sleep infinity'
deploy:
replicas: 1
networks:
debian_default:
driver: overlay
```
With this change, your container should start without any issues!
You need to start a process (PID 1) in your container for it to stay up. The `sleep infinity` command is a perfect solution because it keeps the container running. If you want to know more about creating long-running processes inside a container, just let me know!
