keep container running

Hi, using ldapaccountmanager/lam in kubernetes stops running.
I think the same problem will happen starting using docker-compose.
Can you please change the Dockerfile or document on dockerhub.
Here is a config that works:
...
      containers:
        - name: ldap-account-manager
          image: ldapaccountmanager/lam
          command: ["/bin/sh"]
          args: ["-c", "service apache2 start && sleep infinity"]
