Share wont start becasue of same port

[mangar]

I am trying to docker compose ACS and share.  The ACS comes up fine if I run it individually.  but when I add Share to my docker compose file,  I get this error: 

Removing docker_alfresco-share_1

Here is my docker-compose.yml

    volumes:

volumes:
  alfresco-acs-volume:

How do I tell it to use the same tomcat and the same port?

You can't publish the same port for acs and share in docker. You should change your share ports to:

"8180:8080"

"8889:8888"

Hope this helps

By default, docker compose runs two separate docker images for share and acs, so you get two tomcats running and need different ports for them.

You will need to build your own docker image with share and acs wars deployed to the same tomcat if you want it that way.
