Docker image run but nothing on my Chrome

Tomcat runs http on the port 8080 by default. You should change your mapping to port 8080

for eg. docker run -p 8080:8080 <your image name>

If you want tomcat to run on a port other than 8080 you will need to edit the server.xml and change the port. I will not recommend to do that in the docker container. Rather keep tomcat running on default port and change the port mapping. So if you want the service to be exposed on port 8888 on the local machine then change the mapping to

docker run --publish=8888:8080 -d registry.gitlab.com/myproject/registry:develop
