How do I get a tomcat conatiner up and running on GCP

Question

So I have the server… following the instructions on google cloud platform

I have the docker images downloaded thereon server and running with following properties:

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

60b206130ef1 tomcat:7 “catalina.sh run” 6 hours ago Up 6 hours 0.0.0.0:32768->8080/tcp hopeful_hoover

I have my external IP-adress for my docker-server (I assume this would also be my docker host as far as I understand)
That server has a firewall that allows http and https traffic…

So what else do i want to try and do to see the homepage of tomcat besides typing my external server ip-adress:32768 in my native browser ?

Answer 1

You are running that container on port 32768. You will probably want to specify what port to map that to rather than allowing docker to choose one for you.

Instead of doing docker run -P or docker run -p 8080, you can specify the port like this: docker run -p 80:8080. That will bind your tomcat’s 8080 to your docker host’s port 80. Your firewall should allow that connection to happen.

Try this:

sudo docker run -d -p 80:8080 tomcat:8.0
