I think something is going wrong with the port mapping here. If I am reading the Dockerfile reference correctly, to expose multiple ports use multiple EXPOSE lines, like
EXPOSE 8080 EXPOSE 9830 Additionally, you need to still use the -p or -P flags on docker run to really expose the ports. Try being very explicit about all the ports: docker run -p 8080:8080 -p 9830:9830 … Then see if you can curl both ports. /MR On Fri, Nov 19, 2021, 17:14 sarbajit das <[email protected]> wrote: > Hi All, > I trying to deploy a small application in a tomcat docker container and > trying to monitor the container using Prometheus with the help of node > exporter.
