For instance, you can bind port 8080 of the container with an arbitrary port on your computer, like 8081:. The easiest way to run it is: docker run -d -p 7000:7000 -p 7001:7001 -p 7199:7199 -p 9042:9042 -p 9160:9160 cassandra:2. The sidecar listens on port 443 and forwards all requests to foo which in turn consumes bar. FROM node:lts It's interesting to see that you answer, since you seem to be the original reply to the question I posted, where you said: "If I re-introduce the KC_HOSTNAME_PORT setting, I get In this line docker run -it --rm -p 5000:80 --name aspnetcore_sample aspnetapp you are mapping the internal port (within the docker container) of 5000 to an external port (outside In this scenario, nginx would serve the requests to the appropriate applications. dev, and depending on that - they proxy it to appropriate php-fpm The first port : the Docker host ( you can use this port to access to your container) to access to the container from the outside. Here is a working docker-compose. ) localhost:8080 for frontend, localhost:3000 for backend. And, as long as any ports you expose on the host are unique, you're good too. When I visit the app deployed to Cloud Run, the frontend initially loads for a split second, but then the app crashes as it attempts to It's a process corresponding to docker-proxy and, per the process, it maps the host's :3000 to a container port :80. EXPOSE is to say It only makes sense if the second nginx runs inside the docker container. Each I am at the end of a project where I have an Nginx as a router in a docker container that works with a test node app on port 8000, but I need it to point to another Nginx Docker Learn how to harness the NGINX Docker Official Image from running a basic server to shipping the image. Different from mostly docker implementations, Nginx doesn't support such configs by using I'm trying to run multiple docker containers all running nginx listening on port 80, but with different host ports mapping to the containers port 80.
