What does it mean when docker is listening on 8080?

ANSWER

The 'listening on 8080' is a message coming from the container. It is listening on port 8080 inside the container, but then docker may expose that internal port as a different port on the host. The port that is relevant to you is the docker-exported port, which may or may not be the same as the one in the container. Glad you got it worked out.

Docker: Listen on port 80? Hi there, I'm using the stock NodeRed docker image and I need it to listen to port 80. The container is running on Azure container instance.

Docker? sudo docker run -p 8080:8080 -p 50000:50000 jenkins The left-hand side of the port number mapping is the Docker host port to map to and the right-hand side is the Docker container port number.

DOCKER-341: Remapping ports with -p (eg, -p 80:8080) is ? The canonical example is Apache Tomcat. When running it as a non-privileged user you will need to use authbind to have it listen on port 80. This is a bit of a nightmare to get setup correctly in Docker. Moreover, I've had applications totally refuse to play with authbind inside docker. In those cases, port forwarding was a savior.

Docker networking IPv6 exposed?

This is the docker-proxy process that manages the host port. When you use "-p 8080:80", docker-proxy bind a tcp6 socket on the host ::0 listening on port 8080 (and tcp6 sockets accept tcp4 also). So a disabled ipv6 support on docker (default) means your containers only have ipv4 assigned, but docker-proxy "translate" v6 to v4 :

How To Use the Official NGINX Docker Image? $ docker run -it --rm -d -p 8080:80 --name web nginx. With the above command, you started running the container as a daemon (-d) and published port 8080 on the host network. You also named the container web using the --name option. Listening on port 8080

Docker Networking 101 – Mapped Container Mode – Das ? In this blog I’ll be using two docker images… web_container_80 – Runs CentOS image with Apache configured to listen on port 80 web_container_8080 – Runs CentOS image with Apache configured to listen on port 8080.

How to Implement Docker Health Checks by Nassos Michas ?

Let’s start by creating the simplest Docker container using the following Dockerfile: FROM nginx:1.17.7. Build the image, and start a container: docker build -t docker-health . docker run --rm --name docker-health -p 8080:80 docker-health. An NGINX container is now running and listening on local port 8080.

How to Set Up Remote Access to Docker Daemon [Detailed Guide]? By "remote local DOCKER_HOST" I mean the local DOCKER_HOST of the remote server.

How to deploy on remote Docker hosts with docker-compose ? The docker-compose tool is pretty popular for running dockerized applications in a local development environment.
