Docker Container Access External Network Code Running In
You would like to provide access to external consumers – yourself on your smart phone, a piece of code running in a cloud environment, a colleague on your local network or on the other side of the world. I can access the docker container from external network using the host's ip address/ port but not via the url server.dev:8880 How do I access a container using it's domain name in docker-compose domain-name-system docker docker-composeThe challenge: you are running a service, API or web application in a Docker container, locally on your laptop or in a cloud based VM or container platform. The least complex of the external networking configurations, this type is. Host: This configuration allows a created container to share the host’s network namespace, granting the container access to all the host’s network interfaces. Bridge network is the default for Docker containers. Containers cannot be accessed from outside the host.
We can access web from the outside world via port 8000 on the Docker host (only because the web service explicitly maps port 8000. Pinging any server (external dns, docker dns, bashcontainer) fails to. Starting a bash container in the docker-network (created through compose) and pinging the target server from there resolves correctly.
Run a docker network ls command to view existing container networks on the current Docker host.Assuming you are working on a Docker host – a system that can run Docker containers, here are some steps to try out: First steps with ngrok and DockerA network container is created to facilitate a single network stack per pod. It also allows you to connect and disconnect containers from networks. See for an introduction to ngrok.As you can see from the output, the docker network command allows you to create new networks, list existing networks, inspect networks, and remove networks. It generates a public URL and ensures that all requests sent to that URL are forwarded to a local agent (running in its own, stand alone Docker container) that can then pass them on to the local service. When you run docker-compose up to updateIn this article, we will look at how ngrok – a tool and a cloud service – makes this happen. You can change service configurations via the Docker Compose file.

The containers are linked through a Docker network. One container with a Node JS runtime and a custom Node application (cloned from GitHub) and the other with the ngrok client. You can verify this from the Docker Host (or possibly the Windows host: VM IP>:8080/?region=Europe.Run the ngrok Docker Container to create a tunnel from the a newly assigned public URL to port 8080 on the json-server container (at which the Node application is handling requests )Docker run -d -p 4040:4040 –net myngroknet –name ngrok wernight/ngrok ngrok http json-server:8080Inspect ngrok at port 4040 and learn about the public url – or use curl $(docker port ngrok 4040)/api/tunnels to get that url.Access the Node application from any client anywhere in the world (for example your mobile device) at the url: ngrok id>.ngrok.io/?region=EuropeTwo containers on a Docker host – which can be a local one or a cloud based host. Perform the following steps to copy the sources, install dependencies and run the Node application:The Node application is up and listening at port 8080. The request from the browser should be handled by the Docker Container, in this case the The container is associated with the myngroknet network that makes it accessible later on to the container running ngrok.Docker run -it –rm -p 8080:8080 -v “$PWD”:/usr/src/app –net myngroknet –name json-server node:10 bashOnce the container is started, you will find yourself in a shell in the container. In host.Define a logical network myngroknet to link two or more containers together:Run a Docker Container called Specify that ngrok should open a tunnel (expose a public url) for HTTP requests to port 80 on container that URL from any browser on any machine anywhere in the world.
