Now let us go and create the Docker Images. In our case, we are going to build our images using the Dockerfile The first step to create a container is to have the image ready. I presume that you have downloaded these files in the same directory structure.

You can simply download the resources required for this post as a ZIP file or clone my Github Repository ➜ tree haproxy-nodejs-redis Refer to the following Directory Structure tree with all necessary files we need for this post. We are going to use three technologies in this post and we are going to create our own Docker images by writing Dockerfile and we also need to write some configuration files for HAProxy and Javascript program files for NodeJS containers. Once the containers are connected on the same network they can communicate to the other container docked to the same network freely by just knowing the name of the other container. All these methods do the same thing at the backend which is creating a shared bridged network and attaching these containers to them. Note*: Though we have different methods to achieve the same docker container intercommunication or connectivity between containers. Redis DB – A Small Key-Value Database to store data.Node JS – Java Script based Application Server Framework where the App is hosted.HA Proxy – Edge Level Load Balancer and Reverse Proxy like F5 Big IP.In order to demonstrate the various methods to connect docker containers, I need some easily relatable objective.Ĭonsider the following Design of infrastructure with three different technologies running in the container comes together to make an enterprise like web application. Basic Knowledge on Apache HTTPD web server and Tomcat (Optional).

These are the methods we are going to be discussing in detail with examples in this post Three methods to Create Docker network between containers

MetricFire is a cloud infrastructure and application monitoring platform that makes it easy to manage and monitor your Docker containers. Improve Docker network performance with a MetricFire free trial and Schedule a demo. įor more information about the various Docker network options, check out our article " Understanding Docker's -net=host Option." However, users need to take care to avoid port conflicts while working in Docker host networking mode.

In addition, Docker host networking does not require network address translation (NAT), making it easier to handle a large number of ports simultaneously. Why use Docker host networking mode? Docker network host can offer performance improvements and optimizations over other Docker networking modes, e.g., "none" and "bridge" modes. What are the Use Cases of Docker Network Host? The application inside the container can be accessed using a port at the host's IP address (e.g., port 80).īelow is an example Docker command to run a container in host networking mode:ĭocker run -it -name web2 -net=host vaibhavthakur/docker:webinstance2

Docker network host , also known as Docker host networking, is a networking mode in which a Docker container shares its network namespace with the host machine. In Docker, the host is a machine responsible for running one or more containers. Schedule a demo to see how MetricFire can help you monitor your Docker network. Below, we'll answer the question: "what is Docker network host?". To start using Docker containers, you need to be familiar with Docker networking.
#Docker network host contaienr failing software#
Containers are software "packages" that bundle together an application's source code with its libraries, configurations, and dependencies, helping software run more consistently and reliably on different machines. What are the Use Cases of Docker Network Host?ĭocker is a platform as a service for deploying applications in Docker containers.
