The containers being proxied must expose the port to be proxied, either by using the EXPOSE directive in their Dockerfile or by using the --expose flag to docker run or docker create and be in the same network.

By default, if you don't pass the --net flag when your nginx-proxy container is created, it will only be attached to the default bridge network. This means that it will not be able to connect to containers on networks other than bridge.

Provided your DNS is setup to forward foo. This image is based on the nginx:alpine image. A valid certificate is required as well see eg. If your container exposes multiple ports, nginx-proxy will default to the service running on port If you need to support multiple virtual hosts for a container, you can separate each entry with commas. For example, foo. Or even a regular expression, which can be very useful in conjunction with a wildcard DNS service like xip.

With the addition of overlay networking in Docker 1. At the time of this writing, only a single network can be specified at container creation time.

To attach to other networks, you can use the docker network connect command after your container is created:. In this example, the my-nginx-proxy container will be connected to my-network and my-other-network and will be able to proxy to other containers attached to those networks. If you allow traffic from the public internet to access your nginx-proxy container, you may want to restrict some containers to the internal network only, so they cannot be accessed from the public internet.

By default, the internal network is defined as Please see the nginx realip module configuration for more details.As requests come into my server, Apache routes them to the appropriate application via virtual hosts.

Dynamic host multiple websites on the same server and port with Docker and Nginx

Each application is a different directory on the virtual private server VPS. If I were to containerize each application, things would behave a bit differently. I would need to set up a reverse proxy to route each request to a different container on the host. While Apache can work as a reverse proxy, there are other options that work way better.

The nginx and apache services will use each of their respective images and depend on the reverseproxy service being available. Only ports in the reverseproxy service are exposed to the host machine.

Only a server name like example1. The custom image representing our reverse proxy will need a Dockerfile file as well as a custom NGINX configuration file. During the build process, our configuration file will be copied into the image.

First of all, notice the upstream declarations. We have two upstreams because we have two web applications. The server inside each of the upstreams represents where to find each of the applications. The hostname must match the service name found in the docker-compose. After defining the upstream servers we need to tell NGINX how to listen and how to react to requests. Take for example the following:. In the above scenario we have docker-nginx which is the name of one of our upstream servers.

Before we can launch our containers, we need to build our reverse proxy image. This can easily be accomplished by executing the following command:.

The docker-compose.Software developer and architect interested in scalability, performance and distributed systems. A reverse proxy server is a server that typically sits in front of other web servers in order to provide additional functionality that the web servers may not provide themselves.

When running web services in docker containers, it can be useful to run a reverse proxy in front of the containers to simplify depoyment. Docker containers are assigned random IPs and ports which makes addressing them much more complicated from a client perspsective. By default, the IPs and ports are private to the host and cannot be accessed externally unless they are bound to the host.

Binding the container to the hosts port can prevent multiple containers from running on the same host. For example, only one container can bind to port 80 at a time. This also complicates rolling out new versions of the container without downtime since the old container must be stopped before the new one is started. A reverse proxy can help with these issues as well as improve availabilty by facilitating zero-downtime deployments.

Setting up a reverse proxy configuration can be complicated when containers are started and stopped. Typically the configuration needs to be updated manually which is error prone and time consuming. In addition, it also provides a real-time events API that can be used for notifications when containers are started and stopped.

docker react nginx reverse proxy

These APIs can be used to generate a reverse proxy config automatically. Templates are rendered and an optional notification command can be run to restart the service. Using docker-genwe can generate Nginx config files automatically and reload nginx when they change.

The same approach can also be used for docker log management. This example nginx template can be used to generate a reverse proxy configuration for docker containers using virtual hosts for routing. This simplifies iterating over the containers to generate a load-balanced backend and also enables zero-downtime deployments. The template can be run with docker-gen using:. I created a trusted build with this setup to make it easier to try it out:.

If you need HTTPS, would like to run docker-gen in a separate container from nginx, Websocket support or other features, take a look at the github project for more information. Generating nginx reverse proxy configs for docker containers can be automated using the Docker APIs and some basic templating. This can simplify deployments as well as improve availability. While this works well for containers running on a single host, generating configs for remote hosts requires service discovery.

Take a look at docker service discovery for a solution to that problem.

Generating Reverse Proxy Configs Setting up a reverse proxy configuration can be complicated when containers are started and stopped.I am building an application that will use React for a static frontend paired with a graphql backend all behind nginx.

I am trying to use nginx as a static file server for the React app and as a reverse proxy for my graphql api. One docker container holds the nginx server and React files, the other docker container runs the graphql api. I have even tried cURLing all of the static assets that react could be fetching successfully. Still, however, none of the css, svgs, or images want to load.

I am running a completely untouched create-react-app. If you would like any other screenshots or files uploaded that would be useful to give me a pointer just let me know.

If you just want authentication for your registry, and are happy maintaining users access separately, you should really consider sticking with the native basic auth registry feature.

With the method presented here, you implement basic authentication for docker engines in a reverse proxy that sits in front of your registry. While we use a simple htpasswd file as an example, any other nginx authentication backend should be fairly easy to implement once you are done with the example.

We also implement push restriction to a limited user group for the sake of the example. Again, you should modify this to fit your mileage. While this model gives you the ability to use whatever authentication backend you want through the secondary authentication mechanism implemented inside your proxy, it also requires that you move TLS termination from the Registry to the proxy itself.

Note : Docker does not recommend binding your registry to localhost without authentication. This creates a potential loophole in your Docker Registry security. As a result, anyone who can log on to the server where your Docker Registry is running can push images without authentication.

Furthermore, introducing an extra http layer in your communication pipeline makes it more complex to deploy, maintain, and debug. Make sure the extra complexity is required. So if you have an Nginx instance sitting behind it, remove these lines from the example config below:. For more information, see Review the requirementsthen follow these steps.

Gotchas While this model gives you the ability to use whatever authentication backend you want through the secondary authentication mechanism implemented inside your proxy, it also requires that you move TLS termination from the Registry to the proxy itself.

The registry always sets this header. In the case of nginx performing auth, the header is unset since nginx is auth-ing before proxying.

See the map directive above where this variable is defined. If you don't need to use bcrypt, you can use a different tag.
