How to configure Nginx proxy server using Docker container to protect access to web services?

Introduction:

With the rapid development of the Internet, the security of Web services has become particularly important. To protect access to web services, we can do this by using Docker containers and Nginx proxy servers. This article will introduce how to use Docker containers and Nginx proxy servers to configure a secure web service environment, and provide corresponding code examples.

1. What is a Docker container?

Docker is an open source container virtualization platform that can package, publish and run applications. By using Docker, we can package the application and its dependencies into a self-contained container, thereby achieving application portability and consistency.

2. What is Nginx proxy server?

Nginx is a high-performance open source web server and reverse proxy server. It can protect access to web services through features such as load balancing, SSL termination, and access control.

3. Steps to configure Nginx proxy server using Docker container

Step 1: Install Docker

First, we need to install Docker. For the specific installation process, please refer to Docker official documentation. After the installation is complete, we can verify whether the installation was successful by running the following command:

docker --version

Step 2: Create a Docker container

Next, we need to create a Docker container to run the Nginx proxy server . We can create a container named "nginx-proxy" by running the following command:

docker run --name nginx-proxy -p 80:80 -d nginx

In this command, we specify the container name as "nginx-proxy" and map the container's port 80 to the host 80 port, and use background mode to run the Nginx container.

Step 3: Configure Nginx proxy server

Now, we need to configure Nginx proxy server to protect access to the Web service. We can use the following configuration example:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://web-service;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

upstream web-service {
    server web-service-container:8080;
}

In this configuration example, we specify the server listening port as 80 and forward all requests to the upstream server named "web-service". We also set some HTTP request headers to correctly pass the client's information to the upstream server.

Step 4: Start the Web service container

Finally, we need to create a Docker container named "web-service-container" to run our Web service. This can be done by running the following command:

docker run --name web-service-container -p 8080:8080 -d web-service

In this command, we create a container called "web-service-container" and map the container's 8080 port to the host's 8080 port. We also ran a web service container called "web-service" using background mode.

4. Summary

By using Docker containers to configure the Nginx proxy server, we can achieve access rights protection for Web services. First, we installed Docker and created an Nginx proxy server container named "nginx-proxy". We then configured the Nginx proxy server to forward all requests to the upstream server named "web-service". Finally, we created a web service container called "web-service-container" and used it with the Nginx proxy server.

I hope this article has been helpful to you in protecting access to web services.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
