Change Root Directory Nginx To Host Docker
What is a Root Directory?
A root directory is the top-level directory on a file system that is used for the storage and organization of all other directories and files on the system. It contains all other directories and files, and is the main starting point for all paths in a file system. On a web server, it is common for the root directory to be referred to as the document root, and is the directory from which the server will serve files when requested.
Why Change the Root Directory?
On a production server, it is generally important to secure the root directory and its contents from unauthorized access. Therefore, it is beneficial to change the document root to a directory outside the root directory. This makes it difficult for malicious actors to find and access files, and also prevent users from using the root directory itself to store files.
Prerequisites for Changing the Document Root
Before changing the document root, there are a few requirements that must be met. First, all necessary files and directories must be available in the new root directory. Second, the new root directory must have the appropriate permission set for the user running the webserver. Third, it is important to set up a security configuration to protect the new root directory if it is not already in place.
Setting the Document Root with Nginx
Nginx is a popular web server used for serving dynamic content. In order to set the document root for Nginx, the server needs to be configured. This can be done either through a configuration file, or by using the nginx command line tool. In both cases, the root directory can be changed by updating the ‘root’ directive in the server block.
Hosting Docker Web Apps with Nginx
Docker is a container technology that allows developers to package and deploy applications with all the required dependencies. It can be used to deploy web applications, and Nginx can be used to serve these applications with a custom document root. This means that Nginx must be configured to serve content out of the application’s docker container, rather than its root directory.
Conclusion
Changing the root directory for a web server is an important security measure, and can be done with Nginx. It is possible to change the root directory to a directory outside the root directory, or to the root directory of a docker container. Regardless of the chosen directory, it is important to ensure that the appropriate permissions are in place to ensure security of the files and directories.
