Docker Socket Proxy is a lightweight reverse proxy designed to enhance security when interacting with the Docker API. By providing a controlled interface to the Docker socket, it limits access to specific endpoints, which helps protect the host system from potential vulnerabilities. This solution is particularly useful in multi-tenant environments or when running untrusted applications, as it allows you to define granular permissions and restrict operations that can be executed through the Docker API.
With Docker Socket Proxy, you can configure rules to expose only a subset of the Docker functionality, which minimizes the attack surface and boosts overall security. It also provides the ability to implement authentication, logging, and rate limiting, making it a robust choice for users looking to self-host applications with Docker while maintaining a focus on security and control. This tool is especially advantageous for developers and system administrators wanting to manage their Docker containers with added safeguards against potential abuses or exploitation.
