The blog post provides a guide on enabling Docker Remote API on Docker Machines created on Mac OS X, specifically addressing the challenges faced by users on OSX Mavericks due to updates in the curl utility that uses Apple's Secure Transport API instead of OpenSSL. It details the process of converting certificates to the P12 format required for successful communication with the Docker daemon via the Remote REST API. The author explains how to generate the necessary P12 certificate using OpenSSL and demonstrates how to use the updated curl command to interact with Docker, including retrieving image details and running a container. The post concludes with examples of invoking the REST API to manage Docker containers, emphasizing the importance of using the correct certificate format and password for secure access.
