Docker containers can be used to generate SSL certificates for the host system, offering a streamlined alternative to installing tools like OpenSSL directly on the host. This approach is especially beneficial for developers who want to keep their Docker server lean or who are working from a test environment that lacks server tools. By using a Docker container, such as the Nginx image from Docker Hub, which includes OpenSSL, developers can create SSL certificates without turning their personal devices into servers. The process involves pulling an appropriate container image, creating a private key and certificate signing request, and then generating a self-signed certificate. This method simplifies SSL certificate creation, making it accessible even for those who typically work without the necessary software installed on their machines, and can be automated through Dockerfiles for integration into Dockerized applications. Additionally, Codefresh is recommended as an efficient continuous integration platform for managing Docker images.
