An application image runs in multiple environments, with each environment using different certificates and ports. Is this a way to provision configuration to containers at runtime?
Create a Dockerfile for each environment, specifying ports and Docker secrets for certificates.
B While technically possible, creating a separate Dockerfile for each environment is not the most efficient or scalable way to manage configurations that vary across environments.
B is correct.
Creating separate Dockerfiles for each environment: * Violates the "build once, run anywhere" principle * Makes maintenance more difficult * Increases the risk of configuration drift * Requires rebuilding images for configuration changes * Goes against Docker best practices The better approaches for handling environment-specific configurations - Using Docker Configs and Secrets, Using Environment Variables, Using Docker Volumes.
