Learn the fundamental distinction between containers and virtual machines. This comprehensive course takes you through the complete container lifecycle and the various stages of development. You will receive training on installing Docker across multiple platforms, creating your first container and image, pushing and pulling from the registry hub, and installing your own local registry. Master volumes, container networking, container orchestration, and container debugging techniques. You will build an HTTP server image, run it as a service, and connect to it. Additionally, you will learn how to create a swarm and prepare your containers for production environments.
Course Audience:
- This course suits developers, operations managers, and IT professionals who wish to learn Docker and containerization technologies.
Requirements:
- No prior knowledge of Docker is required to begin this course.
- Docker is open-source software, so no subscriptions are necessary.
