Description
A warm welcome to the Docker Essentials for Cloud and DevOps Professionals course by Uplatz.Docker is an open-source platform that enables developers to build, ship, and run applications inside lightweight, portable containers. Containers package an application and its dependencies together, ensuring consistency across development, testing, and production environments. Docker eliminates the "it works on my machine" problem by providing a consistent runtime environment.Docker is widely used for microservices architectures, DevOps workflows, and simplifying deployment processes across environments.How Docker WorksContainerizationDocker uses containerization technology to isolate applications from the underlying system. Containers share the host operating system kernel, making them more lightweight and efficient than traditional virtual machines.Docker ArchitectureDocker Engine: The core runtime responsible for creating and managing containers.Docker Client: A command-line interface (CLI) that interacts with the Docker Engine.Docker Images: Pre-configured application blueprints used to create containers.Docker Hub: A cloud-based registry for storing and sharing Docker images.WorkflowDevelopers write a Dockerfile containing instructions to build an image.The image is created using the docker build command.The image is then used to launch containers using the docker run command.OrchestrationTools like Docker Compose and Docker Swarm allow users to manage multi-container applications and scale them efficiently.Core Features of DockerContainerization: Run applications in isolated environments to ensure consistency across platforms.Portability: Docker containers can run on any system that supports Docker, whether on-premises or in the cloud.Lightweight: Containers share the host OS kernel, using fewer resources compared to virtual machines.Scalability: Easily scale applications horizontally by creating multiple container instances.Docker Hub: Provides a central repository for discovering, pulling, and sharing container images.Versioning: Allows version control for images, enabling rollbacks to previous builds.Security: Provides container isolation to minimize application vulnerabilities.Efficiency: Enables faster application development and deployment through CI/CD pipelines.Automation: Supports tools like Docker Compose for defining and managing multi-container applications.Orchestration Support: Includes built-in orchestration with Docker Swarm and compatibility with Kubernetes.Docker Essentials for Cloud and DevOps Professionals - Course Curriculum1.
