Easy Docker
is a repository of Dockerfiles, Docker Compose scripts, and other Docker resources, aimed at simplifying the deployment and management of popular applications and services.
- Facilitates consistent development, testing, and deployment environments, ensuring that the software behaves the same way in every stage.
- Supports a microservices architecture, allowing each service to be packaged into a separate container.
- Provides version control for containers, making it easy to roll back to a previous version if needed.
- Offers a vast repository of pre-built images for various software, reducing the setup time.
- Enhances resource utilization as containers are lightweight and start quickly compared to traditional virtual machines.

Term | Description |
---|---|
Docker Registry | A storage system for Docker images that hosts and manages them, facilitating their sharing and distribution. |
Docker Repository | A collection of Docker images that are related, identified by a common name, and differentiated by their versions. |
Docker Images | Self-contained packages that include everything necessary to run applications. |
Docker Container | Lightweight, runnable instances of Docker images. |
Dockerfile | A text file that contains all the commands or instructions needed to build a Docker image. |
Docker Compose | A tool for defining and running multi-container Docker applications. It uses YAML files to configure application's services. |
Docker Swarm | A native clustering and scheduling tool for Docker containers. It turns a pool of Docker hosts into a single, virtual host. |
Docker Hub | A cloud-based registry service for building and shipping application or service containers. It provides a centralized resource for container image discovery. |
Docker Engine | The runtime that runs and manages containers on a host machine. It's the core of Docker and it consists of a server, a REST API and a command line interface (CLI). |
Docker Volume | Provides persistent storage for Docker containers, managing data beyond the container's lifecycle and enabling data persistence. |
Docker Network | Enables communication among Docker containers and between containers and the host, providing networking and connectivity. |
A Dockerfile is a text file that contains all the commands or instructions needed to build a Docker image. It is a simple way to automate the image creation process. Docker reads the Dockerfile and executes the instructions in it to build a Docker image.

Instruction | Description |
---|---|
FROM | Specifies the base image for the Docker image |
WORKDIR | Defines the working directory for the following Dockerfile instructions |
COPY / ADD | Transfers files and directories from the host machine to the Docker image. ADD supports URLs and automatic decompression of files |
ENV | Establishes environment variables within the Docker image |
RUN | Runs commands during the Docker image build process |
EXPOSE | Indicates the ports the container listens on |
ENTRYPOINT / CMD | Sets the default command for a container. CMD can be overridden at runtime, ENTRYPOINT cannot |
ARG | Defines a variable that users can pass at build-time to the builder with the docker build command |
USER | Sets the user name or UID to use when running the image and for any RUN, CMD and ENTRYPOINT instructions that follow it in the Dockerfile |
VOLUME | Creates a mount point with the specified name and marks it as holding externally mounted volumes from native host or other containers |
