- Introduction to Containers

- Virtualization is the concept of creating virtual machines on top of physical servers.

- Virtual machines often waste resources as they may not fully utilize the allocated capacity.

- Containers solve the problem of wasted resources in EC2 instances.

- Containers are lightweight and reduce maintenance overhead

- Containers use resources from the base operating system or virtual machine, making them lightweight.

- Docker simplifies containerization by providing a user-friendly interface and commands.

- The life cycle of Docker involves writing a Docker file, creating an image, and creating a container.

Introduction to Containers

- Understanding the basics of containers is important before diving into creating projects with containers.

- Explaining what Docker is and its significance in the field of DevOps.

Virtualization is the concept of creating virtual machines on top of physical servers.

- Virtualization allows for the creation of multiple virtual servers on a single physical server, optimizing resource utilization.

- Understanding virtual machines is important before diving into the world of containers.

Virtual machines often waste resources as they may not fully utilize the allocated capacity.

- Virtual machines may not use the full RAM and CPU capacity, leading to wasted resources.

- This drawback applies to EC2 instances as well.

Containers solve the problem of wasted resources in EC2 instances.

- EC2 instances often have unused resources and waste a lot of resources.

- Containers effectively use virtual machines and reduce resource wastage.

Containers are lightweight and reduce maintenance overhead

- Containers are used to create virtual machines on top of physical servers to reduce maintenance overhead

- Containers do not have a complete operating system, unlike virtual machines

Containers use resources from the base operating system or virtual machine, making them lightweight.

- Containers share resources from the host operating system or virtual machine.

- A container is a package that combines the application, application libraries, and system dependencies.

Docker simplifies containerization by providing a user-friendly interface and commands.

- Docker allows you to create containers by writing a Dockerfile and submitting it to Docker engine.

- Docker engine converts the Dockerfile into a Docker image or container image.

The life cycle of Docker involves writing a Docker file, creating an image, and creating a container.

- The Docker engine receives the Docker commands and creates the image and container.

- The commands used are 'Docker build' to convert from Docker file to image, and 'Docker run' or 'Docker exec' to create a container.

Introduction to Containers with Builder

- Docker Builder allows you to create images using a shell script with Builder commands.

- Builder supports Docker images and other OCI compliant images.
