A question which always gets asked regarding the union layered filesystem for images is whether the intermediary image layers can be merged into one? The answer is yes, you can squash image layers during a bulid from a Dockerfile.  The attached video shows 2 example builds of the same Dockerfile, one is standard, the second using squash to merge the layers. #docker #containers

I'm always surprised how few people know about Docker Multistage builds. I've even see people manually try and replace a Multistage build with two regular docker builds. When you start up your first Kubernetes cluster for the first time you probably realize just how expensive cloud resources can be. So if you can reduce the size of your Docker images and containers by 85% with just 4 lines of code ... you might want to go for it! Background in Thumbnail image from Dimound via pngtree.com

A Docker image consists of several layers. Each layer corresponds to certain instructions in your Dockerfile. The following instructions create a layer: RUN, COPY, ADD. The other instructions will create intermediate layers and do not influence the size of your image. V1-14.

This video will explain how docker manages data relating to containers and images on the host machine. This should be useful for recovering data from docker containers which may have been stopped or corrupted in some way. Layers of a Docker image are essentially just files generated from running some command. You can view the contents of each layer on the Docker host at /var/lib/docker/aufs/diff. Layers are neat because they can be re-used by multiple images saving disk space and reducing time to build images while maintaining their integrity. What are the layers? Docker containers are building blocks for applications. Each container is an image with a readable/writeable layer on top of a bunch of read-only layers. These layers (also called intermediate images) are generated when the commands in the Dockerfile are executed during the Docker image build. #docker #containers #vm

If you skip this, it will be challenging to get ahead in Docker realm. So, let begin with Images or Docker Images. An image is a collection of filesystem layers and some metadata. These images are made up of one or more Layers in addition with metadata. If you know Object oriented programming already, you can assume images similar to classes. A class can have multiple objects so does the images. Images include metadata. Metadata is a data about the data. The metadata has information on environment variables, port mappings, volumes. visit: 🤍
