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 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

Hello Everyone So in the last video, we started talking about Docker Architecture and will continue to do so in this video as well. Let's pick up from where we left and talk about Union FS, so I told you that UnionFS enables docker to efficiently manage the storage of image layers and it presents multiple filesystems as a single mount. Here we are specifically going to talk about overlay2, which is the docker storage driver that implements unionFS Overlay2 has few layers - The base layer - this is the root layer of an image and is read-only - this is similar to the root filesystem of Linux. This is what you download when you fetch an image from docker hub Next, we have an Overlay layer - This you can consider as a working directory for users. So when you run a container, this layer gives the union view of base and diff layer Last we have a diff layer: So when you change or modify a file in the base layer, those automatically stored in this layer. when you make a change to file that is present in the base layer, overlayfs will copy that file to diff layer and make the modifications. This is called copy on write. UnionFs present a lot of benefits 1) efficient storage management - it is because of this you can run several containers from a single image without exhausting your disk space. 2) Isolation of changes to container filesystem - this lets you start and stop containers with each container preserving its content.

Les layers ou couches sont des éléments très importants pour comprendre le fonctionnement de docker et de ses conteneurs / images. Il existe 2 types de couches : - lecture seule - lecture / écriture Dans cette vidéo vous découvrirez comment sont fabriquées les couches à partir d'un dockerfile. La commande docker history apppliquée sur une image permet de visualiser les couches. La commande docker diff appliquée sur un conteneur permet de visualiser les modifications que le conteneur apporte sur les couches de lecture de l'image.

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

Hello Everyone Welcome back to the channel and in this video we are going to talk about docker images. You must've heard that in linux everything is a file, similarly in docker, everything is a layer Docker images can be considered as a template that is used to launch containers But this templates is not a monolithic block instead it's composed of several layers. The first layer is called the base layer on top of which other layers are built. All these layers are immutable. This immutablity lets us launch several containers from a single image and all these layers are presented a single mount using union filesystem which we have already discussed. Also when we launch containers, what we are doing is actually creating a read-write layer on top of all these layers, so incase you want modify anyfile that is present in the lower layer, that file is first copied to the r/w layer and then modified, which is also called copy on write There are different ways to create an image First is creating image from a running container, also called the interactive way and second way is using a dockerfile. In this video we see the first way because we will have a different section for dockerfile.
In this video we will be learning why is Docker Container essential, what is Docker and Containers?, what is virtualization, Vm vs. Docker Container, benefits of Docker Container, architecture of Docker, how Docker Container works, and how to create Docker Containers. Docker is an open-source platform that helps a user to package an application and its dependencies into a Docker Container for the development and deployment of software. Containerization includes all dependencies (frameworks, libraries, etc.) required to run an application in an efficient and bug-free manner. With Docker Containers, applications can work efficiently in different computer environments. 🔥Free Docker Course: 🤍 Below are the topic we will be looking in the video: 1.

Sick of getting paged at 2am and wondering "where did all my disk space go?" This has actually happened to me, and you can learn from my mistakes! New Docker users often start with a stock image in order to get up and running quickly, but that isn't always the right answer. Creating efficient images is often overlooked, but important. Beyond saving resources, using minimal images also delivers important security benefits: include only what you need and not a whole runtime that might have security vulnerabilities. In this session, I'll talk about how to create effective images and lessons I've learned from running containers in production at a number of startups. I'll also cover topics like "how do layers work?" and some things you should think about when creating your images, such as; choosing or creating the right base image; the importance of caching; using RUN statements conservatively; cleaning up as you go. I'll also address best practices; both at a high level with multi-stage builds; and some language-specific best practices, for example, tips and tricks for creating containers for Node.js vs Go. To illustrate these points, we'll cover: * How layers work? * Choosing a base image vs. creating your own * The basics of building minimal images and the importance of choosing a base image vs. creating your own * The basics of building minimal images and the importance of caching * High level best practices for Linux containers (in general, and some language specific examples) * High level best practices for Windows container images * New and improved: multi-stage builds * Good vs. not so good Dockerfile examples * Docker Image Scanning, and other friends * What's up next? Looking to the future for more optimization.
In this video we will create a custome docker image using a dockerfile. This will allow us to create an image with node.js installed, plus all of our dependencies, and our source code copied over. ▬▬▬▬▬▬ Full Playlist 🌴 ▬▬▬▬▬▬ Devops with Docker and Node.js: 🤍 In this course we are going to master the core fundamentals of docker by building a Node/Express app with a Mongo & Redis database. We'll start off by keeping things simple with a single container, and gradually add more complexity to our app by integrating a Mongo container, and then finally adding in a redis database for authentication. We'll learn how to do things manually with the cli, then move on to docker compose. We'll focus on the challenges of moving from a development environment to a production environment. We'll deploy and Ubuntu VM as our production server, and utilize a container orchestrator like ▬▬▬▬▬▬ Subscribe to my Channel 🍆 ▬▬▬▬▬▬ 🤍 ▬▬▬▬▬▬ Support this garbage Channel 🍒 ▬▬▬▬▬▬ Patreon: 🤍 ▬▬▬▬▬▬ Stalk me on Social Media 😲 ▬▬▬▬▬▬ 🤍 🤍 🤍

CircleCI recently released a new fleet of Docker images, which we call convenience images. These images were built with fewer layers making them more efficient. When a build starts, the new images will download faster and they will only be rebuilt for security and critical bugs.
