This is by far the easiest way to initialize a docker swarm, I'll continue in the next video when we actually deploy to the swarm. As I mentioned, I ran Ubuntu, to install docker you can just: sudo apt install docker.io Then you can add your user to the docker group with: sudo usermod -aG docker $USER then you can run docker commands with your current user: docker swarm init then copy paste to the other nodes, and yes, it's that easy!

This presentation was recorded at GOTO Berlin 2019. #GOTOcon #GOTOber 🤍 Bret Fisher - Docker Captain, DevOps Trainer and Consultant ABSTRACT Learn fast from my years of being a container consultant and Docker implementer. Come join me for a jam-packed session of decisions you need to make and key technical factors you should know. No fluff, all practicals. Updated for 2019 and based on my 3 years of top-10 DockerCon talks. You should show up if: • You are planning or involved with building/using a Docker production system. • You are thinking of using Swarm and/or Kubernetes (but not required). • You like random 80's/90's video game trivia thrown at you. DevOps in the Real World is far from perfect, yet we all dream of that amazing auto-healing fully-automated micro-service infrastructure that we'll have "someday." But until then, how can you really start using containers today, and what decisions do you need to make to get there? This session is designed for practitioners who are looking for ways to get started now with Docker and container orchestration in production. This is not a Docker 101, but rather it's to help you be successful on your way to Containerizing [...] Download slides and read the full abstract here: 🤍 RECOMMENDED BOOKS Liz Rice • Container Security • 🤍 Liz Rice • Kubernetes Security • 🤍 Brendan Burns, Joe Beda & Kelsey Hightower • Kubernetes: Up and Running • 🤍 John Arundel & Justin Domingus • Cloud Native DevOps with Kubernetes • 🤍 Kasun Indrasiri & Sriskandarajah Suhothayan • Design Patterns for Cloud Native Applications • 🤍 Michael Hausenblas & Stefan Schimanski • Programming Kubernetes • 🤍 Alexander Raul • Cloud Native with Kubernetes • 🤍 Nigel Poulton • The Kubernetes Book • 🤍 Marko Luksa • Kubernetes in Action • 🤍 🤍 🤍 🤍 #Docker #Swarm #k8s #Kubernetes #DevOps Looking for a unique learning experience?

In this Docker Swarm tutorial we’ll build the basic Swarm skills that you’ll need in your project work. You’ll learn to set up a Swarm cluster, Deploy applications, explore and manage your stack in the cluster, and we’ll also go through typical maintenance activities that you’ll need. You can find the article form of this tutorial on my blog here: 🤍 This is a code-along tutorial, so please open up your terminal and get ready. We’ll use a two step approach: We’ll set up a cluster and deploy an application first. The goal here is to show you what Swarm is all about and what it’s capable of. We’ll set up a one machine cluster on your local machine first, and then we’ll set up a cluster of two hosts. Once you get the big picture in step 1, I’ll explain all details behind. I think it’s easier to learn and understand after you’ve seen the stuff in action. In order to get the most out of this article you should be familiar with basic Docker concepts, like containers, images, the Dockerfile and Docker Compose. If you need a refresher on these topics, please go to my previous tutorials first. Alternatively you can get my book for a complete guided experience.

Kubernetes vs Docker | Difference between Docker and Kubernetes Docker and Kubernetes are both important tools in the containerization ecosystem. Docker is used for creating and running containers, while Kubernetes is used for managing and automating the deployment, scaling, and operation of containers across clusters of hosts. While Docker is a container runtime, Kubernetes is a platform for running and managing containers from many container runtimes. Kubernetes supports numerous container runtimes including Docker, containerd, CRI-O, and any implementation of the Kubernetes CRI (Container Runtime Interface) check out other shorts AI tools in DevOps: 🤍 Docker and Kubernetes services in AWS : 🤍 Kubernetes for beginners: 🤍 Docker explained: 🤍 #docker #kubernetes
In this Kubernetes vs. Docker tutorial, we will take a look at what Docker, Docker Swarm, and Kubernetes are, their pros and cons, and how they fit into a developer's workflow. If you want to become a full-stack developer, you will need to understand the difference between these technologies, and why and when to use them. When comparing these tools, it’s not about deciding which is better, but which is right for your use case. We hope this Kubernetes vs. Docker vs. Docker Swarm tutorial will help you figure that out. Finally, we will compare Docker swarm vs. Kubernetes as container orchestration tools. By the end of this video, you should better understand what Docker, Kubernetes, and Docker swarm are and which tool is right for your use case. 👉Docker and Kubernetes Monitoring tool: 🤍 👉Logging solution for Containers: 🤍 Additional Resources: 📚Kubernetes Cheat Sheet: 🤍 📚Shipping Kubernetes logs to Sematext: 🤍 📚Top 10 Free Ebooks for DevOps: 🤍 ❤️Subscribe:🤍 🤓Check out our blog: 🤍 Follow Sematext: 👍Facebook: 🤍 👍Twitter:🤍

How does Kubernetes stack up against Docker Swarm? Anyone who's used both will tell you that Kubernetes has a much steeper learning curve. Building work environments is more complicated and getting your mind around the terminology and the many infrastructure elements can be difficult. While Kubernetes can handle any OCI-compliant Docker container you send it, it's not compatible with Docker Compose scripts. One more difference: Unlike Docker Swarm which can run at least one node on any OS, the Kubernetes control plane can only run on a Linux (or macOS) host. Scalability, high availability, and load balancing are built into Kubernetes and, in many senses, automated. Kubernetes also features mature self healing, failover, and rollback management. Kubernetes security employs RBAC-based authorization and authentication - where "RBAC" stands for role-based access control - integrated secrets management, and security policies at both the pod and network levels. Finally, while we've seen Docker's relatively recent Docker Desktop product, Kubernetes has had a built-in and tightly integrated dashboard for as long as I can remember. Interested?

Vamos falar sobre Docker Swarm, uma alternativa ao Kubernets, capaz de dar total conta de pequenos e médios projetos em produção. Possuindo todos os recursos para você orquestrar containers com facilidade. Além disso, o Docker Swarm é muito mais fácil e simples de ser aplicado e utilizado em qualquer ambiente, seja produção ou desenvolvimento. E ele é capaz de permitir que você gerencie recursos com facilidade. Para quem não sabe, aqui quem fala é o Urnau, do Canal Dev Tech Tips Brasil, conteúdo de primeira sobre tudo que vc precisa para se tornar um profissional da área de tecnologia cada vez melhor. Se não for inscrito, já se inscreve agora ficar por dentro dos 2 vídeos por semana que subo aqui! DOCKER SWARM - Managers e Workers Os Workers e Managers são dois tipos de nós que compõem um cluster do Swarm. Os Workers são responsáveis por executar os contêineres, enquanto os Managers são responsáveis por gerenciar o cluster, coordenando as atividades dos Workers e fornecendo uma interface para gerenciar o cluster. Os Managers são os nós principais do cluster. Eles são responsáveis por realizar tarefas como: Gerenciamento do estado do cluster Balanceamento de carga dos contêineres em execução em diferentes nós Gerenciamento do escalonamento de serviços e a configuração das redes e volumes. Os Workers são os nós que executam os contêineres. Eles recebem instruções dos Managers para implantar os contêineres nos nós disponíveis e mantê-los em execução. Os Workers não gerenciam o estado do cluster, eles apenas fornecem recursos de computação para o cluster. O Docker Swarm usa o protocolo Raft para gerenciar o estado do cluster e garantir a consistência dos dados entre os nós. O protocolo Raft é um protocolo de consenso distribuído que garante que apenas um nó do cluster possa realizar mudanças no estado do cluster a qualquer momento. Em resumo, os Workers e Managers do Docker Swarm trabalham juntos para implantar, gerenciar e manter em execução os contêineres do Docker em um cluster. Os Managers são responsáveis por gerenciar o cluster como um todo, enquanto os Workers executam as tarefas do contêiner. 🔗HASHTAGS #docker #dockerswarm #orquestração 💎 CUPONS E DESCONTOS 🔹 Hostiger - Servidores/Hospedagem de sites [Ótimos Preços] + 20% de Desconto pelo Link: 🤍 📋ROTEIRO 00:00 - Introdução 03:00 - Principais características do Docker Swarm 23:00 - Criando um arquivo yml do Docker Swarm 30:00 - Iniciando o Docker Swarm 40:00 - Testando o Docker Swarm 51:00 - Conclusão ▶ VÍDEOS ÚTEIS 📌LINKS ÚTEIS Repositório GitHub 🤍 Doc Oficial Docker Swarm 🤍 🔣COMANDOS ÚTEIS ☑🔘🔴🟠🟡🟢🔵🟣🟤⚫⚪🟥🟧🟨🟩🟦🟪🟫 ⬛⬜◼◻◾◽▪▫🔸🔹🔶🔷🔺🔻🔲🔳
