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.

NOTE: As advised by Portainer, please use the "portainer/portainer-ce" image, which is 2.x version, not the older "portainer" tag you see in the compose file here! Support me on Patreon! 🤍 I put a lot of time in to these videos, and your support is appreciated to ensure I keep making high-quality content that’s helpful and educational to you! Deploy Portainer on Docker Swarm easily with proper Compose file! This will place a Portainer Agent container on each node, and deploy the WebUI container, all in one simple step! If you add more nodes in the future, it will automatically deploy the agent to the new node, so you can manage them in the Web UI! We'll start out with docker swarm join to add a worker node to our docker swarm cluster. Follow along!
So Kubernetes has dropped support dor Docker. But using Docker Swarm do we need Kubernets at all. We have known that Kubernets have been dropping Docker for a long time, it has now happened. Using clustering with Kubernets we do ket more options but we also loose automtic load-balancing that we het with Swarm. Docker swarm is simple and easy to set up and all is inlcuded in the comminuty edition.

This video shows how you can create your Swarm mater and join nodes to your cluster. Try Docker Swarm today 🤍 Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.

Here is a quick demonstration on Docker Swarm getting started. Here are the commands I have used for this. For 1:1 Online Training please visit 🤍 docker-machine create driver virtualbox manager1 docker-machine ls docker-machine create driver virtualbox worker1 docker-machine create driver virtualbox worker2 docker-machine ls We have created the three vms Get into the manager node docker-machine ssh manager1 docker swarm init advertise-addr 192.168.99.100 Now on to the worker nodes docker-machine ssh worker1 docker swarm join token SWMTKN-1-2mk0akcfd6z66izhekap0ajhrf2p6398sqg3y1x8hngwxb3aap-dzfc4urwpuelj22fbdndxnhbt 192.168.99.100:2377 docker-machine ssh worker2 docker swarm join token SWMTKN-1-2mk0akcfd6z66izhekap0ajhrf2p6398sqg3y1x8hngwxb3aap-dzfc4urwpuelj22fbdndxnhbt 192.168.99.100:2377 Now we need to get into the manager node for all our remaining docker swarm commands! [MANAGER NODE] docker node ls docker service create \ name mynginx \ publish 8080:80 \ replicas 3 \ nginx docker service ls docker service ps mynginx Browse the server http://192.168.99.100:8080/ In order to confirm whihc nginx container is server let us make some changes to the index.html file in each of our node conatiners. [MANAGER NODE] we need to know the container ID using docker ps and use docker exec to get in docker exec -ti [CONTAINER_ID] bin/bash # echo "Server file served from Manager Node..." /usr/share/nginx/html/index.html Let us repeat this on the other two worker nodes. Let us browse and see which one is being served http://192.168.99.100:8080/ Ok this page is from the manager nodes ngnx conatiner. Let us drain this node from the service Sorry I am inside the container, let me exit to get back to the manager node prompt. [MANAGER NODE] docker service ps mynginx we have three nodes in our nginx service, let us drain the manager node from this. docker node update availability drain manager1 docker service ps mynginx yes it has been removed. Now let us refresh and see, yes now work1 is being served. We could also scale down or up the number of nodes in a docker swarm service. example.. $ docker service scale mynginx=2 $ docker service ps mynginx Also docker swarm built in load balancer will auto route the incoming requests to the containers. Let us refresh and see. Instead of worker 1 now worker 2 is serving the page. Finally in order to clean up our experiements all we need to do is to docker-machine rm manager1 worker1 worker2 All the three machines have been removed... yes our ssh session have terminated as well. Hope you like this docker swarm quick demo and please feel free give your valuable feedbacks. Thank you!

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?

Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual Docker host. It is powerful, highly scalable, and easy to use. Swarm maintainer and Docker Engineer Alexandre Belsic went in front of a whiteboard to give a high level introduction to how Swarm can be used. This is Part 1, the overview. Part 1 Overview: 🤍 Part 2 Discovery: 🤍 Part 3 Scheduling: 🤍 Part 4 High Availability: 🤍 Part 5 Networking: 🤍 Part 6 Volumes: 🤍 🤍 Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.

Kubernetes - 🤍 Kubernetes стал стандартом де-факто и вытеснил другие решения контейнеризации. Есть мнение, что технология сложна в управлении и мало доступна обычным людям. Swarm проще: его легче поднять. Но в нём не хватает много полезных фич: например, авторизации в кластере, встроенных балансеров. Уйти или остаться? Мы рассмотрим оба решения, Docker Swarm и Kubernetes — и разберемся, почему вам лучше перейти на K8s или наоборот, остаться на Swarm.

Swarm is native clustering for the Docker. When the Docker Engine runs in swarm mode, manager nodes implement the Raft Consensus Algorithm to manage the global cluster state.The reason why Docker swarm mode is using a consensus algorithm is to make sure that all the manager nodes that are in charge of managing and scheduling tasks in the cluster, are storing the same consistent state. LAB Setup In this LAB we are going to create a SWARM cluster with single manager and 02 worker nodes. Operating System : CentOS 7.3 x86_64 Platform : Vagrant Machines Manager Node : manager | 192.168.1.100/24 Worker Node 1 : node-1 | 192.168.1.101/24 Worker Node 2 : node-2 | 192.168.1.102/24 Watch the video for more details :
Cette vidéo va nous permettre de découvrir les premières étapes d'initialisation d'un cluster swarm. Nous y découvrons le rôle de manager au sein du cluster. Un swarm peut disposer d'un ou de plusieurs managers actif ou non. Ces managers gèrent les tâches de gestion du cluster et peuvent éventuellement porter des conteneurs.

Play-With-Docker.com est un superbe outil que la team docker nous met à disposition. Il permet de disposer gratuitement de machines virtuelles en ligne. Ces machines disposent par ailleurs de docker d'installer dessus. Vous pouvez instancier de nombreuses machines et bénéficier d'un réseau entre elles... c'est donc un très bon moyen pour découvrir docker swarm. Entre outre ces machines sont également accessibles via une connexion ssh non sécurisée.
