You do not need to learn much about swarm to deploy your first stack because you'll use a Docker Compose file.
Docker Swarmĭocker swarm on the other hand is simpler than K8s. You only need to inform how many worker nodes do you want and deploy your containers. Because of this a lot of datacenter created your own service based on the K8s. You'll need to maintain not only your container but the Kubernetes infrastructure itself.

However it is not so easy to install and maintain a complete functional Kubernetes cluster from scratch. Deploy a container, claim for a volume or publish it to external world is pretty simple based on Yaml files. With K8s we can autoscale our containers and host machines based on its internal monitoring. It is also why almost all hosting providers like Google, AWS, Azure, IBM, Digital Ocean, etc have your own K8s implementation. It means that each feature can use the native K8s implementation or can be overridden by some other set of tools to implement a specific feature. Kubernetes (K8s) is an opensource system for container orchestration with a complete set of plugable features like monitoring, ingress, volumes and others using a standardize API. If you are interested to know a little more about Container Orchestration and K8s you can take a look at the presentation I did for the Google Developer Day Winnipeg Docker Swarm vs Kubernetes Kubernetes They will guarantee that the deploy was sucessful and if everything fails you'll know why. It does not matter if I am using Kubernetes, Amazon ECS, Docker Swarm or any other. When I am deploying a container using a container orchestrator I just need to inform the image, the number of containers and resources it needs to run and the orchestrator will create the required instances and allocate the resources for you. "a system for automating deployment, scaling, and management of containerized applications." However when we have to deploy a hundred or a thousands containers in a big cluster of machines and each container needs some type of resources then Container Orchestration makes sense.
If we are deploying a few containers in the same machine there is no reason to even know what is container orchestration.
I developed this infrastructure and I am using for myself in my projects.įirst let's talk about some very basic concepts Container Orchestration
Docker swarm vs kubernetes 2019 how to#
In this article I'll discuss about some concepts and after that I'll demonstrate how to create a complete Docker Swarm infrastructure using Terrascript with a very basic Volume Claim without any special plugin and a very basic Ingress controller using HAProxy and with a container auto-discovery and dynamic configuration. However, docker swarm does not have any datacenter are implementing it and are creating some of structure ready to go as K8s has. Most of important data centers (Google, AWS, Azure, Oracle, IBM, Digital Ocean, etc) already implemented some sort of Kubernetes as a Service make it easy its adoption. Because of this it miss a lot of features that Kubernetes already implemented by default. Before someone blame me about why I am not using Kubernetes, AWS ECS, Mesos or anything but Swarm the answer is simple: Docker Swarm is an inexpensive and very simple thin orchestrator.
