Docker is an open source project that automates the deployment of applications using containers, providing an additional layer of abstraction and automation on top of Linux This playground provides a personalised sandboxed environment for you to learn and explore Docker. A Docker image is a readonly template used to build containers Images are used to store and ship applications A Docker service allows containers to be scaled across multiple Docker daemons The result is known as a swarm, a set of cooperating daemons that communicate through the Docker API. You can use Docker Desktop for Mac or Windows to test singlenode features of swarm mode, including initializing a swarm with a single node, creating services, and scaling services.

Standalone Docker Swarm >= 123 (NOTE Use of Standalone Docker Swarm is being discouraged since the introduction of builtin Swarm Mode in Docker While older versions of Portainer had support for Standalone Docker Swarm, Portainer 1170 and newer do not support it However, the builtin Swarm Mode of Docker is fully supported). View docker swarm handsontxt from IT DESIGN at IIT Kanpur = WORKING WITH SECRETS docker swarm init echo "test" docker secret create mysecret docker secret ls docker service create. Docker Swarm service discovery architecture The Docker Swarm service discovery contains 3 different roles nodes, services, and tasks The first role, nodes, represents the hosts that are part of the Swarm It can be used to automatically monitor the Docker daemons or the Node Exporters who run on the Swarm hosts.

Docker Swarm is basically a cluster of physical or virtual machines called nodes which run docker containers separately and you can configure all these nodes to join a cluster managed by the master node called the swarm manager It is an orchestration tool which allows you to manage multiple Docker Containers deployed on different machines.
