What is Docker Swarm?
Docker Swarm is a container orchestration platform that is used to manage and schedule multiple Docker containers across a cluster of machines. Docker Swarm simplifies the deployment, scaling, and management of containerized applications. Here in Docker Swarm, there are mainly two types of nodes called manager and worker nodes. Managers manage the swarm and schedule containers across the cluster. Worker nodes help in executing the swarm services that are assigned to them. Services are defined with the desired state, which includes several replicas, exposed ports, networks, and storage resources. Docker Swarm allows configuration updates on services without any manual restarts. Swarm uses ingress to expose its services for external access. In summary, Docker Swarm simplifies the process of deploying and managing containerized applications. Its key features, like scalability, high availability, service discovery, load balancing, security, and easy deployment, make Docker Swarm a popular choice to orchestrate containerized applications efficiently.
Replicated VS Global Services In Docker Swarm
Docker Swarm is a container orchestration tool used to manage multiple Docker containers across a cluster. In this guide, I will first discuss what Docker Swarm is. Then I will discuss the difference between the key services, which are replicated services and global services. After this, I will walk you through the different steps to perform both replication service and global service in a Docker Swarm.
