Easy cluster solution for your platform **Rating:** 4.5/5.0 stars **Reviewed by:** César G. | Senior Software Development Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** October 04, 2021 **What do you like best about Docker Swarm?** Zero-downtime deployments are straightforward to configure in the service. The swarm will not send traffic to the updated container until it is healthy and will not shut down the old one until the pending request has finished. Also, if a service doesn't start correctly (health check failure), Docker is smart enough to keep the previous version running. The configuration file (docker-compose.yml) is idempotent, so only the changes to the service are applied when deployed. I tried to learn k8s, but it had many moving parts that make debugging very hard when something goes wrong, compared to Docker Swarm, where everything uses the same daemon in every node, so the log is centralized. I love that the service description in the config file can be straightforward because many things are implicit by design (like network/volume names) or easier to see. For example, opening a port for a container in every node can be done in a single line. **What do you dislike about Docker Swarm?** Over the years, I found some limitations when deploying services on the Swarm. Recently they are solved, but most have opened issues in GitHub for many years. Some examples: * Opening a shell to a container requires locating the node where the service is running, then logging into that node. * Cannot access special devices (like a GPU) from my containers running in Swarm mode without hacks. * I cannot update secret/config in services without changing their referenced name in the service config. I had to create a tool to overcome this limitation. There are tools that help some pain points (like Portainer), but one shouldn't need to rely on 3rd party utilities to handle the software. When testing Kebernetes, I found that most of these issues are solved or don't exist in k8s. **Recommendations to others considering Docker Swarm:** Even when there is not much development going on Docker Swarm currently, it is way easier to configure and administrate compared to Kubernetes. I recommend switching to k8s only if you have the personnel and time to handle it, or you will be overwhelmed with too many features. **What problems is Docker Swarm solving and how is that benefiting you?** We use Docker Swarm to deploy hundred of services and update them continuously without having to interrupt the service to our customers. We can launch new web services in minutes without even having to log in to our servers since Swarm can provide the info about all of our services to our reverse proxy in real time and configure them automatically. ### 13. Dicker swarm to manage containers reviewing **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** July 16, 2022 **What do you like best about Docker Swarm?** It's easy to setup a cluster with very minimum things. It gives flexibility to setup ,Routing and things in ingress very easy. It makes orchestration easy way to production ready. **What do you dislike about Docker Swarm?** I also used kubernetes so observed some differences like docker swarm need to improve document, networking compatibilities and health checking .It was mess sometimes when I were using. **What problems is Docker Swarm solving and how is that benefiting you?** It's making orchestration little bit ready to use in very short time. Quick configuration scalling. Docker swarm makes Easiness of load balancing and volume mounting. ### 14.

Docker Swarm review by Prabu **Rating:** 4.0/5.0 stars **Reviewed by:** Prabu S. | Developer, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** September 08, 2021 ### 16. best orchestrator tool of its time **Rating:** 4.5/5.0 stars **Reviewed by:** Jasmeet singh V. | Software Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** October 08, 2021 **What do you like best about Docker Swarm?** As we all know, Docker is a containerized engine that we use to create and manage containers. To automate processes, we use Docker Swarm, which can be considered similar to or an older version of Kubernetes. After Kubernetes entered the market, the value of Docker Swarm decreased, but in some scenarios, Docker Swarm is still preferred. When we talk about orchestration, it means coordinating like a musician or singer orchestrates their group, deciding when the drummer should play, what the guitarist will play, and so on. In a containerized environment, it is used to orchestrate images. If the images stop or crash, what is the policy to revive them, and how to create duplication or replication of them? This is how it is used and helps automate the handling of images for a DevOps person. **What do you dislike about Docker Swarm?** We can only orchestrate Docker images, but in Kubernetes, we can take any containerized engine and orchestrate them all together. **What problems is Docker Swarm solving and how is that benefiting you?** Before using Kubernetes, our project was using Docker Swarm to orchestrate our product images, but after the introduction of Kubernetes, we switched to Kubernetes. ### 17.
