# Docker Swarm

33 Hacker News commenters recommended Docker Swarm and 13 criticized it, November 2025 to November 2026. It was recommended in 10 of 13 months; owners who said how long report a median of 4 years (3 owners). It meets the Hacker Approved badge rule.

**Verdict:** Recommended as a simple way to run containers on a few servers, with rolling deployments and less complexity than Kubernetes; critics doubt its long-term future.

## Why people recommend it

- Runs reliably in production (8 comments): "Running Docker Swarm in production, can't really complain, at least for scales where you need a few steps up from a single node" ([source](https://news.ycombinator.com/item?id=45926544)) "I find Docker Swarm more reliable and easier to automate with a CI/CD pipeline than Compose" ([source](https://news.ycombinator.com/item?id=48027983)) "I'm still using it with not a single issue (except when is messes up the iptables rules)" ([source](https://news.ycombinator.com/item?id=45903806))
- Fits small to mid multi-server setups (6 comments): "I feel it's a solid tool for when you need some of the more complex multi server deployments" ([source](https://news.ycombinator.com/item?id=48013309)) "It's the right size for small-to-medium-size deployments with normal requirements." ([source](https://news.ycombinator.com/item?id=47039291)) "most mid-size companies would also be okay with Docker Swarm or Nomad" ([source](https://news.ycombinator.com/item?id=46794139))
- Simpler than Kubernetes (4 comments): "It's just lighter and less complicated, and for what I'm doing it more than satisfies my needs." ([source](https://news.ycombinator.com/item?id=47875307)) "I actually prefer Docker Swarm/Compose over K8s due to simplicity" ([source](https://news.ycombinator.com/item?id=48006662)) "compose/swarm is still light years easier than Kubernetes" ([source](https://news.ycombinator.com/item?id=49487562))
- Rolling deployments and zero downtime (3 comments): "On a single node it isn't really more complicated than compose, and you get scaling and rolling deployments." ([source](https://news.ycombinator.com/item?id=48027699)) "Docker swarm might fit better if you want seamless rollout deploys and quick rollbacks" ([source](https://news.ycombinator.com/item?id=48032414)) "you can do zero downtime deployment, simply with docker stack deploy -c stack.yml" ([source](https://news.ycombinator.com/item?id=48043153))

## What people warn about

- Uncertain long-term future (4 comments): "Swarm is easy to use but doesn't offer the extensibility, ecosystem, or long-term viability" ([source](https://news.ycombinator.com/item?id=45946091)) "It’s in a death spiral - not widely used so people aren’t incentivised to put time into it" ([source](https://news.ycombinator.com/item?id=47916512)) "It's so disappointing that Docker seems to slowly but steadily abandoning it." ([source](https://news.ycombinator.com/item?id=46155583))
- iptables and IPv6 problems (3 comments): "I'm still using it with not a single issue (except when is messes up the iptables rules)" ([source](https://news.ycombinator.com/item?id=45903806)) "not a single issue (except when is messes up the iptables rules)" ([source](https://news.ycombinator.com/item?id=45903762)) "it just doesn't seem to work (I've tried a lot) with ipv6" ([source](https://news.ycombinator.com/item?id=46147298))
- Released too early, incomplete (2 comments): "falls short based on things that needed to be fixed or finalized, that just never happened" ([source](https://news.ycombinator.com/item?id=50214370)) "it was released too soon with a buggy experience and at an incomplete state" ([source](https://news.ycombinator.com/item?id=46734566))
