<p>I need to make a decision for container orchestration , and needed help in finding out limitation in real world scenarios that can occur using docker swarm over kubernetes, if anyone ever faced any such limitation please suggest. </p>

<p><em>The containers cluster may reach a value of approx 50-100 containers.</em>  </p>

<p>Docker swarm is young and there are a lot of features introduced relatively quickly. This however causes more issues and open "serious" bugs. For a production system that should be up 100% that might be an issue. I personally experienced <a href="https://github.com/moby/moby/issues/31698" rel="nofollow noreferrer">a bug</a> that made it impossible to start new containers because they were assigned an IP that is already taken. This forced me to shut down my swarm (it's a dev system so I didn't mind too much).</p>

<p>I suggest having a look at <a href="https://github.com/moby/moby/issues?q=is%3Aopen+label%3Aarea%2Fswarm+sort%3Acomments-desc" rel="nofollow noreferrer">the most commented swarm bugs/issues</a> in github.</p>
