Docker is great for when you would want to use a VM for any given application, but don't need the overhead of the whole OS. Docker containers use very little computing resources, boot up very quickly, and are very easy to set up. An instance where Docker may not be appropriate would be for an application that requires good security. If in this situation, a true VM would probably be your best bet.
RubyGems is a great packaging library primarily because of its verbose logging information and easy to navigate system architecture. We've dealt with artifactory systems in the past for Java and JavaScript, and RubyGems just makes it a lot easier to handle the packaging and deployment of our reusable libraries. We've noticed in the past that there are times where (if all 200+ teams) are releasing at a similar time that publishing the gems can lag, but that's fairly rare.
Docker has a bit of a learning curve, and it takes some time to become familiar with the tooling and syntax. Transitioning an existing architecture to docker can represent a significant investment.
Docker attempts to provide some level of cross-host container orchestration via swarm, but it falls short of third-party solutions like kubernetes.
We occasionally run into stability issues when the docker daemon is subjected to high load (many applications starting/stopping frequently). In these cases, docker hangs and we have to restart or replace the node.
Docker's CLI has a lot of options, and they aren't all intuitive. And there are so many tools in the space (Docker Compose, Docker Swarm, etc) that have their own configuration as well. So while there is a lot to learn, most concepts transfer easily and can be learned once and applied across everything.
The community support for Docker is fantastic. There is almost always an answer for any issue I might encounter day-to-day, either on Stack Overflow, a helpful blog post, or the community Slack workspace. I've never come across a problem that I was unable to solve via some searching around in the community.
RubyGems has strong community support and finding issues to errors is as simple as searching for the error message you're receiving (but usually the error is clear enough without having to bother with that). Honestly, the framework is simple enough that support isn't needed much, but it has been helpful to us in the past when we have needed it.
I have not used any other software as a container management solution. Its containerized apps allow the usage of less memory, thus they start and shut down very fast. This tool is helping the enterprise software to work quickly against the changing conditions thus offers great scaling by simultaneously allowing me to meet the demands, which also leads to easy implementation of the strategies.
RubyGems is easier to use and to troubleshoot issues overall. Sometimes when troubleshooting in other systems errors are masked and it takes a trained eye or a lot of time searching through Google trying to find out what it really means. RubyGems is very verbose and allows for quick troubleshooting of any deployment problems.
We are able to try things very quickly compared to before. If you need to debug it, changes on X/Y/Z will have an impact on the way your app works, and changing libraries or configurations of the environment easily can improve your development cycles.
In case someone new arrives, the onboarding is pretty easy thanks to Docker. We have tried many configs and images until we reached a point were we have what we want. We don't have to painfully do that again for every new user. We just send him the image.
