On serverfault it is possible to close questions due to insufficient research:
Requests for product, service, or learning material recommendations are off-topic because they attract low quality, opinionated and spam answers, and the answers become obsolete quickly. Instead, describe the business problem you are working on, the research you have done, and the steps taken so far to solve it.
According to me the following questions should be closed as there was insufficient research before asking the question:
How to create hybrid docker swarm mode cluster with multi-os application deployment?
How can I successfully debug a watcher? My watchers don't seem to do anything
What can explain ElasticSearch 2.4 not accepting to create watchers via curl?
