Very cool project!
I was the founder of a school training software engineers, we had an infrastructure track that got a lot of our students to land SRE positions. When asking employers for feedback about our grads, one feedback kept coming: they lack experience when it comes to troubleshooting.
So I went on a quest to simulate that infra debugging while in an academic context.
I came up with the idea of giving students broken servers. I used Docker container and would setup a simple workload and mess it up with classic issues.
Needless to say students generally did not like it :) debugging isn’t fun. But it did help a lot.
