Absolutely same, I really want to get into it. I already tried to do so, but for some reason I was out of luck finding good resources for learning. Can someone recommend some great resources for beginners? TBH, would like a free resource. :D Beside that I want to get around HashiCorp tools, especially Vault for storing and Consul for service discovery.
