1. The document discusses what Kubernetes vendors typically tell customers about Kubernetes versus what they do not tell customers. Vendors typically highlight benefits like automating deployment, scaling, and management of containerized applications but do not discuss challenges of adopting Kubernetes. 2. The discussion considers what questions customers should ask vendors to get a more complete picture of adopting Kubernetes, such as how ready their organization is and what might happen if adoption fails or is used in a different context. 3. It also examines what tools and topics vendors typically cover about Kubernetes versus those they do not, such as only focusing on successful case studies and not discussing reasons for failures or changing approaches over time.
