No, technology is "docker." Containerisation is a family of technologies, but things like runc or - especially - LXC are quite different.
Thank you, I didn't realize LXC wasn't the only interface to cgroups used by Docker. TIL.
And projects like rkt don't exist in your world?
while it's been a while since my last brush with kubernetes, didn't they use kubectl?
So yeah... it's containerisation, not docker.
Rkt is functionally different enough from Docker to be called a different tech, and Kubernetes is, like, a totally different category. Are you also calling bicycles, cars and motorbikes the same technology, because they all use the technology called "wheel" somewhere?
