Kubernetes SidecarContainers feature is merged
On the one hand, great.<p>The other hand, one of the main criticisms of Kubernetes is that it has no composition or orchestration capabilities. It's great about defining pieces of state, but managing blocks of state & multiple things at once is left almost entirely to external tools.<p>The ability to compose &sequence multiple containers feels like a very specific example of a much broader general capability. There's bedevilling infinite complexity to trying to figure out a fully expressive state of state management system - I get why refining a couple specialized existing capabilities is the way - but it does make me a little sad to see a lack of appetite for the broader crosscutting system problem at the root here.
