Server and Analyzer should expose an HTTP-level endpoints that can be used as kubernetes life-probes. As [discussed](https://github.com/src-d/minutes/pull/309/files#diff-d707b85ec18906cb2d5bedb7373d595aR47), at this point probes could check accessibility of it's dependencies like DB, Bblfsh, etc. Eventually, it would be really nice for such checks to become more complex and execute some basic scenarios and verify them pass (like a simple live unit-tests). For now: - [ ] check what kind of life probes k8s supports/recomends - [ ] add endpoints to Server and Dummy analyzer - [x] update charts \w life probes
