[che-dev] Workspace sidecars resilience and logs in Che 7

[Oleksandr Garagatyi <ogaragat@xxxxxxxxxx>]

Hello. On the last Che community meeting, we were discussing a couple of features of workspaces in Che 7:

- restart of workspace containers when the main process gets killed for some reason or exits 

- an ability to collect all workspaces containers logs using Logstash or Fluentd like services

Here is a demo that shows that all the tools in Che 7 workspace run as sidecars and put their logs to container output which allows us to collect those logs:

And here is a demo of what is happening when a workspace sidecar container gets killed on an example of Theia sidecar. This particular example is especially cool because Theia restores gracefully in such a case and provides great UX:
