Upgrade story with deployments
  1. Deployments are not available in v1 or server version 1.2, they are available as a part of v1extensions, basically we can't do it now
  2. Replicaiton controllers are not compatible with deployments. only replica sets
  3. Deployments support releases and rollbacks, canary and rolling updates
  4. Horizontal pod scalar again works on replica sets but scales the pods according to CPU utilization
  • Deployments are good only if you are thinking of doing a roll back.
  • For our usecase where every thing is an RC1 and just thinking about updating the exiting image for an RC , kubectl apply/edit RC is sufficient, unless we are not looking for kubectl rollback --release=<>
  • Coming to Apps, thoerically deployments adds features like releases to an App. Also if we can treat every build as a release then basically let the builder deploy an App as deployment,

Cluster of N nodes
Runs 3 or more deis installs with different namesapces
So already componenets are running with same RC but in different namepsaces
Now A queue of test exists
1. Round robin these queue of tests to the exisiting deis install of differents namespaces
2. Each test builds a respective image and update the Image in the RC of the assigned namesapce
