July 21st concluded our most recent development sprint on the Canonical Distribution of Kubernetes (CDK). Here’s a look at what we did.
Fixes and Improvements
Check out the full list on GitHub. Here are some notables:
- Made load balancer port configurable
- Changed default
/16CIDR to allow more NodePort IP addresses
- Fixed etcd snapshot action
- Increased default worker node constraints to 4 cpu, 4GB RAM
- Added a test to ensure dashboard is operational after deploy
- Added a test for the built-in microbot example
- Added a Jenkins job to test master charms with stable snaps. When this is green it means we can release whatever new fixes/features we have queued up in the charms, giving us the confidence to do more frequent releases.
- Calico spike. We want to provide a CDK + Calico deployment option that works on any cloud, just like our CDK + Flannel option. We’ve decided to go with a Calico-on-Flannel (Canal) approach initially. Canal combines the network policy enforcement of Calico with the ease-of-deployment of Flannel. Work begins in the current sprint!
- RBAC spike. We mapped out the work necessary for enabling RBAC via charm config. Work begins in the current sprint!
- Updated the canonical-kubernetes-elastic bundle. This bundle has been added to our Jenkins build process and updated with the latest 1.7 charms.
