+ isolate etcd on the master node by letting it listen only on loopback
+ enabling kubelet on master and taint master with NoSchedule
The reason for the latter is that flannel requires all nodes to be "registered"
in the cluster in order to setup the cluster network. This means that the
kubelet is needed even at nodes on which we don't plan to schedule anything.
- All kubernetes components have been seperated into different files
- All TLS-enabled ports have been deprecated and disabled by default
- EasyCert option added to support automatic cluster PKI-bootstrap
- RBAC has been enforced for all cluster components by default
- NixOS kubernetes test cases make use of easyCerts to setup PKI
VMs were starving, many of the daemons were unable to complete their
tasks resulting in tests failures.
Turned off verbose output from k8s components as it consumes even more resources, and useful error messages actually drown in debug-clutter
* Fix reference CNI plugins
* The plugins were split out of the upstream cni repo around version
0.6.0
* Fix RBAC and DNS tests
* Fix broken apiVersion fields
* Change plugin linking to look in ${package}/bin rather than
${package.plugins}
* Initial work towards a working e2e test
* Test still fails, but at least the expression evaluates now
