* Add `node_taints` variable to worker modules to set custom
initial node taints on cloud platforms that support auto-scaling
worker pools of heterogeneous nodes (i.e. AWS, Azure, GCP)
* Worker pools could use custom `node_labels` to allowed workloads
to select among differentiated nodes, while custom `node_taints`
allows a worker pool's nodes to be tainted as special to prevent
scheduling, except by workloads that explicitly tolerate the
taint
* Expose `daemonset_tolerations` in AWS, Azure, and GCP kubernetes
cluster modules, to determine whether `kube-system` components
should tolerate the custom taint (advanced use covered in docs)
Rel: #550, #663Closes#429
* Add experimental `arch` variable to Fedora CoreOS AWS,
accepting amd64 (default) or arm64 to support native
arm64/aarch64 clusters or mixed/hybrid clusters with
a worker pool of arm64 workers
* Add `daemonset_tolerations` variable to cluster module
(experimental)
* Add `node_taints` variable to workers module
* Requires flannel CNI and experimental Poseidon-built
arm64 Fedora CoreOS AMIs (published to us-east-1, us-east-2,
and us-west-1)
WARN:
* Our AMIs are experimental, may be removed at any time, and
will be removed when Fedora CoreOS publishes official arm64
AMIs. Do NOT use in production
