* Replace v0.11 bracket type hints with Terraform v0.12 list expressions
* Use expression syntax instead of interpolated strings, where suggested
* Update bare-metal tutorial
* Define `clc_snippets` type constraint map(list(string))
* Define Terraform and plugin version requirements in versions.tf
* Require matchbox ~> 0.3.0 to support Terraform v0.12
* Require ct ~> 0.3.2 to support Terraform v0.12
* Azure only allows `eviction_policy` to be set for Low priority VMs.
Supporting Low priority VMs meant when Regular VMs were used, each
`terraform apply` rolled workers, to set eviction_policy to null.
* Terraform v0.12 nullable variables fix the issue and plan does not
produce a diff

* Use expression syntax instead of interpolated strings, where suggested
* Update Azure tutorial and worker pools documentation
* Define Terraform and plugin version requirements in versions.tf

* Replace v0.11 bracket type hints with Terraform v0.12 list expressions
* Use expression syntax instead of interpolated strings, where suggested
* Update DigitalOcean tutorial documentation
* Define Terraform and plugin version requirements in versions.tf
* Require digitalocean ~> v1.3 to support Terraform v0.12
* Require ct ~> v0.3.2 to support Terraform v0.12
* This change affects users who use worker pools on AWS, GCP, or
Azure with a Container Linux derivative
* Rename worker pool modules' `count` variable to `worker_count`,
because `count` will be a reserved variable name in Terraform v0.12
* Fix to remove a trailing slash that was erroneously introduced
in the scripting that updated from v1.14.1 to v1.14.2
* Workaround before this fix was to re-run `terraform init`
* Introduce "calico" as a `networking` option on Azure and DigitalOcean
using Calico's new VXLAN support (similar to flannel). Flannel remains
the default on these platforms for now.
* Historically, DigitalOcean and Azure only allowed Flannel as the
CNI provider, since those platforms don't support IPIP traffic that
was previously required for Calico.
* Looking forward, its desireable for Calico to become the default
across Typhoon clusters, since it provides NetworkPolicy and a
consistent experience
* No changes to AWS, GCP, or bare-metal where Calico remains the
default CNI provider. On these platforms, IPIP mode will always
be used, since its available and more performant than vxlan
* DigitalOcean clusters must secure copy a kubeconfig to
worker nodes, but Terraform could decide to try copying
before firewall rules have been added to allow SSH access.
* Add an explicit dependency on adding firewall rules first
* Change flannel port from the kernel default 8472 to the
IANA assigned VXLAN port 4789
* Update firewall rules or security groups for VXLAN
* Why now? Calico now offers its own VXLAN backend so
standardizing on the IANA port will simplify config
* https://github.com/coreos/flannel/blob/master/Documentation/backends.md#vxlan
* Remove Fedora Atomic tutorials and docs from the Typhoon
site to make it more obvious the modules are deprecated
* Continue to serve Fedora Atomic materials via direct link
for some time
* This reverts commit 6e5d66cf66
* kube-state-metrics v1.6.0-rc.0 fires KubeDeploymentReplicasMismatch
alerts where its own Deployment doesn't have replicas available,
(kube_deployment_status_replicas_available) even though all replicas
are available according to kubectl inspection
* This problem was present even with the CSR ClusterRole fix
(https://github.com/kubernetes/kube-state-metrics/pull/717)
If no region is set at the Google provider level, Terraform fails to
create the google_compute_target_pool.workers resource and complains
with "Cannot determine region: set in this resource, or set provider-level 'region' or 'zone'."
This commit fixes the issue by explicitly setting the region for the
google_compute_target_pool.workers resource.
* Add ability to load balance TCP/UDP applications (e.g. NodePort)
* Output the load balancer ID as `loadbalancer_id`
* Output `worker_security_group_name` and `worker_address_prefix`
for extending firewall rules
