## Release notes for kops 1.17 series
(The kops 1.17 release has not been released yet; this is a document to gather
the notes prior to the release).
# Significant changes
* The default instance type for AWS is now t3.medium. This should provide better performance and reduced costs in clusters where the average CPU usage is low.
# Breaking changes
* Support for Docker versions 1.11, 1.12 and 1.13 has been removed because of the [dockerproject.org shut down](https://www.docker.com/blog/changes-dockerproject-org-apt-yum-repositories/). Those affected must upgrade to a newer Docker version.
* Terraform users on AWS may need to rename some resources in their state file in order to prepare for future Terraform 0.12 support. See Required Actions below.
* Please see the notes in the 1.15 release about the apiGroup changing from kops
to kops.k8s.io
* Since 1.16, a controller is now used to apply labels to nodes. If
you are not using AWS, GCE or OpenStack your (non-master) nodes may
not have labels applied correctly.
# Required Actions
* Terraform users on AWS may need to rename resources in their terraform state file in order to prepare for future Terraform 0.12 support.
Terraform 0.12 [no longer supports resource names starting with digits](https://www.terraform.io/upgrade-guides/0-12.html#pre-upgrade-checklist). In Kops, both the default route and additional VPC CIDR associations are affected. See [#7957](https://github.com/kubernetes/kops/pull/7957) for more information.
* The default route was named `aws_route.0-0-0-0--0` and will now be named `aws_route.route-0-0-0-0--0`.
* Additional CIDR blocks associated with a VPC were similarly named the hyphenated CIDR block with two hyphens for the `/`, for example `aws_vpc_ipv4_cidr_block_association.10-1-0-0--16`. These will now be prefixed with `cidr-`, for example `aws_vpc_ipv4_cidr_block_association.cidr-10-1-0-0--16`.
To prevent downtime, follow these steps with the new version of Kops:
```
kops update cluster --target terraform ...
terraform plan
# Observe any aws_route or aws_vpc_ipv4_cidr_block_association resources being destroyed and recreated
# Run these commands as necessary. The exact names may differ; use what is outputted by terraform plan
terraform state mv aws_route.0-0-0-0--0 aws_route.route-0-0-0-0--0
terraform state mv aws_vpc_ipv4_cidr_block_association.10-1-0-0--16 aws_vpc_ipv4_cidr_block_association.cidr-10-1-0-0--16
terraform plan
# Ensure these resources are no longer being destroyed and recreated
terraform apply
```
* Kubernetes 1.9 users will need to enable the PodPriority feature gate. This is required for newer versions of Kops.
To enable the Pod priority feature, follow these steps:
```
kops edit cluster
# Add the following section
spec:
kubelet:
featureGates:
PodPriority: "true"
```
* If either a Kops 1.17 alpha release or a custom Kops build was used on a cluster,
a kops-controller Deployment may have been created that should get deleted because it has been replaced with a DaemonSet.
Run `kubectl -n kube-system delete deployment kops-controller` after upgrading to Kops 1.17.0-alpha.2 or later.
# Deprecations
* Support for Kubernetes releases prior to 1.9 is deprecated and will be removed in kops 1.18.
* The `kops/v1alpha1` API is deprecated and will be removed in kops 1.18. Users of `kops replace` will need to supply v1alpha2 resources.
# Known Issues
* Kops 1.17.0-beta.1 included an update for AWS IAM Authenticator to 0.5.0.
This version fails to use the volume mounted ConfigMap causing API authentication issues for clients with aws-iam-authenticator credentials.
Any cluster with `spec.authentication.aws` defined according to the [docs](../authentication.md#aws-iam-authenticator) without overriding the `spec.authentication.aws.image` is affected.
The workaround is to specify the old 0.4.0 image with `spec.authentication.aws.image=602401143452.dkr.ecr.us-west-2.amazonaws.com/amazon/aws-iam-authenticator:v0.4.0`.
