[v1.7.0] - 2018-09-??]

Added

A useful addition (slam dunk, @self 🔥)
Worker groups can be created with a specified IAM profile. (from @laverya)

Changed

A subtle but thoughtful change. (Boomshakalaka, @self 🏀)
fix default worker subnets not working (by @erks)
fix default worker autoscaling_enabled not working (by @erks)
Cosmetic syntax changes to improve readability. (by @max-rocket-internet)
add protect_from_scale_in to solve issue #134 (by @kinghajj)

[v1.6.0] - 2018-09-04]

Added

add support for amazon-eks-node-* AMI with bootstrap script (by @erks)
expose kubelet_extra_args worker group option (replacing kubelet_node_labels) to allow specifying arbitrary kubelet options (e.g. taints and labels) (by @erks)
add optional input worker_additional_security_group_ids to allow one or more additional security groups to be added to all worker launch configurations - #47 (by @hhobbsh @mr-joshua)
add optional input additional_security_group_ids to allow one or more additional security groups to be added to a specific worker launch configuration - #47 (by @mr-joshua)

Changed

allow a custom AMI to be specified as a default (by @erks)
bugfix for above change (by @max-rocket-internet)
Breaking change Removed support for eks-worker-* AMI. The cluster specifying a custom AMI based off of eks-worker-* AMI will have to rebuild the AMI from amazon-eks-node-*. (by @erks)
Breaking change Removed kubelet_node_labels worker group option in favor of kubelet_extra_args. (by @erks)

[v1.5.0] - 2018-08-30]

Added

add spot_price option to aws_launch_configuration
add enable_monitoring option to aws_launch_configuration
add t3 instance class settings
add aws_iam_service_linked_role for elasticloadbalancing. (by @max-rocket-internet)
Added autoscaling policies into module that are optionally attached when enabled for a worker group. (by @max-rocket-internet)

Changed

Breaking change Removed workstation_cidr variable, http callout and unnecessary security rule. (by @dpiddockcmp) If you are upgrading from 1.4 you should fix state after upgrade: terraform state rm module.eks.data.http.workstation_external_ip
Can now selectively override keys in workers_group_defaults variable rather than callers maintaining a duplicate of the whole map. (by @dpiddockcmp)

[v1.4.0] - 2018-08-02]

Added

manage eks workers' root volume size and type.
workers_asg_names added to outputs. (kudos to @laverya)
New top level variable worker_group_count added to replace the use of length(var.worker_groups). This allows using computed values as part of worker group configs. (complaints to @laverya)

[v1.3.0] - 2018-07-11]

Added

New variables map_accounts, map_roles and map_users in order to manage additional entries in the aws-auth configmap. (by @max-rocket-internet)
kubelet_node_labels worker group option allows setting --node-labels= in kubelet. (Hat-tip, @bshelton229 👒)
worker_iam_role_arn added to outputs. Sweet, @hatemosphere 🔥

Changed

Worker subnets able to be specified as a dedicated list per autoscaling group. (up top, @bshelton229 🙏)

[v1.2.0] - 2018-07-01]

Added

new variable pre_userdata added to worker launch configuration allows to run scripts before the plugin does anything. (W00t, @jimbeck 🦉)

Changed

kubeconfig made much more flexible. (Bang up job, @sdavids13 💥)
ASG desired capacity is now ignored as ASG size is more effectively handed by k8s. (Thanks, @ozbillwang 💇‍♂️)
Providing security groups didn't behave as expected. This has been fixed. (Good catch, @jimbeck 🔧)
workstation cidr to be allowed by created security group is now more flexible. (A welcome addition, @jimbeck 🔐)

[v1.1.0] - 2018-06-25]

Added

new variable worker_sg_ingress_from_port allows to change the minimum port number from which pods will accept communication (Thanks, @ilyasotkov 👏).
expanded on worker example to show how multiple worker autoscaling groups can be created.
IPv4 is used explicitly to resolve testing from IPv6 networks (thanks, @tsub 🙏).
Configurable public IP attachment and ssh keys for worker groups. Defaults defined in worker_group_defaults. Nice, @hatemosphere 🌂
worker_iam_role_name now an output. Sweet, @artursmet 🕶️

Changed

IAM test role repaired by @lcharkiewicz 💅
kube-proxy restart no longer needed in userdata. Good catch, @hatemosphere 🔥
worker ASG reattachment wasn't possible when using name. Moved to name_prefix to allow recreation of resources. Kudos again, @hatemosphere 🐧

[v1.0.0] - 2018-06-11]

Added

security group id can be provided for either/both of the cluster and the workers. If not provided, security groups will be created with sufficient rules to allow cluster-worker communication. - kudos to @tanmng on the idea ⭐
outputs of security group ids and worker ASG arns added for working with these resources outside the module.

Changed

Worker build out refactored to allow multiple autoscaling groups each having differing specs. If none are given, a single ASG is created with a set of sane defaults - big thanks to @kppullin 🥨

[v0.2.0] - 2018-06-08]

Added

ability to specify extra userdata code to execute following kubelet services start.
EBS optimization used whenever possible for the given instance type.
When configure_kubectl_session is set to true the current shell will be configured to talk to the kubernetes cluster using config files output from the module.

Changed

files rendered from dedicated templates to separate out raw code and config from hcl
workers_ami_id is now made optional. If not specified, the module will source the latest AWS supported EKS AMI instead.

[v0.1.1] - 2018-06-07]

Changed

Pre-commit hooks fixed and working.
Made progress on CI, advancing the build to the final kitchen test stage before failing.

[v0.1.0] - 2018-06-07

Added

Everything! Initial release of the module.
added a local variable to do a lookup against for a dynamic value in userdata which was previously static. Kudos to @tanmng for finding and fixing bug #1!
