BREAKING CHANGES: We now decided to remove `random_pet` resources in Managed Node Groups (MNG). Those were used to recreate MNG if something change and also simulate the newly added argument `node_group_name_prefix`. But they were causing a lot of troubles. To upgrade the module without recreating your MNG, you will need to explicitly reuse their previous name and set them in your MNG `name` argument. Please see [upgrade docs](https://github.com/terraform-aws-modules/terraform-aws-eks/blob/master/docs/upgrades.md#upgrade-module-to-v1700-for-managed-node-groups) for more details.
BREAKING CHANGES: We remove the dependency on the deprecated `hashicorp/template` provider and use the Terraform built in `templatefile` function. This will broke some workflows due to previously being able to pass in the raw contents of a template file for processing. The `templatefile` function requires a template file that exists before running a plan.
NOTES: Using the [terraform-aws-modules/http](https://registry.terraform.io/providers/terraform-aws-modules/http/latest) provider is a more platform agnostic way to wait for the cluster availability than using a local-exec. With this change we're able to provision EKS clusters and manage the `aws_auth` configmap while still using the `hashicorp/tfc-agent` docker image.
Additional support for Terraform v0.13 and aws v3!
- The update to the vpc module in examples was, strictly speaking, unnecessary but it adds the terraform block with supported versions.
- Update for iam module in the example was very necessary to support new versions
- Workaround for "Provider produced inconsistent final plan" when creating ASGs at the same time as the cluster. See https://github.com/terraform-providers/terraform-provider-aws/issues/14085 for full details.
- Blacklist 0.13.0 as it was too strict when migrating from aws v2 to v3 about dropped attributes.
NOTES: Addition of the IMDSv2 metadata configuration block to Launch Templates will cause a diff to be generated for existing Launch Templates on first Terraform apply. The defaults match existing behaviour.
* Create kubeconfig with non-executable permissions
Kubeconfig does not really need to be executable, so let's not create it with executable bit set.
* Bump tf version
* Remove template_file for generating kubeconfig
Push logic from terraform down to the template. Makes the formatting
slightly easier to follow
* Remove template_file for generating userdata
Updates to the eks_cluster now do not trigger recreation of launch
configurations
* Remove template_file for LT userdata
* Remove template dependency
BREAKING CHANGE: The terraform-aws-eks module now require at least kubernetes `1.11.1`. This may cause terraform to fail to init if users have set version = "1.10" like we had in the examples.
* wait for cluster to respond before creating auth config map
* adds changelog entry
* fixup tf format
