Migrate Google Cloud module Terraform v0.11 to v0.12 * Replace v0.11 bracket type hints with Terraform v0.12 list expressions * Use expression syntax instead of interpolated strings, where suggested * Update Google Cloud tutorial and worker pools documentation * Define Terraform and plugin version requirements in versions.tf * Require google ~> 2.5 to support Terraform v0.12 * Require ct ~> 0.3.2 to support Terraform v0.12 2019-05-28 06:14:25 +02:00			`# Terraform version and plugin versions`

Adopt Terraform v0.12 templatefile function * Update terraform-render-bootstrap module to adopt the Terrform v0.12 templatefile function feature to replace the use of terraform-provider-template's `template_dir` * Require Terraform v0.12.6+ which adds `for_each` Background: * `template_dir` was added to `terraform-provider-template` to add support for template directory rendering in CoreOS Tectonic Kubernetes distribution (~2017) * Terraform v0.12 introduced a native `templatefile` function and v0.12.6 introduced native `for_each` support (July 2019) that makes it possible to replace `template_dir` usage 2019-11-13 23:09:34 +01:00			`required_version = "~> 0.12.6"`

Allow terraform-provider-google v3.x plugin versions * Typhoon Google Cloud is compatible with `terraform-provider-google` v3.x releases * No v3.x specific features are used, so v2.19+ provider versions are still allowed, to ease migrations 2020-01-11 22:58:23 +01:00			`google = ">= 2.19, < 4.0"`
Use strict mode for Container Linux Configs * Enable terraform-provider-ct `strict` mode for parsing Container Linux Configs and snippets * Fix Container Linux Config systemd unit syntax `enable` (old) to `enabled` * Align with Fedora CoreOS which uses strict mode already 2020-06-10 07:38:32 +02:00			`ct = "~> 0.4"`
Use GCP region_instance_group_manager version block format * terraform-provider-google v2.19.0 deprecates `instance_template` within `google_compute_region_instance_group_manager` in order to support a scheme with multiple version blocks. Adapt our single version to the new format to resolve deprecation warnings. * Fixes: Warning: "instance_template": [DEPRECATED] This field will be replaced by `version.instance_template` in 3.0.0 * Require terraform-provider-google v2.19.0+ (action required) 2019-11-14 02:31:11 +01:00			`template = "~> 2.1"`
