From 2dd67e62d0bad5d05699278eca8a4a9875b9a591 Mon Sep 17 00:00:00 2001 From: Erik Reinert <4638629+erikreinert@users.noreply.github.com> Date: Sun, 14 Jul 2024 14:15:45 -0700 Subject: [PATCH] feat(terraform): add GitHub configuration to Terraform setup - Introduced GitHubConfig and GitHubConfigAction structs to manage GitHub-specific settings. - Updated TerraformConfig to include GitHubConfig. - Added functions NewGitHubConfigAction and NewGitHubConfig to initialize GitHub configurations. - Modified GitHub Actions workflow template to utilize the new GitHub configuration settings. - Conditional steps for setting up Nix and deploy keys based on GitHubConfigAction. - Environment variables and runner configuration are now dynamically set based on GitHubConfig. --- internal/config/terraform.go | 28 ++++ .../.github__workflows__terraform.yaml | 137 +++++++++++------- 2 files changed, 110 insertions(+), 55 deletions(-) diff --git a/internal/config/terraform.go b/internal/config/terraform.go index ad33cdd..5c511f2 100644 --- a/internal/config/terraform.go +++ b/internal/config/terraform.go @@ -8,6 +8,17 @@ import ( const TerraformName = "terraform" +type GitHubConfigAction struct { + SetupDeployKey bool `json:"setupDeployKey,omitempty" yaml:"setupDeployKey,omitempty"` + SetupNix bool `json:"setupNix,omitempty" yaml:"setupNix,omitempty"` +} + +type GitHubConfig struct { + Action GitHubConfigAction `json:"action,omitempty" yaml:"action,omitempty"` + Env map[string]string `json:"env,omitempty" yaml:"env,omitempty"` + RunsOn string `json:"runsOn,omitempty" yaml:"runsOn,omitempty"` +} + type TerraformConfigRole struct { PlanARN string `json:"planArn,omitempty" yaml:"planArn,omitempty"` ApplyARN string `json:"applyArn,omitempty" yaml:"applyArn,omitempty"` @@ -15,6 +26,7 @@ type TerraformConfigRole struct { type TerraformConfig struct { Config + GitHub GitHubConfig `json:"github,omitempty" yaml:"github,omitempty"` Nix NixConfig `json:"nix,omitempty" yaml:"nix,omitempty"` Region string `json:"region,omitempty" yaml:"region,omitempty"` Role TerraformConfigRole `json:"role,omitempty" yaml:"role,omitempty"` @@ -22,6 +34,21 @@ type TerraformConfig struct { Providers []string `json:"providers,omitempty" yaml:"providers,omitempty"` } +func NewGitHubConfigAction() GitHubConfigAction { + return GitHubConfigAction{ + SetupDeployKey: false, + SetupNix: true, + } +} + +func NewGitHubConfig() GitHubConfig { + return GitHubConfig{ + Action: NewGitHubConfigAction(), + Env: map[string]string{}, + RunsOn: "ubuntu-latest", + } +} + func NewTerraformConfigRole(name string) TerraformConfigRole { return TerraformConfigRole{ ApplyARN: fmt.Sprintf("arn:aws:iam::677459762413:role/altf4llc-gha-%s-apply", name), @@ -32,6 +59,7 @@ func NewTerraformConfigRole(name string) TerraformConfigRole { func NewTerraformConfig(c Config) TerraformConfig { return TerraformConfig{ Config: c, + GitHub: NewGitHubConfig(), Nix: NewNixConfig(), Region: "us-west-2", Role: NewTerraformConfigRole(c.Name), diff --git a/internal/templates/templates/terraform/.github__workflows__terraform.yaml b/internal/templates/templates/terraform/.github__workflows__terraform.yaml index 330a946..03643e6 100644 --- a/internal/templates/templates/terraform/.github__workflows__terraform.yaml +++ b/internal/templates/templates/terraform/.github__workflows__terraform.yaml @@ -1,3 +1,4 @@ +{{- $envLength := len .GitHub.Env -}} name: terraform on: @@ -16,83 +17,109 @@ env: jobs: check: -
