DeployStack

DeployStack is a one click solution for running Terraform projects for Google Cloud Platfom using Cloud Shell. It uses Open in Cloud Shell to guide users from a link to a series or questions to help them install a Terraform solution in their own Google Cloud Platform project space - prompting them to choose answers to questions like "What [datacenter] zone do you want to install in?" And presenting the options to guide them to pic the settings that are right for them.

For technical reasons, at this time, it is limited to working with github repos owned by Google Cloud Platform. You can see a list of DeployStack projects on cloud.google.com.

Authoring

Authoring information has been moved to deploystack/AUTHORING.MD.

This Codebase

This project is to centralize all of the tools and processes to get terminal interfaces for collecting information from users for use with DeployStack. Ultimately this codebase creates an executable that runs on Cloud Shell and works with other tools to drive the experience.

It's broken up into packages with different responsibilities:

deploystack

A top level package that ties together user i/o for the executable and passes information to the other packages

deploystack/config

The basic information schema that runs all of the other parts of the executable.

deploystack/gcloud

Communication with Google Cloud via the Go SDK to get things like region and zone lists

deploystack/github

Communication with Github for cloning and getting other metadata about projects

deploystack/terraform

Introspection of Terraform files for tooling and other metadata

deploystack/tui

A terminal user interface that is dynamically built based on config files rendered using BubbleTea , LipGloss, and Bubbles

Testing this Repo

In order to test the helper app in this repo, we need to do a fair amount of manipulation of projects and what not. The tests require a Service Account key json file. To faciliate this there is a script in tools/credsfile that will create a service account, give it the right access and service enablements, and export out a key file to use with testing.

This is not an offical Google product.

Functions

func AttemptRepo

func AttemptRepo(name, wd string) (string, github.Repo, error)

AttemptRepo will try to download a repo - only from GoogleCloudPlatform. If it fails, it will append "deploystack-" to the front of the requested name and try again.

func ContactCheck

func ContactCheck() gcloud.ContactData

ContactCheck checks the local file system for a file containg domain registar contact info

func ContactSave

func ContactSave(i interface{})

ContactSave writes a file containg domain registar contact info to disk if it exists

func DownloadRepo

func DownloadRepo(repo github.Repo, path string) (string, error)

DownloadRepo takes a name of a GoogleCloudPlatform repo or a GoogleCloudPlatform/deploystack-[name] repo, and downloads it into a unique folder name, and outputs that name

func Init

func Init(path string) (*config.Stack, error)

Init initializes a Deploystack stack by looking on teh local file system

func Precheck

func Precheck() error

Precheck handles the logic around switching working directories for multiple stacks in one repo

func UniquePath

func UniquePath(candidate string) string

UniquePath returns either the input candidate path if it does not exist, or a path like the input candidate with increasing nubmers appended to it until the ouput name is a path that does not exist

func WriteConfig

func WriteConfig(dir string, gh github.Repo) error

WriteConfig will drop a .deploystack folder with deploystack.yaml file for repos that do not have one.

Types

type Meta

type Meta struct {
	DeployStack config.Config
	Terraform   terraform.Blocks `json:"terraform" yaml:"terraform"`
	Github      github.Repo      `json:"github" yaml:"github"`
	LocalPath   string           `json:"localpath" yaml:"localpath"`
}

Meta is a datastructure that combines the Deploystack, github and Terraform bits of metadata about a stack.

func NewMeta

func NewMeta(path string) (Meta, error)

NewMeta allows project to point at local directories for info as well as pulling down from github

func (Meta) ShortName

func (m Meta) ShortName() string

ShortName retrieves the shortname of whatever we are calling this stack

func (Meta) ShortNameUnderscore

func (m Meta) ShortNameUnderscore() string

ShortNameUnderscore retrieves the shortname of whatever we are calling this stack replacing hyphens with underscores

func (Meta) Suggest

func (m Meta) Suggest() (config.Config, error)

Suggest will provide it's best guess of what the deploystack config should be based on the contents of the repo, including an existing deploystack config
