# Deploy to Google Compute Engine
Github action to simplify deploys to Google Compute Engine.
This action will...
1) Clone an existing instance template (using it as a base).
2) Update metadata config of the newly created instance template to run a startup script.
3) Tell the instance group manager to perform a rolling update with the new instance template.
## Prerequisites
Set up the following resources manually in the Cloud Console
or use a tool like [Terraform](https://www.terraform.io).
* Create a base [instance template](https://cloud.google.com/compute/docs/instance-templates/) to be cloned by this action.
* Create a managed [instance group](https://cloud.google.com/compute/docs/instance-groups/). Please note that currently **only regional instance groups** are supported.
* Create Service Account with Roles `Compute Admin` and `Service Account User` and export a new JSON key.
## deploy.yml
By default this action expects a `deploy.yml` in the root directory of the repository.
Here is an example:
```yaml
common:
labels:
gitsha: ${{GITHUB_SHA}}
deploys:
- name: my-app-deploy
region: us-central1
instance_group: my-app-instance-group
instance_template_base: my-app-instance-template-base
instance_template: my-app-${{GITHUB_RUN_NUMBER}}-${{GITHUB_SHA}}
cloud_init: cloud-init.yml # see example dir
labels: # will also have gitsha from common section
version: ${{APP_VERSION}}
tags:
- my-tag123
update_policy:
min_ready_sec: 30
delete_instance_templates_after: false
```

### Variables
Environment variables can be used in `deploy.yml`, `startup_script`, `shutdown_script` and `cloud_init` files.
The syntax is `${{FOO}}` and supports substring extraction, i.e. `${{GITHUB_SHA:0:7}}`:
```
${{VAR:position}} - Extracts substring from $VAR at "position"
${{VAR:position:length}} - Extracts "length" characters of substring from $VAR at "position"
```
Github sets a bunch of [default environment variables](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/using-environment-variables#default-environment-variables).
## Github Action Usage
```

```
| Variable | Description |
|----------------------|-----------------------------------------------------------------------------|
| `creds` | ***Required*** Either a path or the contents of a Service Account JSON Key. |
| `config` | Path to config file. Default `deploy.yml` or `deploy.yaml`. |
