## Overview

This guide demonstrates how to test and publish Coder templates in a Continuous
Integration (CI) pipeline using the
[coder/setup-action](https://github.com/coder/setup-coder). This workflow
ensures your templates are validated, tested, and promoted seamlessly.

## Prerequisites

- Install and configure Coder CLI in your environment.
- Install Terraform CLI in your CI environment.
- Create a [headless user](../admin/users/headless-auth.md) with the
[user roles and permissions](../admin/users/groups-roles.md#roles) to manage
templates and run workspaces.

## Creating the headless user

```shell
coder users create \
--username machine-user \
--email machine-user@example.com \
--login-type none

coder tokens create --user machine-user --lifetime 8760h
# Copy the token and store it in a secret in your CI environment with the name `CODER_SESSION_TOKEN`
```

## Example GitHub Action Workflow

This example workflow tests and publishes a template using GitHub Actions.

The workflow:

1. Validates the Terraform template.
1. Pushes the template to Coder without activating it.
1. Tests the template by creating a workspace.
1. Promotes the template version to active upon successful workspace creation.

### Workflow File

Save the following workflow file as `.github/workflows/publish-template.yaml` in
your repository:

```yaml
name: Test and Publish Coder Template

on:
push:
branches:
- main
workflow_dispatch:

jobs:
test-and-publish:
runs-on: ubuntu-latest
env:
TEMPLATE_NAME: "my-template"
steps:
- name: Checkout repository
uses: actions/checkout@v4

- name: Set up Terraform
uses: hashicorp/setup-terraform@v2
with:
terraform_version: latest

- name: Set up Coder CLI
uses: coder/setup-action@v1
with:
access_url: "https://coder.example.com"
coder_session_token: ${{ secrets.CODER_SESSION_TOKEN }}

- name: Validate Terraform template
run: terraform validate

- name: Get short commit SHA to use as template version name
id: name
run: echo "version_name=$(git rev-parse --short HEAD)" >> $GITHUB_OUTPUT

- name: Get latest commit title to use as template version description
id: message
run:
echo "pr_title=$(git log --format=%s -n 1 ${{ github.sha }})" >>
$GITHUB_OUTPUT

- name: Push template to Coder
run: |
coder templates push $TEMPLATE_NAME --activate=false --name ${{ steps.name.outputs.version_name }} --message "${{ steps.message.outputs.pr_title }}" --yes

- name: Create a test workspace and run some example commands
run: |
coder create -t $TEMPLATE_NAME --template-version ${{ steps.name.outputs.version_name }} test-${{ steps.name.outputs.version_name }} --yes
coder config-ssh --yes
# run some example commands
coder ssh test-${{ steps.name.outputs.version_name }} -- make build

- name: Delete the test workspace
if: always()
run: coder delete test-${{ steps.name.outputs.version_name }} --yes

- name: Promote template version
if: success()
run: |
coder template version promote --template=$TEMPLATE_NAME --template-version=${{ steps.name.outputs.version_name }} --yes
