You can also use the [coder/setup-action](https://github.com/coder/setup-coder)
GitHub Action to install the Coder CLI and push new template versions.

## 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

Before proceeding, ensure the following:

- **Coder CLI** is installed and configured in your environment.
- **Terraform CLI** is installed and available in your CI environment.
- Access to your **Coder instance** with the appropriate
[permissions](../admin/users/groups-roles.md#roles).

## Example GitHub Action Workflow

Below is an example workflow for testing and publishing a template using GitHub
Actions. The workflow first validates the Terraform template, pushes the
template to Coder without activating it, tests the template by creating a
workspace, and then promotes the template version to active upon successful
workspace creation.

### Step-by-Step Process

1. **Validate the Terraform template.**
2. **Push the template to Coder without activating it.**
3. **Test the template by creating a workspace.**
4. **Promote 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
run: |
coder create -t $TEMPLATE_NAME --template-version ${{ steps.name.outputs.version_name }} test-${{ steps.name.outputs.version_name }} --yes

- name: Run some example commands
run: |
coder config-ssh --yes
# run some example commands
coder ssh test-${{ steps.name.outputs.version_name }} -- make build

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