Outputs

Outputs essential variables from Pritunl Client setup, supporting and extending automation, integration, and audit processes.

client-id — a unique string identifier generated during the profile setup process.

client-ids — a JSON array containing all client IDs and names in the profile, with each entry represented as a key-value pair.

Retrieving Step Outputs

[!NOTE] The pritunl-connection refers to the Setup Step ID. Make sure to replace it with the actual step ID in your workflow.

[!TIP]

Examples

Provided that profile-file is available, we have the flexibility to generate multiple scenarios.

Minimum Working Configuration

Establish a VPN connection with just a few lines of code! Simply set the required profile-file input, and let the action handle the rest.

- name: Setup Pritunl Profile and Start VPN Connection
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}

[!TIP] See a working example of this action in our connection-tests-basic.yml. This example demonstrates a basic setup and connection test.

Authenticate with PIN or Password

If your VPN connection requires authentication, use the profile-pin input to provide a PIN or password.

- name: Setup Pritunl Profile and Start VPN Connection
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}
    profile-pin: ${{ secrets.PRITUNL_PROFILE_PIN }}

Specifying Server or Servers in a Multi-Server Profile

Select one or more servers by specifying their names. You can use:

- name: Setup Pritunl Profile and Start VPN Connection
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}

    # Specify a single server using its short name
    profile-server: dev-team

    # Connect to multiple servers using short names
    # profile-server: dev-team, qa-team

    # Use a full profile name to specify a single server
    # profile-server: gha-automator-qa1 (dev-team)

    # Use full profile names to specify multiple servers
    # profile-server: gha-automator-qa1 (dev-team), gha-automator-qa1 (qa-team)

[!TIP] See an example of connecting to multiple servers in our connection-tests-multi-server-profile.yml file. This workflow demonstrates how to configure and test connections to multiple servers using a single profile.

Specify Client Version

Use a specific version of the Pritunl client.

- name: Setup Pritunl Profile and Start VPN Connection
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}
    client-version: 1.3.3883.60

Specify VPN Mode

Use a specific VPN mode (e.g., WireGuard).

- name: Setup Pritunl Profile and Start VPN Connection
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}
    vpn-mode: wg

Manual Connection Control

Demonstrates manual control over the VPN connection, including starting, stopping, and checking the connection status.

# Set up Pritunl profile and store client ID for later use
- name: Setup Pritunl Profile
  id: pritunl-connection # A `Setup Step ID` has been added as a reference identifier for the output `client-id`.
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}
    start-connection: false # Do not establish a connection in this step.

# Start VPN connection using stored client ID and password (use stored secret if available, otherwise use an empty string)
- name: Start VPN Connection Manually
  shell: bash
  run: |
    pritunl-client start ${{ steps.pritunl-connection.outputs.client-id }} \
      --password ${{ secrets.PRITUNL_PROFILE_PIN || '' }}

    sleep 10 # Wait for 10 seconds to allow the connection to establish

# Display VPN connection status
- name: Display VPN Connection Status Manually
  shell: bash
  run: |
    pritunl-client list --json | jq 'sort_by(.name) | .[0] | { "Profile Name": .name, "Client Address": .client_address }'

# Insert your CI/CD core logic here
- name: Your CI/CD Core Logic Here

# Stop VPN connection using stored client ID (always run, even on failure)
- name: Stop VPN Connection Manually
  if: ${{ always() }}
  shell: bash
  run: |
    pritunl-client stop ${{ steps.pritunl-connection.outputs.client-id }}

[!TIP] See a working example of manual connection control in our connection-tests-manual-control.yml for the readme example manual test.

Controlling Step Outputs Visibility in GitHub Actions Log

By default, step outputs are hidden in the GitHub Actions log to keep it clean and clutter-free. To reveal step outputs, set concealed-outputs to false.

- name: Setup Pritunl Profile and Start VPN Connection
  uses: nathanielvarona/pritunl-client-github-action@v1
  with:
    profile-file: ${{ secrets.PRITUNL_PROFILE_FILE }}
    concealed-outputs: false # Set to false to reveal step outputs in the GitHub Actions log

Working with Pritunl Profile File

The Pritunl Client CLI requires a specific file format, and GitHub has limitations on uploading binary files. To store the Pritunl Profile in GitHub Secrets, we need to convert the tar archive file to a base64 text file format.

Four Easy Steps

1. Obtain the Profile File

Download the Profile File from the User Profile Page or obtain it from your Infrastructure Team. If you receive a tar file, proceed to Step 2.

curl -sSL https://vpn.domain.tld/key/a1b2c3d4e5.tar -o ./pritunl.profile.tar

2. Convert to Base64

Convert the Pritunl Profile File from tar archive file format to base64 text file format.

base64 --wrap 0 ./pritunl.profile.tar > ./pritunl.profile.base64

3. Copy the Base64-encoded Data

CLI (Command-Line Interface)
GUI (Graphical User Interface)
  1. Open the file ./pritunl.profile.base64 in a code editor (e.g., code or vim) and select all the text (or use the keyboard shortcut Ctrl+A or Cmd+A).
  2. Right-click and select "Copy" (or use the keyboard shortcut Ctrl+C or Cmd+C).

4. Create a GitHub Action Secret

Create a GitHub Action Secret (e.g., PRITUNL_PROFILE_FILE) and paste the entire base64 text data as the secret value.

Pro Tip!

Reveal the Magic: One-liner Shorthand Script Simplify the first three steps with this handy one-liner invocation script: ```bash # Define a private function to read file data or download from URL # This function is used internally to fetch the profile data __get_profile_data() { # Check if the input is a file if [ -f "$1" ]; then # If it's a file, read its contents cat "$1" else # If it's not a file, assume it's a URL and download the data curl -sSL "$1" fi } # Define a public function to encode a profile and copy it to the clipboard # This function takes a file path or URL as input, encodes the data to base64, # and copies it to the clipboard encode_profile_and_copy() { # Check if a file path or URL is provided as an argument if [ $# -eq 0 ]; then # If no argument is provided, print an error message and usage instructions echo "Error: No argument provided" echo "Usage: $(basename "$0") " echo "Examples:" echo " Using a URL: $(basename "$0") https://vpn.domain.tld/key/a1b2c3d4e5.tar" echo " Using a local file path: $(basename "$0") ./pritunl.profile.tar" return 1 fi # Get the profile data using the private function __get_profile_data "$1" | # Encode the data to base64 base64 --wrap 0 | # Copy the encoded data to the clipboard { # Use pbcopy for macOS pbcopy } || { # Use xclip or xsel for Linux or WSL xclip -selection clipboard || xsel --clipboard --input } } ``` _Check out this script ([pritunl-profile-encode.sh](https://github.com/nathanielvarona/dotfiles/blob/master/.scripts/source/pritunl-profile-encode.sh)) from [nathanielvarona/dotfiles](https://github.com/nathanielvarona/dotfiles) for an example of how to implement one-liner shorthand script._

Supported Arm64 Architecture Runners

Supports GitHub Actions runners with Arm64 architecture, enabling users to run workflows on Arm64-based systems.

[!TIP] See an example of Arm64 support in our connection-tests-basic.yml file.

[!WARNING] arm64 — While most runners are free to use in public repositories, certain Arm64 runners may incur usage charges to your account.

For details on runner billing, please refer to the "About billing for GitHub Actions" documentation.
