OSX .dmg file with GitHub Actions

Intro#

Tauri has a smooth code-signing & notarization functionality built directly into the bundler and configured via the tauri.conf.json
This guide will give a brief overview of how to sign an application, and how to get the app notarized with Apple. All in a GitHub action.

Prerequisits#

• OSX - This will be needed to create/export the certificate.
• Apple Developer Program subscription
• Developer ID Application certificate
  • see this guide for additional help

• Working Tauri application, being built and published via GitHub Actions, as shown in tauri-action

  GitHub Secrets#

  We will need to add a few GitHub secrets for the proper configuration of the GitHub Action. These can be named however you would like, but we must assign them to the correct Tauri variables, so keep them as relevant as possible.

• You can view this guide for how to add GitHub secrets.

The secrets I used are as follows

Once we have established the GitHub Secrets we will need to make some modifications to our GitHub publish action in .github/workflows/main.yml

Workflow Modifications#

All we will have to do from here is assign the GitHub secrets to the proper environment variables.
ENABLE_CODE_SIGNING: ${{ secrets.APPLE_CERTIFICATE }} APPLE_CERTIFICATE: ${{ secrets.APPLE_CERTIFICATE }} APPLE_CERTIFICATE_PASSWORD: ${{ secrets.APPLE_CERTIFICATE_PASSWORD }} APPLE_SIGNING_IDENTITY: ${{ secrets.APPLE_IDENTITY_ID }} APPLE_ID: ${{ secrets.APPLE_ID }} APPLE_PASSWORD: ${{ secrets.APPLE_PASSWORD }}
If you are using the tauri-action publish template, then your result should look similar the the env: portion below.
