Use these values to create and set up a connected app on Salesforce in the following steps.In a separate browser tab, go to your Salesforce Admin homepage.Go to Settings > Identity > Identity Provider.Click the link under the Service Providers section to create a new connected app.Fill in the required “Connected App Name”, “API Name”, and “Contact E-mail” fields. Note the app name for the next step.In the Web App Settings area, click Enable SAML and paste the three values from the Heroku dashboard.Make sure that the “Name ID Format” pick list in the Salesforce interface is set to the format described in the Heroku SSO settings list.Set “Subject type” to “username”.(Make sure that this username represents each user’s actual e-mail address. Some Salesforce installations permit email-like usernames that don’t correspond to working e-mail addresses.)Click Save at the bottom of the page.Finally, grant users access to this connected app to enable SSO.Go to your Salesforce Admin homepage.Click Administer > Manage Users > Profiles.Click the Profile Name of the

Heroku-buildpack-chrome-for-testing by heroku GitHub Readme.md This buildpack installs Google Chrome browser chrome & chromedriver, the Selenium driver for Chrome, in a Heroku app.BackgroundIn summer 2023, the Chrome development team addressed a long-standing problem with keeping Chrome & Chromedriver versions updated and aligned with each other for automated testing environments. This buildpack follows this strategy to keep chrome & chromedriver versions in-sync.InstallationImportantIf migrating from a previous Chrome-chromedriver installation, then remove any pre-existing Chrome or Chromedriver buildpacks from the app. See the migration guide.heroku buildpacks:add -i 1 heroku-community/chrome-for-testingDeploy the app to install Chrome for Testing. 🚀Selecting the Chrome Release ChannelBy default, this buildpack will download the latest Stable release, which is providedby Google.You can control the channel of the release by setting the GOOGLE_CHROME_CHANNELconfig variable to Stable, Beta, Dev, or Canary, and then deploy/build the app.Migrating from Separate BuildpacksRemove Existing InstallationsWhen an app already uses the separate Chrome & Chromedriver buildpacks, remove them from the app, before adding this one:heroku buildpacks:remove heroku/google-chromeheroku buildpacks:remove heroku/chromedriverheroku buildpacks:add -i 1 heroku-community/chrome-for-testingPath to Installed ExecutablesAfter being installed by this buildpack, chrome & chromedriver are set in the PATH of dynos.If the absolute paths are required, you can discover their location in an app:>>> heroku run bash$ which chrome/app/.chrome-for-testing/chrome-linux64/chrome$ which chromedriver/app/.chrome-for-testing/chromedriver-linux64/chromedriverThese locations may change in future versions of this buildpack, so please allow the operating system to resolve their locations from PATH, if possible.Changes to Command FlagsThe prior heroku/google-chrome buildpack wrapped the chrome command with default flags using a shim script. This is no longer implemented for chrome in this buildpack, to support evolving changes to the Chrome for Testing flags, such as the --headless=new variation.Depending on how an app is already setup for testing with Chrome, it may not require any changes.If the app fails to start Chrome, please ensure that the following argument flags are set wherever chrome is invoked:--headless--no-sandboxSome use-cases may require these flags too:--disable-gpu--remote-debugging-port=9222Releasing a new versionFor buildpack maintainers only.Create a new release on GitHub.Publish the release tag in Heroku Buildpack Registry.

Heroku ArchitectureStacks (operating system images)Heroku-24 Stack Last updated February 21, 2025 Table of ContentsWhat’s newAvailable softwareSupport periodUsing Heroku-24Upgrading to Heroku-24Heroku-24 Docker images This article describes the Heroku-24 stack, based on Ubuntu 24.04. What is a stack?What’s newThis stack is now based on Ubuntu 24.04, compared to Ubuntu 22.04 used in theHeroku-22 stack.The most important changes compared to Heroku-22 are:We adjusted the Ubuntu packages installed on the stack to reduce thesize of the base images:We removed some less frequently used packages (such as Bazaar and Mercurial).We made some tools that are typically only required during the build (such as GCC, Make, Gitand system Python) available only at build time, rather than at app run time too.We made several changes to the Heroku-24 Docker images:We now publish them as multi-architecture images, that support both the amd64 andarm64 architectures instead of only amd64.We now set the default image Linux user to heroku instead of root.See the upgrade notes for more detailed change information.Available softwareEvery stack on Heroku supports different operating system packages and language runtime versions.This support is typically confined to software that was still actively developed by the respectivemaintainers at the time the stack was first released.Language runtimesFor the most accurate information on supported language runtime versions, please check theindividual language pages: Buildpack Shorthand Runtime versions Ruby heroku/ruby Runtime versions Node.js heroku/nodejs Runtime versions Python heroku/python Runtime versions Java heroku/java Runtime versions PHP heroku/php Runtime versions Go heroku/go Runtime versions Operating system packagesFor a full list of operating system packages available on

Heroku-24, please refer to articleUbuntu Packages on Heroku Stacks.Support periodHeroku-24 is based on Ubuntu 24.04. It will be supported through April 2029. Learn more aboutHeroku’s stack update policy.Using Heroku-24You can specify a stack when creating an app:$ heroku create --stack heroku-24You may change the stack on an existing app; the next build performed will then use the new stack:$ heroku stack:set heroku-24If you are using app.json, you should also specify the stack there toensure that your Review Apps and Heroku CI runs use the same stack:{ "stack": "heroku-24"}An existing app’s stack cannot be changed using app.json. The stack specified is only appliedto newly created apps that are a Review App, aHeroku CI test run app, or an app created using a Heroku Button.Upgrading to Heroku-24Please refer to the stack upgrading guide to understand theprocedures to follow when upgrading to a new stack.We recommend that you monitor your application closely after migrating an app to the new stackto ensure it’s performing correctly.Upgrade notesChanges to GitGit is now only available at build time and not also at app run time.The .git/ metadata directory for an app’s Git repository has never been available during thebuild or at run time, even when using older stacks. As such, if your app invokes Git at run timeto determine the deployed source revision (commit SHA), these calls will have always failed dueto the lack of a valid repository.If you need to determine the currently deployed revision of your app, either use the env varSOURCE_COMMIT during the build,. brew tap heroku/brew brew install heroku or download the installer.
