Add an Azure DevOps Repo

Updated 1 month ago by Michael Cretzman

This topic outlines how to connect Harness accounts and applications with one or more Azure DevOps repositories. You add these repos as Source Repo Providers in Harness.

In this topic:

Before You Begin

Ensure your Git repo is initialized (git init) before connecting Harness to it.

Limitations

  • One Harness Application cannot be in multiple repos.
  • Before Harness syncs with your Git repo, it will confirm that all Harness' settings are in a valid state. If a connection is not working Harness will not sync with your Git repo.

Current Azure DevOps Support in Harness

Azure DevOps support is limited for the following Harness features:

Step: Add Source Repo Provider

To add a source repo, do the following:

  1. Click Setup.
  2. Click Connectors.
  3. Click Source Repo Providers, and then click Add Source Repo Provider. The Git Connector settings appear.

Step: Display Name

Enter a name for the repo connection.

This is the name you will select when you sync your Harness account and applications in Configuration as Code or other settings where you use the repo.

Step: Provider

Currently, this feature is behind the Feature Flag OPTIMIZED_GIT_FETCH_FILES. Contact Harness Support to enable the feature.

In Provider, select Git.

Step: URL

Enter the URL for your DevOps repo, depending on what you selected in Type.

Select HTTPS or SSH for the connection. You will need to provide the protocol-relevant URL in URL. If you use Two-Factor Authentication for your Git repo, connect over HTTPS or SSH.

For SSH, ensure that the key is not OpenSSH, but rather PEM format. To generate an SSHv2 key, use: ssh-keygen -t rsa -m PEM The rsa and -m PEM ensure the algorithm and that the key is PEM.Next, follow the prompts to create the PEM key. For more information, see the  ssh-keygen man page and Connecting to GitHub with SSH.

In your DevOps repo, click Clone, and then copy the URL.

Make sure you copy the URL from Azure and not form it yourself. Azure replaces spaces and other formatting with the correct values and ensures the link will work.

Step: Credentials

Enter your Azure user name.

Enter a password or token.

For token, in Azure, create a Personal Access Token (PAT).

Next, add the token to Harness as a Harness Secret.

Enter the PAT in the secret and select the secret in Select Encrypted Password/Token.

Step: Branch Name

Enter the branch name to sync with Harness, such as masterdev, or myAppName. Do not enter the full URL to the branch.

Names may not contain characters from the Emoticons unicode block.

Option: Delegate Selector

If you want this Connector to use one or more specific Delegates, use a Delegate Selector. If you do not use a Selector, Harness will select a Delegate that has worked in the past for this type of Connector.

In Delegate Selector, select the Selector for the Delegate(s) you want this Connector to use. You add Selectors to Delegates to make sure that they're used to execute the command. For more information, see Select Delegates with Selectors.

Harness will use Delegates matching the Selectors you add.

If you use one Selector, Harness will use any Delegate that has that Selector.

If you select two Selectors, a Delegate must have both Selectors to be selected. That Delegate might also have other Selectors, but it must have the two you selected.

Option: Customize Commit Attributes (Git Sync Only)

When Harness commits or pushes a change to Git as part of syncing, it uses Harness.io and support@harness.io as the author and commit email address of that commit.

In some cases, you might have strong pre-commit limitations on who may or may not commit. In that case, you need to provide an author name and email that is approved to push on that repo. You can add an Author Name and Author Email address that will be applied whenever Harness syncs with the Git repo.

Step: Generate Webhook URL

Enable this checkbox if you want to sync Harness with your repo bidirectionally. Changes made on either end will be synced.

If you simply want Harness changes synched unidirectionally with the repo, disable this checkbox.

When you use this Source Repo Provider to sync a Harness application to a repo bidirectionally, any account or application that uses this Source Repo provider will be synced bidirectionally.

For more information, see Configuration as Code.

Option: Using the Webhook

If you selected the Generate Webhook URL option when adding your Source Repo Provider, the Generated Webhook URL dialog appears. Copy the URL and use it in your repo to enable your repo to sync changes to Harness.

For steps on setting this up in your repo, see Webhooks from Azure. The Webhook is added in Project Settings > Service hooks.

The Azure Service Hook must use Code pushed as its Trigger on this type of event.

Step: Test and Save

To finish configuring this Source Repo Provider:

  1. In the Git Connector settings, click Test.
    Harness verifies the settings you entered.
  2. When testing is successful, click Submit. This Source Repo Provider is now added to Harness.

Next Steps

  • Once a Source Repo Provider is set up, you can use it—at the Harness account level and Application level—to sync your account and/or applications with your Git repo. See Configuration as Code.
  • To trigger Harness workflows and pipelines using Git Webhooks, see Add a Trigger.
  • To sync and clone a Harness Application template in Git, see Onboard Teams Using GitOps.
