Integrate Workflow with Bitbucket

[edit on GitHub]

Bitbucket integration with Workflow allows Bitbucket to be used as the canonical git repository for projects while at the same time benefiting from Workflow workflow and pipeline automation. When Bitbucket integration is enabled for a project in Bitbucket, you will be able to:

• Review pull requests and make code comments in the Bitbucket webui
• Browse code (including in-flight changes in the Workflow pipeline) using Bitbucket
• Have the target branch (usually master) of a Bitbucket project repository be managed by Workflow. When a change is approved in Workflow, it will perform the merge in Bitbucket

Bitbucket integration is designed for use with Bitbucket 3.x or 4.x and supports connecting a Workflow enterprise with a single Bitbucket server URL. Workflow does not support Bitbucket project repositories that are hosted at https://bitbucket.org at this time. Workflow communicates with Bitbucket using the Bitbucket REST API and HTTP-based git protocol. Workflow authenticates with Bitbucket with a user account over HTTP basic authentication. It is recommended that the connection be protected using SSL.

Trust SSL Certificate

Run the following steps to set up self-signed certificates for Workflow.

Debian

For the Debian platform, do the following:

1. Log into the Workflow server as root.

2. Run the following command:

   cd /usr/local/share/ca-certificates
   

3. Run the following command:

   openssl s_client -showcerts -connect {BITBUCKET_SERVER}:443 </dev/null 2>/dev/null|openssl x509 -outform PEM >{BITBUCKET_SERVER}.crt
   

4. Run the following command:

   update-ca-certificates
   

RHEL, Centos

For Red Hat Enterprise Linux (6.x and higher) and CentOS (6.x and higher), do the following:

1. Log into the Workflow server as root.

2. Run the following command:

   yum install ca-certificates
   

   Note

   For 6.x servers, run this command only once.

3. Run the following command:

   update-ca-trust force-enable
   

   Note

   For 6.x servers, run this command only once.

4. Run the following command:

   cd /etc/pki/ca-trust/source/anchors/
   

5. Run the following command:

   openssl s_client -showcerts -connect {BITBUCKET_SERVER}:443 </dev/null 2>/dev/null|openssl x509 -outform PEM >{BITBUCKET_SERVER}.crt
   

6. Run the following command:

   update-ca-trust extract
   

Set up Integration

Bitbucket integration with Workflow has the following requirements:

1. Shell access with sudo permission to the Workflow server
2. A Workflow user account with admin role in the Workflow enterprise used for this integration
3. The URL for the Bitbucket instance
4. The username and password of a Bitbucket user to use as the service account. This user must have full access (read/write) to the projects you wish to add to Workflow

Add to Workflow

In the Workflow web UI, open the SCM setup page, and then complete the following fields:

• Bitbucket URL - The URL for your Bitbucket instance.
• Bitbucket Username - The username of the service account that Workflow will use to interact with Bitbucket.
• Bitbucket Password - The password for the service account.

Then submit the form to complete this step.

Remove from Workflow

To remove integration with Bitbucket:

1. Update all projects that are integrated with Bitbucket to be integrated with Workflow.
2. In the Workflow webui, open the SCM Setup page.
3. Click the Remove Link button.

Update Integration

To update integration with Bitbucket:

1. In the Workflow web UI, open the SCM Setup page, and update Bitbucket credentials and make changes to the appropriate information.
2. Click the Update button.

Create a Project

Repeat these steps for each Bitbucket project to be added to Workflow:

1. A project repository in Bitbucket with at least one commit.
2. The service account used by Workflow must have full access to this repository.
3. All team members should have read-only access to this repository. Workflow will manage creation of pull requests and merging of pull requests to Bitbucket.

Add an Empty Project

Use the following steps to add an empty project from the Workflow web UI:

1. Open the page for the organization in the Workflow webui, and then click Add a New Project.
2. Select the Bitbucket option from the Source Code Provider bar, and then and enter the Bitbucket project key, repository, and target branch.
3. Click Save & Close.

Import Project

You can repeat these steps for each Bitbucket project to be added to Workflow:

1. Create a local clone of the project from Bitbucket and cd into it.

2. Create a .delivery/cli.toml using delivery setup:

   delivery setup --ent=$DELIVERY_ENTERPRISE --org=$DELIVERY_ORG --user=$DELIVERY_USER_NAME --server=$DELIVERY_SERVER
   

3. Run delivery init to push the code to the empty project in Workflow (as created above). After importing the code, this command will generate a .delivery/config.json file, create a build cookbook, and submit a change to Workflow to initialize a pipeline for the project. Changes are opened in the Workflow web UI. At this point, a corresponding pull request is shown in Bitbucket.

   To initialize a project using a Bitbucket repository, run a command similar to:

   delivery init --bitbucket PROJECT_KEY -r REPO_NAME
   

   where PROJECT_KEY is the name of the project key in Bitbucket and REPO_NAME is the name of the repository in Bitbucket. For example to initialize the anagrams repository in Bitbucket with the TEST project key:

   delivery init --bitbucket TEST -r anagrams
   

   and returns output similar to:

1. In the Workflow web UI, open the Organizations page.
2. Click the pencil button for the project to be updated.
3. Click the Bitbucket tab.
4. Edit the project key and the project repository name.
5. Click Save and Close.

Workflow w/Bitbucket

This section describes the setup and workflow for a team member who will interact with a Bitbucket project that is integrated with Workflow. It is assumed that the initial project is created, imported, and that a Workflow pipeline already exists.

Delivery CLI

Perform the following steps to install the Delivery CLI and setup your project:

1. Install the Delivery CLI.

2. In the command shell, create or navigate to the directory in which project repositories are located.

3. Use the delivery setup command with the following arguments to create the .delivery/cli.toml file:

   delivery setup --ent=$DELIVERY_ENTERPRISE --org=$DELIVERY_ORG --user=$DELIVERY_USER --server=$DELIVERY_SERVER
   

4. Create a local clone of the project repository:

   delivery clone $PROJECT
   

   If the project is cloned from Bitbucket (or if a pre-existing clone is used), add it using delivery remote. The URL for delivery clone can be found on the project’s page in the Workflow web UI.

5. Create a remote with the following:

   git remote add delivery $DELIVERY_CLONE_URL
   

Create a Change

Use the following steps to create a change in Workflow:

1. Create and check out a topic branch for the change, based on the current state of your project’s pipeline (usually from master). For example: git checkout -b great-feature.
2. Make and commit changes to the project as normal.
3. Submit the change to Workflow with the command delivery review. This command will open a URL at which details and progress of the change may be viewed from the Workflow web UI.
4. Verification of changes will begin automatically and a corresponding pull request will be opened in Bitbucket.

Code Review

You may conduct a code review using either Workflow or Bitbucket. However, merging a pull request is handled by Workflow and occurs when a change in Workflow is approved. You cannot merge the pull request from within Bitbucket.

To perform code review using Workflow:

1. Use the URL created by delivery review to go directly to the change in the Workflow web UI, or browse to the change from the Workflow dashboard.
2. Click the Review tab.
3. Browse the changes and make comments.

Approve a Change

When verification is finished in Workflow and the code has been reviewed and is ready to be merged, approve the change. The pull request will be merged and closed in Bitbucket. The feature branch will also be deleted in Bitbucket.

1. Use the URL created by delivery review to go directly to the change in the Workflow web UI, or browse to the change from the Workflow dashboard.
2. Click the Review tab.
3. Click Approve.

Delete a Change

When verification is finished in Workflow, the code has been reviewed, and it is decided the change should never be approved, delete the change in Workflow; the pull request will be declined and closed in Bitbucket. The feature branch will also be deleted in Bitbucket.

Use the URL created by delivery review to go directly to the change, or browse to the change from the dashboard in the Workflow web UI.

1. Click the Review tab.
2. Click Delete.
