NOTICE - help wanted - Aug 2024

MSFT is ending support of the connector protocol and this module will need to be migrated to the new Teams Workflow method https://devblogs.microsoft.com/microsoft365dev/retirement-of-office-365-connectors-within-microsoft-teams/

PRs welcome, as well as advice of where to direct users if a new project that has the same features but isn't broken by MSFT emerges.

Concourse CI Teams Resource

Sends messages to Microsoft Teams from within Concourse CI pipelines.

Implements the Microsoft Teams Connector protocols and the Concourse CI resource protocols.

Resolves at runtime Concourse CI environment variables referenced in your Teams connector messages such as:

$BUILD_ID
$BUILD_NAME
$BUILD_JOB_NAME
$BUILD_PIPELINE_NAME
$BUILD_TEAM_NAME
$ATC_EXTERNAL_URL

STATUS

• Actively used and supported (as of Oct '21)
• Works with all Concourse CI releases from 11/2016 thru at least 10/2021

SETUP

1. Open the Microsoft Teams UI.
2. Identify the channel you wish to post notifications to - ie: #devops....
3. Open the "more options" menu of that channel and select "Connectors".
4. Select "Incoming Webhook" and respond to the prompts for details like the icon and connector name.
5. Use the webhook url from above in your pipeline source definition. The example below creates an alert resource. Each point in the pipeline labeled alert is a Microsoft Teams Connector message.

PIPELINE EXAMPLE

Source Configuration

    file: {{mypipeline}}-pull-request/pipeline/test-pr.yml
    on_success:
      put: alert
      params:
        text: |
          pull request tested: success
        title: {{mypipeline}} Pull Request Tested
        actionName: {{mypipeline}} Pipeline
        actionTarget: $ATC_EXTERNAL_URL/teams/$BUILD_TEAM_NAME/pipelines/$BUILD_PIPELINE_NAME/jobs/$BUILD_JOB_NAME/builds/$BUILD_NAME
    on_failure:
      put: alert
      params:

        text: |
          pull request tested: **WITH ERRORS**

• One of the following:
  • text: Required. Text of the message to send - markdown supported (higher precedence over text_file)

MORE EXAMPLES

See *.yml files in the directory.

DEVELOPMENT ENVIRONMENT

Testing with docker-compose.

See working standalone docker-compose example in dir.

PROXY SUPPORT

Proxy support testing is limited to squid4. Dev env was created with default squid4 setup.

sudo service squid start
sudo vim /etc/squid/squid.conf
sudo service squid restart
sudo service squid stop

We tested proxy support with squid4. We don't have access to a wide range of proxies.

The ntlm flag on cURL is not set in our implementation but squid4 was happy to call our session ntlm. We're open to PRs for more support of proxies.
