PipAuthenticate@1 - Python pip authenticate v1 task

Use this task to provide authentication for the pip client that installs Python distributions.

Syntax

# Python pip authenticate v1
# Authentication task for the pip client used for installing Python distributions.
- task: PipAuthenticate@1
  inputs:
  # Feeds and Authentication
    #artifactFeeds: # string. My feeds (select below). 
    #pythonDownloadServiceConnections: # string. Feeds from external organizations. 
    #onlyAddExtraIndex: false # boolean. Don't set primary index URL. Default: false.

Inputs

artifactFeeds - My feeds (select below)
string.

Specifies a comma-separated list of Azure Artifacts feeds to authenticate with pip.

pythonDownloadServiceConnections - Feeds from external organizations
string.

Specifies a comma-separated list of pip service connection names from external organizations to authenticate with pip.

onlyAddExtraIndex - Don't set primary index URL
boolean. Default value: false.

If this task is set to true, no feed will be set as the primary index URL. All of the configured feeds/endpoints will be set as extra index URLs.

Task control options

All tasks have control options in addition to their task inputs. For more information, see Control options and common task properties.

Output variables

None.

Remarks

Provides authentication for the pip client that is used to install Python distributions.

• When in my pipeline should I run this task?
• My agent is behind a web proxy. Will PipAuthenticate set up pip to use my proxy?
• My Pipeline needs to access a feed in a different project

When in my pipeline should I run this task?

This task must run before you use pip to download Python distributions to an authenticated package source such as Azure Artifacts. There are no other ordering requirements. Multiple invocations of this task will not stack credentials. Every run of the task will erase any previously stored credentials.

My agent is behind a web proxy. Will PipAuthenticate set up pip to use my proxy?

No. While this task itself will work behind a web proxy your agent has been configured to use, it does not configure pip to use the proxy.

To do so, you can:

• Set the environment variables http_proxy, https_proxy and optionally no_proxy to your proxy settings. See Pip official guidelines for details. These are commonly used variables, which other non-Python tools (e.g. curl) may also use.

  Caution

  The http_proxy and no_proxy variables are case-sensitive on Linux and Mac operating systems and must be lowercase. Attempting to use an Azure Pipelines variable to set the environment variable will not work, as it will be converted to uppercase. Instead, set the environment variables on the self-hosted agent's machine and restart the agent.

• Add the proxy settings to the pip config file file using proxy key.
• Use the --proxy command-line option to specify proxy in the form [user:passwd@]proxy.server:port.

My Pipeline needs to access a feed in a different project

If the pipeline is running in a different project than the project hosting the feed, you must set up the other project to grant read/write access to the build service. See Package permissions in Azure Pipelines for more details.

Examples

Download Python distributions from Azure Artifacts feeds without consulting official Python registry

In this example, we are setting authentication for downloading from private Azure Artifacts feeds. The authenticate task creates environment variables PIP_INDEX_URL and PIP_EXTRA_INDEX_URL that are required to download the distributions. The task sets the variables with authentication credentials the task generates for the provided Artifacts feeds. HelloTestPackage must be present in either myTestFeed1 or myTestFeed2; otherwise, the install will fail.

For project-scoped feeds that are in a different project than where the pipeline is running, you must manually give the project and the feed access to the pipeline's project's build service.

- task: PipAuthenticate@1
  displayName: 'Pip Authenticate'
  inputs:
    # Provide list of feed names which you want to authenticate.
    # Project scoped feeds must include the project name in addition to the feed name.
    artifactFeeds: 'project1/myTestFeed1, myTestFeed2'

# Use command line tool to 'pip install'.
- script: |
    pip install HelloTestPackage

Consult official Python registry and then download Python distributions from Azure Artifacts feeds

In this example, we are setting authentication for downloading from a private Azure Artifacts feed, but pypi is consulted first. The authenticate task creates an environment variable PIP_EXTRA_INDEX_URL, which contains auth credentials required to download the distributions. HelloTestPackage will be downloaded from the authenticated feeds only if it's not present in pypi.

For project-scoped feeds that are in a different project than where the pipeline is running, you must manually give the project and the feed access to the pipeline's project's build service.

- task: PipAuthenticate@1
  displayName: 'Pip Authenticate'
  inputs:
    # Provide list of feed names which you want to authenticate.
    # Project scoped feeds must include the project name in addition to the feed name.
    artifactFeeds: 'project1/myTestFeed1, myTestFeed2'
    # Setting this variable to "true" will force pip to get distributions from official python registry first and fallback to feeds mentioned above if distributions are not found there.
    onlyAddExtraIndex: true

# Use command line tool to 'pip install'.
- script: |
    pip install HelloTestPackage

Download Python distributions from other private Python servers

In this example, we are setting authentication for downloading from an external Python distribution server. Create a pip service connection entry for the external service. The authenticate task uses the service connection to create an environment variable PIP_INDEX_URL, which contains auth credentials required to download the distributions. HelloTestPackage has to be present in the pypitest service connection; otherwise, install will fail. If you want pypi to be consulted first, set onlyAddExtraIndex to true.

- task: PipAuthenticate@1
  displayName: 'Pip Authenticate'
  inputs:
    # In this case, name of the service connection is "pypitest". 
    pythonDownloadServiceConnections: pypitest

# Use command line tool to 'pip install'.
- script: |
    pip install HelloTestPackage
