For each operator, you can define its own extra links that can redirect users to external systems. The extra link buttons will be available on the task page:

The following code shows how to add extra links to an operator:

from airflow.models.baseoperator import BaseOperator, BaseOperatorLink
from airflow.utils.decorators import apply_defaults


class GoogleLink(BaseOperatorLink):

    def get_link(self, operator, dttm):
        return "https://www.google.com"

class MyFirstOperator(BaseOperator):

    operator_extra_link_dict = {
        "Google": GoogleLink(),
    }

    @apply_defaults
    def __init__(self, *args, **kwargs):
        super(MyFirstOperator, self).__init__(*args, **kwargs)

    def execute(self, context):
        self.log.info("Hello World!")

You can also add a global operator extra link that will be available to all the operators through airflow plugin. Learn more about it in the plugin example.
