Airflow installation plug-in REST API and pits stepped on

1. Installation and deployment:
1. Add below the airflow.cfg configuration file

[core]
plugins_folder = /home/{
    
    USER_NAME}/airflow/plugins

Note: The front of the airflow directory is the absolute path of the directory where airflow is located

2. Under the airflow directory, create a new plugins directory

mkdir plugins

3. Download the installation package

wget https://github.com/teamclairvoyant/airflow-rest-api-plugin/archive/master.zip

4. Unzip the package

unzip master.zip

You can see a directory airflow-rest-api-plugin-master

Go to this directory

cd airflow-rest-api-plugin-master

5. You can see, as shown below

Move the plugins directory directly to the airflow directory, or copy the rest_api_plugin.py file and templates directory under the directory to the plugins directory created in step 2

mv rest_api_plugin.py /home/{
    
    USER_NAME}/airflow/plugins
mv templates /home/{
    
    USER_NAME}/airflow/plugins

6. Add the following after the configuration file airflow.cfg:

[rest_api_plugin]

 # Logs global variables used in the REST API plugin when the plugin is loaded. Set to False by default to avoid too many logging messages.
 # DEFAULT: False
 log_loading = False

 # Filters out loading messages from the standard out
 # DEFAULT: True
 filter_loading_messages_in_cli_response = True

 # HTTP Header Name to be used for authenticating REST calls for the REST API Plugin
 # DEFAULT: 'rest_api_plugin_http_token'
 rest_api_plugin_http_token_header_name = rest_api_plugin_http_token

 # HTTP Token  to be used for authenticating REST calls for the REST API Plugin
 # DEFAULT: None
 # Comment this out to disable Authentication
 rest_api_plugin_expected_http_token = changeme

Note: rest_api_plugin_expected_http_token can be replaced with a custom value

7. Restart the airflow webser service

2. Pit encountered:
1. The following error is reported when restarting:

Both share the same name "rest_api". Blueprints that are created

The display conflict
may be due to: check the
plugin directory to see if there are 2 copies (perhaps in some nested form), for example:

~/airflow/plugins/rest_api_plugin.py
~/airflow/plugins/plugins/rest_api_plugin.py

Scenario:
Put the decompressed airflow-rest-api-plugin-master directory under the airflow directory, instead of directly moving the plugins directory to the airflow directory, but choosing cp copy will also cause this problem.
Conclusion:
don’t let two All plugins directories are under the airflow directory, just remove or delete the useless ones from airflow
. 2. It displays when the zip archive is unzipped, and the unzip command is not found, just download and install it.

yum install -y zip unzip
