Any of the one can be used for testing. Pyscript folder contains ``main.py`` - the main python script that depploys the helm chart of user's choice and returns important configuration of the charts, such as PodIP, Cluster IP, Interface IPs etc. ************************ Important Configurations ************************ In order to run the python script, we need to install Pipenv to create virtual environment. Steps: 1. Install .. code-block:: console pip install --user pipenv 2. To activate the environment .. code-block:: console pipenv shell The last command will automatically read Pipfile.lock and will create an virtual environment. Once this configuration is done. We can move on to run our python script. ************************************************* Procedure to automatically deploy the helm chart ************************************************* Steps: 1. After activating your virtual environment, run the ``main.py``. .. code-block:: console python main.python 2. Enter the location of the chart you want to deploy. For example, lets deploy proxchart .. code-block:: console Enter the location of helm chart: ../charts/proxchart 3. The last command will execute the entire ``main.py`` and will return all the required information about the chart. ******* Output ******* .. code-block:: console Status of helm charts NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION proxchart default 1 2021-09-27 13:22:21.864816 +0530 IST deployed proxchart-0.1.0 1.0 ---------------------------------------------------------------------------------------------------- POD DETAILS ┏━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━┳━━━━━━━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━┳ ┃ POD NAME ┃ NAMESPACE ┃ HOST-IP ┃ PHASE ┃ POD-IP ┃ POD-IPs ┃ ┡━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━━╇━━━━━━━━━━━━━━╇━━━━━━━━━╇━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━┩ │ prox-6db7c6dc9b-l42v4 │ default │ 192.168.49.2 │ Running │ 172.17.0.4 │ [{'ip': '172.17.0.4'}] │ └───────────────────────┴───────────┴──────────────┴─────────┴────────────┴────────────────────────┴ ┏━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓ ┃ POD NAME ┃ INTERFACE IPs ┃ ┡━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┩ │ prox-6db7c6dc9b-l42v4 │ 127.0.0.1/8, 172.17.0.4/16, 127.0.0.1, 172.17.0.4, 172.17.255.255 │ └───────────────────────┴───────────────────────────────────────────────────────────────────┘ DEPLOYMENT DETAILS ┏━━━━━━━━━━━┳━━━━━━━━━━┳━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━┓ ┃ NAME ┃ Type ┃ CLUSTER-IP ┃ EXTERNAL-IP ┃ PORT(S) ┃ ┡━━━━━━━━━━━╇━━━━━━━━━━╇━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━┩ │ proxchart │ NodePort │ 10.103.156.83 │ {} │ 8081:31036/TCP │ └───────────┴──────────┴───────────────┴─────────────┴────────────────┘ ******************** Future Enhancements ******************** In future, more information can be extracted by adding new functions to the file.
