Coded it one weekend to simplify my own life,

Definitely feel free to drop in issues or PR if interested in pushing this project further.


Quickstart

Setup virtual env & depedencies

> virtualenv -p python3 venv
> source venv/bin/activate
> pip3 install -r requirements.txt

Credentials file

Create an .env file in the project folder with the following structure and input values.

[GODADDY]
API_KEY=xxxxxxx
API_SECRET=xxxxxxx

[AZURE]
CERT_VAULT_URL=https://xxxxxxx.vault.azure.net/
CLIENT_ID=xxxxxxx
TENANT_ID=xxxxxxx
SECRET=xxxxxxx

[CERTS]
SECTIONS=ADMIN_SERVER_CERT,SHOP_SERVER_CERT

[ADMIN_SERVER_CERT]
NAME=xxxxxxx
LOCAL_PFX_PATH=/xxxxxxx/admin-server.veniqa.com/certificate.pfx
PASSWORD=xxxxxxx

[SHOP_SERVER_CERT]
NAME=xxxxxxx
LOCAL_PFX_PATH=/xxxxxxx/shop-server.veniqa.com/certificate.pfx
PASSWORD=xxxxxxx

Note

  • Anything from the CERTS section and below can be entered later before running the cert processor.
  • [ADMIN_SERVER_CERT] is an example of a section that is needed per certificate you want renewed. You can name such a section anything as long as you fulfill the following conditions:
    • It has all the key-value pairs as shown in the example
    • The custom section's name is included in the [CERTS] section's SECTIONS entry

Make shell scripts executables

> chmod +x kickoff.sh
> chmod +x dns_challenge_hook.sh
> chmod +x cert_processor.sh

Kickoff the certificate renewal process

Command: ./kickoff.sh

Run Cert Processor

Once the renewed certificates have been generated,

  • Update the paths and passwords in the cert_processor.sh to point to the folder of your choice
  • Run ./cert_processor.sh

Point your app to use the cert in Azure vault

The automated process ends with renewing the certificate and updating in the Azure Vault

You will then have to log in and point your app to use the updated certificate stored in your Azure vault. I couldn't find an API to facilitate this part. If you find a way, feel free to drop an issue with the resource.
