cosmos-cert-extractor

This is a python script periodically running (every 5 minutes) to extract the TLS certificate from the Cosmos config file. The use case I set this up for is in order to use the certificate in my Adguard Home instance.

How to use

Make sure your volume mounts are set up correctly:

• The cosmos volume or path must be mapped to /input.
• The adguard-config volume must be mapped to /output.

The cert.pem and key.pem file will be created and updated in /output/certs and can then be used in Adguard using these paths:

• /opt/adguardhome/conf/certs/cert.pem
• /opt/adguardhome/conf/certs/key.pem
