Alpine docker with privoxy enabled to work with HTTPS

Docker Privoxy HTTPS

📃 About

Alpine docker with privoxy enabled and configured to work with HTTPS.

It also includes the script made by 'Andrwe Lord Weber' to translate adblock rules to privoxy.

The default configuration is intended for personal use only (ex. raspberry)

💡 Documentation

This image downloads the 'trustedCAs' file from curl.se and also generates the ca-bundle file. So, you only need copy the 'ca-bundle' file and install it on your browser/system.

docker-privoxy-https's Issues

PermissionError: [Errno 13] Permission denied: '/usr/local/etc/privoxy/CA/trustedCAs.pem'

Hello people from this docker project. I was trying to run the docker via docker-compose and I got this error

Attaching to privoxy
privoxy | Traceback (most recent call last):
privoxy | File "/usr/local/bin/privman", line 227, in

privoxy | ^^^^^^^^^^^^^^^^^^^^
privoxy | PermissionError: [Errno 13] Permission denied: '/usr/local/etc/privoxy/CA/trustedCAs.pem'
privoxy exited with code 0

I guess there is a permission issue somewhere in the Dockerfile. I tried running the docker manually but I get the same issue.

Best regards.
