certbot-dns-cloudflare no longer installed

Starting with 2.6.0 and also on 2.6.1, I get an error on startup and any time I try to renew my let’s encrypt certs.

Running pip3 list | grep certbot in the docker image shows that only certbot is installed. It looks like the certbot-dns-cloudflare module isn’t installed.

I can run pip3 install certbot-dns-cloudflare in the docker image and the error goes away. I am now able to automatically & manually renew my certs.

Going through the diffs between 2.5.0 and 2.6.0, it looks like the this change to the Dockerfile is causing the problem.

I’m guessing that this is to handle the change to allow for multiple DNS providers.

For those that have the same problem, running docker exec -it PROXY_APP_NAME pip3 install certbot-dns-cloudflare should fix the issue.

Okay, the issue is in processExpiringHosts, where a non-certificate-specific renew is called and no plugins are installed prior. I’ll get to fixing the issue. So as a workaround for now klicking on the three dots next to the certificate and then on “renew now” should work too.

Fixed by #664, can be closed @jc21
