Certbot renew request saves certificates to -0001 to folder

I’ve been using Let’s Encrypt for almost a year and it’s fantastic - so well done to all involved.

I recently dockerized everything, and everything appears to be working very well except for a small issue I’m having around using certbot to renew my certificates.

The certbot renewal request went through, but it keeps saving the renewed certificates to a new folder with -0001 appended to my domain : /etc/letsencrypt/live/humankode.com-0001

The command I’m running is in a cron job.

I’m running Ubuntu 16.04 on an Amazon EC2 instance. Everything is dockerized.

The command I used to issue the renewal was:

sudo docker run --rm -it --name certbot \
-v "/docker-volumes/etc/letsencrypt:/etc/letsencrypt" \
-v "/docker-volumes/var/lib/letsencrypt:/var/lib/letsencrypt" \
-v "/docker-volumes/data/letsencrypt:/data/letsencrypt" \
certbot/certbot \
certonly --webroot --webroot-path=/data/letsencrypt \
-d humankode.com -d www.humankode.com \
--renew-by-default \
--force-renewal \
--email email@gmail.com \
--agree-tos \
--manual-public-ip-logging-ok

The response I got was:

Hi @thecarlo,

The intended way to renew your certificates is just certbot renew (ideally twice a day from a cron job or systemd timer). If you specify the whole issuance command again, you do have a risk of getting the -0001 if you specify a list of domain names that’s in any way different from the list of domain names covered by the existing certificate (whether by adding or removing names). Could you try running certbot certificates to see whether the coverage of your new and old certificates differs in some way?

still waiting for the
certbot certificates

in the interim, take a look at: https://crt.sh/?q=humankode.com
which seems to indicate that your “renewal” process is actually issuing new certs…

also why use “certonly” ?

Hi @schoen,

I ran the certbot renew command:

sudo docker run --rm -it --name certbot \
-v "/docker-volumes/etc/letsencrypt:/etc/letsencrypt" \
-v "/docker-volumes/var/lib/letsencrypt:/var/lib/letsencrypt" \
-v "/docker-volumes/data/letsencrypt:/data/letsencrypt" \
certbot/certbot \
renew 

And got the following error:

Saving debug log to /var/log/letsencrypt/letsencrypt.log

-------------------------------------------------------------------------------
Processing /etc/letsencrypt/renewal/humankode.com-0001.conf
-------------------------------------------------------------------------------

Renewal configuration file /etc/letsencrypt/renewal/humankode.com-0001.conf is broken. Skipping.

-------------------------------------------------------------------------------

No renewals were attempted.

Additionally, the following renewal configuration files were invalid:
  /etc/letsencrypt/renewal/humankode.com-0001.conf (parsefail)
-------------------------------------------------------------------------------
0 renew failure(s), 1 parse failure(s)

Any ideas on how to proceed from here? What would be the best way to reset the button in terms of getting rid of the existing artifacts so that I can issue a new cert and test certbot renew again?

Start with this:
certbot certificates

Also you’re issuing a lot of certificates. Keep the rate limits in mind and use the staging environment to experiment (certbot --staging and certbot renew --dry-run).

I deleted all the -0001 subfolders and artifacts.
ls -la /docker-volumes/etc/letsencrypt/live/humankode.com

returns

If I run the command

I get

Ok, I managed to solve the issue. Thanks for all the input.

I found the root of the problem.
When I initially created the certificate, I used a non-official docker certbot image to issue the initial certificates.

I used deliverous/certbot instead of the certbot/certbot image. Then, when I tried to renew the certificate, it placed the renewed certificates in a -0001 suffix folder.

I confirmed this by issuing new certificates using the --staging flag on the deliverous/certbot image, and then proceeded by attempting to renew the certificates using the certbot/certbot image, and then got the -0001 suffix folder.

I then deleted everything and issued new certificates using the certbot/certbot image, and renewed using the certbot/certbot image, and everything worked fine.

There were obviously differences in how the certificates were created with the deliverous/certbot image.

From now on, I’ll stick to the official certbot images.
