Slow creation for new domain

[cpontvieux-systra]

https://github.com/nginx-proxy/acme-companion/blob/9fbd6684efba2d740f195f12888362307d26bb59/app/letsencrypt_service#L432C5-L432C5

This loop can take a long moment if you have lots of domains/containers. This is a NOT a problem for certificate renewal, but it is for certificate CREATION.

This list is ordered (by go) in alphabetical order. If you new domain starts with the letter V for instance, you have to wait for ACME script to walk through all previous domains (even if no action required yet) before reaching you newly domain.

This can prevent your domain to be ready for several minutes if you have lots of domains and this time vary a lot based on your domain name (alphabetical order).

• What solution is possible?
• Can this loop be split into multiple chunks and run in parallel? And then using a wait before going on?
• Did I reach a point where nginx + acme-companion is not a viable solution anymore? What do you recommend if this is the case?

@buchdag Thanks for providing a fix for this issue (and maintaining this project).

I however have some interrogations regarding the fix. My understanding of how the acme companion works is that the nginx service is restarted at the end of the acme loop. So basically, changing the order of processing certificates should not change anything ? right ?

I was wondering also, when the processing is started in response of an event, can't we only do the loop over the certificates related to the container events ?

Thanks,

@mickaelperrin you made a point, but it’s better to open a new issue than commenting on a close one ;-)
