Automatically obtain certificates

[xmh0511]

This function is demanded, which likes what caddy does.

Hello @xmh0511

I know such a function is very useful. But in my opinion, it makes rpxy more complicated since it requires to handle bunch of rpxy-unrelated options, e.g., API keys, endpoints, etc. So honestly, I am not sure that such approach does match the concept of rpxy, as simple as possible.

Personally I am using rpxy with certificates that are issued by ACME-enabled issuers (like Let's encrypt). Then, every certificate is managed with lego by periodically checking with cron. This still maintains the system really simple and works flawlessly for years.

I’m guessing it’s worth the effort, because if I (and I’m guessing others) are looking for an alternative to the caddy functionality, which, after all the tests is slow, to find either a HAproxy, which will also require significant additional adjustments, or a nginx proxy manager, I which is not even easy, there may be problems with configurations.

This functionality also added significant popularity to the rust-rpxy.

My case is the need to set up servicing of many clients domains that are sent to a number of internal services, with the transfer of the original domain for further processing:

site1.com, site2.com, ..., siteX.com -> myservice.com (round robin)
img.site1.com, img.site2.com, ..., img.siteX.com -> img.myservice.com
login.site1.com, login.site2.com, ..., login.siteX.com -> img.myservice.com

Hmmm, Okay, I will consider positively.

In my current idea, using instant-acme and passing fetched certs/keys via file system should be fine, i.e, the approach overwriting cert/key files. This should work okay with no big change of current rpxy architecture. Also, it persistently stores fetched data and easily resumes after restarting.

Any opinion?

Traefik use json as store.

@junkurihara I think if you add this feature, you will resolve a lot of friction of using rust-rpxy.

I just made a draft PR #168 for supporting TLS-ALPN-01 ACME in rpxy. I will check the function on my servers and will publish after some tests (maybe in a couple of weeks).
If you guys are interested, please check the change and let me know your opinions.

I merged #168 to develop and publish the pre-release 0.9.0-alpha.1
