issue-keyword tooltipped tooltipped-se" aria-label="This commit closes issue #3627.">fixes #3627. this reorganizes the logic in pd's startup code related to automatically managed https functionality. ## 🎨 background & motivation this PR, besides cleaning up the `rustls-acme`-related auto-https logic, is also interested in *creating a state-of-affairs that will dovetail into pr #3522*. in particular, this expression to start the GRPC serve given a bound listener... ```rust tokio::task::Builder::new() .name("grpc_server") .spawn(grpc_server.serve_with_incoming(tls_incoming)) .expect("failed to spawn grpc server") ``` ...should be adjusted so as to work with an `axum::Router`. ### ⚖️ `rustls-acme` and `tokio-rustls-acme` quoth the #3627 description, citing an earlier comment: > In the ~year since this code was written, there may be better options. > `tokio-rustls-acme` seems promising \- <#3522 (comment)> for reference, the repositories for each live here, and here: - <https://github.com/FlorianUekermann/rustls-acme> - <https://github.com/n0-computer/tokio-rustls-acme> after some comparison, i have come to the opinion that `rustls-acme` will still be adequate for our purposes. the latter is a fork of the former, but active development appears to have continued in the former, and i did not see any particular "_must-have_" features for us in the latter. ## 🎴 changes this commit moves some of the auto-https related code from the `main` entrypoint, into standalone functions in `pd::main`. some constants are defined, to keep control flow clear and to help facilitate the addition of future options e.g. a flag to control the LetsEncrypt environment to use. ## 🚰 dropping down to `axum`; a brief note on future upgrades as stated above, we want to switch to an `axum::Router`. this means that we won't be able to use the `AcmeConfig::incoming` function. the `rustls-acme` library provides some "low-level" examples this work is based upon - <https://github.com/FlorianUekermann/rustls-acme/blob/main/examples/low_level_tokio.rs> - <https://github.com/FlorianUekermann/rustls-acme/blob/main/examples/low_level_axum.rs> we also use `tonic` 0.10.2 in pd, and elsewhere in the penumbra monorepo. tonic isn't using hyper 1.x yet. this was being worked on in hyperium/tonic#1583, continued on in hyperium/tonic#1595, and tracked in hyperium/tonic#1579. that work also depends upon hyperium/hyper#3461. we will need to be wait for tonic to finish its migration over to hyper 1.0, see: hyperium/tonic#1579 (comment) this is understandable, but i make note of this situation as a signpost for our future selves when considering a migration to recent versions of axum-server, axum, rustls-acme, or hyper. for now, it's easiest to stay in lock-step with tonic, and we can revisit the upgrade path(s) at a future date. === Refs: #3627 Refs: #3646 Refs: #3522
