gateway

gateway is a simple API gateway written in Rust.

Simple use: cargo run -- local_config.yml.

Configuration

The configuration files must contain the following keys:

bind_to: # (Mandatory) the `SocketAddr` to listen
crd_label: # TODO
metrics_prefix: gateway_dev
perm_uris: [] # endpoints where to fetch premissions
perm_update_delay: 30 # delay between each permissions update, in seconds
auth_sources: [] # TODO
max_fetch_error_count: u64 # max number of consecutive errors when fetching permissions

# TODO: arbitrary values
websocket_config:
  max_send_queue: 1000
  max_message_size: 1_000_000
  max_frame_size: 1_000_000
  accept_unmasked_frames: true

Optional features

• remove_authorization_header — Remove the header Authorization from the forwarded request

TODO

• Add chain request/response logic

gateway's Issues

[Apidefinitions] If endpoints is an empty property, gateway crashes

ci: switch to kaniko

Improve logging

Logging should probably use something like the log crate, and one of the available logger implementations.

[CI] Outdated rust image

Use a standard configuration format

Using YAML/JSON instead of the in-house Rust-like syntax used right now could greatly simplify the expression parsing code, relying on serde instead

[Permission] Thread panick if one of the perms endpoints return an empty list

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Fail to fetch permissions', src/main.rs:600:41

I will fix this asap !
