pingap

What is Pingap

A reverse proxy like nginx, built on pingora, simple and efficient.

Feature

• Filter location by host and path
• HTTP 1/2 end to end proxy
• TOML base configuration, file or etcd storage
• Graceful reload and auto restart after the configuration is changed
• Template for http access log
• Admin Web UI configuration
• Genrate TLS certificates from let's encrypt
• Http proxy plugins: compression, static serve, limit, stats, mock, etc.

Start

Loads all configurations from /opt/proxy and run in the background. Log appends to /opt/proxy/pingap.log.

RUST_LOG=INFO pingap -c=/opt/proxy -d --log=/opt/proxy/pingap.log

Graceful restart

Validate the configurations, send quit signal to pingap, then start a new process to handle all requests.

RUST_LOG=INFO pingap -c=/opt/proxy -t \
  && pkill -SIGQUIT pingap \
  && RUST_LOG=INFO pingap -c=/opt/proxy -d -u --log=/opt/proxy/pingap.log

Config

All toml configurations are as follows pingap.toml.

Proxy step

graph TD;
    start("New Request")-->server("HTTP Server");

    server -- "host:HostA, Path:/api/*" --> locationA("Location A")

    server -- "Path:/rest/*"--> locationB("Location B")

    locationA -- "Exec Plugins" --> locationPluginListA("Plugin List A")

    locationB -- "Exec Plugins" --> locationPluginListB("Plugin List B")

    locationPluginListA -- "proxy pass: 10.0.0.1:8001" --> upstreamA1("Upstream A1") --> response

    locationPluginListA -- "proxy pass: 10.0.0.2:8001" --> upstreamA2("Upstream A2") --> response

    locationPluginListA -- "done" --> response

    locationPluginListB -- "proxy pass: 10.0.0.1:8002" --> upstreamB1("Upstream B1") --> response

    locationPluginListB -- "proxy pass: 10.0.0.2:8002" --> upstreamB2("Upstream B2") --> response

    locationPluginListB -- "done" --> response

    response("HTTP Response") --> stop("Logging");
