ESCG (Enhanced Spring Cloud Gateway)

A enterprise-level enhanced gateway based on spring cloud gateway, out of the box, supports such as canary request-based response cache filter, canary load balancer, universal signature authentication filter, oidc v1/oauth2.x authentication filter, ip filter, Traffic replication filter, quota-request limiter-based filter Injector, canary-based fault injector filter, and canary-based humanized log filter, etc.

Tips: The latest version and documentation are currently being sorted out. It is recommended to deploy in the test environment first. If you have any questions or suggestions, please submit an Issue

1. Developer guide

Building

git clone https://github.com/wl4g/escg.git
cd escg/

# The profiles supports: -Pbuild:tar, -Pbuild:springjar, -Pbuild:docker, -Pbuild:native
mvn -U install -DskipTests -Pbuild:tar

2. Examples

2.1 Generating self-certificate

cd src/main/resources/cert.d/
./cert-tool.sh ca
./cert-tool.sh pem-p12 ca.pem ca-key.pem

./cert-tool.sh cert wl4g.io 192.168.88.2,10.88.8.5
./cert-tool.sh pem-p12 wl4g.io.pem wl4g.io-key.pem

./cert-tool.sh cert client1 192.168.88.2,10.88.8.5
./cert-tool.sh pem-p12 client1.pem client1-key.pem

Note: To create a certificate, you must specify a list of hosts, otherwise, for example, an error will be reported when executing curl: no alternative certificate subject name matches target host name '192.168.88.3', Using the above script tool will contain localhost,127.0.0.1 by default.

2.2 Ingress TLS

2.9 Traffic Replication

The following example requires startup corresponding configuration file: src/test/resources/bootstrap.yml

spring:
  profiles:
    include: "service-discovery,route-filter-splitting"

## Mock actual upstream http server.
python3 -m http.server -b 0.0.0.0 8888

## Mock traffic mirror upstream http server. see: escg-route.yaml#secure-httpbin-service-route
## Online by default: http://httpbin.org/
## [Optional] You can also use docker to local build an httpbin server.
#docker run -d --name=httpbin -p 8889:80 kennethreitz/httpbin

## 1. Send a mock request and observe that both terminals have output.
## 2. Then observe the output of the simulated mirror http server, and the response of the simulated real http server.

5. FAQ

5.1 When the request limiter is configured, and then the log level is set to `com.wl4g.escg.requestlimit=TRACE`, an error will be displayed: `ERR Error running ... @user_script:1: user_script:1: attempt to call field 'replicate_commands' (a nil value)`

Refer1: stackoverflow attempt-to-call-field-replicate-commands-a-nil-value
Resolved: Since redis3.0 does not support the command 'replicate_commands()', just upgrade to redis3.2+
