The http proxy is a generic http proxy which is able to proxy both http and https destination calls. The call to the proxy (to control the proxy call) also supports both http and https (https is using a self signed cert). The main usage for the proxy is as a gateway to all services and pod inside a kubernetest cluster. However, it can be used a basic standard http proxy as well.
The proxy opens the http and https port according to the table below.
| Port | Proxy protocol | Usage |
|---|---|---|
| 8080 | http | Proxy call for http, can proxy both http and https |
| 8433 | https | Proxy call for https, can proxy both http and https |
| 8081 | http | Http port for alive check, returns json with basic statistics |
| 8434 | https | Https port for alive check, returns json with basic statistics |
The dir cert contains a self-signed cert. Use the script generate_cert_and_key.sh to generate a new certificate and key before building the container, the certs need to be re-generated. If another cert is used, all three files (cert.crt, key.crt and pass) in the cert dir should be mounted to the dir '/usr/src/app/cert' in the container.
| Operation | curl example |
|---|---|
| proxy http call via http | curl --proxy localhost:8080 http://pms:1234 |
| proxy https call via http | curl --proxy localhost:8080 https://pms:5678 |
| proxy http call via https | curl --proxy-insecure localhost:8433 http://pms:1234 |
| proxy https call via https | curl --proxy-insecure localhost:8433 https://pms:5678 |
| alive check and get stats | curl localhost:8081 |
| alive check and get stats via proxy | curl --proxy localhost:8080 http://localhost:8081 |
Build image
docker build --build-arg NEXUS_PROXY_REPO=nexus3.onap.org:10001/ -t nodejs-http-proxy:latest .
Start the image on both http and https
docker run --rm -it -p 8080:8080 -p 8081:8081 -p 8433:8433 -p 8434:8434 nodejs-http-proxy:latest
It will listen to http ports 8080/8081 and https ports 8433/8434 (using default certificates) at the same time.
The script proxy-build-start.sh do the above two steps in one go. This starts the container in stand-alone mode for basic test.
Basic test is made with the script basic_test.sh which tests proxy. Use the script proxy-build-start.sh to start the proxy in a container first.
