I have a project that utilizes microservices. I am trying to use wire-mock to create a test environment.
How can I proxy multiple URLs using docker-compose.
Here is my docker-compose file.
networks:
ft-simulator:
external: false
services:
app:
depends_on:
- nginx
environment:
- SPRING_PROFILES_ACTIVE=simulator
- JAVA_FLAGS=-Dhttp.proxyHost=wiremock -Dhttp.proxyPort=8080
healthcheck:
interval: 1m
retries: 3
test:
- CMD
- curl
- -f
- http://localhost:8080/health
timeout: 10s
image: ft-simulator:latest
ports:
- "8080:8080"
networks:
ft-simulator:
aliases:
- bcp
nginx:
image: nginx
ports:
- "80:80"
- "443:443"
networks:
- ft-simulator
wiremock:
image: rodolpheche/wiremock:2.8.0-alpine
networks:
- ft-simulator
ports:
- "8081:8080"
volumes:
- "$PWD/stubs:/home/wiremock"
command: ["--proxy-all=http://bcp:8080, http://www.google.com"]
version: '3.1'
The Google is simply a placeholder until it starts up.
When I run docker-compose up I get the following error
crp11070m:wiremock-simulation john.hamlett$ docker logs -f wiremocksimulation_wiremock_1

It isn't possible to proxy to more than one target URL at the same time using the --proxy-all
parameter.
What you can do is vary the proxy target based on the incoming request by creating a stub mapping with a proxy response for each route e.g.
Route 1:
{
"request": {
"urlPattern": "/route1/.*"
},
"response": {
"proxyBaseUrl" : "http://target-host-1.com"
}
}
Route 2:
{
"request": {
"urlPattern": "/route2/.*"
},
"response": {
"proxyBaseUrl" : "http://target-host-2.com"
}
}
Note that the URL path part will get added to the URL, so you'd end up with requests proxied to http://target-host-1.com/route1/whatever
and http://target-host-2.com/route2/whatever
.
