Camel proxy dev environment

[eguzki]

What

New development environment to test integration between APIcast and proxies built on top of Camel framework

Verification Steps

• Build docker image from this git branch

make runtime-image IMAGE_NAME=apicast-test

• Change the working directory to the camel dev environment directory

cd dev-environments/camel-proxy

• Create the SSL Certificates

make certs

• Run environment

make gateway IMAGE_NAME=apicast-test

• Testing http_proxy use case: APIcast --> camel proxy --> upstream (plain HTTP/1.1)

curl --resolve http-proxy.example.com:8080:127.0.0.1 -v "http://http-proxy.example.com:8080/?user_key=123"

Expected result:

 Added http-proxy.example.com:8080:127.0.0.1 to DNS cache
* Hostname http-proxy.example.com was found in DNS cache
*   Trying 127.0.0.1:8080...
* Connected to http-proxy.example.com (127.0.0.1) port 8080 (#0)
> GET /?user_key=123 HTTP/1.1
> Host: http-proxy.example.com:8080
> User-Agent: curl/7.81.0
> Accept: */*

* Mark bundle as not supporting multiuse

Traffic between APIcast and the camel proxy can be inspected looking at logs from proxy.socat service

docker compose -p camel-proxy logs -f proxy.socat

Traffic between the camel proxy and upstream can be inspected looking at logs from example.com service

docker compose -p camel-proxy logs -f example.com

Camel proxy can be inspected looking at logs from camel.proxy service

docker compose -p camel-proxy logs -f camel.proxy

• Testing https_proxy use case: APIcast --> camel proxy --> upstream (TLS)

curl --resolve https-proxy.example.com:8080:127.0.0.1 -v "http://https-proxy.example.com:8080/?user_key=123"

Expected result:

* Added https-proxy.example.com:8080:127.0.0.1 to DNS cache
* Hostname https-proxy.example.com was found in DNS cache
*   Trying 127.0.0.1:8080...

• Clean env

make clean

LGTM, just some small issues

• The verification steps provide command to the wrong folder

cd dev-environments/keycloak-env/

• Also missing an entry in CHANGELOG file.

Comments addressed.

LGTM!

Sorry about this. This was not my intention. This happened because we merged #1442 before #1441 and the rebase tricked me. Actually it is my fault for not reviewing the changes after rebase and (too) quick merging.

I will create a new PR to fix this
