💎 ANN: oauth2 v2.0.15 & v2.0.16 w/ full E2E example

#docker #testing #security #ruby

Complete E2E single file script against navikt/mock-oauth2-server

NOTE: The mock test server was added to source in oauth v2.0.11, and has now been upgraded to the latest version of mock-oauth2-server. The mock test server is not in the packaged gem.

docker compose -f docker-compose-ssl.yml up -d --wait
ruby examples/e2e.rb
# If your machine is slow or Docker pulls are cold, increase the wait:
E2E_WAIT_TIMEOUT=120 ruby examples/e2e.rb
# The mock server serves HTTP on 8080; the example points to http://localhost:8080 by default.

The output should be something like this:

➜  ruby examples/e2e.rb
Access token (truncated): eyJraWQiOiJkZWZhdWx0...
userinfo status: 200
userinfo body: {"sub" => "demo-sub", "aud" => ["demo-aud"], "nbf" => 1757816758000, "iss" => "http://localhost:8080/default", "exp" => 1757820358000, "iat" => 1757816758000, "jti" => "d63b97a7-ebe5-4dea-93e6-d542caba6104"}
E2E complete

Make sure to shut down the mock server when you are done:

docker compose -f docker-compose-ssl.yml down

Troubleshooting: validate connectivity to the mock server

Check container status and port mapping:
- docker compose -f docker-compose-ssl.yml ps
From the host, try the discovery URL directly (this is what the example uses by default):
- curl -v http://localhost:8080/default/.well-known/openid-configuration
- If that fails immediately, also try: curl -v --connect-timeout 2 http://127.0.0.1:8080/default/.well-known/openid-configuration
From inside the container (to distinguish container vs host networking):
- docker exec -it oauth2-mock-oauth2-server-1 curl -v http://127.0.0.1:8080/default/.well-known/openid-configuration
Simple TCP probe from the host:
- nc -vz localhost 8080 # or: ruby -rsocket -e 'TCPSocket.new("localhost",8080).close; puts "tcp ok"'
Inspect which host port 8080 is bound to (should be 8080):
- docker inspect -f '{{ (index (index .NetworkSettings.Ports "8080/tcp") 0).HostPort }}' oauth2-mock-oauth2-server-1
Look at server logs for readiness/errors:
- docker logs -n 200 oauth2-mock-oauth2-server-1
On Linux, ensure nothing else is bound to 8080 and that firewall/SELinux aren’t blocking:
- ss -ltnp | grep :8080

Notes

Discovery URL pattern is: http://localhost:8080//.well-known/openid-configuration, where defaults to "default".
You can change these with env vars when running the example:
- E2E_ISSUER_BASE (default: http://localhost:8080)
- E2E_REALM (default: default)
