Running locally

Keycloak

If you only want to use preconfigured Keycloak instance just run the run-keycloak.sh script. It will run the Keycloak docker image with the configuration described in the article.
Keycloak realm configuration is present in realm/realm.json file. All additional configuration and customization can be done from there.

Keycloak and Spring Boot

To set up this environment locally just run the deploy.sh script in one of the project directories. It will compile the application and prepare a runnable jar. Then script will run the jar alongside Keycloak docker.

Testing locally

Directory http contains a set of requests in the form of base.http file for IntelliJ build-in HTTP client.

Requests:

1. GET http://localhost:8080/hello
2. POST http://localhost:8090/realms/demo/protocol/openid-connect/token

The request allow for manual testing of the running application.

Only after calling the token request the hello request will return the 200 HTTP code. The first call of a hello request should return a 401 HTTP code.

keycloak-springboot's Issues

Too many redirects

When I try to access http://localhost:8080/hello, I get an error page:

This page isn’t working
localhost redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

Do you have any idea how to fix this? I did clear the cookies but to no avail.
Thanks.
