Resteasy exception when using Keycloak Admin Client

See original GitHub issue

Describe the bug

I’m using the following test code to create a Keycloak testcontainer and get the admin client:

@Testcontainers
public class OrganizationResourceTest {

  @Container KeycloakContainer server = new KeycloakContainer().withContextPath("/auth/").withProviderClassesFrom("target/classes");

  Keycloak getKeycloak() {
    assertTrue(server.isRunning());
    return server.getKeycloakAdminClient();
  }

  @Test
  public void testCreateDeleteOrg() throws Exception {
    Keycloak keycloak = getKeycloak();
    ...

After the containers start up, I get the following error:

[ERROR] io.phasetwo.service.resources.OrganizationResourceTest.testCreateDeleteOrg  Time elapsed: 69.911 s  <<< ERROR!

Your second “issue”, starting multiple containers, is not related to the Keycloak Testcontainers. It’s the way, the Testcontainers work:

You declare your container instance as a class member. In this way, for each test, a new container will be started. If you declare your container as a static class member, then only one container is started and all tests will use this one container. Depending on what you need in your tests (clean and isolated environments or not), the one or the other approach might be the proper one for your. I prefer to start only one container for all of my tests, in most cases.

🤦 I’m just going to do a complete docker reinstall. At least I know it’s something wrong with my setup.
