Keycloak changed the health endpoint to a separate "management port" starting version 25.0.0 as can be read in the changelogs.
The keycloak module in testcontainers-python uses this endpoint for the readiness_probe. Currently compatibility with Keycloak >= 25 is broken.
This MR adds compatibility with Keycloak >= 25 by changing the readiness probe to do the following:
An alternative approach would have been to create a separate LegacyKeycloakContainer class as has been done in other modules, however I think this unnecessarily complicates the user experience.
Additionally a public
get_management_urlmethod has been added to give end-users convenient access to the new Keycloak management endpoint.
