Test of Testcontainers.exposeHostPorts: https://www.testcontainers.org/features/networking/#exposing-host-ports-to-the-container
The test is: src/test/java/CurlToHostTest.java
To run against docker: ./test-docker.sh The test should pass.
To run against podman: ./test-podman.sh As of podman 3.2.0-rc1, the test fails. Looking at the stdout of the failing test, the reason for the failure is:
[main] ERROR 🐳 [curlimages/curl:7.76.0] - Log output from the failed container:
curl: (6) Could not resolve host: host.testcontainers.internal
