testcontainers don't work with Jenkins running on docker

[jelbatnigi]

It seems that when running a JdbcDatabaseContainer inside a dockerized Jenkins things don't work.
I have an integration test that required to spin up a postgres testcontainer. Everything runs fine when I run it locally.
But when I run my integrationtest as part of my build in jenkins. first I get
Could not connect to Ryuk at 172.17.0.1:xxxx
I figured this is because the way I am running my Jenkins container I have to expose all ports since Ryuk runs on a random port.
I reran my Jenkins container using
docker run --network=host
That resolved the Ryuk error even through running with --networ=host I couldn't access Jenkins on port 8080 for some reason. But with that when I run my integration test I now get
Connection to localhost:5432 refused which basically the I cannot connect to the postgres test container
So I can't really find a way to get this to work. The bottom line is I cannot run testcontainers inside another container or specifically inside a Jenkins container.

this is how I initialize my testcontainer:
@Container public static JdbcDatabaseContainer container = (JdbcDatabaseContainer) new PostgreSQLContainer(DB_TEST_CONTAINER_NAME).withDatabaseName(DB_TEST_CONTAINER_DB_NAME) .withUsername(DB_TEST_CONTAINER_USER).withPassword(DB_TEST_CONTAINER_PASSWORD).withInitScript("db/migration/create_dba_role.sql");
Any idea or feed back I will appreciate it.

Hi @jelbatnigi I think this is still related to #6584 I would appreciate if you can share your findings in the same discussion. Thanks in advance.
