Core

Testcontainers version

1.19.8

Using the latest Testcontainers version?

Yes

Host OS

Ubuntu 22.04.4 LTS

Host Arch

x86

Docker version

26.1.4

What happened?

Using the following statement:

new GenericContainer<>("...")
  ...
  .withFileSystemBind("...", "...", BindMode.READ_WRITE)
  ...;

creates a root:root directory/file while executed by a normal, non-root user.

Is there any way to avoid that and to create directories/files owned by the current user ?

You have to specify host user to have non-root owner of the files.

I have create test example with description here https://github.com/bedla/testcontainers-created-host-file-owner .

TLDR; Just use GenericContainer.withCreateContainerCmdModifier({ cmd -> cmd.withUser("1000:1000") }) and you will be ok. See https://github.com/bedla/testcontainers-created-host-file-owner/blob/master/src/test/kotlin/cz/publicstaticvoidmain/reproduce/tccreatedhostfileowner/MyApplicationTest.kt file for TC details.
