研究方向

從日誌中顯示的 DockerClientFactory 以及 UnixSocketClientProviderStrategy 和 DockerDesktopClientProviderStrategy 項目著手。在設定 DOCKER_HOST 和 TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE 的情況下重現 PostgreSQL 整合測試,然後追蹤 Podman socket 被忽略的原因。完成的標準是 Testcontainers 2.0.2 採用已設定的 socket,且整合測試能夠成功啟動。

What happened?

Sorry if this is a duplicate, I wasn't able to find this issue.

I've been using Podman without any issues with the 1.x release series for years now following instructions like these. However it seems these environment variables are not respected anymore, because after upgrading some of our projects to Spring Boot 4 (which includes tc 2.0) I can't run integration tests anymore. Even after setting the following environment variables it still fails with the same message looking for /var/run/docker.sock, so something seems to be off:

DOCKER_HOST=unix:///run/user/1000/podman/podman.sock
TESTCONTAINERS_RYUK_DISABLED=true
TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE=unix:///run/user/1000/podman/podman.sock
