1. Make sure that containers created are stopped and removed. This is done by using a predefined test_busybox container name, which is getting removed in teardown_busybox. 2. Fix space at EOL. Signed-off-by: Kir Kolyshkin <[email protected]>
Easier to read mounts. No functional change. Signed-off-by: Kir Kolyshkin <[email protected]>
In case a tmpfs mount path contains absolute symlinks, runc errors out because those symlinks are resolved in the host (rather than container) filesystem scope. The fix is similar to that for bind mounts -- resolve the destination in container rootfs scope using securejoin, and use the resolved path. A simple integration test case is added to prevent future regressions. Fixes opencontainers#2683. Signed-off-by: Kir Kolyshkin <[email protected]>
