> Key: IGNITE-29164
> URL: https://issues.apache.org/jira/browse/IGNITE-29164
> Project: Ignite
> Issue Type: Task
> Reporter: Maksim Davydov
> Assignee: Maksim Davydov
> Priority: Minor
> Fix For: 2.19
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> On a rootless Docker daemon, docker/run_tests.sh fails before the first test:
> ducktape gets PermissionError writing .ducktape/metadata/session_id into the
> checkout mounted at /opt/ignite-dev.
> The image creates the ducker user with the caller's host uid (IGNITE-27445),
> but a rootless daemon maps only container uid 0 to the caller, so ducker
> cannot write the mount. The fix makes ducker-ignite detect a rootless daemon
> through docker info and build ducker as uid 0, which has the caller's rights
> on the host and no more; rootful builds are unchanged. The README notes that
> network fault tests on a rootless daemon need the iptables and sch_netem
> kernel modules loaded on the host.
