The `--rootless` flag had a couple of issues: * #38702: euid=0, $USER="root" but no access to cgroup ("rootful" Docker in rootless Docker) * #39009: euid=0 but $USER="docker" (rootful boot2docker) To fix #38702, XDG dirs are ignored as in rootful Docker, unless the dockerd is directly running under RootlessKit namespaces. RootlessKit detection is implemented by checking whether `$ROOTLESSKIT_STATE_DIR` is set. To fix #39009, the non-robust `$USER` check is now completely removed. The entire logic can be illustrated as follows: ``` withRootlessKit := getenv("ROOTLESSKIT_STATE_DIR") rootlessMode := withRootlessKit || cliFlag("--rootless") honorXDG := withRootlessKit useRootlessKitDockerProxy := withRootlessKit removeCgroupSpec := rootlessMode adjustOOMScoreAdj := rootlessMode ``` Close #39024 Fix #38702 #39009 Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp> |
