Description
Description
I found dockerd-rootless-setuptool.sh exited with no messages. For example, run check command.
$ dockerd-rootless-setuptool.sh check
$ echo $?
1
It seems a bug caused by #49036 . Unfortunately, dockerd-rootless-setuptool.sh sets -eu options.
set -euThe below commands exit immediately when the status code is not zero.
getsubids "$USERNAME" > /dev/null 2>&1 || getsubids "$(id -u)" > /dev/null 2>&1or
grep -q "^$USERNAME_ESCAPED:\|^$(id -u):" /etc/subuid 2> /dev/nullReproduce
- remove target subuid/subgid entries in /etc/subuid (/etc/subgid)
- get latest dockerd-rootless-setuptool.sh after Use
getsubidstool for subid validation if possible #49036- I installed docker-ce-rootless-extras-28.0.4-1.el9.x86_64
- dockerd-rootless-setuptool.sh check
Expected behavior
The previous dockerd-rootless-setuptool.sh shows the following messages when the subuid/subgid entry is not found.
$ dockerd-rootless-setuptool.sh check
[ERROR] Missing system requirements. Run the following commands to
[ERROR] install the requirements and run this tool again.
