I'm running Sysbox 0.6.2 release with docker locally.
I'm currently trying to increase /etc/subuid subordinate range for sysbox, since I want to try to run Podman inside system container.
Linux version:
$ uname -a
Linux mdev 6.2.0-35-generic #35~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Oct 6 10:23:26 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Is this expected or there's something on my part here which I didn't understand correctly how it works?
Should the given range inside container when cat /proc/self/uid_map be 100000 instead of 65536?
I've read docs and it says that with sysbox-mgr is possible to change this available range, but I couldn't find the right option for it.
Thanks!

Yes, it's expected; Sysbox assigns UIDs to the containers from the range it configures for user sysbox in /etc/subuid. In your scenario, looks like /etc/subuid is configured for user sysbox as follows:
sysbox:165539:100000
Therefore, it will map the UIDs in the container as follows:
Container UID
Host UID
0
165539
1
165540
2
165541
..
65535
231074
Note: in the Sysbox Community Edition, it always assigns the same UID range to all containers. Same applies to GIDs.
Hi all,
I'm running Sysbox 0.6.2 release with docker locally.
I'm currently trying to increase
/etc/subuid
subordinate range for sysbox, since I want to try to run Podman inside system container.Linux version:
Output of /etc/subuid and /etc/subgid
When running docker container with following command:
$ docker run --runtime=sysbox-runc -it --rm --name=podman podman:v1
And executing inside the container:
