RHCSA EX200 v8k Exam experience

Hi Everyone,

i attempted the RHCSA v8k (EX200) exam and passed luckily, but still doubtful about the container question, which was very simple. 

i tried but command was not succesful, and not even on my laptop VMs (RHEL8.0 and 8.2),  but i tried the same successfully on RHEL 8.4, 8.6 and even on RHEL9.

so , still confused why this happened, is it a bug or wrong underline platfrom to test the exam objective.

 

Thanks,
Rehmat Ali

Hello, let us refrain from talking about exam content, but let us focus on the "podman"/"container" error you are facing, could you reproduce the error command on your local machine eg on Fedora/RHEL? If yes, what error is it? Are you sure you are not forget about SELINUX Context for the container folder (container_t)? and are you sure that you already map the subiud and subguid like on podman documentation?

 

I will remind again, let us talk about those, if you sure you can share more information regarding your problem, I will be happy to reply, as we all in RHCSA are bound by NDA, but here we can still talk about the exercise or the course content. Thanks.

i have done these steps, and rootless container was not running after reboot.

 

# vi /etc/systemd/journal.conf --> (Storage=persistent)
$ sudo systemctl restart systemd-journald
# setsebool -P container_manage_cgroup on
$ mkdir /home/user1/container_journal
$ mkdir /home/user1/.config/systemd/user
$ chown -R user1:user1 /home/user1/.config
-
$ podman login registry.redhat.io
$ podman pull registry.redhat.io/rhel8/rsyslog-custom-cert
$ cd /home/user1/.config/systemd/user
$ podman run -d --name logserver -v /home/user1/container_journal:/var/log/journal:Z rhel8/rsyslog
------------------------------------------
$ vi .bashrc
export XDG_RUNTIME_DIR=/run/user/$(id -u)
export DBUS_SESSION_BUS_ADDRESS=unix:path=${XDG_RUNTIME_DIR}/bus
$ source .bashrc


$ podman generate systemd --files --name logserver
$ loginctl enable-linger user1
$ loginctl show-user user1
$ podman stop logserver (do not remove container)
$ systemctl --user daemon-reload
$ systemctl --user enable --now container-logserver.service
$ podman ps -a
$ sudo reboot
$ pdoman ps -

Have you check the podman logs logserver?

 

2nd have you check systemctl --user status container-logserver.service?

 

there are another type of flags on podman generate systemd https://docs.podman.io/en/latest/markdown/podman-generate-systemd.1.html

 

Should be --new... you should check it.

Hello @RehmatAli !

I hope you're fine. 

Unfortunately, we cannot provide any assistance due to the NDA agreement. 

You can request an exam review by sending an email to certification-team@redhat.com If you have any concerns about your attempt.

 

Kind Regards, 

Fabio
