Hello, team!

Faced with the next situation.

For test proposes install next apps on the plc.

Also, via ssh check the state of podman containers.

And it work fine. But after reboot of the plc, WBM indicates that apps are ok and run, but podman ps return blank container list, and actually no response from the apps via dedicated ports...

If take a look at plcnextapp.log there is no errors or warnings

How can be fixed?

    It has not been possible to reproduce this behaviour.

    Here are the steps that were taken:

    • AXC F 2152 with a factory default file system and firmware version 2023.6
    • Install four container-type apps, as shown below:

    • Reboot the controller.
    • Open an ssh session on the controller, log in as root, and check the state of the containers:

    All containers appear to have restarted successfully.

    What other steps should be taken to reproduce the behaviour you are seeing?

    Hello Oleksandr,

    additionaly maybe check

    "podman container ls -a"

    to see the status of the containers and if they were started (but crashed for some reason at boot.)


    You can also check the container logs additionaly via podman if thats the case.

    Dear Martin, dear Oliver.

    As I find out, the plc I was received for test proposes, previously was under heavy duty of different software experiments. One of them was to install apt package wrap. So, there was some troubles and collisions in packages versions of fw, which was leaved unresolved, and some packages replace original one with different versions. So the fact that plc could operate was a surprise for me. Actually in case of IDE interact there was no any troubles met. That's why I does not recognize source of issue at once.

    After plc recovery 2 with next update to fw 2023.6, the problem have gone.

    I should clear fw before any operations. As a result signal to you irrelevant issue...

    Best regards.
