'Industrial Raspberry PI with portainer.io: file permission issues, app dumped

I've built an image (docker buildx) from an ubuntu 18, stored to tar, uploaded on Portainer (running on RPI)

Using Portainer, I create a stack with yaml file, and I get a "deployment error", but the container is created

Below, the composer file content:

version: '2'
services:
    sda:
        image: <out image>
        network_mode: "host"
        container_name: "sda4"
        volumes:
          - virtual_sda4:/opt/<company>/<application>
        stdin_open: true

Running the container our app is dumped. Connecting with console as root user, listing files has a strange result: all files have "undefined" permissions (question marks instead of rwx) It seems a permission issue.

(*) stdin_open: true: used to keep alive the container, because the app is dumped.

Any idea is appreciated Thanks Lorenzo

Just an update on this topic. The problem was linked to different docker version used for building and deploying the images. The builder was 20., the version on RPI was 18.. Updating the version on RPI, provided by the board integratori, solved the issue.

Hoping this is useful to others. Lorenzo
