Permission Denied When Using Bash Script in Published Shiny App

Hi all, I have a problem here related to permission denied when shiny app called bash script under system2 function in published shiny app.

My Rstudio was running on docker container from rocker/verse image where software package (PLINK1.9 and Vcftools) using in bash script was subsequently installed in this containter by

docker exec -it <container name> bin/bash.
sudo apt-get install <package name>

Locally, my shiny app can successfully run and accomplish task in this container but permission denied issue was occurred when it was published in

This problem was still occurred even though the permission was set up by using chmod u+x

This is what my shiny log report

2019-12-14T08:36:51.516457+00:00 shinyapps[1535766]: sh: 1: code/bash_script/ Permission denied

Is there any solution to fix this problem ?
