This is my YAML file for GitHub Actions

name: Windows Install

on: 
  workflow_dispatch: {}

jobs:
    makeWindowsInstaller:
        name: "Make Install"
        runs-on: ubuntu-latest
        steps:
          - name: "Working"
            run: |
              mkdir working
              chmod 777 working
              cd working
              curl https://MYSERVER/files.zip -L -o files.zip
              curl https://MYSERVER/wizard.iss -L -o wizard.iss
              unzip files.zip
              mkdir Output
              docker run --rm -i -v "$PWD:/work" amake/innosetup wizard.iss  

Who can deal with this problem, and how can I solve it?

There is a workaround #7 (comment)

[miurahr]

My workaround is "mkdir -p build && chmod -R a+w build" and "umask a+w " before the job.

I find one of causes of the issue.
When I run the container as "rootless" mode, container users and host users are mapped using subuid.

username	uid/gid in guest	uid/gid on host
root	0.0	1000.1000
xclient	1001.1000	100999.100999

When you call the "Output" folder as ordinary permissions not to allow other users, it failed to write a file.
The workaround is "chmod 777 Output".
It will run successfully but the next time you want to clean the "Output" folder, you will got permission error, because the target file is owned by user who has 100999.100999 user.

@amake

Could you update the image to run the following script as the entry point ?

#!/bin/bash
set -e
TARGET=$(dirname -- "${!#}")
env HOME=/home/xclient WINEPREFIX=/home/xclient/.wine WINEARCH=win32 iscc $@
# Find and chmod files generated by iscc
find /work/${TARGET}/ -type f -user "$(whoami)" -exec chmod 777 {} \;

It assumes the last parameter is a relpath of the target ISS and a parent directory has a permission "0777".
