# Bitrise Build Issue Report template

## Description of the issue

I have a build in which I need to run a proprietary Windows executable to generate the final build.

Currently I am able to run this step locally inside a Docker using wine.

However, when I attempt to run the same docker and script in a Bitrise build, the build fails as it is unable to write a file in the mounted volume I add.

## Environment:

**Where did the issue happen?**

Stack:  
Android & Docker, on Ubuntu 16.04.  
Docker with pre-cached Android setup, installed on Ubuntu 16.04.

Dockerfile:  
FROM scottyhardy/docker-wine:latest

```
RUN apt-get update && apt-get install -y zip

WORKDIR /usr/src/app

CMD ["touch test"]

```

Docker image created as:

```
docker run \
  --name test \
  -v "$(pwd)"/app:/usr/src/app/ \
  generate-cap:1.0

```

## Reproducibility

- \_Does a “Rebuild” help? No
- \_Does a rebuild without caches help? No
- _Does the issue happen sporadically, or every time?_ : every time
- _Does upgrading the build Step to the latest version help?_ : no
- _When did the issue start?_ : as soon as I set it up

### Local reproduction

Locally it succeeds.

### Local reproduction: Linux / Android (docker based) stack builds

Locally it succeeds.
