Building a Dockerfile from inside Docker Compose - docker

Question

So I'm trying to follow these instructions:
https://github.com/open-forest/sendy
I'm using Portainer and trying to run a Sendy container (newsletter software). Instead of running a MySQL image with it, I'm just using my external managed database instead.
On my server I keep project data at: /var/docker/project-name. I use this structure for bind mounting if I need to bring data into the containers from the start.
So for this project in the project-name folder I have sendy-6.0.2.zip and this Dockerfile: (This file was provide via the instructions on the above link)

When I try to deploy I get:

Error could not find /data/compose/126/var/docker/project-sendy:

So here's what I've done.
I have the cron and artifacts folder on the same directory as the Dockerfile.
In the Dockerfile look for this line:
COPY artifacts/docker-entrypoint.sh /usr/local/bin/
Right below it put this line:
RUN chmod +x /usr/local/bin/docker-entrypoint.sh
Otherwise you will get this error:
Starting Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/usr/local/bin/docker-entrypoint.sh": permission denied: unknown
Then build it with:
docker build -t sendy:6.0.2 .
Then your image will show up in portainer.
You can then remove the build section in your docker compose file and hit deploy. It now works for me.
