After i builded the Container everything run as expected. Except the gs-server Part is not enabled. Maybe we could start gs-server on Container Runtime

[Fusl]

@localleon The gs-server runs with the same image but in another container, so:

To start the gs-server:

docker container run -d -p 29000:29000 --restart=unless-stopped --entrypoint gs-server IMAGENAME

And each grab-site job runs in its own Docker container:

docker container run --rm -d -e GRAB_SITE_HOST=172.17.0.1 --name "grab-site_$(cat /proc/sys/kernel/random/uuid)" -v /data:/data:rw IMAGENAME --igon --import-ignores /data/ignores URL

@Fusl Now I understand, works great. This pull request should make some changes to the readme to explain how to use the dockerfile.

For me, this bombs out when I try to do a docker build with:

      gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -DTHREAD_STACK_SIZE=0x100000 -fPIC -DUSE__THREAD -DHAVE_SYNC_SYNCHRONIZE -I/usr/include/ffi -I/usr/include/libffi -I/usr/local/include/python3.9 -c c/_cffi_backend.c -o build/temp.linux-x86_64-3.9/c/_cffi_backend.o

It looks like we do need to force Python version 3.7.9 here. So, try this instead:

FROM python:3.7.9-alpine
