Creating a Flexget container

Since there isn't an official container image for Flexget, here's a quick how-to on building one your self.

Below is a Dockerfile that creates an image with Flexget that can be used transparently like a normal command.

FROM python:3.9-alpine

ARG FLEXGET_UID
  
# Create a user to run the application
RUN adduser -D -u ${FLEXGET_UID} flexget
WORKDIR /home/flexget

# Flexget config directory.
VOLUME /home/flexget/.flexget
  
# Install build dependencies and FlexGet
RUN apk update && apk add --no-cache gcc g++ linux-headers musl-dev && \
    pip3 install -U pip && pip3 install flexget
  
USER flexget
ENTRYPOINT ["/usr/local/bin/flexget"]

Save the file and build the image with below build command. The flexget user inside the container will get a user ID of 1000. If you're not sure why you should change it, just leave it.

docker build --build-arg FLEXGET_UID=1000 ARG-HERE -t flexget .

# Run example

Run the Flexget container with a config folder mounted.

docker run -v /path/to/config/folder:/home/flexget/.flexget -d flexget daemon start
