Docker based setup for self hosting

[accforgithubtest]

Hello there

A docker compose based set up might be the most ideal option for selfhosting. Would be great if there is a

1. Image on dockherhub / etc, prebuilt for all platforms.
2. Detailed instructions with a sample example file.
3. Provide a single config / file that can be volume mounted for configuring the list of RSS feeds.
4. Environment variables for configuring refresh frequency, etc.

Thank you for this project!

If it helps, here's my recent experience on this topic:

• There is already an unofficial (?) image on dockerhub: https://hub.docker.com/r/arsfeld/yarr
• The default etc/dockerfile runs make build_linux which assumes it's compiling for amd64. If you're using an arm64 device, e.g. a Raspberry Pi, then you'll need to run make build_default instead.
• There's currently an issue with compiling go-sqlite3 on the latest Go 1.21.5 Alpine docker image (used by the above Dockerfile). Adding -D_LARGEFILE64_SOURCE to the CGO_CFLAGS environment variable is a temporary fix. For further information, see: Fix musl build (#1164) mattn/go-sqlite3#1177
• You can already import/export an OPML file with the list of RSS feeds from the web interface, if that helps.

@nkanaev I'm happy to raise a PR to add this to the docs if you like.

I ended up with the following Dockerfile:

FROM golang:1.21.5-alpine AS build
RUN apk add --no-cache build-base git

WORKDIR /src
RUN git clone https://github.com/nkanaev/yarr.git .
ENV CGO_CFLAGS="-D_LARGEFILE64_SOURCE"
RUN make build_default

FROM alpine:3.19
COPY --from=build /src/_output/yarr /usr/local/bin/yarr
RUN mkdir /data
CMD ["/usr/local/bin/yarr", "-addr", "0.0.0.0:7070", "-db", "/data/yarr.db"]

I'm running yarr behind Caddy with Tailscale HTTPS, so my docker-compose.yml file is a bit more complicated, but a basic example might look like this, assuming it's in the same directory as the Dockerfile and that you've also created a sub-directory called data:

version: "3"

services:
  yarr:
    build:
      context: .
    ports:
      - 7070:7070
    volumes:
      - ./data:/data

Hello, I forked a repository called rebron1900/yarr and made some small improvements.

I want to publish it to Docker Hub using Action, but I encountered an error while running it. After my investigation, I found that the master branch and tag branch of the original author have different file structures. How did they manage to do that?

How can I make it run properly?

[rebron1900]

@grabpot thks，I have successfully packaged my own Docker image.

Would be great if we could add a GitHub Actions workflow to this repository in order to publish an official image automatically on releases.

Here are the docs.

@rebron1900 I just saw your workflow at https://github.com/rebron1900/yarr/blob/master/.github/workflows/build-docker-image. Maybe do you want to create a PR to this repository?

Yes, this workflow works really well. And I've also added support for one -click subscription to yarr through Rsshub radar.
Of course, I'm willing to do that. I will try to submit a pull request for the master branch later.
