Dockerfile

[gpasqualetti]

I have been tried to run gpodder2go in a dockerized environment but I have not been fully successful yet. I was wondering if somebody already managed to do it.

This is the Dockerfile I wrote (not working)

# Use a base image
FROM golang:1.16-alpine

ENV VERIFIER_SECRET_KEY='test'
EXPOSE 3005

# Set working directory
WORKDIR /app

# Install dependencies
# Musl-dev is required to fix stdlib.h
RUN apk update && apk add --no-cache wget git gcc musl-dev make sqlite 
RUN apk add --no-cache curl \     
  && curl -L https://github.com/golang-migrate/migrate/releases/download/v4.15.2/migrate.linux-armv7.tar.gz | tar xzv \
  && mv migrate /usr/local/bin/migrate \     
  && apk del curl

# Pull source code
RUN git clone https://github.com/oxtyped/gpodder2go.git /app/gpodder2go

# Make
RUN cd /app/gpodder2go && make build

# Init
RUN cd gpodder2go && ./gpodder2go init

# Run
CMD ["sh", "-c", "echo $VERIFIER_SECRET_KEY && /app/gpodder2go/gpodder2go serve"]

# Create a new user
RUN cd /app/gpodder2go && ./gpodder2go accounts create username --email="myemail@test.com" --name="MyName" --password="mypasswd"

I build and run it with

docker build . -t gpodder2go:latest
docker run -dp 3005:3005 gpodder2go:latest

When I look at the the logs it seems like being starting fine.

2023/04/01 17:30:15 💻 Starting server at localhost:3005

However, when I try to sync with AntennaPod, it sais that the connection failed. Same thing with the gPodder Desktop client. Any hint?

I managed to solve. The problem was the binding to localhost in the CMD command. The following Dockerfile works:

# Use a base image
FROM golang:1.16-alpine

ENV VERIFIER_SECRET_KEY='test'
EXPOSE 3005

# Set working directory
WORKDIR /app

# Install dependencies
# Musl-dev is required to fix stdlib.h
RUN apk update && apk add --no-cache wget git gcc musl-dev make sqlite 
RUN apk add --no-cache curl \     
  && curl -L https://github.com/golang-migrate/migrate/releases/download/v4.15.2/migrate.linux-armv7.tar.gz | tar xzv \
  && mv migrate /usr/local/bin/migrate \     
  && apk del curl

# Pull source code
RUN git clone https://github.com/oxtyped/gpodder2go.git /app/gpodder2go

# Make
RUN cd /app/gpodder2go && make build

# Init
RUN cd gpodder2go && ./gpodder2go init

# Run
CMD ["sh", "-c", "echo $VERIFIER_SECRET_KEY && cd /app/gpodder2go && ./gpodder2go serve -b 0.0.0.0:3005"]

# Create a new user
RUN cd /app/gpodder2go && ./gpodder2go accounts create username --email="myemail@test.com" --name="MyName" --password="mypasswd"

With docker-compose:

version: '3.9'

services:
  gpodder2go:
    container_name: gpodder2go
    build:
      context: ./gpodder2go
      dockerfile: Dockerfile
    ports:       
      - "3005:3005"
    volumes:
      - ./gpodder2go/g2g.db:/app/gpodder2go/g2g.db

It might be necessary to create an empty g2g.db file the first time before mounting.

Maybe it could be worth sharing this info in the documentation.

In case anyone else is having this same issue, I created an automatically updating Docker image with everything setup and working. You can find it here: https://gitlab.com/ConfusedAnt/gpodder2go

Thanks for sharing this!

Note for people using this that as mentioned above which I missed initially you may need to touch g2g.db before running lest docker creates the volume as a directory instead of a file.

You might want to add into your README how you can set the env key and choose a different port.

    ports:
      - 8114:80
    environment:
      - VERIFIER_SECRET_KEY=ETiUYBjkR5qcu

Also, a hint about where the binary is would be helpful:

docker compose exec app /gpodder2go init
docker compose exec app /gpodder2go accounts

Can you build a raspberry pi image? At the moment it reports gpodder2go The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested when I try to run it on my rpi3b.
