Signing News and Hosting a News Server with Docker

i2p.newsxml has two containers, one for hosting the news itself, and one which is used for running news.sh and generate_news.py in a container on Linux distributions where Python2 support is limited or unavailable. It's also useful if you simply prefer to manage Docker containers using Docker's or related project's tooling(Portainer or sen for instance).

To build the signing container, use:

docker build --no-cache -t i2p.newsxml.signing -f Dockerfile.signing .

To run news.sh in the container, prepare your etc/su3.vars.custom.docker file as if your signing keys directory were mounted at /.i2p-plugin-keys. No other differences should be required between a Docker and non-docker news.sh run

docker run -it \
  -u $(id -u):$(id -g) \
  --name i2p.newsxml.signing \
  -v $HOME/.i2p-plugin-keys/:/.i2p-plugin-keys/:ro \
  -v $HOME/i2p/:/i2p/:ro \
  i2p.newsxml.signing

Then, extract the built feeds from the container:

docker cp i2p.newsxml.signing:/opt/i2p.newsxml/build build
docker build --no-cache -t i2p.newsxml.signing -f Dockerfile.signing .
docker rm -f i2p.newsxml.signing
docker run -it \
  -u $(id -u):$(id -g) \
  --name i2p.newsxml.signing \
  -v $HOME/.i2p-plugin-keys/:/.i2p-plugin-keys/:ro \
  -v $HOME/i2p/:/i2p/:ro \
  i2p.newsxml.signing
docker cp i2p.newsxml.signing:/opt/i2p.newsxml/build build

Now, you're ready to build the hosting container:

With the feeds in build from the previous step, run:

docker build -t i2p.newsxml .

then, to serve the files on a local port:

docker run -d --restart=always --name newsxml -p 127.0.0.1:3000:3000 i2p.newsxml
docker build -t i2p.newsxml .
docker rm -f newsxml
docker run -d --restart=always --name newsxml -p 127.0.0.1:3000:3000 i2p.newsxml
