Hi all, new to the forum and to Jekyll.

I am running Jekyll in a Docker container on Ubuntu 22.04 LTS.

Here are my logs:

fatal: not a git repository (or any parent up to mount point /srv)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

Accessing localhost:4000 in Firefox tells me that my browser cannot establish a connection.

Typing in sudo lsof -i :4000 doesn’t bring up anything else on that port.

I can find the IP address of my container, and putting in :4000 gives me an error that my request has timed out.

I can grab the contents of an HTML file and display them in the terminal, so something can see them, it’s just not serving them.

Could you show the Docker command? In particular the -p or --publish flag, which would control how container ports are exposed.

3

Have you tried to point your browser to http://container_ip/ without the :4000 port?

Thanks for replies, both, sorry for the wait.

docker-compose.yaml looks like this:

  jekyll:
    container_name: $NAME_jekyll
    build:
      context: .
      dockerfile: jekyll.Dockerfile
    ports:
      - "4000:4000"
    volumes:
      - ./srv:/srv/jekyll
    stdin_open: true
    tty: true
    command: /bin/bash

dockerfile looks like this:


FROM ruby:3.3.5-bookworm

RUN <<EOF
    apt-get update
    apt-get upgrade -y
    apt-get install -y --no-install-recommends \
        nano
    apt-get clean
    rm -rf /var/lib/apt/lists/*
EOF

RUN gem install jekyll -v 4.3.4 && gem install bundler

WORKDIR /srv/jekyll

EXPOSE 4000

and to run it all I use a script that does this:


docker compose build --no-cache jekyll
docker compose run jekyll bash
5

By default the docker compose run command does not setup the networking, so you’d need to add --service-ports. For example (tested):

$ docker compose run --service-ports jekyll bash
root@b876583518e4:/srv/jekyll# jekyll serve -H 0.0.0.0

This fixed it for me. Thank you so much!
