Memory Spills

Memory Spills is a blog based on Jeykll and hosted on GitHub.

Useful commands

Set up local test envrionment

TLDR: run docker-compose up in a console and preview the blog at http://localhost:8000/ with a browser.

Docker-based environment

The easiest way to have a local test envrionment up and running is executing this command in a Linux or macOS console:

docker-compose up

This will install all dependencies and bring up a test web server, all in a Docker container. If everything works, the following messages are displayed in the console:

jekyll_1  |     Server address: http://0.0.0.0:8000/
jekyll_1  |   Server running... press ctrl-c to stop.

The blog site is available for preview at http://localhost:8000/ .

If for whatever reason docker-compose is not wanted, the following manual steps can achieve the same effect.

Build the image:

docker build . -t docker-github-pages

Start the container serving the static site:

docker run -it -v "$PWD":/usr/src/app -p 8000:8000 docker-github-pages

Run a single command:

docker run -it -v "$PWD":/usr/src/app -p 8000:8000 docker-github-pages bundle exec github-pages versions

Host-based environment

One-liner to set up the environment:

curl -sSL https://rvm.io/mpapis.asc | gpg --import - \
&& curl -L get.rvm.io | bash -s stable \
&& bash -l -c 'source /etc/profile.d/rvm.sh \
&& rvm reload \
&& rvm requirements run \
&& rvm install 2.5.3 \
&& rvm use 2.5.3 --default \
&& gem install jekyll bundler sass'

Test locally:

bundle exec jekyll serve --port 8000 --host 0.0.0.0 --drafts
