+title: A new hosting for this blog

+description: This blog is now self-hosted

+<!--excerpt_start-->
+Migrating from [GitLab Pages](https://docs.gitlab.com/ee/user/project/pages/) (or *put any name here*) to a private webserver has one main advantage: to be in control of *all its data*.
+<!--excerpt_end-->
+
+## Problems
+
+You have most certainly read or heard that self-hosting a website is a very bad idea because:
+
+- it might pose security risks
+- it is unreliable
+- it is hard to maintain
+- etc...
+
+and all of that is true. For this specific website I don't care. It is *just* a blog...
+
+## Howtos
+
+Up until now I used a system called [Gitlab CI/CD](https://docs.gitlab.com/ee/ci/). Every time I committed to the git repository
+a Docker worker would rebuild the website. That usually took from 3 to 5 minutes!
+
+Since this website is generated using [Jekyll](https://jekyllrb.com/)
+I followed [this guide](https://jekyllrb.com/docs/deployment/automated/#git-post-receive-hook) but
+created a new file called `hooks/post-receive` which is a little different to the one in the tutorial:
+
+```shell

+
+# Install Ruby Gems to ~/gems
+export GEM_HOME=$HOME/gems
+export PATH=$GEM_HOME/bin:$PATH
+
+TMP_GIT_CLONE=$HOME/tmp/myrepo
+GEMFILE=$TMP_GIT_CLONE/Gemfile
+PUBLIC_WWW=/var/www/blog.frnmst.duckdns.org
+
+git clone $GIT_DIR $TMP_GIT_CLONE
+BUNDLE_GEMFILE=$GEMFILE bundle install
+BUNDLE_GEMFILE=$GEMFILE bundle exec jekyll build --trace --strict_front_matter --verbose --safe -t -s $TMP_GIT_CLONE -d $PUBLIC_WWW
+rm -Rf $TMP_GIT_CLONE
+exit
+```
+
+Moreover, before running that git hook:
+
+1. install ruby: `apt-get install ruby ruby-dev`
+2. login as the deploy user
+3. add this to its `~/.profile`:
+
+   ```shell
+   export GEM_HOME="$(ruby -e 'puts Gem.user_dir')"
+   export PATH="$PATH:$GEM_HOME/bin"
+   ```
+
+4. install bundle: `gem install bundle`
+
+That's it.
