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
#!/bin/bash -l

# 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.
