Or how this site is updated

This site is build via jekyll and the sources are coming from a git repository on github. I do not write something special about git or jekyll here. Just how the “deployment” works.

Github webhook

Github Webhook

Github has a nice feature called “Service hooks” - especially a “Post-Receive URLs” hook. I use this hook to notify my server to do a git pull on a local repository, then rebuild the site with jekyll and rsync changed data to the document root.

The perl webhook endpoint (Dancer.pm code):

package ReceiveHook;
use Dancer ':syntax';
our $VERSION = '0.3';
# Configuration for different projects
my $config = {
    "PROJECTNAME" => {
        run => "/home/user/bin/updateblog.sh",
    },
};
prefix '/notify';
get '/*' => sub {
    header 'Allow' => 'POST';
    status '405';
    "Not for you\n";
};
post '/:project' => sub {
    if (not defined $config->{params->{project}}) {
        status 'not_found';
        return "No such project: ".params->{project}."\n";
    }
    my $payload = params->{'payload'};
    if (not defined $payload) {
        status '415';
        return "I need a payload\n";
    }
    # Read the configuration for that repo
    my $repo_config = $config->{$repo->{name}};
    if (defined $repo_config && defined $repo_config->{run}) {
        eval {
            system $repo_config->{run};
        };
    }
    return "OK";
};
true;

The update itself is done by this little shellscript:

    #!/bin/sh

    REPPATH="/home/user/git/localgitrepository"
    DEPLOYTARGET="/var/www/sites/mydomain"
    LIVEURL="http://mydeploydomain.tld"

    if [ -d ${REPPATH} ] ; then
        cd "${REPPATH}"
        git pull
        jekyll --url "${LIVEURL}"
        rsync -rXogpEAt _site/ "${DEPLOYTARGET}"
    fi

Update (17.12.2016)

I use Hugo now and a different Webhook
