Installation

Starting your VM

cd metacpan/metacpan-developer vagrant up vagrant ssh

Just become metacpan

For almost everything, you'll be better off as the metacpan user

So, "sudo su metacpan" whenever you start an SSH session

Running web tests

sudo su metacpan cd ~/metacpan.org prove -lvr t

Running api tests # run Elasticsearch in the foreground # you don't have to stop elasticsearch, but it saves some resources

vagrant ssh sudo /etc/init.d/elasticsearch stop sudo /opt/elasticsearch-0.20.2/bin/elasticsearch -f \ -Des.http.port=9900 -Des.cluster.name=testing

# log in with a new session to run the tests # don't pass the -r flag to prove vagrant ssh sudo su metacpan cd ~/api.metacpan.org source ~/.metacpanrc prove -lv t

Restarting Services /etc/init.d/metacpan-www restart /etc/init.d/metacpan-api restart

# if you're running the api locally sudo /etc/init.d/elasticsearch restart

# if you're indexing the full CPAN # and want to watch for the latest changes sudo /etc/init.d/metacpan-watcher start

Vagrant Workflow

Edit files on the host

Run tests and deploy code on the guest

Playing with Puppet # on the host, in the dev directory you created cd metacpan/metacpan-puppet # let's add a new binary (ncdu) to the system vi modules/metacpan/manifests/packages.pp

package { ncdu: ensure => present }

cd ../../metacpan-developer vagrant provision
