Examples¶
Install Emu/PyWPS on localhost¶
Use the WPS playbook:
https://github.com/bird-house/ansible-wps-playbook
Clone the playbook:
$ git clone https://github.com/bird-house/ansible-wps-playbook.git
$ cd ansible-wps-playbook
Optionally you can setup a Vagrant VM for testing:
$ vagrant up --no-provision
$ vagrant ssh
$ sudo yum install epel-release
$ sudo yum install ansible
$ cd /vagrant
Install Emu on localhost (or in Vagrant VM):
$ cp etc/sample-emu.yml custom.yml
$ ansible-playbook -c local -i hosts playbook.yml
This example is using the Emu WPS with simple test processes:
Install Slurm cluster¶
Use this slurm playbook:
https://github.com/agstephens/slurm-playbook
Run playbook with Vagrant:
$ vagrant up
$ ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook -u vagrant --private-key=~/.vagrant.d/insecure_private_key -i inventories/vagrant-cluster.yml playbook.yml
Login to slurm master node:
$ vagrant ssh slurmmaster
Run slurm test:
> sudo -i # become root
> squeue # to view the queue
> sbatch /root/hostname.sh # to run a job
> squeue # to see if it is running
Install Emu/PyWPS on cluster¶
Use the WPS playbook:
https://github.com/bird-house/ansible-wps-playbook
Install PyWPS into the same cluster as slurm:
$ cp etc/vagrant-cluster.yml custom.yml
$ ansible-playbook -u vagrant --private-key=~/.vagrant.d/insecure_private_key -i inventory/vagrant-cluster.yml playbook.yml
This example is using the Emu WPS with simple test processes:
https://github.com/bird-house/emu
Test Emu WPS service¶
Test connection:
http://192.168.50.44:5000/wps?service=WPS&version=1.0.0&request=GetCapabilities
Run “sleep” in async mode with scheduler:
Install the rook/PyWPS for subsetting on cluster¶
This example is using the rook WPS with subsetting processes on climate model data:
Installation is like before with slurm cluster but using a different config file:
$ cp etc/vagrant-cluster-with-rook.yml custom.yml
$ ansible-playbook -u vagrant --private-key=~/.vagrant.d/insecure_private_key -i inventory/vagrant-cluster.yml playbook.yml
In this example demo data is installed in a shared Vagrant folder .local/data

Test rook WPS service¶
Test connection:
http://192.168.50.44:5000/wps?service=WPS&version=1.0.0&request=GetCapabilities
Run “subset” in async mode with scheduler and default values:
