p_install_processing_server.yml

---
#
# Purpose of this playbook is to prepare running ocrd processing server with
# ocrd-webapi-implementation to the VM. It can be logically divided into 3 parts:
# 1. Generall tasks like installing needed software, add ssh-keys for developers and uploading
#    scripts for maintanance
# 2. Preparing to run processing server and webapi: copy files and scripts, create folder for
#    volume-mount
# 3. Installing ocrd and processors to a venv: The processing server runs in Docker and deploys
#    the processors to the host system. Therefore a venv is used wich is installed via ocrd_all
#
- hosts: ocrd-dev
