The agent is responsible for post-processing on uploaded content, it executes a wsgi app that can be used to download the digital objects.
export CQLENG_ALLOW_SCHEMA_MANAGEMENT=1
export DRASTIC_SCHEMA=/path/to/schema.json
export AGENT_CONFIG=/path/to/agentconfig
This can be added in the file /etc/init/drastic-agent.conf to be configured
when the agent is launched by upstart
env CQLENG_ALLOW_SCHEMA_MANAGEMENT=1
env AGENT_CONFIG=/usr/lib/drastic/agent/project/agent.config
This is an example of a configuration file that you can use to define where the agent is looking for the root of the archive on the filesystem (path defined with AGENT_CONFIG environment variable).
DISK_CONFIG = { 'ROOT': '/data' }
The agent is managed by upstart, it should be configured automatically when deployed. It can be run with the command
sudo service drastic-agent start
Agent is listening on port 9000
http://localhost:9000/
It provides an internal API used by drastic to download files managed by the
agent driver, for instance the URL http://localhost:9000/get/test/test.txt will try
to download the file /data/test/test.txt on the file system.
