CILogon Pre-Pilot Work - Jenkins
We used Jenkins together with OpenStack to build an automatically deploying CILogon instance. Jenkins VM Image templates are used to boot VMs with relevant software installed on it, while separate Jenkins jobs are used to carry out different stages of the service deployment. The following sections contain a brief overview of the structure of these Jenkins jobs together with a short description of their function. For more information consult the local jenkins instance.
The Delegation Service is made up of a couple of major components: a myproxy-server, oa4mp server offering an oauth2 frontend to MyProxy, and a Shibboleth SP. Together these components can issue certificates to authenticated users.
The following figure describes the Jenkins jobs used to deploy the Delegation Service:
.------ delegation server -----| certificate-master.inject-hostcert | | Insert a host certificate/key pair into /etc/gridsecurity | | .------ | myproxy-server -----| simple-ca | | | | This task sets up the myproxy-server as a Certificate Authority using | | SimpleCA.

'------ oa4mp.server.approve-clients Automatically approves every pending client registration request.
We used a machine template configured with Shibboleth IdP v3 and Tomcat 7. The machine template installs both shibboleth IdP and tomcat in their default location and takes care of having the right environmental variables set. The jobs used below are meant to be used with this template to further configure the IdP.
