How to create a "Stealth Cloud"

(or how to get your ARCCE to submit to a cloud via a glideinWMS)

1. Setup a glidein WMS, apart from the Submit module which needs to be hosted by the ARCCE.
2. Setup and ARC CE as e.g. described here.
3. On the ARCCE open the necessary ports (and restart iptables)
4. Make a condor user:
   

   [root@cetest02 opt]# groupadd condor
   [root@cetest02 opt]# useradd -m -g condor condor
   [root@cetest02 opt]# passwd -l condor
   

5. Set up the Submit module from the glideinWMS on the ARCCE:
   Note: The versions used on the ARCCE and the glideinWMS have to match ...
   Currently I use condor-8.0.7-x86_64_RedHat6-unstripped.tar.gz and glideinWMS_v3_2_5.tgz
   (as root) glideinWMS_v3_2_5.tgz
   Unpack the glideinwms tarball and set its ownership to something sensible:
   

   [root@cetest02 opt]# tar -zxvf /opt/tarballs/glideinWMS_v3_2_5.tgz; chown -R root:root glideinwms
   

   (as root) /opt/glideinwms/install/manage-glideins --install submit --ini /opt/glideinwms-conf/condor.ini

6. Edit /opt/condor-submit/config.d/03_gwms_local.config to keep an x509 proxy on the WN. At the end add:
   

   use_x509userproxy = True
   SUBMIT_EXPRS = $(SUBMIT_EXPRS) use_x509userproxy
   DELEGATE_JOB_GSI_CREDENTIALS = False
   

   source /opt/condor-submit/condor.sh condor_reconfig

7. Note the comments on /usr/share/arc/Condor.pm on the ARCCE page.
