Python-Glancepush

Python-Glancepush is an implementation of glancepush using the native libraries of OpenStack. This work is based in the original implementation of Mattieu Puel. You can find the original implementation here.

Installation Instructions

You have 3 options:

  • Clone this repository. After that, go into cloned directory and execute "python setup.py install"
  • Download it from Releases page
  • Download it from yokel.org. Thanks to Owen Synge

Usage

First of all, you will need /etc/keystone/voms.json, the file which maps VO's and tenants. Copy it to /etc/glancepush/voms.json

This software will use the same files that glancepush (/var/spool/, /etc/glancepush/meta)

You'll need to create some files in clouds directory. You'll need a file per site and VO (tenant). For example if your site is some_site and you have in your voms.json the following:

{
"fedcloud.egi.eu": {
    "tenant": "egi"
},
"ops": {
    "tenant": "ops"
},
"biomed.eu": {
    "tenant": "biomed"
},
"dteam": {
    "tenant": "dteam"
}
   }

Create two files, one for fedcloud.egi.eu, and another one for biomed.eu following this structure:

[general]
# Tenant for this VO. Must match the tenant defined in voms.json file
testing_tenant=egi
# Identity service endpoint (Keystone)
endpoint_url=https://server4-eupt.unizar.es:5000/v2.0
# User Password
password=123456
# User
username=John
# Set this to true if you're NOT using self-signed certificates
is_secure=True
# SSH private key that will be used to perform policy checks (to be done)
ssh_key=Carlos_lxbifi81
# WARNING: Only define the next variable if you're going to need it. Otherwise you may encounter problems
cacert=path_to_your_cert

Finally, just run glancepush.py (python glancepush.py)

TO-DO

  • Add policy checks
  • Clear /var/spool/glancepush directory after uploading images (it's this neccesary?)
  • Clear /tmp after uploading
