I would know something about fiware-glancesync component. I would like to synchronise only one image. I mean, I want to synchronise one single image in a region without modifying the current configuration file. How can I define a new configuration parameters (if it is possible) to do it with the GlanceSync?
The algorithm used to select the images can be defined by the user. The easiest and best way to suncrhonise only one or a set of images is modifying the glancesync.conf configuration file inside ./conf directory. I recomend the creation of a new section [test] in order that you do not modify the current [master] section. Just write the following lines:
[test]
metadata_condition = image.name == 'GIS_GE'
credential= admin,<your secret>,http://130.206.112.3:5000/v2.0,admin
Keep in mind that '130.206.112.3' is the IP of the keystone service inside the FIWARE Lab, and the first and second admin are the OS_USERNAME and OS_TENANT_NAME. Last but not least 'your secret' is the password in base64 format.
And then, only execute the command:
./sync.py test:<name of the node, e.g. Lannion2>
See documentation in GlanceSync - Glance Synchronization Component in order to know more details about the image synchronization.
If you can obtain more information about the configuration of the GlanceSync, take a look to GlanceSync Configuration.
