Hi Devs,
Based on the previous discussion and decision, I'm in the process of
developing the improvement of the subject as follows,
(1) Publish a new Event called "ArtifactDeploymentCompletedEvent" to the
"instance-notifier" topic of activemq of stratos side by each cartridge
agent upon successful git pull.
(2) Register a listener to the same topic by appfactory and get the event.
(3) Based on the data in the event update the runtime database of
appfactory. (last deployment status of the relevant application)
To complete the above feature based on the logic mentioned, we need the
following data to be published by cartridge agent itself.
(a) tenantdomain
(b) stage (cartridge knows this)
(c) applicationId
(d) applicationVersion
(e) artifactLastModifiedTime
from above data presently only the (b) can be published by cartridge agent.
In the S2 git repo the artifact are represented as separate folders of the
application for each version. (by appending the version info to the folder
name)
Since the (a), (b) and (c) are static to single-tenant cartridge those can
be obtained if we provide those information with cartridge alias (as a
custom formatted string) or manipulating the git repo url.
property (e) also can be obtained for each version-ed artifact folder.
But, the main problem is getting the property (d). Actually we can get the
version info of all the artifacts by its name. But, in cartridge side there
is no way to get the updated artifact list.
One possible solution for this problem is to send all the artifact names
with "lastmodifiedtime" from cartridge side and in appfactory side we can
update the database records which the "lastmodifiedtime" is greater than
the existing db records.
Any comment on this issue is appreciated.
Thanks,
