[Go-essp-tech] 1.3.0-M2 release available again

[Nathan Wilhelmi]

Hi All,

The M2 release is available again. 
https://vets.development.ucar.edu/nexus/content/repositories/releases/sgf/gateway/1.3.0-M2/

We fixed a database initialization problem uncovered this morning. So 
please download a fresh copy if you downloaded the release prior to 10 
mountain time today.

Based on comments from today's call and e-mails I made a slight change. 
The sample registry document we created initially is now available under 
HTTPS and the upgrade documents have been updated accordingly. The 
gateway simply pulls this file from the configured URL. So the end of 
this can be as simple as a file on disk (file://) or could be a REST 
style web service (https://). As mentioned in the call today the sample 
we put together is a starting point based on the gateways listed on the 
esgf.org wiki.

In this release IDP whitelisting is now driven through the mechanism, so 
you will want to ensure any idps you are trying to use are listed in the 
registry file you are ingesting.

To follow up with a question from earlier today, what happens when the 
registry file/service isn't available?

Out of the box the gateway doesn't ship with any registry information. 
This way it should be relatively easy to use it in a number of contexts, 
no federation, part of the ESG production federation, ESG test 
federation, some other federation, etc...

So if you are using the gateway in a federation it will need to pull 
down the registry information for the first time. Obviously in this case 
the registry file/service will need to be available for this operation 
to succeed.

Once running the regsitry information is stored in the database, if 
file/service becomes unavailable the gateway will continue to operate in 
the last known state. By default the gateway will resync with the 
registry at 00:00 and 12:00 hrs. This can also be triggered manually and 
in M3 the chron experssion can be overridden in the gateway.properties file.

Please let us know if you have any questions or problems

Thanks!
