[google-appengine] Re: Google App Engine: versioning with custom sub domains

[alexander noteboom]

Alex,

We are doing just what you describe, although we do it under the naked 
domain.

we have app.io pointing to appengine, which has a wildcard certificate 
mapped.
My appengine settings for custom domain are like this:

custom domain name | cert | record type | data | alias
*.app.io  | wildcard-certificate |  cname |  ghs.googlehosted.com. |   *
app.io  | wildcard-certificate |  A |  xx.xx.xx.xx |  (none)


all requests for app.io go to the default version.  We also have a release 
candidate version deployed, named 'rc'
Without any configuring all request for rc.app.io go automagically to the 
rc version.

This only works when you have the wildcard certifcate in place.  Just 
adding custom domain mappings for each version will not work.

[google-appengine] Re: Any more migration stories?

[alexander noteboom]

We are in the middle of the migration.  It is a horrible experience.
We tried to break it into small steps. 
Still in python2, we first replaced memcache with redis and  replaced 
search with elasticsearch.  These steps were do-able.

Next we tried to make the python2 code compatible with python3 using 
futurize.  Had a lot of problems with future_builtins and unicode, so we 
futurized except those.


After that we tried to migrate to Cloud Tasks, but that failed horrible 
because of the lack of transactional tasks. Our application heavily relies 
on that.
We thought up a solution, but that required the migration to Cloud ndb. So 
we have to combine these two steps.

That is where we currently are. Fighting with Cloud Tasks, Cloud NDB, 
namespaces, and getting it running using python3 on a local machine.
The most annoying thing is that there is no local Task Emulator available, 
and no Datastore Emulator viewer available.
