You have to create a new .yaml, let's call it
mymodule.yaml
application: yourapplication
module: mymodule
version: 1
runtime: python27
threadsafe: true
api_version: 1
builtins:
- deferred: on
inbound_services:
- warmup
#instance_class: F2
#automatic_scaling:
# min_idle_instances: 1
# max_idle_instances: 1
# min_pending_latency: 600ms
# max_pending_latency: 2000ms #previously just the max_ one at 900ms [31/05/15]
instance_class: F2 #previously the above version [21/05/17]
automatic_scaling:
min_idle_instances: 0
max_idle_instances: 1
min_pending_latency: 15000ms #max
max_pending_latency: automatic
Then, to deploy, you need to use:
python2.7 ~/appengine-deployer/appcfg.py --no_cookies --noauth_local_webserver --email=your_email update app.yaml mymodule.yaml;
Copy/pasted these from my routine, the GUI way might be different, this is the CLI way
