fn create context container-registry ?

[Arvinzhu]

Deploying first app
In first place please create a new Fn CLI context for the particular deployment:

fn create context distributed-fn --registry <container-registry> --api-url http://api.fn.local:8080
fn use context distributed-fn

Who can tell me what's the --registry <container-registry> means ?
I think --registry <container-registry> means docker hub registry , so I set value http://f1361db2.m.daocloud.io but it semms not current.

[root@localhost pyfn]# fn -v deploy --app testapp
Deploying pyfn to app: testapp
Bumped to version 0.0.2
Building image http://f1361db2.m.daocloud.io/pyfn:0.0.2 
FN_REGISTRY:  http://f1361db2.m.daocloud.io
Current Context:  distributed-fn
invalid argument "http://f1361db2.m.daocloud.io/pyfn:0.0.2" for "-t, --tag" flag: invalid reference format
See 'docker build --help'.

Could someone tell me how to deal with this problem ?

Hi Arvinzhu,

Thanks for trying out Fn. I think you have the value mostly right, however, I don't think you include the "http://" in the registry value.

As an example, I am gonna a refer to an example on the Oracle Functions Quickstart site.

In this example the service defines the structure for their registry value as:
fn update context registry <region-code>.ocir.io/<tenancy-namespace>/<repo-name>

which results in this for a command:
fn update context registry phx.ocir.io/ansh81vru1zp/acme-repo

For Docker hub, I believe you just use your docker hub username, for example:
fn update context registry your-username-here

From the data you provided it looks like you are using a different service so your mileage may vary. But I would try removing the "http://" protocol specification from the host name and path and see if that works.

Let me know how it goes.
