Deploy the "get" function with an HTTP trigger:
```
 gcloud functions deploy get --runtime [YOUR_RUNTIME] --trigger-http
```
- Replace [YOUR_RUNTIME] with the name of the runtime you are using. For a complete list, see the gcloud reference.

Deploy the "set" function with an HTTP trigger:

 gcloud functions deploy set --runtime [YOUR_RUNTIME] --trigger-http

Deploy the "del" function with an HTTP trigger:

 gcloud functions deploy del --runtime [YOUR_RUNTIME] --trigger-http

Call the "set" function to create a new entity:

 gcloud functions call set --data '{"kind":"Task","key":"sampletask1","value":{"description":"Buy milk"}}'

or

 curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1","value":{"description":"Buy milk"}}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/set"

Replace [YOUR_REGION] with the region where your function is deployed.
Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.

Call the "get" function to read the newly created entity:

 gcloud functions call get --data '{"kind":"Task","key":"sampletask1"}'

or

 curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1"}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/get"

Replace [YOUR_REGION] with the region where your function is deployed.
Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.

Call the "del" function to delete the entity:

 gcloud alpha functions call del --data '{"kind":"Task","key":"sampletask1"}'

or

 curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1"}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/del"

Replace [YOUR_REGION] with the region where your function is deployed.
Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.

Call the "get" function again to verify it was deleted:

 gcloud functions call get --data '{"kind":"Task","key":"sampletask1"}'

or

 curl -H "Content-Type: application/json" -X POST -d '{"kind":"Task","key":"sampletask1"}' "https://[YOUR_REGION]-[YOUR_PROJECT_ID].cloudfunctions.net/get"

Replace [YOUR_REGION] with the region where your function is deployed.
Replace [YOUR_PROJECT_ID] with your Google Cloud Platform project ID.
