- Make sure you've followed the steps in Setting Up to have a ready to go Workbench. In the set up phase, we ran
wsk action listto list all the serverless actions that are under the current account. Because this is a fresh account, no actions are listed. Let's create a new nodejs action by running
new hello. A sidecar containing a nodejs action will pop up to the right. By default, the supplied code is a simple hello world action.
- Click the
Deploybutton in the bar beneath the editor portion to send the code to the Nimbella cloud and notice that the status message above the code is updated and the red asterik indicating unsaved changes is now absent. Click in the shell portion (the left half the screen) and type
wsk action invoke hello. This command runs an action in the cloud and will also retrieve and display the result in the sidecar. We call each run of an action an activation which is associated with a globally unique alphanumeric identifier called an activation ID.
- Next, let's edit the action and run it again with parameters this time. Run
edit helloin the shell to being the code editor back. On line 3, change the string
Hey. On line 4, change
console.log('Output:', greeting). Then redeploy the action by clicking the
Deploybutton. Back in the shell, run
wsk action invoke hello -p name anna. This will run the action while passing with the parameter
namebound to the value
anna. As expected, the output now includes the code change and incoming parameter so it says
Hey anna!. Click the
Logstab at the bottom to see the console output.
- Although the action has been deployed, access is so far guarded by the credentials. We can make this action publicly visible by using the running the command
webbify hello. The action is now accessible via the display URL. Copy this URL into a browser (on another computer if desired) to test it. You can also add the query parameter
?name=peterto the end of the URL.
