Simple webpage for invitations for Apache OpenWhisk Slack Community

Join our Slack https://csantanapr.github.io/openwhisk-slackinvite

Backend is implemented as a serverless action with api gateway route


Deploy action

Configure the wsk CLI with authentication and host

Create the action using wsk CLI and set default parameters

wsk create slackinvite action.js -p org "myslackteam" -p slacktoken "xop-12345..."

The org is the Slack team name, usually the hostname from your .slack.com. The slacktoken is a token for a user with admin access. You can get one from https://api.slack.com/docs/oauth-test-tokens Recommend creating a bot user with admin to use for invites.

Verify the action by invoking with the wsk CLI

wsk action invoke slackinvite -p email "user@example.com"

The action should do a http call to the slack API using the team host and token, then Slack will send the invite to the email provided.

Expose action

Create a public url to invoke the action using wsk CLI

wsk api-experimental create /openwhisk-team /slackinvite GET slackinvite

The command will print the new url created

ok: created api /slackinvite GET for action slackinvite

Verify the exposed url by invoking using the curl CLI or a web browser

curl -X GET https://21ef035.api-gw.mybluemix.net/openwhisk-team/slackinvite?email=user@example.com

Update index.html

Edit the line var actionUrl = "https://..."; and replace the value with your new url that expose your new action.

Deploy to github-pages

Create a new github repo, then go to settings, and set master branch as github page. Push the modified index.html to the new repo, then your webpage would be accesible from https://$username.github.io/$reponame
