Post AWS SQS Messages to Slack using Serverless Lambdas
This program requires the Pulumi CLI. If you don’t have it installed already,
get it here or simply run
curl -fsSL https://get.pulumi.com | sh.
After that, you’ll need to configure your AWS credentials so that Pulumi can deploy into your account. If your AWS CLI is already configured, everything should just work.
Since this example uses Slack, you’ll also need an access token.
Running the Program
After installing the CLI and cloning the repo,
cd into the directory, and run these commands:
Install NPM modules using
yarn installif you prefer Yarn).
Create a new stack:
$ pulumi stack init sqs-slack-dev
Configure the required variables:
# Set the AWS region to deploy into: $ pulumi config set aws:region us-west-2 # Configure the Slack channel and access token to use: $ pulumi config set slackChannel "#general" $ pulumi config set slackToken xoxb-123456789012-Xw937qtWSXJss1lFaKeqFAKE --secret
Deploy your program to AWS using the
$ pulumi up
This command will show you the changes before it makes them. As soon as you select
yes, it will begin provisioning resources, uploading your lambda, etc. After it completes, your program is live!
To test this out, push a message into your SQS queue using the AWS CLI:
$ aws sqs send-message --queue-url $(pulumi stack output queueURL) --message-body "Pulumi+AWS rocks :boom:"
If you’ve done everything right, you’ll see a message posted to your Slack channel!
Notice we’ve used the
pulumi stack outputcommand to read the SQS queue URL that was provisioned.
pulumi logs --followcommand to follow the logs. After a short while, you should see
console.logoutput that your message was posted to Slack.
$ pulumi logs --follow 2018-07-05T16:46:03.708-07:00[mySlackPoster-queue-subscripti] 2018-07-05T23:46:03.708Z 68b50931-a005-5e85-b5c4-5a890fee5519 Posted SQS message 3caa4069-f549-44d7-8534-6d61840d3420 to Slack channel #general
If you’d like to make some edits, try changing the
index.jsfile, and then just run
pulumi upagain. Pulumi will detect the minimal set of edits needed to deploy your code.
After you’re done playing around, you can destroy your program and stack by simply running two commands:
$ pulumi destroy --yes $ pulumi stack rm --yes
