How to send Terraform plan output to a Slack Channel

Hi @barywhyte !

My guess is the output will need to be formatted in some capacity to allow the cURL to accept the values. I actually sort of ran into a similar situation when setting up the following guide:

Leveraging CircleCI API to include build logs in Slack notifications

Leveraging CircleCI API to include build logs in Slack notifications The Slack Orb allows you to send notifications, and customize the message sent. In most cases, this is used to indicate a build status, such as if it failed. While the above is helpful, it still requires you to navigate back to the build to get information about why it failed. Wouldn’t it be nice if you could include the last few lines of the log output with your Slack message? This could help easily identify the issue, such …

It’s using our CircleCI Slack orb, not a cURL, but you’ll see I needed to massage the output a bit to get it into the right format:

      sed -i 's/\r$//g' slack_response.txt
      SLACK_MESSAGE=$(cat slack_response.txt | tail -n 10 | sed '$!s/$/\\n/' | tr -d '\n')

With the above in mind, you’ll likely need to do something similar to the terraform output before you can pass it along. I think it essentially just needs to be formatted into valid JSON for that cURL to accept it.

I hope the above helps and if I can assist with anything else please let me know!
