Add outputs to show result in pull requests

[robermp]

The stdout of the action is empty, so to see the results in PR some lines are needed:

## Gererate action outputs
echo "::set-output name=err::$res"
command="terrascan scan ${args}"
result=$( $command 2>&1)
result="${result//'%'/'%25'}"
result="${result//$'\n'/'%0A'}"
result="${result//$'\r'/'%0D'}"

echo "::set-output name=result::$result"

With this the in the PR the output of the terrascan can be read like this:

        terrascan_log: "${{ steps.terrascan.outputs.result }}"
        terrascan_err: "${{ steps.terrascan.outputs.err }}"

Using stdout:

Hey @robermp we're trying to do something very similar - where did you insert the above code to get the output you wanted? Do you have a PR against this repo that you could make available?

[robermp]

Hi I insert the code just before these lines inside entrypoint.sh file:

Executing terrascan

echo "Executing terrascan as follows:" echo "terrascan scan ${args}" terrascan scan ${args} res=$?

I cant' do a PR because i'm not contributor

This worked for me. Thank you!

I was also able to use unsplash/comment-on-pr@v1.3.0 to return output to our CI system. Very cool!

Hi @robermp,

A PR would be much appreciated. You should be able to fork the repo and issue a PR from your fork. I'll create the PR if you can't get to it.

@elijah, do you have an example of how you're using unsplash/comment-on-pr@v1.3.0 with the terrascan-action that you could share?

[elijah]

Like this, to push a comment back to the PR:

• name: comment PR for results id: results uses: unsplash/comment-on-pr@v1.3.0 env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} with: msg: "${{ steps.terrascan.outputs.result }}"
