Terraform Plan commented in PR

Have you ever wanted to double-check the Terraform plan before approving a PR without digging into the pipeline’s logs? This code snippet uses the AzDO APIs to post the plan as a comment on the PR, making checking it easier.

- script: |
        terraform plan -out tf.tfplan
  displayName: Generate Terraform plan

- script: |
        terraform show -no-color tf.tfplan > $(Agent.TempDirectory)/tf.txt
  displayName: Convert Terraform plan to text

- bash: |
    cd $(Agent.TempDirectory)
    ENCODED_URL=$(echo "$(System.CollectionUri)$(System.TeamProject)/_apis/git/repositories/${{ variables.SourceRepositoryName }}/pullRequests/$(System.PullRequest.PullRequestId)/threads?api-version=7.0" | sed 's/ /%20/g')
    jq --rawfile comment tf.txt '.comments[0].content=$comment' <<< '{"comments": [{"parentCommentId": 0,"content": "","commentType": 1}],"status": 1}' |
    curl --request POST "$ENCODED_URL" \
