Force Cancel Multiple Runs together using TFC API

Introduction :-

                              Sometimes, Users have many TFC runs which are stuck due to anonymous reason , in some cases user need to cancel those RUNs to clear up the processing queue so that new runs can take place to process .

Solution :-

                              First, Please gather correct list of run-ids of all pending runs , This can be accomplished using the below mentioned commands, Please make sure below mentioned API cannot be accessed with organization tokens. You must access it with a user token or team token.

curl \
  --header "Authorization: Bearer $TOKEN" \
  --header "Content-Type: application/vnd.api+json" \
  https://app.terraform.io/api/v2/workspaces/<WS-ID>/runs | jq | grep -e '"status": "pending"' -e '"id":' | grep pending -B1 | grep id | awk -F '"' '{print $4}' > list_of_pending_runs.txt

The pending runs should be saved to list_of_pending_runs.txt file in your local directory. Make sure those are the correct run-ids by comparing them to the UI.

Now from command line you can do a loop over the list of runs using the discard runs API call effectively canceling the pending runs in the workspace.

for i in  `list_of_pending_runs.txt` ;
do curl \
  --header "Authorization: Bearer $TOKEN" \
  --header "Content-Type: application/vnd.api+json" \
  --request POST \
  --data @payload.json \
  https://app.terraform.io/api/v2/runs/$i/actions/discard | jq;
done

A sample for the payload.json can be:

{
  "comment": "This run was discarded"
}

Additionally you can check the instructions on how to work with the runs API here.
