How to cancel all pulp tasks on a Capsule or Satellite?

Environment

Red Hat Satellite or Capsule 6.9 or older

Issue

Invoked hundreds of pulp tasks on a Satellite or Capsule that we know they are redundant, is there an easy way to cancel all of them?

Resolution

This solution is applicable to 6.9 or older versions. For Satellite 6.10 or newer, please follow this solution.

• First, cancel the pulp tasks themselves:

     pulpAdminPassword=$(grep ^default_password /etc/pulp/server.conf | cut -d' ' -f2)
     
      mongo pulp_database --eval "DBQuery.shellBatchSize = 1000000000; db.task_status.find({'state': {\$nin: [ 'finished', 'error', 'canceled' ]}}, {'task_id': 1, 'state': 1, '_id': 0})" | grep task_id | cut -d\" -f4 > tasks_to_delete.txt
     
     for taskid in $(cat tasks_to_delete.txt); do
    curl -ks -u admin:$pulpAdminPassword -X DELETE https://$(hostname -f)/pulp/api/v2/tasks/${taskid}/
    echo
     done
  
     rm -f tasks_to_delete.txt
  

• Afterwards, optionally, remove messages with the tasks requests by removing the queue that keeps them (a service restart will re-create the queue safely):

  for i in pulp_celerybeat pulp_resource_manager pulp_workers; do service $i stop; done
  qpid-config --ssl-certificate=/etc/pki/pulp/qpid/client.crt  -b amqps://localhost:5671 del queue resource_manager --force
  for i in pulp_celerybeat pulp_resource_manager pulp_workers; do service $i start; done
  

• Apart from this, as the tasks were triggered by some Satellite task(s), it is worth canceling\cleaning them as well. It is recommended to follow this solution for the cleanup.
