kandi X-RAY | redis-scheduler Summary
a simple, production-ready chronological scheduler for redis. it allows you to schedule items to be processed at arbitrary points in the future, and easily retrieve only those items that are due to be processed. it does everything you’d expect from a production scheduler: * you can schedule arbitrary items at arbitrary times. * you can iterate over ready items in either blocking or non-blocking mode. * it supports multiple concurrent producers and consumers. * an application exception causes the item to be rescheduled at the original time. * work items lost as part of an application crash or segfault are recoverable. in non-blocking mode, redisscheduler#each

QUESTION
I am exploring this project https://github.com/davidmarquis/redis-scheduler. I have setup on my local and am able to run the integration test cases. Now, I am trying to create an application end point to set some delayed task and start the polling thread. I have been able to get my task stored in a redis zset (via the RedisTaskScheduler->scheduleAt() method) but I am not able to get the polling process started which is supposed to remove the keys from the zset.
Following is what I did -
Following is an entry point I have created -

QUESTION
I have a bunch of pods in kubernetes which are completed (successfully or unsuccessfully) and I'd like to clean up the output of kubectl get pods
. Here's what I see when I run kubectl get pods
:
ANSWER
Answered 2019-Mar-08 at 23:06Here's a one liner which will delete all pods which aren't in the Running
or Pending
state (note that if a pod name has Running
or Pending
in it, it won't get deleted ever with this one liner):
kubectl get pods --no-headers=true |grep -v "Running" | grep -v "Pending" | sed -E 's/([a-z0-9-]+).*/\1/g' | xargs kubectl delete pod
Here's an explanation:
- get all pods without any of the headers
- filter out pods which are
Running
- filter out pods which are
Pending
- pull out the name of the pod using a sed regex
- use
xargs
to delete each of the pods by name
Note, this doesn't account for all pod states. For example, if a pod is in the state ContainerCreating
this one liner will delete that pod too.
