How to create an instant job?

[talexu]

Expected Behavior

Create a job, the job will run once immediately.

Actual Behavior

Create a disabled job, then invoke API to run the job, which means that I have to invoke two APIs (POST /jobs, POST /jobs/{job_name}) for instant job.

Specifications

• Version: 1.2.0
• Platform: Mac
• Backend store: Redis

@talexu I don't know if dkron will be the best tool for that use case but you can submit a job to be run in the next few seconds:

run_next=`date '+%FT%T:Z' --date='5 seconds'`

curl localhost:8080/v1/jobs -d "{
  "name": "job1",
  "schedule": "@at $run_next",
  "disabled": true,
  "executor": "shell",
  "executor_config": {
    "command": "echo 'Hello from Dkron'"
  }
}"

@Victorcoder Thank you for your reply. What I am going to develop is a cross-region job schedule system. Each job in a job chain may be run in different data center.
Could you please give me some advices about how to design and implement such kind of system (e.g. framework, storage, infrastructure)?

@talexu For an implementation cross-region I would recommend using DynamoDB global table for the backend on AWS and configure 2 dkron clusters in an active-passive fashion, you can work something like that using tags and the proper configuration.
