How do you get the job ID for a pachyderm job dynamically so you can debug it?

The docs suggest you can omit the job id, but it’s a lie!


job_id=($(pachctl list job --no-pager | awk '{ print $1 }' | grep -E '[[:alnum:]]{10,}'))
pachctl inspect job ${job_id}


List the Jobs

pachctl list job will give you something like this.

ID                               PIPELINE              STARTED        DURATION  RESTART PROGRESS      DL UL STATE

If you include paging, you may end up with a fun less error.

less: unrecognized option: X

For details, check out this issue. To skip it, use the --no-pager option.

Grab the First Columns

| awk '{ print $1 }'

This will pipe the job info into awk and grab the first columns.

Grep for a Job ID

| grep -E '[[:alnum:]]{10,}'))

Pipe that into grep and look for any alphanumeric strings at least 10 characters long.

Put it All Together
