Task logs don't come out if there's only one task

[MasslessParticle]

• Push a logspinner to cf-for-k8s
• run a cf task against the logspinner: cf run-task test "echo "LISTING" && pwd; done" --name TASK_NAME
• No logs come out from cf logs
• run many tasks: for i in $(seq 100); do cf run-task test "echo "LISTING" && pwd; done" --name TASK_NAME$i; done
• logs come out!

This might be because the task is super short lived. How long does it take for fluent tail to recognize new containers?

After five minutes, I don't see messages for runs 13, 16, 17, or 19

Let's try a command that should succeed: In terminal 1:

for x in {10..20} ; do echo $x; cf run-task node-app1 -c "echo test $x"; done

In terminal 2:

Looking at this issue, it looks like the jobs in the namespace for workloads get deleted by eirini(or something) pretty promptly after being completed. This causes the logs for the job to be deleted as well D:
