Using containers causes the java process to hang after the run completes #209

Closed willr3 closed 3 months ago

willr3 commented 3 months ago

The jar does not exit when a host starts a container on either the LOCAL or a remote connection. The run completes, the json server stops, to pod stops, but the process does not exit.

recreate script

scripts:
  foo:
  - sh: uname -a
  - sh: echo "foo" > foo.txt
  - queue-download: foo.txt
  - sh: ls -al
  - sh: date

hosts:
  target:
    local: true
    platform: docker
    container: quay.io/fedora/fedora

roles:
  run:
    hosts: [target]
    setup-scripts:
    - foo

Attached are stack traces for 2 different scripts (one is the sample above);

test.jstack.txt kb_qdup.jstack.txt

It appears the Json Server and the LocalShell threads have not been closed down
