Hello all,
I am trying to provision Karaf using Ansible (on localhost). All is good
until I first try to use the bin/client script to interact with the
local Karaf server. For some reason all interactions, no matter what I
try, end with the error "Closed". However, I can run the client script
successfully on the command line. I ran the client with full trace logs
(-v -l 4) with Ansible and on the command line and diffed the output.
Apart from session IDs, timestamps, and encrypted content on the wire
the logs look identical as far as I can see until we reach this line:
[main] DEBUG org.apache.sshd.client.session.ClientSessionImpl -
createExecChannel([ClientSessionImpl[karaf@localhost/127.0.0.1:8101],
ls, 0, null])[null] created id={} - PTY={}
After which the client continues to process the ls​ command if called on
the command line and immediately closes the connection when called via
Ansible:
525 [Thread-2] DEBUG org.apache.sshd.client.channel.ChannelExec -
close(ChannelExec[id=0,

[..]
All output is on level DEBUG or TRACE. No error is reported.
The Ansible task is as simple as they come:
- name: Use Karaf Client
shell: "./client -v -l 4 ls"
args:
chdir: "{{ karaf_install_symlink }}/bin"
The karaf server log shows the connection, and a while later logs an
authentication timeout, presumably because the client left the
conversation dangling.

Where would I have to tweak the setup to make the karaf client work
through Ansible?
Thanks!
