Hi Ralf
I had the exact same problem as you and I found that the script fails because
there is no TTY in the remote session opened using ansible
You could use the script batch mode instead, which doesn’t require TTY (flag -b
in the script)
So your ansible task would become:
- name: Use Karaf Client
shell: "./client -v -l 4 -b <<< ls"
args:
chdir: "{{ karaf_install_symlink }}/bin"
Regards,
François
