OS / Environment

QFX5100-VC / Junos 17.4

Summary

When kicking off a NSSU with ansible using verbose mode, none of the NSSU progress is logged

Steps to reproduce

Use NSSU on a virtual chassis setup

- name: Install Junos OS package QFX5K
  ignore_errors: yes
  juniper_junos_software:
    install_timeout: 2700
    version: "17.4R2-S2.3"
    cleanfs: no
    local_package: "/opt/ansible/software/jinstall-host-qfx-5-17.4R2-S2.3-signed.tgz"
    remote_package: "/var/tmp/jinstall-host-qfx-5-17.4R2-S2.3-signed.tgz"
    nssu: yes
    checksum:
    reboot: true
    validate: false
    force_host: yes
    logfile: /opt/ansible/logs/{{ inventory_hostname }}-logs.log
    user: "{{ username }}"
    passwd: "{{ password }}"
  register: sw

- name: Check Status
  debug:
    var: sw

Expected results

Would be nice to see some of the NSSU progress in the logs defined in logfile

Actual results

The logs show the initial software install command, but then nothing else during the whole process

2019-05-14 15:04:55,310 - ncclient.transport.ssh - ERROR - Socket exception: Connection reset by peer (104)

The ERROR there is because the netconf session dies after the master RE flip, I've reported that bug here https://github.com/Juniper/ansible-junos-stdlib/issues/431

@lucasalvatore1, Streaming logs from a running task isn't supported in Ansible currently, there is a proposal for this at https://github.com/ansible/proposals/issues/92. We will have to wait for this to get implemented to proceed further.

Alternatively, juniper_junos_software logs the progress to the logfile mentioned in the task and is updated in realtime, unlike ansible-playbook output. You could tail the log file to know the progress of the install process.

Sample task:

- name: Execute a basic Junos software upgrade with logging.
  juniper_junos_software:
    local_package: "./images/"
    logfile: install.log
    level: DEBUG
