ansible命令/ shell模块似乎没有评估和选择参数

Question

I am running an ansible playbook (ansible V1.9.4) inside of a role which I'm trying to install and running a command with parameters but when I try to execute from from Anisble-playbook on task - name: Run installation of cht agent , it doesn't run properly but in fact hangs during the execution of this task. In contrary, when I ran the command manually on the ec2 host itself, it ran perfectly without any issues. What I observed is there might be parameters not properly passed from ansible-play's task to the host, but I might be wrong on it.

This is my playbook that I'm running,

---
# tasks file for cloudhealth-agent installation
- name: Download the agent
  command: wget https://s3.amazonaws.com/remote-collector/agent/v14/install_cht_perfmon.sh -O /tmp/install_cht_perfmon.sh

- name: Run installation of cht agent
  command: sh /tmp/install_cht_perfmon.sh 14 {{ cht_unique_registration_code }} aws
  args:
    creates: /opt/cht_perfmon
  sudo: yes
  register: install_cmd

- debug: var= {{ install_cmd | to_nice_yaml }}

The output of my playbook execute is at below,

$ ansible-playbook -i inventory/ec2.py cloudhealth-agent.yml -vvv

^CERROR: interrupted

Noticed the last line it shown an empty bunch of quotes, -u root /bin/sh -c '"'"' . This seems to me the command syntax is not passing the parameters properly. Any idea or suggestion on how to resolve or feed the proper command line to execute at remote host?

Answer 1

I got this issue resolved. It wasn't with my ansible syntax on command or shell, but I was passing the wrong API key that it resulted the 'install_cht_perfomsh' not able to process with the wrong key.

~thanks for help

Answer 2

You should use the shell - Execute commands in nodes :

The shell module takes the command name followed by a list of space-delimited arguments. It is almost exactly like the command module but runs the command through a shell (/bin/sh) on the remote node.

- name: Run installation of cht agent
  shell: bash -c "/tmp/install_cht_perfmon.sh 14 {{ cht_unique_registration_code }} aws"
  args:
    creates: /opt/cht_perfmon
  sudo: yes
  register: install_cmd

or:

- name: Run installation of cht agent
  shell: /tmp/install_cht_perfmon.sh 14 {{ cht_unique_registration_code }} aws
  args:
    creates: /opt/cht_perfmon
  sudo: yes
  register: install_cmd
