抑制 Ansible 临时警告

Question

I have a python script that takes advantage of an Ansible ad hoc command to get host information quickly. I'd like to suppress the warning when I'm attempting to gather information about a host that is in a different VPC, but shows in the following command used to find all instances:

aws ec2 describe-instances

Below is the python snippet I'm using to make and generate the ansible ad hoc command:

command_string = "ansible -i /repo/ansible/inventory/"+env+"/hosts " + name + " -m shell -a 'df -h'"
result = subprocess.Popen(command_string, shell=True, stdout=subprocess.PIPE).stdout.read()

I understand that in a playbook setting for the shell module:

warn=no

will disable warnings, but I can't seem to figure out how to do so via adhoc, see below test:

[root@box-1b 10.0.5.xxx:~] ansible -i /repo/ansible/inventory/nqa/hosts 10.19.1.17 -m shell -a 'warn=no'
[WARNING]: No hosts matched, nothing to do

[root@box-1b 10.0.5.xxx:~] ansible -i /repo/ansible/inventory/nqa/hosts 10.19.1.17 -m shell -a 'warn=false'
[WARNING]: No hosts matched, nothing to do

The output of my full script looks similar to the following:

i-xxxxxx
    my-super-cool-box
    t2.small    True
    10.0.0.10
    vol-xxxxxxx
    100
    i-xxxxxxx
    /dev/xvdf


 [WARNING]: No hosts matched, nothing to do
 [WARNING]: No hosts matched, nothing to do
 [WARNING]: No hosts matched, nothing to do

The information printed about the specific instance is correct, and all I'm looking for is a way to suppress that warning without changing the global ansible configurations.

Answer 1

This warning has nothing common with command / shell module warnings, which you can control with warn: no .

This warning is printed by adhoc CLI when you provide host pattern that doesn't match any host from your inventory.

In your example host 10.19.1.17 is not defined in /repo/ansible/inventory/nqa/hosts inventory, so Ansible gives you warning that there's nothing to do.

Make sure that either you run Ansible with hosts that do exist in your static inventory file, or setup ec2 dynamic inventory and run Ansible against all EC2 instances or filter by tag, security_group, etc.

Answer 2

This is worked for me ANSIBLE_PYTHON_INTERPRETER=auto_silent

example: ANSIBLE_PYTHON_INTERPRETER=auto_silent ansible -i /repo/ansible/inventory/nqa/hosts 10.19.1.17 -m shell -a "uptime"

Answer 3

像这样将环境变量ANSIBLE_DEPRECATION_WARNINGS设置为false ：

ANSIBLE_DEPRECATION_WARNINGS=false ansible -i /path/to/inventory hosts -a your_command

Answer 4

ANSIBLE_COMMAND_WARNINGS=false ansible ...
ANSIBLE_COMMAND_WARNINGS=no ansible ...
