This is one little part of my working ansible playbook.
I want to send the information which will be gathered to a log file (which the playbook will create)
I have tried so many different way but getting no where.
No error is coming back which can only tell me that the script is working but I guess its going somewhere else other than the destination which I would like it to do
Here is my script
Would be grateful of your thoughts and help
- name: netstat check
shell: netstat -tulnp | awk '{print $4}' | sed -n 's/.*:\([^",]*\)[",]*$/\1/p'
register: netstat
- name: copy output to local file
copy:
content: "{{ netstat.stdout}}"
dest: "/home/user_name/netstat.txt"
Thanks
I executed your playbook in my ansible server(hosts: localhost) and it works fine. A new file is created with the required output.
Incase you want it on the localhost, try giving delegate_to: localhost
- name: copy output to local file
copy:
content: "{{ netstat.stdout}}"
dest: "/home/user_name/netstat.txt"
delegate_to: localhost

I want to extract the path out of the output given by the below command:
Command:
/opt/myapp/dir/bin/client -a 8101 -h localhost -u user -p pass properties-global-export
Output:
client: JAVA_HOME not set; results may vary
Exporting file: org.fusesource.fabric.agent.properties
Exporting file: local.app.node.vendor.service4.properties
Exporting file: local.app.node.data.service3.properties
Exporting file: local.app.node.vendor.service1.properties
Exporting file: local.app.node.vendor.service2.properties
Files dumped into directory: /opt/myapp/install-node/node-2.1.11/data/properties-tmp
and use /opt/myapp/install-node/node-2.1.11/data/properties-tmp path to perform a copy command within my playbook.
- name: Export Properties File
no_log: true
shell: "{{ fuse_esb_client_dir }} -h localhost -a {{ karaf_port }} -u {{ karaf_user }} -p {{ karaf_pass }} properties-global-export | grep -o '\''/[^ ]*'\ "
register: temp
- set_fact:
tempPath: "{{ temp.stdout }}"
- name: All Files Exported To Path
debug: var=temp.stdout
- name: Backup All Property Files to {{ backup_location }}
command: cp -r "{{ tempPath }}" "{{ backup_location }}"
Piped the output to grep grep -o '\''/[^ ]*'\ " The Extra '\' and \ on the start and end is used to escape the regex characters within the playbook. (Remove These if you want to test in your cli)
This Gave Me This Output
/opt/myapp/install-node/node-2.1.11/data/properties-tmp
Dumped that output with set_fact and used it within my playbook.
Hopefully someone finds this usefull. :))) Also for the pros like Jeff :) please let me know if I can improve anything within my playbook.
Only output from the first command is written to the file.
How do I make it write output from all of the commands to the file?
---
- name: run show commands
hosts: nexus1
gather_facts: False
tasks:
- name: run show commands on nexus
nxos_command:
commands:
- show hostname
- show ip route
- show interface
- show ip interface vrf all
- show hsrp
register: output
- name: Copy to server
copy:
content: "{{ output.stdout[0] }}"
dest: "/home/CiscoOutPut/{{ inventory_hostname }}.txt"
You're only asking for output from the first command. output.stdout is a list, one item for the output of each command. When ask for output.stdout[0], you're asking for only the first result.
If you want to write the output of all commands to a file, then something like:
- name: Copy to server
copy:
content: "{{ '\n'.join(output.stdout) }}"
dest: "/home/CiscoOutPut/{{ inventory_hostname }}.txt"
I want to use ansible setup module to retrieve hosts specs and I tried with a bash for loop.
Ansible version: 2.4
My hosts inventory has been defined in a group of machines which I called rhelmachines
I would like to collect the following list of variables called "specs"
declare -a specs=("ansible_all_ipv4_addresses" "ansible_processor" "ansible_processor_cores" "ansible_uptime_seconds")
I am then trying to include the ansible command in a for bash loop:
for i in "${specs[#]}"
do
ansible rhelmachines -m setup -a 'filter='$i'
done
how can I concatenate multiple filters in one connection only ?
Thanks!
With a little sed hackery to convert ansible's output to JSON, you can use jq to extract only the pieces you need:
ansible -m setup localhost | sed -e 's/^[[:alpha:]].*[|].* [>][>] {$/{/' | jq -n '
[inputs |
.ansible_facts as $facts |
$facts.ansible_hostname as $hostname |
{($hostname): {
"ipv4_addresses": $facts.ansible_all_ipv4_addresses,
"processor": $facts.ansible_processor[0],
"cores": $facts.ansible_processor_cores,
"uptime": $facts.ansible_uptime_seconds}}] | add'
...generates output of the form:
{
"my-current-hostname": {
"ipv4_addresses": [
"192.168.119.129"
],
"processor": "Intel(R) Core(TM) i7-6700HQ CPU # 2.60GHz",
"cores": 1,
"uptime": null
}
}
(run with ansible 1.4.5, which doesn't generate uptime).
As one of the possible solution, I implemented an Ansible code exploiting Ansible facts. I implemented it first gathering the ansible facts. Then, I used a local_action and a loop. The loop indices are the several ansible facts. For every fact I am writing out a line of a file. In this way I am getting a file composed by all the ansible facts I declared in the loop for the rhelmachines.
---
- hosts: rhelmachines
gather_facts: True
tasks:
- name: Gather Facts
setup:
gather_subset=all
register: facts
- debug:
msg: "{{ facts.ansible_facts.ansible_all_ipv4_addresses }}"
- name: copy content from facts to output file
local_action:
module: lineinfile
line: "{{ item }}"
path: /tmp/assessments/facts.txt
loop:
- "{{ facts.ansible_facts.ansible_all_ipv4_addresses }}"
- "{{ facts.ansible_facts.ansible_all_ipv6_addresses }}"
I took #Luigi Sambolino answer and make it better. His answer was failing on more than one host in the inventory. He proposed using lineinfile which has one con in this situation - every fact that was the same as other machines were omitted. Other drawback was that results wasn't sorted together, all was mixed.
I needed to take some basic information about systems, like IP, OS version, and so on. Here's my playbook:
- hosts: all
gather_facts: true
ignore_unreachable: true
tasks:
- name: get the facts
setup:
gather_subset=all
register: facts
- name: remove file
local_action:
module: file
path: results
state: absent
- name: save results in file
local_action:
module: shell
cmd: echo "{{ item }}" >> results
with_together:
- "{{ facts.ansible_facts.ansible_default_ipv4.address }}"
- "{{ facts.ansible_facts.ansible_architecture }}"
- "{{ facts.ansible_facts.ansible_distribution }}"
- "{{ facts.ansible_facts.ansible_distribution_version }}"
- "{{ facts.ansible_facts.ansible_hostname }}"
- "{{ facts.ansible_facts.ansible_kernel }}"
Now the results look like this:
...
['10.200.1.21', 'x86_64', 'Ubuntu', '18.04', 'bacula', '4.15.18-7-pve']
['10.200.2.53', 'x86_64', 'Ubuntu', '18.04', 'webserver', '4.15.18-27-pve']
...
Square brackets can be deleted by sed and we have a nice CSV file that can be used with any spreadsheet, for example.
specs=( "ansible_all_ipv4_addresses"
"ansible_processor"
"ansible_processor_cores"
"ansible_uptime_seconds" )
args=( )
for spec in "${specs[#]}"; do args+=( -a "$spec" ); done
ansible rhelmachines -m setup "${args[#]}"
...will result in your final command being equivalent to:
ansible rhelmachines -m setup \
-a ansible_all_ipv4_addresses \
-a ansible_processor \
-a ansible_processor_cores \
-a ansible_uptime_seconds

Running a task on a single host always with Ansible?
(1 answer)
Closed 4 years ago.
I have below ansible playbook in which I want to do few things:
I want to run first task only once in entire time this playbook will be running since I have 100 machines in servers group so "task one" should run only once in the starting.
I want to run task three once as well but at the very end of this playbook when it is working on last machine. I am not sure if this is possible to do as well.
What I need to do is:
Copy clients.tar.gz file from some remote servers to local box (inside /tmp folder) where my ansible is running.
And then unarchive this "clients.tar.gz" file on all the servers specified in "servers" group.
And at the end delete this tar.gz file from /tmp folder.
Below is my ansible script: Is this possible to do by any chance?
---
- name: copy files
hosts: servers
serial: 10
tasks:
- name: copy clients.tar.gz file. Run this task only once during starting
shell: "(scp -o StrictHostKeyChecking=no goldy#machineA:/process/snap/20180418/clients.tar.gz /tmp/) || (scp -o StrictHostKeyChecking=no goldy#machineB:/process/snap/20180418/clients.tar.gz /tmp/) || (scp -o StrictHostKeyChecking=no goldy#machineC:/process/snap/20180418/clients.tar.gz /tmp/)"
- name: copy and untar latest clients.tar.gz file
unarchive: src=/tmp/clients.tar.gz dest=/data/files/
- name: Remove previous tarFile. Run this task only once at the end of this playbook
file: path=/tmp/clients.tar.gz
state=absent
- name: sleep for few seconds
pause: seconds=20
Update
I went through the linked question and it looks like it can be done like this?
---
- name: copy files
hosts: servers
serial: 10
tasks:
- name: copy clients.tar.gz file. Run this task only once during starting
shell: "(scp -o StrictHostKeyChecking=no goldy#machineA:/process/snap/20180418/clients.tar.gz /tmp/) || (scp -o StrictHostKeyChecking=no goldy#machineB:/process/snap/20180418/clients.tar.gz /tmp/) || (scp -o StrictHostKeyChecking=no goldy#machineC:/process/snap/20180418/clients.tar.gz /tmp/)"
delegate_to: "{{ groups['servers'] | first }}"
run_once: true
- name: copy and untar latest clients.tar.gz file
unarchive: src=/tmp/clients.tar.gz dest=/data/files/
- name: Remove previous tarFile. Run this task only once at the end of this playbook
file: path=/tmp/clients.tar.gz
state=absent
delegate_to: "{{ groups['servers'] | last }}"
run_once: true
- name: sleep for few seconds
pause: seconds=20
I am trying to read an Environment variable from Target Linux Host using Ansible playbook. I tried all the below tasks as per the document but there is no result.
- name: Test1
debug: msg="{{ ansible_env.BULK }}"
delegate_to: "{{ target_host }}"
- name: Test2
shell: echo $BULK
delegate_to: "{{ target_host }}"
register: foo
- debug: msg="{{ foo.stdout }}"
- name: Test3
debug: msg="{{ lookup('env','BULK')}} is an environment variable"
delegate_to: "{{ target_host }}"
The Environment variable "BULK" is not set in the local Host where I am executing the playbook, so I assume its returning nothing. Instead of BULK, if I use "HOME" which is always available, it returns the result. If I SSH into the target_host I am able to run echo $BULK without any issue.
How to obtain the Environment variable from the remote host?
If I SSH into the target_host I am able to run echo $BULK without any issue.
Most likely, because BULK is set in one of the rc-files sourced only in an interactive session of the shell on the target machine. And Ansible's gather_facts task runs in a non-interactive one.
How to obtain the Environment variable from the remote host?
Move the line setting the BULK variable to a place where it is sourced regardless of the session type (where exactly, depends on the target OS and shell)
See for example: https://unix.stackexchange.com/a/170499/133107 for hints.
source /etc/profile and then grep the env
my solution is not perfect, but often works. for example i want to check if the remote_host has environment variables for proxy servers, i do the following:
as an adhoc ansible command:
ansible remote_host -b -m shell -a '. /etc/profile && (env | grep -iP "proxy")'
Explanation:
i prefere the shell module, it does what i expect... the same if i do it on a shell
. /etc/profile sources the /etc/profile. And this file sources other files like under /etc/profile.d . So after this i have the fix machine part of the environment.
env | grep -iP "proxy" then filter the expanded environment for my variables i am looking for
Remote environment variables will be automatically gathered by ansible during the "Gathering Facts" task.
You can inspect them like this:
- name: inspect env vars
debug:
var: ansible_facts.env
In your case try this:
- name: Test4
debug: msg="{{ ansible_facts.env.BULK }} is the value of an environment variable"
