Ansible, copy script, then execute in remote machine - bash

Question

I want to copy a script to a remote server and then execute it. I can copy it to the directory /home/user/scripts, but when I run ansible script, it returns Could not find or access '/home/user/scripts/servicios.sh'
The full error output is:
fatal: [192.168.1.142]: FAILED! => {"changed": false, "msg": "Could not find or access '/home/user/scripts/servicios.sh'"}
Here is the ansible playbook
- name: correr script
hosts: all
tasks:
- name: crear carpeta de scripts
file:
path: /home/user/scripts
state: directory
- name: copiar el script
copy:
src: /home/local/servicios.sh
dest: /home/user/scripts/servicios.sh
- name: ejecutar script como sudo
become: yes
script: /home/user/scripts/servicios.sh

You don’t need to create a directory and copy the script to target (remote node), the script module does that for you. It takes the script name followed by a list of space-delimited arguments. The local script at path will be transferred to the remote node and then executed. The script will be processed through the shell environment on the remote node. You were getting the error because script module expects the path /home/user/scripts/servicios.sh on your Ansible controller (the node where you are running the playbook from). To make it work you can specify correct path (/home/local/servicios.sh) in script task instead of /home/user/scripts/servicios.sh which is the path on the remote node. So you can change the playbook like this: You can also register the result of that command as a variable if you would like to see that.
---
- name: correr script
hosts: all
become: yes
tasks:
- name: ejecutar script como sudo
script: /home/local/servicios.sh
register: console
- debug: msg="{{ console.stdout }}"
- debug: msg="{{ console.stderr }}"
What if don’t want to go for script module and you are interested in creating a directory and copy the script to target (remote node) explicitly, and run it? No worries, you can still use the command module like this:
---
- name: correr script
hosts: all
become: yes
tasks:
- name: crear carpeta de scripts
file:
path: /home/user/scripts
state: directory
- name: copiar el script
copy:
src: /home/local/servicios.sh
dest: /home/user/scripts/servicios.sh
- name: ejecutar script como sudo
command: bash /home/user/scripts/servicios.sh
register: console
- debug: msg="{{ console.stdout }}"
- debug: msg="{{ console.stderr }}"
But I strongly recommend to go for script module.

Answer 2

The script tag itself transfers the script from the local machine to remote machine and executes it there.
So, the path specified in the script module is of the local machine and not the remote machine i.e., /home/local/servicios.sh instead of /home/user/scripts/servicios.sh
As you have specified the path which is supposed to be on the remote machine, ansible is unable to find that script on local machine at the given path which results in the given error.
Hence, update the path in the task to local path as shown below,
- name: ejecutar script como sudo
become: yes
script: /home/local/servicios.sh
So scripts cant be executed inside the remote server and should be
executed via local machine to the remote?
#thrash3d No, it is not like that. When you use script tag the script is transferred to the remote machine and then it is executed there. If there is a script which you don't want to put on your remote machine and just want to execute it then you can use script tag.
If you want that script on your remote machine then you can first copy your script on remote machine and then execute it there.
Both ways are correct and it is up to you which case suits you better.
