I am trying to find a solution (if is possible) to create a python script that pushes a configuration text file (batch of commands ~ 1000s of lines) over ssh.
So far, I have a solution to push few commands, but it doesn't apply when there are 1000s of lines.
Have you heard about Ansible? It does the job you want to do, and it's written mostly in python.
App deployment, configuration management, and orchestration — all from one system. Ansible is simple, agentless automation that anyone can use.
Long story short you writte playboks (.yaml templates). Simply put, playbooks are the basis for a really simple configuration management and multi-machine deployment system, unlike any that already exist, and one that is very well suited to deploying complex applications.
Example playbook:
---
- hosts: webservers
vars:
http_port: 80
max_clients: 200
remote_user: root
tasks:
- name: ensure apache is at the latest version
yum:
name: httpd
state: latest
- name: write the apache config file
template:
src: /srv/httpd.j2
dest: /etc/httpd.conf
notify:
- restart apache
- name: ensure apache is running
service:
name: httpd
state: started
handlers:
- name: restart apache
service:
name: httpd
state: restarted
When you will create playbook that suits your needs just run it against your machine or list of them. There is a huge list of modules available to ansible ready to use. You can also write your own plugins.
