Create this structure:
- An
inputsdirectory. With these files:- An Ansible Inventory file (
hosts.ini) with following variables:ansible_host: IP of the deviceansible_ssh_user: Username to use for the connectionansible_ssh_pass: Password to use for the connection
- A YAML file (
show-commands-to-collect.yml) to indicate the list of Junos show commands you want to collect
- An Ansible Inventory file (
$ ls inputs
hosts.ini show-commands-to-collect.yml
Ansible inventory example:
$ more inputs/hosts.ini
[spines]
demo-qfx10k2-14 ansible_host=172.25.90.67
demo-qfx10k2-15 ansible_host=172.25.90.68
[leaves]
demo-qfx5110-9 ansible_host=172.25.90.63
demo-qfx5110-10 ansible_host=172.25.90.64
[all:vars]
netconf_port=830
ansible_ssh_user=ansible
ansible_ssh_pass=juniper123
Configure the details you want to collect. Example:
$ more inputs/show-commands-to-collect.yml
---
cli:
- "show chassis hardware"
- "show version"
This will instanciate a container, execute the service, stop the container and remove the container.
$ docker run -it --rm -v ${PWD}/inputs:/inputs -v ${PWD}/outputs:/outputs ksator/collect-show-commands
