Description

This microservice collects Junos configuration
It uses Docker and Ansible.
This microservice:

• instanciates a container
• executes the service (collects Junos configuration)
• stops the container
• removes the container

The Docker image is ksator/collect-junos-configuration

Usage

Install Docker

Pull the Docker image

$ docker pull ksator/collect-junos-configuration

Verify

$ docker images ksator/collect-junos-configuration
REPOSITORY                           TAG                 IMAGE ID            CREATED             SIZE

Create the microservice inputs

Create this structure:

• An inputs directory. With these files:
  • An Ansible Inventory file (hosts.ini) with following variables:
    • ansible_host: IP of the device
    • ansible_ssh_user: Username to use for the connection
    • ansible_ssh_pass: Password to use for the connection
  • A YAML file (format_to_use_when_collecting_configuration.yml) to indicate the desired format for the Junos configuration.
    • The default format is text.
    • Supported formats are:
      • text
      • json
      • xml
      • set

$ ls inputs/
format_to_use_when_collecting_configuration.yml  hosts.ini

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 desired format for the Junos configuration (text, json, xml, set)
Example:

$ more inputs/format_to_use_when_collecting_configuration.yml

---
configuration:
  format: text

Run the microservice

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-junos-configuration
