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 directory
configuration_fileswith Junos configuration files- All formats (xml, set, text, json) are supported. The format is determined by the file extension (.conf, .xml, .set, .json)
- A YAML file (
type_to_use_when_loading_configuration.yml) to indicate how do you want to load the configuration (replace, merge, overwrite)
- An Ansible Inventory file (
$ ls inputs
configuration_files hosts.ini type_to_use_when_loading_configuration.yml
Ansible inventory example:
$ more inputs/hosts.ini

}
}
}
}
}
Indicate how do you want to load the configuration
$ more inputs/type_to_use_when_loading_configuration.yml
load_type: "merge"
This will instanciate a container, execute the service, stop the container and remove the container.
