Simple CLI tool to generate configurations for VPCs via CLI.
This is a rather simple script that can be used to create configurations for VPC connections on edge routers. We do this by utilizing a CSV file that contains the information that is needed for this. This will eventually be extended to a bigger application but this was a quick way to get something running that has the beginning steps of building that larger portion of an application.
This is a simple script thats used to create configs for VPC connections on AWS edge routers. The application does this by utilizing a CSV file that contains the information that is needed for this. This should eventually be extended to a bigger application but this was a quick way to get something running that has the beginning steps of building that larger portion of an application.
The script has a few requirements that are listed within the requirements file. You can install these by utilizing pip to install. Once these are installed you are good to begin using the application.
You will need all the information for the VPC outlined in a csv file. Please look at the template_input.csv to see what format the tool is expecting.
You can run python vpcgenerate.py --help for a list of things the tool needs and can do.
(delme) ❯ ./vpcgenerate.py --help vpcgenerate/git/master !+
Usage: vpcgenerate.py [OPTIONS]
Options:
--json TEXT URL of JSON to be used
--csvfile TEXT File that will be used to generate the configurations.
--batch / --no-batch Default is False. If specified this means that all the
configs are placed per router instead of a config for
each VPC.
--help Show this message and exit.
json = The URL of the JSON output to build the configs from.
csvfile = This is the file that contains all the information. This is pretty explanatory.
batch = This may be a little confusing. If you do not place --batch within the cli it will create a configuration for every VPC file. This will be in the format of <router>_<name>_<vlan>.cfg.

│ ├── br02.sea01-coin-aws_0004.cfg
│ └── empty.txt
This may or may not be want you want to do. By specifying --batch within the cli it will only create a config file for each router. All the connections pertaining to that router will be placed in that configuration file.

For the most part --batch should be set or you will have many files.
Using JSON is simple. We are able to pull from JSON format by running the following command:
python vpcgenerate.py --json "https://url" --batch
The above command will pull all the information from the URL and create those templates.
Feel free to spin up the included demo server.
python3 server.py
Once the server is up you can use a tool like postman and perform a PUT to the URL that was started.
Push the following as a test in JSON format:
{"name":"TESTVPC",
"account":1213123,
"ref":"dxlag-strc34",
"vlan":101,
"ipv4_network":"1.1.1.1/24",
"bgp_auth_key":"asdfghhjkljf",
"bgp_community":"65000",
"region_id":"ap-southeast-3"
}
