gNXI Test Client

A CLI tool for orchestrating tests against a gNXI target.

How it works

• gnxi_tester communicates with you local docker socket via the Docker SDK.
• It will read ~/.gnxi.yml which defines which service binaries will be put in lightweight containers on the host system as well as a set of commands and desired outputs.
• It will execute the predefined commands for each binary, passing in files and and user input when necessary
• If all tests pass, it will notify the user and exit gracefully.

Web UI

Dependencies

• docker
• docker-compose

Running

We have provided a shell script to both install and run the Web UI and API.

Then run this command:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/google/gnxi/master/gnxi_tester/web.sh)"

It will install gNxI in ./gnxi. You can subsequently launch the API and Web UI by:

cd ./gnxi/gnxi_tester && docker-compose up -d

Development

If you have cloned the repository, in order to run the development environment for both the Web UI and API, you have to run the following command in this directory:

docker-compose up -f docker-compose.dev.yml

CLI

Installing

go get github.com/google/gnxi/gnxi_tester
go install github.com/google/gnxi/gnxi_tester

Running

Tests are provided in ~/.gnxi.yml. By default, the following processes & clients will be run:

• provision
• gnoi_os
• gnoi_cert
• gnoi_reset

For example, the auto generated ~/.gnxi.yml will look like:

docker:
  build: golang:1.14-alpine
  runtime: alpine:latest
order:
- gnoi_os
- gnoi_cert
- gnoi_reset
tests:
  gnoi_cert:
  - args:
      op: get
    doesntwant: ""
    mustfail: false
    name: Get certs
    prompt: []
    wait: 10
    wants: GetCertificates:\n{\w*
    [...]
  gnoi_os:
  - args:
      op: install
      os: '&<os>'
      version: '&<os_version>' # escaped variables the user will be prompted for
    doesntwant: ""
    mustfail: false
    name: Compatible OS with Good Hash Install
    prompt:
    - os_version
    - os
    wait: 0
    wants: ^$
    [...]
  gnoi_reset:
  - args: {}
    doesntwant: ""
    mustfail: false
    name: Resetting a Target Successfully
    prompt: []
    wait: 0
    wants: ^$
  provision:
  - args:
      cert_id: '&<cert_id>'
      op: provision
    doesntwant: ""
    mustfail: false
    name: Provision Bootstrapping Target
    prompt:
    - cert_id
    wait: 0
    wants: Install success

If [test_names] are provided, only those tests are ran.

gnxi_tester run [test_names] \ 
--ca certs/ca.crt \
--ca_key certs/ca.key \
--target_name target.com \
--target_address localhost:9339 \
--files "os:/path/to/image other_file:/path_to_file"

Files required by service

Files to be passed in the --files flag:

gnoi_os

• os: Path to OS file used in install operation.
• new_os: Path to another OS file used in install_another_os operation.
