ami-val

Introduction

ami-val is a lightweight, fast tests collection for AMIs.

Installation

Install from pip

# pip3 install ami-val

Install from source code

# git clone https://github.com/liangxiao1/ami-val.git
# cd ami-val
# python3 setup.py install

Build wheel from source code and install it

# python3 setup.py sdist bdist_wheel
# pip install -U dist/ami_val-0.0.1-py3-none-any.whl

Public new wheels on pypi (maintainer use only)

# python3 -m twine upload dist/*

Run test

We shared the pre configured aws credentials in "~/.aws/", please specify profile name as below format

# cat ~/.aws/credentials
# aws for default aws regions access
[aws]
aws_access_key_id = xxxxxxx
aws_secret_access_key = xxxxxxxxx
# aws for default china regions access
[aws-china]
aws_access_key_id = xxxxxxx
aws_secret_access_key = xxxxxxxxx
# aws for default us-gov regions access
[aws-us-gov]
aws_access_key_id = xxxxxxx
aws_secret_access_key = xxxxxxxxx

The config file

You can change the default setting in "cfg/ami-val.yaml" locates in the same installed dir.

Below option is must required for ssh login:

# remote_user: user and keyfile to login instance
ssh_user: ec2-user
ssh_keyfile: '/home/virtqe_s1.pem'
# if pair_name keypair not found, will upload ssh_pubfile automatically
# ssh_pubfile is not required if pair_name exists already.
pair_name: virtqe_s1
ssh_pubfile: '/home/virtqe_s1.pub'

Run all ami-val supported cases(the default path is "/usr/local/bin" if not in virtual environment. )

# ami-val -f https://xxxx/pub/task/343012 --paralle
# ami-val -f images.json

The json format should be like this, except required, other are options:

# cat images.json
[
  {
    "ami": "ami-01166axxxxxx", <- required
    "description": "Provided by Red Hat, Inc.",
    "ena_support": true, <- required
    "name": "RHEL-xxxxxx-x86_64-1-Hourly2-GP2", <- required
    "region": "us-east-1", <- required
    "release": {
      "arch": "x86_64", <- required
      "base_product": null, 
      "base_version": null, 
      "date": "20201020", 
      "product": "RHEL", 
      "respin": 1, 
      "type": null, 
      "variant": "BaseOS", 
      "version": "8.x"
    }, 
    "root_device": "/dev/sda1", 
    "sriov_net_support": "simple", 
    "type": "hourly", 
    "virtualization": "hvm", 
    "volume": "gp2"
  }
]

List all supported cases only without run

# ami-val -l

Filter case name with keywords timezone and bash

# ami-val -l -p timezone,bash_history

Filter case name with keywords stage1 and skip timezone check

# ami-val -l -p stage1 -s timezone

Clean the resource created

# ami-val --logdir /tmp/ami_val_344423 --clean

The log file

The console only shows the case test run. The test debug log file are saved in "/tmp/ami_val" following case name by default. If task id can be detected, it will be in "/tmp/ami_val_taskid" by default.

Below is an example:

# ami-val -f https://xxxxxxx/pub/task/343012 --paralle
Run in mode: is_listcase:False pattern:None is_paralle:True
