Hi,
I have an easy reproducable example for you:
$ cat simple.json
{
"builders": [{
"type": "docker",
"image": "centos:7",
"export_path": "image.tar"
}]
}
The command *packer build demo.json* (as usual).
Now a small and simple Python setup:
1. Install tox with *pip install tox*. If you have Centos you can say:
sudo yum -y install python-setuptools;sudo easy_install pip; sudo pip
install tox
On Debian it's also easy: *sudo apt-get install python pip;sudo pip
install tox*.
2. Now organize two have a setup.py (choose a folder demo or so).
$ cat setup.py
from setuptools import setup
setup(name='demo',
version='1.0',
description='demo',
long_description='demo',
author='Thomas Lehmann',
author_email='[email protected]',
license="MIT",
install_requires=[],
packages=[],
url="https://github.com/Nachtfeuer/pipeline";,
classifiers=[
"Development Status :: 5 - Production/Stable",
"Intended Audience :: Developers",
"License :: OSI Approved :: MIT License",
"Operating System :: Unix"
])
3. Now provide a *tox.ini* file in same folder
$ cat tox.ini
[testenv]
commands = \
packer build {toxinidir}/simple.json
4. Now just say "tox" and press enter:
$ tox
GLOB sdist-make: /tmp/demo/setup.py
python inst-nodeps: /tmp/demo/.tox/dist/demo-1.0.zip
python installed: demo==1.0
python runtests: PYTHONHASHSEED='3442765722'
python runtests: commands[0] | packer build /tmp/demo/simple.json
WARNING:test command found but not installed in testenv
cmd: /usr/local/bin/packer
env: /tmp/demo/.tox/python
Maybe you forgot to specify a dependency? See also the
whitelist_externals envconfig setting.
docker output will be in this color.
