Description

mssh-copy-id is a tool to simplify the copy of SSH keys to multiple servers.

Installation

CentOS 6

TODO

CentOS 7

TODO

Ubuntu 14.04 (trusty)

How to use

Copy the SSH key to 2 servers:

mssh-copy-id [email protected] [email protected]

You can specify the SSH (public) key to send to the servers.

mssh-copy-id -i /path/to/custom/id_rsa root@server1

You can also use the bash expansion to specify several servers:

mssh-copy-id root@server{1..5}

is equivalent to:

mssh-copy-id root@server1 root@server2 root@server3 root@server4 root@server5

You can also send the password on the STDIN:

cat file_that_contains_password | mssh-copy-id root@server{1..5}

Development guide

Install pyenv

pyenv is a tool that allows you to choose different versions of Python for different projects. It has built-in virtualenv support.

Install pyenv

curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash

To use pyenv, you need to source it first. Go to the project source and source the file pyenv.sh:

source pyenv.sh

Then, type:

pyenv update

In the following, we suppose that pyenv is sourced.

Install Python 2.6.6 and create a virtualenv

Before installing any Python interpreters, install the required dependencies.

• Ubuntu/Debian:

  sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev
  

• Fedora/CentOS/RHEL:

  sudo yum install -y zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel patch
  

Source: https://github.com/yyuu/pyenv/wiki/Common-build-problems

Then install gcc:

sudo yum install -y gcc

• Install Python 2.6.6 (default version of CentOS 6):

  pyenv install 2.6.6
  

• Create a virtualenv for mssh-copy-id using Python 2.6.6:

  pyenv virtualenv 2.6.6 mssh-copy-id
  

How to use the virtualenv

• Activate:

  pyenv activate mssh-copy-id
  

Every time you work on the project, remember to activate your virtualenv first.

• Deactivate:

  pyenv deactivate
  

• Remove:

  pyenv virtualenv-delete mssh-copy-id
  

How to install for development

We need to install Paramiko dependencies:

• For Ubuntu:

  sudo apt-get install build-essential libssl-dev libffi-dev python-dev
  

• For CentOS:

  sudo yum install -y gcc libffi-devel python-devel openssl-devel
  

Go to the project directory, and run:

pip install -e .

To install the dev & test libs as well, you can run: (recommended for development)

pip install -e .[dev,test]

How to run the unit tests

You need to install the libraries for tests (see above).

1. One way is to run:

   python setup.py test
   

2. The other way that allows more control & coverage annotations:

   inv test
   

How to run the functional tests

To run the functional tests, you need to have at least Python 2.7.

Install Python 2.7 interpreter:

pyenv install 2.7.12

Create a virtualenv based on Python 2.7 and activate it:

pyenv virtualenv 2.7.12 mssh-copy-id27
pyenv activate mssh-copy-id27

Install the dependencies in that virtualenv:

pip install -e .[dev,test]

Run the functional tests:

inv func-tests

How to build

How to build a wheel package

The python wheel package is more for development purpose, as it requires lib headers for dependencies and compilation tools to be installed.

Requirements

Install the same dependencies as in How to install for development.

Build the wheel package

Go to the project directory, and run:

inv build_wheel

You will find the Wheel package in the dist directory.

Test the installation of the wheel package

• Create a new virtualenv:

pyenv virtualenv 2.6.6 foo
pyenv activate foo

• Go to the dist directory, and run:

  pip install mssh_copy_id-0.0.1-py2-none-any.whl
  

You should be able to run mssh-copy-id as real production.

How to build an RPM package for CentOS 6 & 7

Requirements

• Docker: I tested with version 1.11.2 but I assume that it will work on older versions.

Build the docker image

Run:

inv build_docker -i centos6
inv build_docker -i centos7

It will build the new docker images:

• mssh-copy-id-build-centos6
• mssh-copy-id-build-centos7

Check it:

docker images

Build the RPM packages

Run:

inv build_rpm -t centos6
inv build_rpm -t centos7

The RPM packages will be in dist/rpmbuild/RPMS/noarch.

How to build a deb package

Requirements

• Docker: I tested with version 1.11.2 but I assume that it will work on older versions.

Build the docker image

Run:

inv build_docker -i ubuntu-trusty

It will build the new docker images:

• mssh-copy-id-build-ubuntu-trusty

Check it:

docker images

Build the deb package

Run:

inv build_deb

The deb package will be in dist/deb.

How to upload to PyPI

Source documentation: https://packaging.python.org/en/latest/distributing/#uploading-your-project-to-pypi

Requirements

• twine: tool to upload to PyPI. It is part of the extra dev dependencies. (pip install -e .[dev,test])

How to upload to PyPI

Create a file ~/.pypirc:

[distutils]
index-servers=
    pypi
    pypitest

[pypi]
repository: https://pypi.python.org/pypi
username: <login>
password: <password>

[pypitest]
repository: https://testpypi.python.org/pypi
username: <login>
password: <password>

Build and upload:

inv clean build_src build_wheel
twine upload dist/*.tar.gz dist/*.whl
