Install Python Modules offline
Installing a python module or package (any applications) is very easy if you have internet connection and access to public repo or private repo.
Eg:
$ pip install pywinrmBut what if your production server do not have internet access and your repo server do not have this package to be installed ?
Here is the simple scenario; I am automating Window machines using Ansible. For Windows modules to work I need pywinrm module to be installed on the Ansible machine and I do not have internet access on Ansible.
Refer all Ansible Learning Guides here.
If the module or library do not have dependancies, then you simply download the package pypi.org/project/pywinrm and transfer this Ansible machine (or the machine which do not have internet access). But in our case, the pywinrm module have dependancies and we do not know what are the dependancies to be installed.
There is an easy method we can follow in this situation.
Download the package from connected machine
Create a directory as repository to keep the packages and dependancies.
user@node1 $ mkdir pywinrm-localFrom a machine which is connected to internet, download the packages and dependancies using pip download command. (We will download the package and dependancies to a directory to avoid mix-up)
user@node1 $ pip download pywinrm -d pywinrm-local

(scp, sftp, winscp etc)
user@node1 $ scp -rp pywinrm-local user@ansible-controlnode:/home/user/pywinrm-localInstall package on the disconnected machine
Verify the transferred packages and dependancy file; you will see all the .whl files inside.
user@ansible-controlnode $ ls -l pywinrm-local

user@ansible-controlnode $ pip list |grep pywinrm
pywinrm 0.4.2You can use this method for any complex python deployments but just need to make sure all the dependancies are downloaded to the same repo directory.

[…] Note: You need to install the other required Python dependencies (e.g., openshift, PyYAML, etc.) for the modules to work. This topic is not in the scope of this article but you can refer to standard procedures (or read how to Install Python Modules offline). […]
