Creation Of Virtual environment & Ansible Installation

You can use the editor on GitHub to maintain and preview the content for your website in Markdown files.

Whenever you commit to this repository, GitHub Pages will run Jekyll to rebuild the pages in your site, from the content in your Markdown files.

Install virtual environment on fedora

[rothakur@localhost ~]$ sudo pip install virtualenv

Install python 3.4 , 3.5, 3.6, 3.7, 3.8

[rothakur@localhost ~]$ sudo dnf install python34
[rothakur@localhost ~]$ sudo dnf install python35
[rothakur@localhost ~]$ sudo dnf install python36
[rothakur@localhost ~]$ sudo dnf install python37
[rothakur@localhost ~]$ sudo dnf install python38

Go to the directory

[rothakur@localhost ~]$ cd ios-xrv9k

Install virtual environment wrapper

[rothakur@localhost]$ sudo pip install virtualenvwrapper

Edit content of bash_profile file. (you might not have local)

 [rothakur@localhost]$ vi ~/.bash_profile
              export WORKON_HOME="~/venvs"
              VIRTUALENVWRAPPER_PYTHON='/usr/local/bin/python'
               source /usr/local/bin/virtualenvwrapper.sh

run bash_profile

 [rothakur@localhost]$ source ~/.bash_profile

Make vitual environment for desired python version

 [rothakur@localhost]$ mkvirtualenv -p python2.7 ansible27

Create a personal dev-workspace directory and clone the forked git code

 [rothakur@localhost]$ cd ~
 [rothakur@localhost]$ mkdir dev-workspace
 [rothakur@localhost dev-workspace]$ git clone https://github.com/rthakur2590/ansible.git

Edit postactivate file in virtual environment

 [rothakur@localhost dev-workspace]$ vi ~/venvs/ansible27/bin/postactivate
                       cur_dir=`pwd`
                       cd ~/dev-workspace/ansible
                       pip install -r requirements.txt
                       source hacking/env-setup
                       cd $cur_dir
                       clear
                       out="$(ansible --version)"
                       echo $out

Add upstreams

 [rothakur@localhost dev-workspace]$ cd ~/dev-workspace/ansible/
 [rothakur@localhost dev-workspace ansible]$ git remote add upstream https://github.com/ansible/ansible
 [rothakur@localhost dev-workspace ansible]$ git remote -v
 origin	git@github.com:rohitthakur2590/ansible.git (fetch)
 origin	git@github.com:rohitthakur2590/ansible.git (push)
 upstream	https://github.com/ansible/ansible (fetch)
 upstream	https://github.com/ansible/ansible (push)

Checkout upstream branches in gitcode directory

 [rothakur@localhost dev-workspace ansible]$ git fetch upstream
 [rothakur@localhost dev-workspace ansible]$ git rebase upstream/devel
 [rothakur@localhost dev-workspace ansible]$ git checkout -b stable-2.8 upstream/stable-2.8
 [rothakur@localhost dev-workspace ansible]$ git checkout -b stable-2.7 upstream/stable-2.7  
 [rothakur@localhost dev-workspace ansible]$ git checkout -b stable-2.6 upstream/stable-2.6

Set virtual environment with command

 [rothakur@localhost dev-workspace ansible]$  workon ansible27

deactivate virtual environment with command

 [rothakur@localhost dev-workspace ansible]$  deactivate

Note

 Just like we setup environment for python27 we could follow similar steps for other python versions.
