extras/vpp_config/README.rst - fdio/vpp - Gitiles

 Summary:

 The purpose of the VPP configuration utility is to allow the user to configure
 VPP in a simple and safe manner. The utility takes input from the user and
 then modifies the key configuration files. The user can then examine these files
 to be sure they are correct and then actually apply the configuration. The user
 can also install a released and stable version of VPP. This is currently
 released with release 17.07.

 Use:

 The installation and executing of the VPP configuration utility is simple. First
 install the python pip module. Using pip install, then pip install vpp-config.
 Then simply type Òvpp-configÓ and answer the questions. If you are not sure what
 to answer choose the default. For yes or no questions the capital letter
 designates the default. For example, for a question that shows [Y/n] Y is the
 default. For numbers the default is within the brackets for example for a
 question that shows [1024]. 1024 is the default.

 The flow of the utility is to inspect the system, if VPP is not install it,
 create dry run configurations, inspect the files created during the dry run,
 apply the configuration and then inspect the system again and then repeat.

 Caveats:

 - Only supports Ubuntu, centos7 is coming shortly.
 - When Inspecting the system, you may see a Huge page error, inspect the system a
 few more times, if the error persists it is real.

 For Developers:

 Modifying the code is reasonable simple. The process would be edit and debug the
 code from the root directory. In order to do this, we need a script that will copy
 or data files to the proper place. This is where they end up with pip install. For
 Ubuntu, this is /usr/local/vpp/vpp-config. I have provided a script that will copy
 the relevant files correctly. I have also provided a script that will clean the
 environment so you can start from scratch. These are the steps to run the utility
 in this environment. The scripts are meant to be run from the root directory.

   ./scripts/clean.sh
   ./scripts/cp-data.sh
   ./vpp_config.py

 When the utility is installed with pip the wrapper scripts/vpp-config is written to
 /usr/local/bin. However, the starting point when debugging this script locally is
 ./vpp_config.py. Run the utility by executing ./vpp_config.py from the root directory.

 The start point in the code is in vpp_config.py. However, most of the work is done in
 the files in ./vpplib

 Uploading to PyPi:

 To upload this utility to PpPi simple do the following. Currently, I have my own account
 when we want everyone to contribute we will need to change that.

   sudo ÐH bash
   cd vpp_config
   python setup.py sdist bdist_wheel
   twine upload dist/*

 Example Run:

 # pip install vpp-config
 # vpp-config

 Welcome to the VPP system configuration utility

 These are the files we will modify:
     /etc/vpp/startup.conf
     /etc/sysctl.d/80-vpp.conf
     /etc/default/grub

 Before we change them, we'll create working copies in /usr/local/vpp/vpp-config/dryrun
 Please inspect them carefully before applying the actual configuration (option 3)!

 What would you like to do?

 1) Show basic system information
 2) Dry Run (Will save the configuration files in /usr/local/vpp/vpp-config/dryrun for inspection)
        and user input in /usr/local/vpp/vpp-config/configs/auto-config.yaml
 3) Full configuration (WARNING: This will change the system configuration)
 4) Install/Uninstall VPP.
 5) Dry Run from /usr/local/vpp/vpp-config/auto-config.yaml (will not ask questions).
 6) Install QEMU patch (Needed when running openstack).
 9 or q) Quit

	The purpose of the VPP configuration utility is to allow the user to configure
	VPP in a simple and safe manner. The utility takes input from the user and
	then modifies the key configuration files. The user can then examine these files
	to be sure they are correct and then actually apply the configuration. The user
	can also install a released and stable version of VPP. This is currently
	released with release 17.07.

	Use:

	The installation and executing of the VPP configuration utility is simple. First
	install the python pip module. Using pip install, then pip install vpp-config.
	Then simply type Òvpp-configÓ and answer the questions. If you are not sure what
	to answer choose the default. For yes or no questions the capital letter
	designates the default. For example, for a question that shows [Y/n] Y is the
	default. For numbers the default is within the brackets for example for a
	question that shows [1024]. 1024 is the default.

	The flow of the utility is to inspect the system, if VPP is not install it,
	create dry run configurations, inspect the files created during the dry run,
	apply the configuration and then inspect the system again and then repeat.

	Caveats:

	- Only supports Ubuntu, centos7 is coming shortly.
	- When Inspecting the system, you may see a Huge page error, inspect the system a
	few more times, if the error persists it is real.

	For Developers:

	Modifying the code is reasonable simple. The process would be edit and debug the
	code from the root directory. In order to do this, we need a script that will copy
	or data files to the proper place. This is where they end up with pip install. For
	Ubuntu, this is /usr/local/vpp/vpp-config. I have provided a script that will copy
	the relevant files correctly. I have also provided a script that will clean the
	environment so you can start from scratch. These are the steps to run the utility
	in this environment. The scripts are meant to be run from the root directory.

	./scripts/clean.sh
	./scripts/cp-data.sh
	./vpp_config.py

	When the utility is installed with pip the wrapper scripts/vpp-config is written to
	/usr/local/bin. However, the starting point when debugging this script locally is
	./vpp_config.py. Run the utility by executing ./vpp_config.py from the root directory.

	The start point in the code is in vpp_config.py. However, most of the work is done in
	the files in ./vpplib

	Uploading to PyPi:

	To upload this utility to PpPi simple do the following. Currently, I have my own account
	when we want everyone to contribute we will need to change that.

	sudo ÐH bash
	cd vpp_config
	python setup.py sdist bdist_wheel
	twine upload dist/*

	Example Run:

	# pip install vpp-config
	# vpp-config

	Welcome to the VPP system configuration utility

	These are the files we will modify:
	/etc/vpp/startup.conf
	/etc/sysctl.d/80-vpp.conf
	/etc/default/grub

	Before we change them, we'll create working copies in /usr/local/vpp/vpp-config/dryrun
	Please inspect them carefully before applying the actual configuration (option 3)!
