Personal edition

[sivashankerN]

Create a personal edition. This Personal edition should have open edx platform installed and ported labs onto it.

Tried installing open edx platform in a vagrant box, because of the network issues, i could not install open edx platform in our local bnetwork. Network issues:

• Unstable network proxy
• Very low download speed. More network bandwidth (download speed) is needed for open edx platform installation
  because of the above issues while installing platform, usually i get
• SSLerror
• Connection timed out error
• Fails downloading required packages of platform
• and more

Finally, open edx platform installation on vagrant box is done. This time i used good network bandwidth ( 1 MBPS download speed) and without any network proxy.

Implementation of the design plan https://github.com/openedx-vlead/portable-media/blob/master/src/index.org#design-plan-on-2016-09-19 did not work using VLEAD's bootstrapping process steps. These steps are actually built using physical machine, not Vagrant box.

This design plan can be implemented if we have time since we need to understand about VirtualBox network configuration with Vagrant box creation.

• Implemented Open edX platform in Vagrant box
• Setting up VLEAD's cluster in Vagrant box is little difficult. Because of the above mentioned reasons.

So, came up with the new design plan https://github.com/openedx-vlead/portable-media/blob/master/src/index.org#design-plan-on-2016-09-23.

Implementation of this design plan is in progress.

• Open edX platform is ready in Vagrant box
• Cluster has been setup with the following server nodes
  1. Router
  2. Reverese Proxy
  3. Public DNS
  4. Private DNS
  5. Auto Deployement service
• Hosted some labs in the cluster

[sivashankerN]

• Imported courses (Labs that are hosted in cluster ) into Open edX platform

Needed external DNS server while configuring Wi-Fi router

• Configured DNS service in one of the OpenVZ container outside the cluster.
• Configuration of DNS service is done from config-server Used same public_dns.yml file to configure. This playbook is same as cluster's public-dns.yml file, no changes needed.
• After configuring DNS service from config-server, In case if you are having any container which has public ip (Wi-Fi Router's Ip range), then we have to add that new container ip to this DNS service

[sivashankerN]

• Complete Portable media has been setup ( Cluster , Open edX platform and configured Wi-FI router ).

Setup is done on basic Desktop machine

• RAM : 16 GB
• Processor : Intel i7 @2.4GHz
• After the setup, Done small test case with one user. In the complete setup , hosted 14 labs in cluster and 3 labs/courses imported onto Open edX platform. Then checked load performance of a course on Open edX platform, each page is loading very slowly. Then, stopped all lab containers, and started one lab container, course pages are loading normally. started 2 more lab containers and tested page loading of a course on Open edX platform, this time also pages are loading normally. started 2 more lab containers (total 5 labs containers running in cluster and 2 course imported to platform), this time also same result,

at 7th lab container, Open edX platform is not able to load course pages very quickly.

Assumption: With two users, with 5 labs running in cluster and 2 courses running in Open edX platform It is tough to serve even 5 labs to 2 users with this kind of machine configuration.

So, We need server grade machine to serve all the labs in cluster and all courses in open edx platform

TODOs::

1. Host/Deploy 68 labs in cluster
2. Import 68 labs into Open edX platform
3. Install Nagios and ELK in host machine
4. Build a Dashboard for OpenVZ containers for administration
5. Clone the HDD
6. Test The Cloned HDD as portable
7. Performance test of portable media

[sivashankerN]

Done today

1. Deployed 50 labs in cluster using ADS ( 16-18 labs are remaining)
2. Installed Nagios and configured RAM usage
3. Install OpenVZ web panel for managing containers through web console (Dash Board) Source https://github.com/sibprogrammer/owp

[sivashankerN]

• Deployed all 68 labs in cluster
• Ported 68 labs into open-edx platform
• analytics-api is added in portable-media in one of the container
