SE4 Virtualisation TP Wasilewski

Déroulé du TP

Target: discover technologies and use a web server

1. Create VM

1. Create a virtual machine on Proxmox (server is accessible through: this link) by cloning the template. The virtual machine must be named team-XX with XX being your team number assigned at the beginning of the tutorial.
2. Manual configure virtual machine's network to be persistent. Your VM's IP must be 10.99.XX.1/16 with the gateway being 10.99.99.254.
3. Update /etc/hostnameto reflect the VM's name to the hostname
4. Update /etc/hosts with the two previous updates
5. Ensure it can ping google.
6. Reboot the VM and validate it.

2. First web server

1. Install nginx. (Hint: if it fails, do not forget to configure your VM's DNS).
2. Setup a custom/cool static page.

3. First load balancer

1. Install HAProxy 2.8 (Hint: Search "debian haproxy" on your favorite search engine)
2. Redirect port 8888 to the previously installed nginx.

4. Docker time

1. Install docker.
2. Pull nginx image.
3. Copy your custom static page into the container.
4. Reconfigure HAProxy to use port 8889 onto the container.

Target: discover technologies and use a web server

5. Docker image creation with static page / publish on registry

6. Install nomad single instance

7. Create nomad job definition to run previous container with Nomad

8. Increase job definition count to run 3 container / configure HAProxy with auto discovery

9. Add route on Zabeth to view the page

Target: setup a distributed service + deploy from CI

10. Reconfigure nomad to use the common consul and common nomad server

11. Create git repo on Gitlab / Store dockerfile + static page

12. Update job definition in repo / setup CI / deploy new configuration to global nomad

13. Update global haproxy configuration to redirect to the the newly deployed web service

Target: build and deploy more complex services

14. Create new repo as the web repo to build and push a dockerized DHCP server

15. Create a new repo as the web repo to build and push a dockerized TFTP server with ipxe

16. Create a new repo to build and push on S3 a debootstrap image of latest debian version

Target: boot an OS from the network

17. Update web server to host an ipxe configuration file boot this new OS

18. Mount `/home/xxx` as rbd volume from Ceph

Now the new OS boots and use remote storage for users.

Extra parts for experimented SE4

Target: build a custom OS

19. Build a kernel (Bonus: less than 50 Mo + boot time < 2s)

20. Build an init that displays your team ID on the terminal (Bonus: pimped init banner)

21. Build an init that starts network interfaces

Target: create a logging service

22. Create a script / service that request user credentials, checks its validity against /etc/passwd, then mount dynamically user's home from rbd

23. Improve script and update initrd to have a window manager starting after logging
