Now a month has passed since my last post and Ubuntu 18.04 is almost officially released. It’ll be out on April 26th, 2018. I went ahead and and started building a NetBoot ISO. I found a GitHub repository that contained what I needed. The script simply pulls the NetBoot ISO from a Ubuntu mirror of my choice, extracts it, injects my SSH keys, scripts, preseed file, and whatever else I decide to add. Once the build is prepped, it packs everything up into a nice little 58MB ISO file. From there, I boot the ISO which then promptly runs thru the preseed file and automatically does everything I configured it to do. Once installed and rebooted, I then log in as root with my SSH key assigned to putty or any SSH client, answer a couple questions from a script I put together from the original repository, it does some updating and reboots again. The end result is a system ready to do some whatever with no visible traces that such an install took place. 🙂
The only thing I have to do is answer two questions after it’s first reboot for the host name and domain name then re-login after the 2nd reboot as my chosen user name configured at ISO build time.
Now my ISOs and preseed files utilize a local APT Proxy on my network with the domain name “fileserver.sanlan” using the APT Cacher package. You can either set one up or rebuild the iso.
The other repository I linked in my other post about Server Automation for Linux produced full sized 839MB ISO. This one does everything I need it to do except it requires the Internet to work or mainly, a connection to the APT Proxy I have configured on my local network with all the files preloaded.
Some fine tuning might be needed once Ubuntu 18.04 is officially released but as of today, it’s functional. The only scripts I modified from the original repository was
preseed.cfg, and added
init-host.sh. I deleted the files for 17.10 since I didn’t need or want them. I may carry my changes for 18.04 over to 16.04 for the heck of it.
- Original Repo on GitHub I “stole” most of the code for. 😅
- The other repo I copied some code from🙂 (hint: the start.sh from my forked repo file)
You can’t say they didn’t get credit. 😛 They made the code, I simply modified it for myself. 😊
Enjoy my fellow nerds! 🖖
