Wrote technical documentation
Worked on migrating DHCP server
Found out about powershell one-liner
Used PowerShell
+ 3
Got the task of migrating the DHCP from one DC to another (different domains) and started by doing it manually, which helped me get a grip on things at first, but was rather tedious. As it turns out there is a god damn Powershell one-liner for that. LOL 

God damn: 
Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml"
Import-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exports\dhcpexport.xml" -BackupPath "C:\dhcpbackup\"
Happy I found it though, will probably come in handy in the future! :)

Am also using diagrams.net (draw.io) for documentation and it looks LIT! 

TBH the most creativity I get as  Sysadmin / IT Support is creating the documentation on things with funky color ways...or by customizing my terminal anyway :D

Don't get me wrong, I get plenty amounts of freedom regarding how to do certain technical tasks, but I really am a visual person/learner and quite miss designing things and playing around with color.  

That's it for now, Cheers! :)

Finished an apprenticeship
Took final exam
Used Docker
Wrote technical documentation
Presented final project
Used Terraform
Talked about Terraform
Talked about linux
Made a presentation using prezi
Used Bash
Deployed VM and Docker container using terraform
+ 9
Finally finished my apprentice ship as an IT apprentice with a practical finishing grade of 93/100 and overall finishing grade of 84/100.
I do suck at written tests tbh and was super nervous during my practical exam, but it went way better than expected! :)

As a final project for my apprentice ship I created and provisioned a VMware virtual machine running Ubuntu and hosting a Docker container running Grav CMS.
I had 32 hours for the whole project from start to finish, including planning and writing the technical documentation for it. (curse you Microsoft Word!) 
Having had almost no experience or business using Docker or Terraform was a terrifying, but also great learning experience.
I handed in my documentation at around 23:58 on the last day and hoooly moly did it feel good having this thing finished at last!

Got 95/100 for the project and couldn't be happier!

While stressfull, it still was a great day all in all! :)
