Installing a self-signed certificate on ubports

For my intranet-only nextcloud installation, I have generated a self-signed certificate:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nginx/ssl/nextcloud.key -out /etc/nginx/ssl/nextcloud.crt

I'm running ubports 16.04 stable on a nexus 5.

Two ways to do it, but only worked for me so I'll put it first and the second for reference:

$ openssl pkcs12 -export -in hostname.crt -inkey hsotname.key -out hostname.p12
$ openssl pkcs12 -in hostname.p12 -nodes -out hostname.pem

Other options for this method in comments below:

# Note, the -certfile root.crt appends all CA certs to the export, I've never needed these so it's optional for my personal steps
$ openssl pkcs12 -export -in hostname.crt -inkey hsotname.key -certfile root.crt -out hostname.p12

Note, I've always had my hostname.crt as part of my .pem, so I keep my certs but apparently you may not have to, hence the nocerts flag being an extra option in this sample

#Scaling
#- Scale can be used as is which will set the height to 560 but keep aspect ratio for width.
#- Other options include setting both with & height
#- Watch out for sizing errors when not divisible by 2

if [[ ! "$1" || ! "$2" || ! "$3" ]] || [[ "$1" = '--help' ]]; then
	if [[ "$1" = '--help' ]]; then
		echo " "

Background

I'm currently working on frontend stuff for a JEE application.

Some aspects of my usual frontend workflow seemed difficult to achieve in the first place, so I took some time to find out how to get back to my zero-turnaround workflow, even with a foreign setup that seemed to be difficult for that matter.

There seems to be a lack of documentation or written down experience, so I thought, I could at least publish my personal experience / setup. Comments and complement are very welcome.

I noticed that some frontend developers have problems setting up the java environment, so there's a section for this as well.
