[Fiware-lab-help] FIWARE Lab Assistance

[development at wysee.com]

Hello,

I have some doubts about the use of the platform. I've never worked in a
cloud environment so perhaps all of my questios are just silly =(

I've created a Ubuntu 16.04 instance, configured connection, keypairs,
security, etc... I can now ssh to this instance correctly. I've installed
apache and it's visible in the public IP.

Now, some questions:
1) I've seen apache installation owner is root user. I use ubuntu user to
access the instance via ssh... How can I modify /var/www/html files or
apache configuration if I don't have permission to do it?
2) I've created a new 20GB volume and I've attached it to the instance.
I've rebooted the intance but volume is not visible in /dev/vdc. I'm doing
something wrong? I should mount it manually? How can I do this?

​3) We want to use Fiware to host a yii2 project with different subdomains
and usages (a website, an admin panel, a rest api, an angular app,...) Is
the public IP address generated through floating ips a fixed IP? I mean..
can we safely point our domains to this public IP or it will change in the
future?
4) We also need a cloud storage for a lot of images our app needs. I've
created a container to test. I can upload files there, but I don't know how
to obtain a public URL to access uploaded files. Is this possible?

Thanks in advance,

xavi
