Description
Hello!
I am a student and currently my group work on some business project. Idea
is that at our web site will be some short videos, and users also could
upload short videos (from file or directly from PC/mobile camera). It will
be perfect if they could join those short videos in one. This is just basic
function we need.
Now we are looking for cloud platform for our start-up. Looks like at
FIWARE it will be possible to do our project, but now I face some problems.
I'm not server guru yet. Looks like I need some special tools on server
side to perform functions I mentioned above. Seems that Kurento could
provide it. But I had some installation problems.
If I just install Ubuntu from the image it is not possible to install
Kurento, when I tried to create Blueprint Instances myself something went
wrong, at different Regions it work a bit different, for example I created
and download keypair, install B.Insance with kurento installed but keypair
didn't work for my servers at Spain2 and Stockholm regions (keypair was
created in same regions) and setup process at those regions different from
Spain reg. In Spain I was able to intall and connect to my server, but it
was just Ubuntu image, so I was unable to install Kurento by myself. Not
there are no free IP for 2 days in Spain reg. Now I found this
https://www.youtube.com/watch?v=RGdDpyZAPus tutorial, but cant create new
B.Instance in Spain(no IPs).
My questions:
1. Do I understood right, that all additional software (kurent, MySQL,
apache etc.) I have to install through Blueprint Instance creation
interface. Or It is possible to install just Ubuntu for example and then
all services I need?
2. Keypairs are the only way to connect to the server?
3. Is it possible to get future technical support from FIWARE-Lab?
BR, Leonid Zadorozhnykh

Dear Leonid,
Have you set the security groups correctly? By default all the TCP and
UDP ports are closed, so you have to add the proper ports to the
security group used by your instance.
Basically, you can deploy a Kurento instance in two ways: 1. by using
blueprint templates (adding kurento to the tier is enough), 2. by
launching the pre-prepared kurento image available in all the regions.
The 2. option is faster and should work in most of the regions, with
blueprint templates we have experienced some issues that are currently
under investigation.
The Spain region is overloaded and they have run out of public IP
addresses. This will be solved soon, but currently you should try
another region. If you experience some problems e.g. you cannot ssh to
the VM or kurento is not available, or provides bad performance, please
send the issue with the name of the used REGION to this mailing list, so
that the operators of the region could solve the problem.
My answers to your further questions:
1. Do I understood right, that all additional software (kurent, MySQL,
apache etc.) I have to install through Blueprint Instance creation
interface. Or It is possible to install just Ubuntu for example and then
all services I need?
In blueprint templates you can put together a software stack you need
for your app. If you choose kurento, all the dependencies will be
installed automatically. An empty blueprint contains the base OS
basically. After deployment, you cannot modify the instance. (you can of
course remove it and redeploy the modified blueprint...)
2. Keypairs are the only way to connect to the server?
Basically, yes, they are. However, after loging in to the server, you
will have root access, so you can reconfigure the os as you need.
Important, that each region manages the keypairs separately... To access
the vm via ssh, you should add port 22 to the security group assigned to
your vm.
3. Is it possible to get future technical support from FIWARE-Lab?
Yes, you can write to this mailing list or to directly the GE owners
available in the FIWARE catalogue.
Please let me know if the problem is still there and you cannot access
your instance in Spain2 and Stockholm.
Best,
Sandor
