Description

Hi,

My name is José Andreis and I am part of a team that is applying for a call to develop agriculture related applications using the FIWARE platform. We have faced some small problems while trying to configure a cloud server in the FIWARE platform and I would like to know if you could help us with the following questions:

1 - In the Cloud section of FIWARE Lab. I was able to create a keypair, start an instance (Ubuntu server v14), add security group rules to TCP port 22 and allocating a floating IP. But I was never able to associate this IP to the instance so I could connect to the server via ssh using the PEM file generated. I tried creating the instance in several different regions and the problem happened with all. The error below is presented:

{"badRequest": {"message": "Error. Unable to associate floating ip", "code": 400}}

2 - I believe that if I am able to associate the IP to the instance (issue above). I will be able to connect to the server via SSH with no more problems. My second question is if I will be able to access the server files using an FTP/SSH client like CyberDuck or FileZilla to upload or edit files/scripts in the server? Generally I would need an username and password for these clients, so I wonder if there's a place in the FIWARE lab were we can create these credentials?

3 - Is php already installed in the Ubuntu server v14 instance?

4 - With the ubuntu instance. Will we be able to create a blueprint template for Mysql?

5 - Is there an option for phpmyadmin interface for database (MySql) administration? If not, what is the interface for the database administration?

6 - I assume that it will not be a problem. But just to clarify. Will the CRONTAB program be accessible via terminal for the ubuntu template?

7 - When creating an instance. I noticed that we never have Disk space available (NaN GB available). Is there an option where we can allocate disk space for our account?

Thank you very much for your attention.

José

Dear José,

My answers to your questions:
1. This is not a normal behaviour. Could you please send me which region
you use? We can move forward only after that.
2. The images used in FIWARE can be accessed via ssh with your private
key assigned to the vm. However, after that you have root access within
the vm, so you can configure username, password authentication as well.
3. I assume that in the base images it is not the case. They only
provide a base system where you can freely decide what to install.
However, to deploy the necessary software stack the blueprint templates
can be used. To do so, first you have to create a blueprint template by
choosing the region, base os, and the softwares to be installed. After
that you can deploy it, resulting in a new instance with all the
required softwares. Note that this instantiation generally takes much
more time than a simple image deployment.
4. See 3.
5. If apache, php and mysql are also installed, I expect that the answer
is yes. If not, you can install it manually within the vm, using
aptitude or apt-get in ubuntu.
6. Free space is assigned to each vm, but it is not shown in the portal.
However, if the space is not enough, you can create additional volumes
in the portal, an assign them to the vm instance. After that a new disk
appears in the vm (e.g. /dev/vdb), that can be formatted and then
mounted similarly to a real physical disk.

I also advise you to check the videos on instances and blueprints at
http://help.lab.fiware.org/
And the edu pages on Cloud hosting:
http://edu.fi-ware.org/course/category.php?id=4
Blueprint templetes are introduced at
http://edu.fi-ware.org/course/view.php?id=48

I hope this helps you.
Best regards,
Sandor

Dear José,

I have just checked and in Budapest region operated by me and my
colleagues, all the functionalities mentioned below are working
properly. In our region, you should use publicInternal network during VM
creation. After that you can assign a floating IP from the publicRange
to this interface. (similarly floating IP from mdvpnRange can only be
assigned to nic from mdvpnInternal. Note that we will change to a newer
version of openstack soon, where it will be more easier, but now this is
the case.)

However, I forward your issue to the support team of Berlin node so that
they could investigate the problem with their site.
For that I would kindly ask you to send me (cc-d to the list), the
project name (username) used in the cloud portal, and the instance id of
the vm, where the problem was experienced.

Thanks in advance!

Best regards,
Sandor

Thanks Sándor,

I could associate the IP using the Budapest region following your instructions.

I just could not connect to it via ssh. See below:

ssh -i EUI_Budapest.pem root@148.6.80.120

The authenticity of host '148.6.80.120 (148.6.80.120)' can't be established.

RSA key fingerprint is 3f:8d:.......

To connect to the vm we should use the floating IP right? In this case 148.6.80.120

I added a security group rule to TCP port 22 to 22 (Please, see image attached). Am I missing something?

Here is my project name, username and instance ID for Berlin region:

EUIrrigationProject<https://account.lab.fiware.org/applications/euirrigationproject>

Hi José,

We have just checked that you are using a standard ubuntu image, not a
FIWARE-BASE-IMAGE. In this case, you should use the username ubuntu,
with your key. The ubuntu user has sudo rights, so after that you can do
anything you want...

Sorry for that I forgot to mention it.

Best,
Sandor

Hi Sándor,

I stil was not able to connect via ssh, the same error appeared:

Joses-MacBook-Air-4:EUIrrigation ike$ ssh -i EUI_Budapest.pem ubuntu@148.6.80.120

The authenticity of host '148.6.80.120 (148.6.80.120)' can't be established.

RSA key fingerprint is 3f:8d:48:da:c1:c3:99:f5:eb:6d:47:17:93:a8:a0:e3.

Are you sure you want to continue connecting (yes/no)? no

Host key verification failed.

The finger print of my keypair starts with 9e:78:69...

Would you know what could be the problem?

Thanks,

José

Hi,

Please answer yes to the question below. This is the key of the server
side not the one belongs to you.
Please let me know if it helped.
