=== Installing the client ===

If you are on debian/ubuntu, you can install the nova client with `apt-get`:
{{{
$ sudo apt-get install python-novaclient
}}}

!RedHat based distributions also include the package in EPEL repositories. You can install it with `yum`:
{{{
$ yum install python-novaclient
}}}

Alternatively, you can use `pip` to install the python package directly:
{{{
$ pip install python-novaclient
}}}

The [[Cluster/Usage|GRIDUI Cluster (SL6 machines)]] include a ready to use installation for IFCA local users.

=== Getting the credentials ===

The easiest way to obtain your credentials is using the dashboard of !OpenStack:
login into [[http://portal.cloud.ifca.es|Web portal]] and go to your Access & Security area (the link is in the section Projects) and then to the API Access subsection. There you will a button to download the !OpenStack RC File that can be used with the `nova` commands.

Download or copy the configuration file for !OpenStack to your directory.
Source it in order to have the environment ready, providing the corresponding password:
{{{
$ . openrc.sh
Please enter your OpenStack Password:
}}}

Now you should be able to execute the commands to access the CLOUD resources.
 
Try that your environment is correct with the `nova endpoints` command. It should return all the services available in the !OpenStack installation:

== Managing machines ==

The cloud service lets you instantiate virtual machines (VM) on demand. When you request the creation of a new VM, you can select the operating systems and the size (RAM, Disk, CPUs) that will be used to run the machine. In this section we will show how to discover which software and sizes are available and how to start a new virtual machine.

=== Keypairs ===

Before attempting to start a new virtual machine, you should have a keypair that will allow you to login into the machine once it is running. Normally you just need to create one keypair that can be reused for all your virtual machines (although you can create as many SSH credentials as you want).

The `nova keypair-list` command shows your current keypairs. Initially the command should not return anything.

In order to create a new key, use `nova keypair-add` with a name for the key you want to use redirecting the ouput to the file where you want to store that key. For example, for creating a key named `cloudkey` that will be stored in `cloudkey.pem`:

{{{
$ nova keypair-add cloudkey > cloudkey.pem
}}}

Your recently created keypair should now appear in the list of available keypairs:

{{{
$ nova keypair-list
+----------+-------------------------------------------------+
| Name | Fingerprint |
+----------+-------------------------------------------------+
| cloudkey | 37:fd:b6:73:59:78:fd:f2:7f:e7:9c:1b:9a:88:a5:cb |
+----------+-------------------------------------------------+
}}}

Make sure that you keep safe the file `cloudkey.pem`, since it will contain the private key needed to access your cloud machines. Set proper permissions to the key before using it with `chmod 600 cloudkey.pem` (only user can read or write). If you need to delete one of your keypairs, use the `nova keypair-delete` command.

=== Images ===

The service lets you run VMs with different Operating Systems, you can list all the available ones with the `nova image-list` command. The `ID` of the image will be used as arguments for other commands.

Information about some of these images is available at [[Cloud/Images]].

=== Sizes ===

As in the case of the image to use, you can select the size of the VM to start. The list of available sizes (flavors in !OpenStack terminology) can be obtained with `nova flavor-list`:

=== Starting a machine ===

For starting a new VM, you need to specify one image, one size and a name for the new machine. Optionally, you can also spcify a keypair (it is always recommended to do so). The `nova boot` command lets you start the machine. For example, in order to create a VM that:
 * runs IFCA Scientific Linux 5.5 JeOS (ID `18d99a06-c3e5-4157-a0e3-37ec34bdfc24`)
 * of size `m1.tiny`
 * with the key `cloudkey`
 * and named `testVM`
you would need to issue the following command:

{{{
$ nova boot --flavor m1.tiny --image 18d99a06-c3e5-4157-a0e3-37ec34bdfc24 --key_name cloudkey testVM

+--------------------------------------+--------------------------------------+--------+-------------------------------------+
}}}

=== Connecting to the machine ===

Once the machine status is `ACTIVE`, it will be ready for using it. You can connect via ssh with your key. The IP address of the machine is shown in the `nova list` output.

{{{#!wiki caution
'''VMs have private IPs by default'''

Your VMs will be created with a private IP within a VLAN only accessible from your VMs. In order to reach the machine from outside that VLAN, you will need to assign a public IP to the VM. See below in the [[#Networking|Networking]] section on how to do this.
}}}

{{{
$ ssh -i cloudkey.pem root@172.16.2.8
Last login: Mon May 10 16:11:40 2010
[root@testvm ~]#
}}}

=== VM Lifecycle ===

Your VM will be available until you explicitly destroy it. You can pause/reboot/resume/delete the machine with these commands:

|| Action || Command ||
|| Reboot the VM || `nova reboot <id>` ||
|| Pause the VM || `nova pause <id>` ||
|| Suspend the VM || `nova suspend <id>` ||
|| Resume the VM || `nova resume <id>` ||
|| Delete the VM || `nova delete <id>` ||

Deleting the machine will destroy it and the contents of the disk will be lost. Make sure that all your data are stored in a permanent storage before deleting the machine. See the section on volumes for more information.

}}}

== Permanent Storage: Volumes ==

The VMs use a temporary disk that is destroy when the machine is deleted. If you need permanent storage for your data, you can use Volumes. Volumes are raw block devices that can be created dynamically with a desired size. Volumes can be ''attached'' and ''detached'' from a running cloud VM to be used as a data disk (similarly to a usb stick that can be plug and unplugged to a computer).

=== Creating Volumes ===

The `nova volume-create` creates new volumes. You must specify the size (in GB) and optionally a name. In our case we will create a new volume with 5GB called `mydata`

{{{
$ nova volume-create --display-name 'mydata' 5
+---------------------+----------------------------+
| Property | Value |
+---------------------+----------------------------+
| attachments | [] |
| availability_zone | nova |
| created_at | 2012-09-28 15:16:44.590600 |
| display_description | None |
| display_name | mydata |
| id | 14 |
| metadata | {} |
| size | 5 |
| snapshot_id | None |
| status | creating |
| volume_type | None |
+---------------------+----------------------------+
}}}

The `nova volume-list` shows all available volumes:
{{{
$ nova volume-list
+----+-----------+--------------+------+-------------+-------------+
| ID | Status | Display Name | Size | Volume Type | Attached to |
+----+-----------+--------------+------+-------------+-------------+
| 14 | available | mydata | 5 | None | |
+----+-----------+--------------+------+-------------+-------------+
}}}

The volume is now created and can be attached to a VM.

=== Attaching Volumes ===

Attaching is the process of associating a volume with a given instance, so the volume is seen as a new block device in the VM. The command to attach the volume is `nova volume-attach`, and the parameters are:
 * the id of the VM
 * the id of the volume
 * the local block device where the volume will be attached. These devices are in the form `/dev/xvd<DEVICE_LETTER>`, where `<DEVICE_LETTER>` goes from `c` to `z` (`/dev/xvdc`, `/dev/xvdd`, ..., `/dev/xvdz`)

For example:

{{{
$ nova volume-attach 9f870141-638e-4eb9-a2fa-ec770d1edb79 14 /dev/xvdc
+----------+-------+
| Property | Value |
+----------+-------+
| id | 14 |
| volumeId | 14 |
+----------+-------+
}}}

`nova volume-list` should now show that the volume is attached:

{{{
$ nova volume-list
+----+--------+--------------+------+-------------+--------------------------------------+
| ID | Status | Display Name | Size | Volume Type | Attached to |
+----+--------+--------------+------+-------------+--------------------------------------+
| 14 | in-use | mydata | 5 | None | 9f870141-638e-4eb9-a2fa-ec770d1edb79 |
+----+--------+--------------+------+-------------+--------------------------------------+
}}}

Log into your VM and check with `dmesg` that the volume is now attached:
{{{
[root@testvm ~]# fdisk -l | grep Disk
Disk /dev/xvda doesn't contain a valid partition table
Disk /dev/xvdc doesn't contain a valid partition table
Disk /dev/xvda: 3220 MB, 3220176896 bytes
Disk identifier: 0x00000000
Disk /dev/xvdc: 5368 MB, 5368709120 bytes
Disk identifier: 0x00000000
}}}

{{{#!wiki caution
Volumes are created without any kind of filesystem, you will need to create one the first time that you use it. A single ext4 partition should be enough for most use cases. You can create such filesystem with this command from your VM: `mkfs.ext4 /dev/xvdc` (change `/dev/xvdc` if needed)
}}}

Now you can mount your volume (for example in /srv) and start using it:
{{{
[root@testvm ~]# mount -t ext4 -o sync /dev/xvdc /srv
[root@testvm ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda 3.0G 790M 2.1G 28% /
tmpfs 245M 0 245M 0% /dev/shm
/dev/xvdc 5.0G 138M 4.6G 3% /srv
}}}

=== Detaching Volumes ===

Once you are done with the volume, you can umount it at your VM:
{{{
[root@testvm ~]# umount /dev/xvdc
}}}

And detach it from the VM with `nova detach` with the VM and Volume id as arguments:
{{{
$ nova volume-detach 9f870141-638e-4eb9-a2fa-ec770d1edb79 14
}}}

The volume should appear again as available when you list it:
{{{
$ nova volume-list
+----+-----------+--------------+------+-------------+-------------+
| ID | Status | Display Name | Size | Volume Type | Attached to |
+----+-----------+--------------+------+-------------+-------------+
| 14 | available | mydata | 5 | None | |
+----+-----------+--------------+------+-------------+-------------+
}}}

=== Deleting volumes ===

You can reuse as many times as you like your volumes in your VMs, the data stored in them will persist after you have destroy your VMs. If you no longer need one of your volumes, you can do so with the `nova volume-delete` command. Once you delete a volume, you will not be able to access to its data again!.

{{{
$ nova-delete 9
}}}

== Networking ==

All created VMs have a private IP within a VLAN accessible only from the VMs. If you need access to a machine from outside that VLAN, there are two alternatives: using a VPN or assigning public IPs to the VMs.

=== VPN ===

VPNs are currently being tested in the infrastructure. The documentation will be updated as soon as the features are available.

=== Public IPs ===

IFCA provides a pool of public IPs to use them in the cloud service. These can be allocated for your use and assigned to your VMs. Please note that the number of public IPs is limited!

New IPs are created with `nova floating-ip-create`:
{{{
$ nova floating-ip-create
+----------------+-------------+----------+------+
| Ip | Instance Id | Fixed Ip | Pool |
+----------------+-------------+----------+------+
| 193.146.75.142 | None | None | nova |
+----------------+-------------+----------+------+
}}}

You can get the list of the current available IPs with `nova floation-ip-list`:
{{{
$ nova floating-ip-list
+----------------+-------------+----------+------+
| Ip | Instance Id | Fixed Ip | Pool |
+----------------+-------------+----------+------+
| 193.146.75.142 | None | None | nova |
+----------------+-------------+----------+------+
}}}

This newly allocated IP can now be associated to a running VM with `nova add-floating-ip <VM ID> <IP>`:
{{{
$ nova add-floating-ip 9f870141-638e-4eb9-a2fa-ec770d1edb79 193.146.75.142
}}}

The list command will show that the IP is assigned:
{{{
$ nova floating-ip-list
+----------------+--------------------------------------+------------+------+
| Ip | Instance Id | Fixed Ip | Pool |
+----------------+--------------------------------------+------------+------+
| 193.146.75.142 | 9f870141-638e-4eb9-a2fa-ec770d1edb79 | 172.16.2.9 | nova |
+----------------+--------------------------------------+------------+------+
}}}

And you will be able to connect to the machine with this new IP:
{{{
$ ssh -i cloudkey.pem root@193.146.75.142
The authenticity of host '193.146.75.142 (193.146.75.142)' can't be established.
RSA key fingerprint is 29:80:9b:28:e7:8a:00:fe:6c:60:ef:e6:a6:71:33:bd.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '193.146.75.142' (RSA) to the list of known hosts.

[root@testvm ~]#
}}}

IPs can be disassociated from the VM with the `nova remove-floating-ip <VM ID> <IP>`:
{{{
$ nova remove-floating-ip 9f870141-638e-4eb9-a2fa-ec770d1edb79 193.146.75.142
}}}

IPs can be associated/disassociated as many times as needed to any VM you may have running. When no longer needed, release the IP address (i.e. it will no longer be available four your use):
{{{
$ nova floating-ip-delete 193.146.75.142
}}}

== Using the web portal ==

The !OpenStack dashboard lets you perform all the operations described in this manual from your web browser.

=== Creating a Machine with OpenStack ===

Go to http://portal.cloud.ifca.es to access to IFCA !OpenStack.

=== Image and size selection ===
You should launch the image that you want to use (within a list of OS) and click “Launch”. A new popup window will be shown and you have to choose the configuration of the system (requirements, name of the server...).


{{attachment:openstack2.png|alt text|width=600}}
=== Create SSH credentials ===

You must import or create a new key in order to access to that image. To do so go to “Access & Security” tab and click on Create or Import Keypair.

{{attachment:openstack1.png|alt text|width=600}}

=== Connect to the server ===

In order to access throw ssh to the image, you must asign an IP to the instance. Click on “Access & Security” again and select “Allocate IP to project”. Choose the type of IP that you want to use and click “Allocate IP”. After that, you need to link that IP with your new image. Click on the button “Associate IP” of your new IP and select the instance that you have just created.

==== SSH Connection ====

Last step is to download the keypair that you have created or imported and move it to the machine that you will use to conect to the instance. Change permission to 600 and use the following command to connect:

{{{
$ ssh -i clave.pem root@<cloud.image.IP>
}}}

Done

=== VM Lifecycle ===
You can access your VM until you destroy it. Management is allowed thorugh some actions that you can see below:

{{attachment:VMoptions.jpg|alt text|width=200}}


|| Action || Explanation ||
|| View Log || Shows system log in the browser ||
|| Snapshot || Creates a launchable new copy of a VM ||
|| Pause Instance || Pause VM without shutting down it ||
|| Suspend Instance || Shutdown VM. You can keep using it again from the point you suspend it. ||
|| Reboot Instance || Reboot VM ||
|| Terminate Instance || DESTROY VM. Once you click on this action, this VM won't be available anymore. ||
