=== Creating a machine === To create a machine you have to perform several steps: * Decide which of the prebuilt images you are going to use. * Decide which with of the available sizes is suitable for you. * Decide (and create if not ready) with keypair should be used to connect to the machine. ==== Image and size selection ==== There are several pre-built images available. To check them, use the `euca-describe-images` command: {{{ $ euca-describe-images IMAGE ami-00000008 None (cloudpipe) available public machine instance-store IMAGE ami-00000007 None (Debian Wheezy (2011-08)) available public machine instance-store IMAGE ami-00000006 None (lucid-server-uec-amd64.img) available public machine instance-store IMAGE ami-00000003 None (Scientific Linux 5.5) available public machine instance-store IMAGE ami-00000001 None (Scientific Linux 5.5) available public machine instance-store }}} Once you have decided with image to use, you can write down its identifier (ami-XXXXXXXX). You also have to decide with image size to use from the following: || '''Name''' || '''Memory''' || '''# CPU''' || '''Local storage''' || '''Swap''' || || m1.tiny || 512MB || 1 || 0GB || 0GB|| || m1.small || 2048MB || 1 || 20GB || 0GB|| || m1.medium || 4096MB || 2 || 40GB || 0GB|| || m1.large || 8192MB || 4 || 80GB || 0GB|| || m1.xlarge || 16384MB || 8 || 160GB || 0GB|| ==== Create SSH credentials ==== For most of the users this is a one-time step (although you can create as much SSH credentials as you want). You have to create an SSH-keypair so as to inject it to the newly created machine with the following command (it will create a keypair named `cloudkey` and store it under `~/.cloud/cloudkey.pem`): {{{ $ euca-add-keypair cloudkey > ~/.cloud/cloudkey.pem }}} Make sure that you keep safe the file `~/.cloud/cloudkey.pem`, since it will contain the private key needed to access your cloud machines. You can check the name later with the `euca-describe-keypairs` command. ==== Launching the instance ==== To launch the instance, you have to issue `euca-run-intances`, specifying: * wich keypair to use (in the example `cloudkey`). * wich size should be used (in the example `m1.tiny`). * with image should be used (in the example `ami-00000001`). {{{ $ euca-run-instances -k cloudkey -t m1.tiny ami-00000001 RESERVATION r-1zdwog0m ACES default INSTANCE i-00000048 ami-00000001 scheduling cloudkey (ACES, None) 2011-09-02T12:19:41Z None None }}} You can check its status with `euca-describe-instances` {{{ $ euca-describe-instances i-00000048 RESERVATION r-vmfu1xq2 ACES default INSTANCE i-00000048 ami-00000001 172.16.1.8 172.16.1.8 blocked cloudkey (ACES, cloud01) 0 m1.tiny 2011-09-02T12:15:32Z nova }}} ==== Stopping the server ==== === Advanced topics === ==== Attach to the project's VPN ==== ==== Manage multiple credentials ==== and checking that `NOVA_API`, `NOVA_CERT`, `NOVA_PROJECT`, `NOVA_URL`, `NOVA_USERNAME`, |
Cloud Computing at IFCA
Contents
1. Introduction
IFCA uses OpenStack for managing the cloud service. You may get access upon request. There are several ways to access the infrastructure, namely:
OpenStack API, that can be used with the different command line interfaces.
OCCI API, that can be used with rOCCI client
2. Documentation
The official, up to date documentation can be found in the following link:
Plase refer to that documentation, since it contains the most up to date and accurate documentation for using OpenStack resources.
Important: Do not hesitate in opening a ticket if you notice problems using cloud services.
