EGI FedCloud BIFI

EGI FedCloud guía de usuario

Para el uso de recursos de computación cloud en BIFI EGI utilizaremos la imagen EGI Ubuntu 14.04. Para ello debemos configurar una serie de variables: ENDPOINT, OS_TPL, RES_TPL. Estas variables se pueden obtener bien desde el apartado Availability & Usage de la aplicación indicada o con siguientes comandos:

Obtenemos la lista de sites disponibles en EGi FedCloud?:

[user@ui ~]$ ldapsearch -x -H ldap://lcg-bdii.cern.ch:2170 -b GLUE2GroupID=grid,o=glue "GLUE2ServiceType=IaaS" | grep GLUE2ServiceAdminDomainForeignKey | awk '{print $2}'

Obtenemos la variable ENDPOINT :

[user@ui ~]$ ldapsearch -x -H ldap://lcg-bdii.cern.ch:2170 -b GLUE2DomainID=BIFI,GLUE2GroupID=grid,o=glue GLUE2EndpointInterfaceName=OCCI | grep GLUE2EndpointURL |  awk {'print $2'}
http://server4-epsh.unizar.es:8787
http://server4-eupt.unizar.es:8787

Generamos un proxy válido para poder operar en la infraestructura EGI FedCloud :

[user@ui ~]$ voms-proxy-init -voms fedcloud.egi.eu --rfc
Enter GRID pass phrase for this identity:
Contacting voms2.grid.cesnet.cz:15002 [/DC=org/DC=terena/DC=tcs/C=CZ/ST=Hlavni mesto Praha/L=Praha 6/O=CESNET/CN=voms2.grid.cesnet.cz] "fedcloud.egi.eu"...
Remote VOMS server contacted succesfully.


Created proxy in /tmp/x509up_u15139.

Your proxy is valid until Wed May 04 22:59:34 CEST 2016

Configuramos las variables de entorno ENDPOINT y X509_USER_PROXY :

[user@ui ~]$ export ENDPOINT=http://server4-epsh.unizar.es:8787
[user@ui ~]$ export X509_USER_PROXY=/tmp/x509up_u15139

Obtenemos la lista de imágenes disponibles en el site:

Obtenemos lista de flavours disponibles en el site :

Configuramos la imagen del Ubuntu 14.04 y seleccionamos un flavour para esa imagen :

[user@ui ~]$ export OS_TPL=http://schemas.openstack.org/template/os#b14b85ee-782b-43bf-8616-6bf2f1665949
[user@ui ~]$ export RES_TPL=http://schemas.openstack.org/template/resource#m1-small

Una vez configuradas la variables de entorno podemos crear, monitorizar y destruir nuestra VM :

Creamos un par clave publica-privada para conectarnos a las maquinas virtuales (VM) que creemos :
```
[user@ui ~]$ ssh-keygen -t rsa -b 2048 -f tmpfedcloud
```

Configuramos la VM utilizado cloud config:

[user@ui ~]$ cat > tmpfedcloud.login << EOF
#cloud-config
users:
  - name: cloudadm
    shell: /bin/bash
    sudo: ALL=(ALL) NOPASSWD:ALL
    lock-passwd: true
    ssh-import-id: cloudadm
    ssh-authorized-keys:
      - `cat tmpfedcloud.pub`
EOF

Creamos la VM :

[user@ui ~]$ VM_ID=$(occi --endpoint $ENDPOINT --auth x509 --user-cred $X509_USER_PROXY --voms --action create --resource compute --attribute occi.core.title="MyFirstVM" --mixin $OS_TPL --mixin $RES_TPL --context user_data="file://$PWD/tmpfedcloud.login")

Obtenemos información de sus características, como su dirección IP:

[user@ui ~]$ occi --endpoint $ENDPOINT --auth x509 --user-cred $X509_USER_PROXY --voms --action describe --resource ${VM_ID}

    location:     /b14b85ee-782b-43bf-8616-6bf2f1665949/

Como la IP no es pública, es necesario ejecutar el siguiente comando :

[user@ui ~]$ occi --endpoint $ENDPOINT --auth x509 --user-cred $X509_USER_PROXY --voms --action link --resource ${VM_ID} --link /network/public
http://server4-epsh.unizar.es:8787/network/interface/1341dce4-8dd5-412c-a2b8-14466dc0ebf4_155.210.198.164

Nos conectamos a la VM por medio de ssh haciendo uso de la clave privada que hemos generado con anterioridad:
```
[user@ui ~]$ ssh -i tmpfedcloud cloudadm@155.210.198.164
```

Finalmente una vez utilizada la VM la destruimos :

[user@ui ~]$ occi --endpoint $ENDPOINT --auth x509 --user-cred $X509_USER_PROXY --voms --action delete --resource ${VM_ID}
