EGI FedCloud BIFI

Para utilizar los recursos EGI FedCloud es necesario un certificado grid. Si ya lo tienes

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}'
    CESGA
    NCG-INGRID-PT
    MK-04-FINKICLOUD
    CESNET-MetaCloud
    BIFI
    BIFI
    INFN-PADOVA-STACK
    FZJ
    CETA-GRID
    IFCA-LCG2
    IISAS-GPUCloud
    UPV-GRyCAP
    IISAS-FedCloud
    JINR-LCG2
    RECAS-BARI
    INDIGO-CATANIA-STACK
    INFN-CATANIA-NEBULA
    INFN-CATANIA-STACK
    IN2P3-IRES
    UA-BITP
    HG-09-Okeanos-Cloud
    SCAI
    CYFRONET-CLOUD
    100IT
    
  • 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:
    [user@ui ~]$ occi --endpoint $ENDPOINT --action list --resource os_tpl --auth x509 --user-cred $X509_USER_PROXY --voms

  • Obtenemos lista de flavours disponibles en el site :
    [user@ui ~]$ occi --endpoint $ENDPOINT --action list --resource resource_tpl --auth x509 --user-cred $X509_USER_PROXY --voms

    http://schemas.openstack.org/template/resource#m1-small-ephemeral
    
  • 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}

  • 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}
