21 Keystone: Identity Management

22 Keystone: Identity Management centralized identity service central catalog of services Multiple forms of authentication User name and password Token-based systems Amazon Web Services style logins

23 Keystone: Identity Management Login as admin ~]# cat keystonerc_admin export OS_USERNAME=admin export OS_TENANT_NAME=admin export OS_PASSWORD=5ffbe9d2a38d4a48 export OS_AUTH_URL= export \W(keystone_admin)]$ " ~]# source keystonerc_admin ~(keystone_admin)]#

24 Keystone: Identity Management Get a token / troubleshooting auth [root@control ~(keystone_admin)]# keystone token-get Property Value expires T19:22:06Z id e50158f737f14791ae7831c955524de2 tenant_id b4468adacd92f2f376bc9 user_id f4270a7b46af a02d9cd49d

25 Keystone: Identity Management Add a User [root@control ~]# keystone user-create --name radez --pass supersecretpass id: d654b9b9a8cc38b10284a52 [root@control ~]# keystone role-create --name role1 id: 8ab4a afbafc0f95a47170 [root@control ~]# keystone tenant-create --name tenant1 Id: 427c01f33fcf4feb930f26dd550a14e0

26 Keystone: Identity Management Add a User [root@control ~]# keystone user-role-add --user-id radez --role-id role1 --tenant-id tenant1 [root@control ~]# keystone user-list [root@control ~]# keystone role-list [root@control ~]# keystone tenant-list [root@control ~]# keystone user-role-list [root@control ~]# keystone endpoint-list

27 Keystone: Identity Management Login as user ~]# cp keystonerc_admin keystonerc_radez export OS_USERNAME=radez export OS_TENANT_NAME=tenant1 export OS_PASSWORD=supersecretpass export OS_AUTH_URL= export \W(keystone_radez)]$ " ~]# source keystonerc_radez ~(keystone_radez)]# keystone token-get ~(keystone_radez)]# source keystonerc_admin ~(keystonerc_admin)]#

29 Glance: Image Management

30 Glance: Image Management registry for virtual machine images images used as templates for new servers Add an image ~]# glance image-create --name cirros --is-public 1 --disk-format qcow2 --container-format bare --file /mnt/cirros x86_64-disk.img id: d3d1f38e-3f2c-4f45-91e1-cb4535f62d10 [root@control ~]# glance image-list

31 Glance: Image Management Image Building Oz appliance-creator Native glance builder in the works Manually (launch installer, import before first boot) Build Notes: Include cloudinit for post boot configuration

32 Glance: Image Management Add an image

33 Neutron: Networking

34 Neutron: Networking networking as a service built in modular architecture Features Single or Multiple host deployment virtual network, subnet, and port abstractions Plugin architecture supports many network technologies

35 Neutron: Networking Add a network

36 Nova: Instance Management

37 Nova: Instance Management manages virtual machines on nodes provides virtual servers on demand Design Features Designed to scale horizontally Designed for standard hardware

38 Nova: Instance Management Boot an instance ~]# nova flavor-list ~]# nova keypair-add --pub-key.ssh/id_rsa.pub mykey ~]# nova keypair-list mykey 84:6e:28:d3:75:17:ab:25:4d:f3:0d:61:93:55:ee:e2 ~]# nova image-list ~]# nova boot --flavor 1 --key_name mykey --image cirros my_instance [root@control ~]# nova list

39 Nova: Instance Management Boot an Instance

40 Nova: Instance Management Communicate with the instance ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static NM_CONTROLLED="no" ONBOOT=yes TYPE=Ethernet ~]# cat /etc/sysconfig/network-scripts/ifcfg-br-ex DEVICE=br-ex BOOTPROTO=static IPADDR= GATEWAY= NETMASK= NM_CONTROLLED="no" ONBOOT=no

41 Nova: Instance Management Communicate with the instance ~]# ovs-vsctl add-port br-ex eth0 && service network restart ~]# ovs-vsctl show Bridge br-ex Port br-ex Interface br-ex type: internal Port "eth0" Interface "eth0"

42 Nova: Instance Management Communicate with the instance ~]# ping PING ( ) 56(84) bytes of data. 64 bytes from : icmp_seq=2 ttl=63 time=0.668 ms ~]# ssh The authenticity of host ' ( )' can't be established. RSA key fingerprint is 38:49:f2:67:80:11:31:84:1f:b1:79:df:5f:e4:e5:f7. Are you sure you want to continue connecting (yes/no)? Yes Warning: Permanently added ' ' (RSA) to the list of known hosts. $

43 Nova: Instance Management Allow external access

44 Cinder: Block Storage

45 Cinder: Block Storage manages persistent block storage volumes snapshots can be taken Create and attach a volume [root@control ~]# cinder create 1 id: 4d6cbb1f c7-8ae0502e6de5 [root@control ~]# nova volume-attach my_instance 4d6cbb1f c7-8ae0502e6de5 auto

46 Cinder: Block Storage Mount a volume [root@control ~]# ssh -i.ssh/id_rsa root@ my_instance$ sudo -i my_instance# mkfs.ext4 /dev/vdb my_instance# mkdir -p /mnt/volume my_instance# mount /dev/vdb /mnt/volume my_instance# touch /mnt/volume/test.txt my_instance# umount /mnt/volume [root@control ~]# nova volume-detach my_instance 4d6cbb1f c7-8ae0502e6de5

47 Cinder: Block Storage Create, attach and mount a volume

48 Swift: Object Storage

49 Swift: Object Storage Install Swift /root/packstack-answers txt CONFIG_SWIFT_INSTALL=n ~]# packstack --answer-file packstack.txt Generating a packstack answer file [root@control ~]# packstack --gen-answer-file answers.txt

50 Swift: Object Storage allows users to store and retrieve files distributed architecture to allow for horizontal scaling provides redundancy as failure-proofing data replication is managed by software

51 Swift: Object Storage Upload an object ~]# swift stat ~]# swift list ~]# swift upload test packstack-answers.txt ~]# swift list ~]# swift list test ~]# swift upload test /etc/motd ~]# swift list test

52 Swift: Object Storage Create a container & upload an object
