List command dibawah saya ambil dari blog relasi yang memang sehari-hari mainannnya openstack, ya karena saya udah di network biar gak lupa saya catat di blog saya (sumber tercantum dibawah).
Yup list command ini sangat berguna dalam operational sehari-hari ketika kita menggunakan openstack.
IDENTITY (KEYSTONE)
List all users
$ keystone user-list
List Identity service catalog
$ keystone catalog
IMAGES (Glance)
List images you can access
$ glance image-list
Delete specified image
$ glance image-delete IMAGE
Describe a specific image
$ glance image-show IMAGE
Update image
$ glance image-update IMAGE
Upload kernel image
$ glance image-create --name "cirros-threepart-kernel"
--disk-format aki --container-format aki --is-public False
--file ~/images/cirros-0.3.1~pre4-x86_64-vmlinuz
Upload RAM image
$ glance image-create --name "cirros-threepart-ramdisk"
--disk-format ari --container-format ari --is-public False
--file ~/images/cirros-0.3.1~pre4-x86_64-initrd
Upload three-part image
$ glance image-create --name "cirros-threepart" --disk-format ami
--container-format ami --is-public False
--property kernel_id=$KID-property ramdisk_id=$RID
--file ~/images/cirros-0.3.1~pre4-x86_64-blank.img
Register raw image
$ glance image-create --name "cirros-raw" --disk-format raw
--container-format bare --is-public False
--file ~/images/cirros-0.3.1~pre4-x86_64-disk.img
COMPUTE (Nova)
List instances, check status of instance
$ nova list
List images
$ nova image-list
List flavors
$ nova flavor-list
Boot an instance using flavor and image names (if names are unique)
$ nova boot --image IMAGE --flavor FLAVOR INSTANCE_NAME
$ nova boot --image cirros-0.3.1-x86_64-uec --flavor m1.tiny
MyFirstInstance
Login to instance
# ip netns
# ip netns exec NETNS_NAME ssh USER@SERVER
# ip netns exec qdhcp-6021a3b4-8587-4f9c-8064-0103885dfba2
ssh cirros@10.0.0.2
Note
In CirrOS the password for user cirros is “cubswin:)” tanpa quotes.
Show details of instance
$ nova show NAME
$ nova show MyFirstInstance
View console log of instance
$ nova console-log MyFirstInstance
Set metadata on an instance
$ nova meta volumeTwoImage set newmeta='my meta data'
Create an instance snapshot
$ nova image-create volumeTwoImage snapshotOfVolumeImage
$ nova image-show snapshotOfVolumeImage
PAUSE, SUSPEND, STOP, RESCUE, RESIZE, REBUILD, REBOOT INSTANCE
Pause
$ nova pause NAME
$ nova pause volumeTwoImage
Unpause
$ nova unpause NAME
Suspend
$ nova suspend NAME
Unsuspend
$ nova resume NAME
Stop
$ nova stop NAME
Start
$ nova start NAME
Rescue
$ nova rescue NAME
$ nova rescue NAME --rescue_image_ref RESCUE_IMAGE
Resize
$ nova resize NAME FLAVOR
$ nova resize my-pem-server m1.small
$ nova resize-confirm my-pem-server1
Rebuild
$ nova rebuild NAME IMAGE
$ nova rebuild newtinny cirros-qcow2
Reboot
$ nova reboot NAME
$ nova reboot newtinny
Inject user data and files into an instance
$ nova boot --user-data FILE INSTANCE
$ nova boot --user-data userdata.txt --image cirros-qcow2
--flavor m1.tiny MyUserdataInstance2
Notes
To validate that the file was injected, use ssh to connect to the instance, and look in /var/lib/cloud for the file.
Inject a keypair into an instance and access the instance with that keypair
Create keypair
$ nova keypair-add test > test.pem
$ chmod 600 test.pem
Start an instance (boot)
$ nova boot --image cirros-0.3.0-x86_64 --flavor m1.small
--key_name test MyFirstServer
Use ssh to connect to the instance
# ip netns exec qdhcp-98f09f1e-64c4-4301-a897-5067ee6d544f
ssh -i test.pem cirros@10.0.0.4
Manage security groups
Add rules to default security group allowing ping and SSH between instances in the default security group
$ nova secgroup-add-group-rule default default icmp -1 -1
$ nova secgroup-add-group-rule default default tcp 22 22
NETWORKING (Neutron)
Create network
$ neutron net-create NAME
Create a subnet
$ neutron subnet-create NETWORK_NAME CIDR
$ neutron subnet-create my-network 10.0.0.0/29
BLOCK STORAGE (CINDER)
Used to manage volumes and volume snapshots that attach to instances.
Create a new volume
$ cinder create SIZE_IN_GB --display-name NAME
$ cinder create 1 --display-name MyFirstVolume
Boot an instance and attach to volume
$ nova boot --image cirros-qcow2 --flavor m1.tiny MyVolumeInstance
List volumes, notice status of volume
$ cinder list
Attach volume to instance after instance is active, and volume is available
$ nova volume-attach INSTANCE_ID VOLUME_ID auto
$ nova volume-attach MyVolumeInstance 573e024d-5235-49ce-8332-be1576d323f8 auto
Note
On the Xen Hypervisor it is possible to provide a specific device name instead of automatic allocation. For example:
$ nova volume-attach MyVolumeInstance 573e024d-5235-49ce-8332-be1576d323f8 /dev/vdb
This is not currently possible when using non-Xen hypervisors with OpenStack.
Manage volumes after login into the instance.
List storage devices
# fdisk -l
Make filesystem on volume
# mkfs.ext3 /dev/vdb
Create a mountpoint
# mkdir /myspace
Mount the volume at the mountpoint
# mount /dev/vdb /myspace
Create a file on the volume
# touch /myspace/helloworld.txt
# ls /myspace
Unmount the volume
# umount /myspace
OBJECT STORAGE (Swift)
Display information for the account, container, or object
$ swift stat
$ swift stat ACCOUNT
$ swift stat CONTAINER
$ swift stat OBJECT
List containers
$ swift list
