This chapter describes how a cloud user can manage different resources in an account by using the APIs and CLI. It also includes a basic example for each action that a cloud user can perform to manage these resources by using the cloud infrastructure API and cloud infrastructure CLI.
For a complete reference and other examples that use the cloud infrastructure API and CLI, see also:
Note:
For more information about the cloud infrastructure Java client API, see the Javadoc files included in the package of the API.This section describes the following different resources that a cloud user can manage by using the APIs and CLI:
Access keys – Used to manage cloud user access to an account. See "Managing Account Access" for more information.
Virtual networks (vNets) – Used for network connectivity of vServers. See "Managing Virtual Networks" and "Managing vIP Addresses" for more information.
Server templates – Used to designate the operating system and how it is installed when creating the vServer. See "Managing Server Templates" for more information.
Virtual storage – Includes volumes that can be attached to vServers, and snapshots that capture the current state of a volume for different purposes. See "Managing Storage".
Virtual servers (vServers) – Provides the outward interface of a standalone operating system. A vServer has its own identity, local storage, interfaces, and configuration that exist for the full lifetime of the vServer. See "Managing vServers".
These resources have both attributes and tags:
Attributes – When a resource is created, it has a set of attributes to describe it. These attributes include defined entities such as name, description, and size. Some of these attributes can be modified. See "Managing Attributes of an Account Resource".
Tags – Used to bind cloud user-specific information to account resources. See "Managing Tags".
Note:
Availability and management of some of these resources might vary depending on the configuration of the vDC. Contact your cloud administrator for more information.The status attribute is displayed when viewing information or attributes of any of the following account resources:
vServers
vNets
Server templates
Volumes
Snapshots
Distribution groups
This section explains the meaning and usage of the status attribute. The status attribute of an account resource is useful to know because:
When a cloud user creates a new account resource, the status indicates if the creation job has completed or the account resource creation is still in progress.
The status field indicates whether an account resource is in a usable state or in an unusable state.
An account resource can have one of the following different states:
Pending status – Resource creation is in progress.
SCHEDULED – Indicates that the creation job is in progress. Wait for the resource to transition from this state before using it.
FAILED – Indicates that the creation of the resource failed. A failed job is reflected in the user interface (UI).
Healthly status – The resource exists. The following values indicate that a resource is usable.
OK – Indicates that the resource is healthy and usable as normal.
INFO – Indicates that the resource is healthy but an informational event is awaiting attention in the UI.
Note:
For vServer resources, the healthy status values of "OK", "INFO", and "UNKNOWN" is swapped with the runtime state of the vServer. Instead of OK or INFO, a vServer can present one of the following status: RUNNING, BLOCKED, PAUSED, SHUTDOWN, DYING, CRASHED, NOSTATE, SUSPENDED, INSTALLING, SHUTDOWNDETACHED, MIGRATING_SRC, and MIGRATING_DST. Of these running vServer states, BLOCKED, DYING, CRASHED, NOSTATE, and FAILED can be regarded as unhealthy.Unhealthy status – A resource exists. The following values indicate that a resource might not be usable. This does not apply to the WARNING state.
Note:
Which status applies depends on the resource; for example, NEEDS_POWERON does not apply to a volume.CRITICAL
DECONFIGURED
FAULTED
MAINTENANCE
NON_RECOVERABLE
UNCONFIGURED
UNINITIALIZED
UNKNOWN
NEEDS_POWERON
Operations that delete resources might observe a state transition until the point is reached whereby the resource is no longer visible. For example, the process of terminating a vServer can exhibit a transition to the vServer run state SHUTDOWNDETACHED before the resource is removed.
A delete operation could also fail, in which case the resource must transition to one of the unhealthy states in the preceding list.
User management is provided by a central service of Oracle Enterprise Manager Ops Center. The Web service is the entry point for cloud user requests. The Web service uses access keys to authenticate and authorize cloud user requests. A cloud user must create an access key for an account to perform any action for the resources allocated in that account.
An access key consists of an ID, a private key, a public key, and an authentication target account. The private key is used on the client side to sign HTTP requests. The Web service uses the public key to verify incoming HTTP requests and to authenticate the calling user. After creation, the private key is given to the user. The cloud user is responsible for limiting the access to the private key.
The access key management functionality of the Web service is provided by an extra servlet that allows user name and password authentication.
The APIs and CLI provide operations for:
Note:
When using the APIs and CLI, an option is available to manage access keys on behalf of another cloud user. This option is available only to cloud administrators.A cloud user needs an access key to get access to an account and to authenticate all other HTTP requests for an account. Once an access key is created, the public key is stored in the server-side database to verify the incoming HTTP requests and to authenticate the calling user.
When creating an access key by using the CLI, the private key is provided to the user after the access key creation.
If using the RegisterAccessKey by using the API directly, then the cloud user supplies the public key portion of a key pair and manages the private key himself.
Whichever access key creation method is used, a unique access key identifier, such as AK_5, is supplied to the cloud user for direct use of the API. The cloud user is responsible for limiting the access to the private key.
The cloud infrastructure API actions and the cloud infrastructure CLI command required to create an access key are:
| Cloud Infrastructure API Action | Cloud Infrastructure CLI Command |
|---|---|
| RegisterAccessKeyRequest | akm-create-access-key |

Virtual Network management involves the network connectivity of the vServers in an account. Virtual Network management also includes the connectivity of vServers to an external network.
A vServer is a member of one or more vNets of two different types:
Private vNet – A private vNet is created based on the private network from the network domain of the virtual datacenter (vDC). Private vNets are only accessible within an account. All vServers that have membership of a private vNet in common can communicate freely through that subnet.
Public network – This type of networks can be shared among a number of accounts in a vDC. vServers members of public networks also have external communication beyond vDCs and can be used to host public services.
The membership of a vServer in one or more vNets can be specified only at vServer creation time.
The APIs and CLI provide operations for:
A cloud user can create private vNets according to the user requirements and within the limits of the account quota.
A public network available in an account is visible to cloud users. However, a cloud user cannot create a public network. The number of public network IP addresses allocated to the cloud user is controlled by the cloud administrator.

A virtual IP (vIP) address is a statically configured IP address that is owned by a user.
A vIP address can be allocated from a public network or private vNet. The allocated vIP address is bound to an account and can be associated with a vServer. The vIP address association is performed at vServer creation time. vIP addresses remain bound to vServers even when the vServer is stopped. vIP addresses are not disassociated until the vServer is deleted.
The APIs and CLI provide operations for:
A cloud user can allocate a vIP address from a public network or a private vNet. When creating a vServer, cloud users can statically assigned the allocated vIP address to the vServer.

A server template is used to designate the operating system and how it is installed when creating the vServer. Server templates are specific to the processor architecture of the server pool and the virtualization type and might be prebuilt images or identify the operating system distribution.
Server templates are bound to a specific account. Server templates are immutable entities and cannot be changed later, other than changing the name or description.
You require a server template for creating vServers. It has the following attributes:
Minimum and default vServer type
User and unique name
Version
Owner
Location
HA enabled
Life cycle aware
A new server template can be uploaded as follows:
Based on an existing vServer
From a single virtual machine template
From an assembly. When you upload an assembly, snapshots can be also created as result
The APIs and CLI provide operations for:
A cloud user can save a server template from a stopped vServer. When a user creates a vServer based on a server template, it is common to install additional software or to configure certain aspects that can be conserved and reused. To conserve the state, the user must save the vServer as a new server template.
The cloud infrastructure API action and the cloud infrastructure CLI command required to upload a server template from a vServer are:

A cloud user can upload a server template based on an assembly.
An assembly is a collection of interrelated software appliances that can include a configuration of multiple virtual machines with their virtual disks and their interconnectivity. An assembly is contained in a single .ova (Open Virtualization Format Archive) file. The assembly file must be accessible through a URL.
When you upload an assembly, snapshots might be also created as result. When an assembly contains multiple virtual machines, each virtual machine is unpacked into its own server template. Each template created has a tag set to indicate which assembly it belongs to. This tag name is assemblyKey, and its value is the original assembly ID returned from this action.

Volumes and snapshots are the two types of storage devices that are managed by a cloud user.
The virtual block storage devices are called volumes. Volumes are serially shareable and can be attached to or detached from a vServer.
A snapshot captures the current state of a volume. Snapshots are immutable.
The APIs and CLI provide operations for:
A cloud user can create a shared or non-shared empty volume with a given size. A cloud user can also create a shared or nonshared volume from a snapshot. The new volume can be attached to vServers. Shared volumes can be attached to more than one vServer.
The cloud infrastructure API action and the cloud infrastructure CLI command required to create a volume are:
| Cloud Infrastructure API Action | Cloud Infrastructure CLI Command |

A cloud user can attach volumes to an existing vServer. A cloud user might also attach volumes to a vServer during the vServer creation process. The volume attached is available as a device in the vServer. Depending on the virtualization type of the virtual datacenter, the cloud user might need to stop the vServer before attaching a volume.
The cloud infrastructure API action and the cloud infrastructure CLI command required to attach a volume to a vServer are:
| Cloud Infrastructure API Action | Cloud Infrastructure CLI Command |
|---|---|
| AttachVolumesToVserverRequest | iaas-attach-volumes-to-vserver |
Example 3-37 Attaching a volume to a vServer using the Cloud Infrastructure API

A cloud user can detach a volume from a vServer. After it is detached, the volume is no longer available as a device in the vServer. Depending on the virtualization type of the vDC, cloud user might need to stop the vServer before detaching a volume.
Caution:
Before detaching a volume from a vServer, ensure that the disk being detached is not longer in use to avoid services instability or disk data corruption. Ensure that the vServer properly unmounts the device for the volume; otherwise, data loss or file system corruption might occurThe cloud infrastructure API action and the cloud infrastructure CLI command required to detach a volume from a vServer are:
| Cloud Infrastructure API Action | Cloud Infrastructure CLI Command |
|---|---|

Snapshot creation and management is available if it is supported by the storage of the vDC.
Creating a snapshot serves two main purposes:
A cloud user can create a snapshot of a volume or, a snapshot can exist as result of uploading an assembly.
There are four types of exposed disks in an assembly's template. When snapshots are created from an assembly, three of the disk type are presented to cloud users as snapshots. This allows cloud users to optionally create a shared volume from the snapshot. The three exposed disks are:
Public Populated – An extra disk with data already present.
Private Raw – Dynamically created as an empty disk with a size but no disk data.
Shared Raw – Dynamically created as an empty disk, with a size but no disk data.
The cloud infrastructure API action and the cloud infrastructure CLI command required to create a snapshot of an existing volume are:
| Cloud Infrastructure API Action | Cloud Infrastructure CLI Command |
|---|---|
| CreateSnapshotRequest | iaas-create-snapshot |
Example 3-43 Creating a snapshot using the Cloud Infrastructure API

A vServer has its own identity, local storage, interfaces, and configuration that exist for the lifetime of the vServer. vServers are created based on a server template and vServer types. A vServer type defines hardware characteristics of the vServer, such as CPU, memory size, and the network bandwidth.
Each vServer is a member of one or more vNets that define the network connectivity. A vServer has temporary local storage. For hard disk storage, the associated volume is used. A vServer can have one or more volumes attached.
The APIs and CLI provide operations for:
A cloud user can get information about all available vServer types for an account. The cloud user can restrict the vServer types included in the result by specifying filters.

A cloud user can create a single vServer or multiple vServers at once based on a server template. When a vServer is created, it is automatically started.
When creating a single vServer, the cloud user must use an allocated vIP address. When creating multiple vServer an IP address is automatically assigned from each specified vNets.
When a cloud user creates a vServer, the following resources are required:
A vServer type
A server template
One or more vNets
Depending on the needs of the user and the virtualization type of the vDC, a cloud user can also specify the following resources:
A key pair
One or more volumes
A Distribution group
Additionally to the resources listed, a cloud user might specify the following values when creating a vServer:
A hostname to override vServer default internal host name, which is same as vServer name.
A root password
One or more messages for the vServer
Enable or disable high availabitility
When creating a vServer, a cloud user might choose to enable or disable the high availability feature for the vServer. By default, the value of this option is determined by the HighAvailabilityDefault capability of the vDC. If a cloud user chooses not to use the default value, then an option is available to specify a different value; in this case, the HighAvailabilityUserControl capability of the vDC must be enabled. Cloud users can also enable or disable high availability for an existing vServer, see "Modifying Attributes of an Account Resource".
