Aliyun Swift OpenAPI

Aliyun Swift API based on Perfect. All implementations are based on Alibaba Cloud REST API.

Current Implementation

All structures are JSON convertible.

Prepare Credentials

let access = AcsCredential()
access.id = "an easy name to remember the key"
access.key = "Your AccessKeyId"
access.secret = "Your AccessKeySecret"

Query Regions

let ecs = ECS(access: access)
ecs.describeRegions { regions in
}

// where regions is [Region]
// region.id is the actual usable RegionId
// region.name is a Chinese description

Query Security Groups

ecs.describeSecurityGroups(region: "RegionId") { securityGroups, message in

}

Callback parameter securityGroups is [SecurityGroup], with properties mapping as below:

Property	Alibaba Cloud Official Document Name
id	SecurityGroupId
name	SecurityGroupName
remark	Description
tags	Tags
creationTime	CreationTime
availableInstanceAmount	AvailableInstanceAmount
vpcId	VpcId

Key Pairs

Create a Key Pair

ecs.createKeyPair(region: "RegionId",
	name: "Name of the Key Pair, will be useful for instance creation") { keyPair, msg in 
// should save the keyPair.key immediately as a .pem file with 400 mod.
}

Where keyPair is a AcsKeyPair class:

Property	Alibaba Cloud Official Document Name
name	KeyPairName
fingerPrint	KeyPairFingerPrint
key	PrivateKeyBody

Delete Key Pairs

let keypairs = ["keypair1 to delete", "keypair2 name", ... ]

ecs.deleteKeyPairs(region: "RegionId", keyNames: keypairs) { 
	success, message in
	// success should be true to confirm the deletion.
}

Check Support Instance Types

Note not all instance types are available throughout the regions. ecs.describeImageSupportInstanceTypes() may help a bit, but still not 100% guarantee the availabilities.

ecs.describeImageSupportInstanceTypes(region: "cn-hongkong", 
	imageId: "ubuntu_16_0402_64_40G_base_20170222.vhd") { 
	types, msg in
	
}

It will return an array like [InstanceType], with information properties below:

Property	Alibaba Cloud Official Document Name
id	InstanceTypeId
typeFamily	InstanceTypeFamily
cpu	CpuCoreCount
memory	MemorySize

Instance

CreateInstance()

let ecs = ECS(access: access)
let tags = ["Perfect":"1"]
// you have to pick out the security group id
// by the above security group method before creating instances.
let sid = "sg-j6c58xjb4po9jq2hsc0u"
ecs.createInstance(region: "cn-hongkong", securityGroupId: sid, name: "PT-01", description: "PerfectTemplate Test Instance", keyPair: "TestKey", tags: tags) { 
	instanceId, msg in

}

allocateIP()

⚠️Note⚠️ The newly created instance will not be connected unless allocate a public ip:

ecs.allocateIP(instanceId: id) { 
	ipAddress, msg in
	if let ip = ipAddress {
		print("ssh -i /path/to/keypair.pem root@\(ip)")
	}

Load Instance Status

Even a successful instance creation with an instanceId returned, the status would not be available in the first 5 seconds after the creation.

ecs.loadInstances(region: "cn-hongkong", tags: ["Perfect":"1"]) { 
	instanses, msgs in
}

The instances array [Instance] described as below:

Property	Alibaba Cloud Official Document Name	Property	Alibaba Cloud Official Document Name
id	InstanceId	name	InstanceName
remark	Description	imageId	ImageId
region	RegionId	zone	ZoneId
cpu	CPU	memory	Memory
type	InstanceType	typeFamily	InstanceTypeFamily
host	HostName	status	Status
securityGroups	SecurityGroupIds	ipPublic	PublicIpAddress.ipAddress
maxBandwidthIn	InternetMaxBandwidthIn	maxBandwidthOut	InternetMaxBandwidthOut
chargeTypeInternet	InternetChargeType	chargeTypeInstance	InstanceChargeType
creationTime	CreationTime	ipPrivate	InnerIpAddress.ipAddress
networkType	InstanceNetworkType	operationLocks	OperationLocks
deviceAvailable	DeviceAvailable	ioOptimized	IoOptimized
expiration	ExpiredTime	keyPairName	KeyPairName

Start an instance

ecs.startInstance(instanceId: id) { 
	success, message in
	// success will be true if the instance started.
}
