可以将自动扩展组配置为使用启动模板而不是启动配置。我想使用它，因为当我使用启动配置配置自动扩展组时，我无法设置混合实例策略（ondemand + spot实例）。
我用这样的配置创建了启动模板（名称'test'）：
AMI Ubuntu 16,
some security groups and IAM Role with EC2, AutoScaling and CodeDeploy full access
and all other settings in default *Not specified* state.
Launch Template ID lt-0e1111
Default Version Number 1
Launch Template Name test

Spot expiry date -
Spot block duration Not specified
Shutdown behavior Not specified
Termination Protection Not specified
Placement Group Name Not specified
Tenancy Not specified
Tenancy Affinity Not specified

然后我用该启动模板创建一个AutoScaling组。这是我的自动缩放组配置：
Launch Template test
Launch Template Version 1
Launch Template Description -
Instance Types -
Spot Diversity 0
Optional On-Demand Base 0
On-Demand Percentage 0%
Desired Capacity 1
Min 1
Max 1
Availability Zone(s) eu-central-1a
Subnet(s) subnet-53075e38

Service-Linked Role arn:aws:iam::11111111111:role/aws-service-role/autoscaling.amazonaws.com/AWSServiceRoleForAutoScaling
我选择时似乎设置了这样的配置
*Fleet Composition - Adhere to the launch template
The launch template determines the instance type and purchase option (On-Demand or Spot).*
选项和我的lauch模板配置如上所述。
所以我的自动缩放组中没有斑点。
然后我使用这样的配置在其中配置CodeDeploy应用程序'Application'和DeploymentGroup'DN_TEST'：
Deployment type Blue/green
Service role ARN arn:aws:iam::11111111111111:role/CodeDeployRole
Deployment configuration CodeDeployDefault.AllAtOnce
Rollback enabled -
Environment configuration: Amazon EC2 Auto Scaling groups -> Name 'test'
好的，在设置完所有内容后，我在Autoscaling组中将所需的实例数设置为1，并在我的“test”组中生成新的按需实例。
我现在使用AWS CLI命令启动蓝绿部署：
aws deploy create-deployment --application-name Application --s3-location bucket=codedeploybucket,key=application,bundleType=zip --deployment-group-name DG_TEST
我可以看到我的绿色舰队中出现了带有相同模板的新自动缩放组。
所以我们只是检查了所有服务是否按预期工作。
现在我想稍微调整一下我的自动缩放组配置，以便在其中混合ondemand和spot实例：
Fleet Composition - Combine purchase options and instances
Choose a mix of On-Demand Instances and Spot Instances and multiple instance types. Spot Instances are automatically launched at the lowest price available.
Instance Types:
t2.nano (1vCPUs, 0.5GiB)
t2.small (1vCPUs, 2GiB)
t2.micro (1vCPUs, 1GiB)
Maximum Spot Price - Use default (recommended)
Spot Allocation Strategy - Diversify Spot Instances across your 2 lowest priced instance types per Availability Zone
Optional On-Demand Base - Designate the first 0 instances as On-Demand
On-Demand Percentage 50% On-Demand and 50% Spot
Desired Capacity 1
Min 1
Max 1
我保存并尝试使用相同的AWS CLI命令
aws deploy create-deployment --application-name Application --s3-location bucket=codedeploybucket,key=application,bundleType=zip --deployment-group-name DG_TEST
现在，我的部署失败了，并发表了这样的评论：
The following validation error occurred: Valid requests must contain either LaunchTemplate, LaunchConfigurationName, InstanceId or MixedInstancesPolicy parameter. (Service: AmazonAutoScaling; Status Code: 400; Error Code: ValidationError; Request ID: 11111114-2b2b-11e9-93b7-11111111111)
另一个奇怪的事情是，如果我将启动模板配置为仅使用斑点：
Launch Template ID lt-00dc4c187d1111159
Default Version Number 1
Launch Template Name test2
Owner
arn:aws:iam::179961111910:user/itsp

并在我的自动缩放组中使用该选项：
*Fleet Composition - Adhere to the launch template
The launch template determines the instance type and purchase option (On-Demand or Spot).*
然后在相同的部署命令后，我在CodeDeploy中收到另一个错误（部署失败原因）：
The IAM role arn:aws:iam::179966034910:role/CodeDeployRole does not give you permission to perform operations in the following AWS service: AmazonAutoScaling. Contact your AWS administrator if you need help. If you are an AWS administrator, you can grant permissions to your users or groups by creating IAM policies.
这绝对不是这种情况，因为CodeDeploy的角色具有完整的EC2，Autoscaling和CodeDeploy访问权限。
我做错了什么或者是错误？如何使用启动模板使用codedeploy配置混合自动缩放组（ondemand + spot实例）？提前致谢！
使用CodeDeploy和LaunchTemplates时，我遇到了类似的问题。 看起来CodeDeploy仍然不支持LaunchTemplates。
我们必须坚持LaunchConfigurations。他们仍然不支持版本控制，但在大多数情况下，它们几乎相同：/
在将LaunchConfigurations迁移到LaunchTemplates时，我无法找到AWS记录的那个小不兼容问题......但是可以找到here更多信息。
SHEERS！
