在通过Cloudformation创建AWS::ECS::Service
的过程中,出现错误:Model validation failed
该错误与#HealthCheckGracePeriodSeconds
和其他一些属性有关。错误详细信息为:expected type: Number, found: String
。
在yaml中,它已经是一个数字。我不清楚发生了什么问题。已经尝试将其声明为字符串或类型为Number的参数。
我需要一些提示,因为此时我陷入困境。
错误是:
Model validation failed
(
#/HealthCheckGracePeriodSeconds: expected type: Number, found: String
#/DesiredCount: expected type: Number, found: String
#/DeploymentConfiguration/MaximumPercent: expected type: Number, found: String
#/DeploymentConfiguration/MinimumHealthyPercent: expected type: Number, found: String
)
template.yaml中的定义是:
ServiceDefinition:
Type: AWS::ECS::Service
Properties:
ServiceName: !Ref ServiceName
Cluster: !Ref ClusterName
TaskDefinition: !Ref TaskDefinition
DeploymentConfiguration:
MinimumHealthyPercent: 100
MaximumPercent: 200
DesiredCount: 1
HealthCheckGracePeriodSeconds: 60
LaunchType: FARGATE
NetworkConfiguration:
AwsVpcConfiguration:
AssignPublicIP: ENABLED
SecurityGroups: !FindInMap [Env2SecurityGroups, !Ref AWS::AccountId, securitygroup]
Subnets: !FindInMap [Env2PublicSubnets, !Ref AWS::AccountId, subnets]
答案 0 :(得分:2)
该错误是由于SecurityGroups
和Subnets
导致格式错误而引起的。
要提取subnets
和securitygroups
,使用了FindInMap
函数。此结果必须是列表。这可以使用Split
函数来实现。
不幸的是,格式错误会导致完全错误的错误消息。
声明这样的映射:
Mappings
Env2SecurityGroups:
'111111111111':
securitygroup: 'sg-1111111111111111'
'222222222222':
securitygroup: 'sg-2222222222222222'
'333333333333':
securitygroup: 'sg-3333333333333333'
Env2PublicSubnets:
'111111111111':
subnets: subnet-1111111111111111,subnet-22222222222222222,subnet-33333333333333333
'222222222222':
subnets: subnet-1111111111111111,subnet-22222222222222222,subnet-33333333333333333
'333333333333':
subnets: subnet-1111111111111111,subnet-22222222222222222,subnet-33333333333333333
将!Split
与!FindInMap
结合使用以获得列表:
SecurityGroups: !Split [",", !FindInMap [ Env2SecurityGroups, !Ref AWS::AccountId, securitygroup] ]
Subnets: !Split [",", !FindInMap [ Env2PublicSubnets, !Ref AWS::AccountId, subnets] ]
