使用AWS CloudFormation引用创建yaml

如何解决使用AWS CloudFormation引用创建yaml

我需要一个可以在下面创建yaml代码的python代码。

    Tags:
    - Key: key1
      Value: !Ref 'AWS::StackName'
    - Key: Key2
      Value: !Ref 'AWS::StackId'

这就是我无法解决的问题。

def generate_resource(ami,source_data):
    resource = {
         "Type": "AWS::EC2::Instance","Properties": {
             "ImageId": ami["ImageId"],"InstanceType": ami["InstanceType"],"PrivateIpAddress": ami["PrivateIpAddress"],"KeyName": ami["KeyName"]
             "SubnetId": { "Ref": "SubnetId" },"SecurityGroupIds": { "Ref":  "SecurityGroupId" },"Tags": [
                 { "Key": "key1","Value": "{!Ref 'AWS::StackName'}"},{ "Key": "key2","Value": "{!Ref 'AWS::StackId'}"}
             ]
         }
     }

此代码的yaml输出格式不正确，因此它只是复制{!Ref 'AWS::StackName'}作为值。

import os,sys
import lib.aws as aws,lib.cft as cft,lib.inventory as inventory 

BUCKET_NAME = 'testbucket'


def generate_cft(commit_hash,file_dict,dry_run):
    return (
        "# Autogenerated CFT for commit hash " + commit_hash + "\n" + 
        cft.generate(inventory.read(file_dict["path"]))
    )


def upload_cft(commit_hash,cft_text):
    target_key = commit_hash + "/" + file_dict["name"].split("_")[0] +    ".yaml"

    aws.upload(BUCKET_NAME,target_key,cft_text)


def show_cft(file_dict,cft_text):
    print(file_dict["path"] + " generates the following cft:")
    print("")
    print(cft_text)
    print("")


def generate_and_upload(commit_hash,dry_run):
    cft_text = generate_cft(commit_hash,dry_run)

    aws.validate_cft(cft_text)

    if dry_run: 
        show_cft(file_dict,cft_text)
    else:
        upload_cft(commit_hash,cft_text)


def generate_and_upload_all(commit_hash,dry_run):
    for file_dict in inventory.list():
        print("generating cft for " + file_dict["path"])
        generate_and_upload(commit_hash,dry_run)


if __name__ == "__main__":
    if not os.getcwd().endswith("ci"):
        print("Please run this script from the ci directory")
        exit()

    commit_hash = sys.argv[1] if len(sys.argv) >= 2 else "test"
    generate_and_upload_all(commit_hash,False)

解决方法

是的！！！我试着弄清楚了代码。这是CFT创建期间的语法错误。现在，当我使用生成的CFT创建堆栈时，标记值将替换为实际的“ StackId”。。感谢大家的帮助和指导。

def generate_resource(ami,source_data):
resource = {
    "Type": "AWS::EC2::Instance","Properties": {
        "ImageId": ami["ImageId"],"InstanceType": ami["InstanceType"],"PrivateIpAddress": ami["PrivateIpAddress"],"KeyName": ami["KeyName"],"SubnetId": { "Ref": "SubnetId" },"SecurityGroupIds": { "Ref":  "SecurityGroupId" },"Tags": [
            { "Key": "Name","Value": ami["Name"] },{ "Key": "BootUpDependsOn","Value": ami["BootUpDependsOn"]},{ "Key": "WaitTimeAfterBootUp","Value": ami["WaitTimeAfterBootUp"]},{ "Key": "Key1","Value": { "Ref": "AWS::StackName" }},{ "Key": "Key2","Value": { "Ref": "AWS::StackId" }}
        ]
    }
}
