# aws-cdk-ssm-sdk-parameter

Thats an AWS CDK Construct for get and set the value of an SSM parameter. It is designed to be loose coupled and be not managed through AWS CDK / Cloudformation so that the SSM parameter can exist across different stacks and be updated without causing a drift. The looseness is reached through using CFN Custom Resources.

The implementation simply leverages [AwsCustomResource](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_custom-resources.AwsCustomResource.html) as an SDK wrapper for:

* https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ssm/get-parameter.html https://docs.aws.amazon.com/systems-manager/latest/APIReference/API_GetParameter.html
* https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ssm/put-parameter.html https://docs.aws.amazon.com/systems-manager/latest/APIReference/API_PutParameter.html
* https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ssm/delete-parameter.html https://docs.aws.amazon.com/systems-manager/latest/APIReference/API_DeleteParameter.html

# Features

* If the parameter doesn't exist, it will be created. Otherwise it pulls the current value of the parameter.
* optional delete when destroying the stack

# Use Case

Initialize a parameter to some value upon creation, but allow it to diverge during future CDK deployments.

SSM StringParameter APP_VERSION of an image is used across ECS deployments. New ECS deployments use that latest version value in it. APP_VERSION isn't managed / editable with CDK but if APP_VERSION wouldn't exist you can specify kind of default.

# Example

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
stack = cdk.Stack(app, "ssm-demo-stack", env=env)

# Create a loose coupled SSM Parameter from type String
SSMParameter(stack, "SSMParameter",
    parameter_name="fooString",
    default_value="fooValue"
)

# Create a loose coupled SSM Parameter from type StringList
SSMParameter(stack, "SSMParameterStringList",
    parameter_name="fooStringList",
    default_value="fooValue1,fooValue2,fooValue3",
    type=SSMParameterType.StringList
)

# Delete the SSM Parameter if the stack gets deleted
SSMParameter(stack, "SSMParameterWithDelete",
    parameter_name="fooWithDelete",
    default_value="fooValue",
    delete=True
)
```

# Local Testing

For local testing simply run

```
yarn deploy --profile X
```

For destroying use

```
yarn destroy --profile X
```

# Limitation

* SSM SecureString Parameter are not supported
* default description are not supported
