Getting latest version of the SSM parameter

[farminf]

Version for ParameterStoreStringProps is mandatory and number.

I want to get the latest version of the parameter value.

This is unfortunately not supported by CloudFormation using that construct for it. If you use a Secrets Manager value, you can retrieve the latest version.

However, you may be able to use a Parameter configured for reading values from SSMPS.

Thanks,
Anyway, I got it without specifying version, like this:

const { SSMParameterProvider } = require("@aws-cdk/cdk");

    value = new SSMParameterProvider(this, {
      parameterName: "/xxx/xxx",
    }).parameterValue();

Ah yes, forgot about that one. It does something slightly different: it caches the retrieved value in cdk.json, so be aware of that when you want to update.

Here's an example of how to use a parameter to read the latest version from the SSMPS.

const amiId = new cdk.Parameter(this,
  'AmiId',
  {
    type: 'AWS::SSM::Parameter::Value<String>',
    default: '/ami/sandbox/spark-standalone'
  }).ref;
