Customizing SSM Parameters

You can customize the SSM parameter names that SST creates behind the scenes to power Resource Binding.

Setting the SSM name prefix​

To provide a prefix, open up the sst.config.ts and add a ssmPrefix field.

sst.config.ts
export default {
  config(input) {
    return {
      name: "myapp",
      region: "us-east-1",
      ssmPrefix: "/myOrg/myTeam/",
    };
  },
  stacks(app) {},
} satisfies SSTConfig;

For example, the default SSM parameter name that's created for a Bucket is:

/sst/my-sst-app/dev/Bucket/myBucket/bucketName

With the ssmPrefix specified, the SSM parameter name will be:

/myOrg/myTeam/Bucket/myBucket/bucketName
