Parameter Store migration

A tool for migrating Typesafe (HOCON) config files to AWS Parameter Store.

To migrate a file from S3: sbt "run s3 <profile> <bucket> <path> <prefix>"

Or to migrate a local file: sbt "run local <profile> <path> <prefix>"

E.g. run s3 my-aws-account my-config-bucket path/to/file.conf /AppName/Stage/

This will create parameters with paths beginning /AppName/Stage/...

The format used by this tool is compatible with https://github.com/guardian/simple-configuration, which can be used to load config from Parameter Store.

Notes

Lists

Lists are represented in Parameter Store by adding the index to the path, e.g.

akka.loggers = ["akka.event.Logging$DefaultLogger", "akka.event.slf4j.Slf4jLogger"]

becomes:

"akka.loggers.0" -> "akka.event.Logging$DefaultLogger"
"akka.loggers.1" -> "akka.event.slf4j.Slf4jLogger"

This works fine with Typesafe config, e.g. config.getStringList("akka.loggers").

It does however mean this tool will not use Parameter Store's StringList type.

Unsupported list types:

• Lists containing a mix of primitives and objects.
• Nested lists.
