Files in this directory contain template strings that are used to generate SSM parameter names and values.
You can pass a different directory to pubsys to use a different set of parameters.
The directory is expected to contain a file named defaults.toml with a table entry per parameter, like this:
[[parameter]]
name = "{variant}/{arch}/{image_version}/image_id"
value = "{image_id}"The name and value can contain template variables that will be replaced with information from the current build and from the AMI registered from that build.
The available variables include:
variant, for example "aws-ecs-1"arch, for example "x86_64" or "arm64".- Note: "amd64" and "aarch64" are mapped to "x86_64" and "arm64", respectively, to match the names used by EC2.
image_id, for example "ami-0123456789abcdef0"image_name, for example "bottlerocket-aws-ecs-1-x86_64-v0.5.0-e0ddf1b"image_version, for example "0.5.0-e0ddf1b"region, for example "us-west-2"
You can also list parameters that only apply to specific variants or architectures.
To do so, add variant or arch keys (or both) to your parameter definition.
The parameter will only be populated if the current variant or arch matches one of the values in the list.
(If both variant and arch are listed, the build must match an entry from both lists.)
For example, to add an extra parameter that's only set for "aarch64" builds of the "aws-ecs-1" variant:
[[parameter]]
arch = ["aarch64"]
variant = ["aws-ecs-1"]
name = "/a/special/aarch64/ecs/parameter"
value = "{image_name}"
