ElasticIP | Praxis resources

Resource definition

What this resource looks like

This is the CUE shape a Praxis template uses to declare a ElasticIP. The resource key is local to the template; metadata.name supplies its stable Praxis identity.

resources: {
  natEip: {
  	apiVersion: "praxis.io/alpha"
  	kind:       "ElasticIP"
  	metadata: name: "\(_naming.prefix)-nat-eip"
  	spec: {
  		region: _naming.region
  		domain: "vpc"
  		tags:   #StandardTags
  	}
  }
}

Outputs

Praxis records these values after observation. A dependent resource can read one with ${resources.<name>.outputs.<field>}.

Read without ownership

Data-source lookup

A data block reads an existing ElasticIP and exposes its outputs without storing lifecycle state. The generic filter surface accepts id, name, and tag; supported combinations depend on the AWS identity used by this resource.

data: existing: {
  kind: "ElasticIP"
  region: "us-west-2"
  filter: {
    name: "replace-with-provider-name"
  }
}

Adopt existing infrastructure

Import

Import persists Praxis state for an existing AWS resource. For this kind, supply: Provider identifier for the existing ElasticIP. The example starts in observed mode so Praxis reports drift without correcting it.

praxis import ElasticIP \
  --id <provider-identifier> \
  --region us-west-2 \
  --account production \
  --observe
