Description
Use case
A service invoices depends on another service's stack users, and we to make sure that a supported version of users is deployed when building a local dev stack.
Proposal
Schema
#SemVer: {
prefix: string | *""
major: uint | *0
minor: uint | *0
patch: uint | *0
suffix: string | *""
value: "\(prefix)\(major).\(minor).\(patch)\(suffix)"
}
#Component: {
$metadata: {
id: string
labels: [string]: string
version: #SemVer
}
#Trait
}Service invoices that depends on an imported stack of another service users and want to constrain the supported version
