Load encrypted data

CUE input file:

package kube

secret: [ID=_]: {
    apiVersion: "v1"
    kind:       "Secret"
    metadata: name: ID
    type: string | *"Opaque"
    data: {[string]: bytes}
}

secret: "tls": {
    type: "kubernetes.io/tls"
    data: {} @readmap(tls)
}

values: {} @read(secret-values.yaml)

secret: "auth": {
    data: {
        DSN:        'postgresql://\(data.DB_USER):\(data.DB_PASS)@dbhost:5432'
        AUTH_TOKEN: '\(values.app."auth-token")'
    } @readmap(auth.env)
}

objects: [ for v in secret {v}]

SOPS-encrypted plain files or structured data (YAML, JSON, .env) can be imported into CUE values or structs. It can be used like any regular CUE value. secretDataPath: secret.*.data needs to be set in cuegen.yaml. Otherwise data in secrets would not be loaded as bytes. Values in secrets.*.data have to be quoted using ', otherwise they would be handled as string.

• @readmap(tls) imports encrypted key and certificate into secret tls
• @readmap(auth.env) reads encrypted .env data into secret auth
• @read(secret-values.yaml) reads encrypted structured multi-level data

YAML output:

apiVersion: v1
kind: Secret
metadata:
name: tls
type: kubernetes.io/tls
data:
  tls.crt: |-
    LS0tLS1CRUdJTiBDRVJUSUZJQ0FUR...UVORCBDRVJUSUZJQ0FURS0tLS0t
  tls.key: |-
    LS0tLS1CRUdJTiBQUklWQVRFIEtFW...kQgUFJJVkFURSBLRVktLS0tLQo=
---
apiVersion: v1
kind: Secret
metadata:
name: auth
type: Opaque
data:
  DSN: cG9zdGdyZXNxbDovL2FkbWluOjUzY3IzdEBkYmhvc3Q6NTQzMg==
  DB_USER: YWRtaW4=
  DB_PASS: NTNjcjN0
  AUTH_TOKEN: c21obHJrdjYtZW50ODJoeGQtdG41NnVwb2ctdnppbG1wdmctaHdxdzQ3dTk=

To run this example you need to set

SOPS_AGE_KEY=AGE-SECRET-KEY-14QUHLE5A6UNSKNYXLF5ZA26P3NCFX8P68JQ066T7VJ6JW5G8FHWQN4HAUQ

in the environment. (what is age?)
