Managing Secrets

In PoC secenarios all secrets are generated from the data of the values file. In production environments, this is not recommended, since ther should not be any confidential data in the values file. Therefore the Kubernetes secrets have to be created beforhand, manually or ideally from a vault. The Smartfacts and OSLC Adapter charts support the use of pre-installed Kubernetes secrets.

Secret Templates

Most secrets, except the tls secret, are opaque secets. You can use the following template to construct the secrets:

Opaque secrets

apiVersion: v1
data:
  <Secret Field Name 1>: <base64 encoded secret data 1>
  <Secret Field Name 2>: <base64 encoded secret data 2>
  ...
kind: Secret
metadata:
  name: <Name of the secret in Kubernets>
type: Opaque

TLS Secrets

apiVersion: v1
data:
  tls.crt: <Complete certificate chain in PEM format, encoded as base64>
  tls.key: <certificate key in PEM format, encoded as base64>
kind: Secret
metadata:
  name: <Name of the secret in Kubernets>
type: kubernetes.io/tls

Docker config json Secrets

To generate the value to insert in the secret, fill in the "..." placeholder with your username and password for the docker image registry, replace the retistry name “repo.mid.de” with your own registry if needed.

{
  "auths":
  {
    "repo.mid.de" :
    {
      "username":"...",
      "password":"..."
    }
  }
}

Encode the whole json as base64 with padding and insert the base64 string in the secret template:

apiVersion: v1
data:
  .dockerconfigjson: ...
kind: Secret
metadata:
  name: <Name of the secret in Kubernets>
type: kubernetes.io/dockerconfigjson
