Domain credentials secret

The credentials for the WebLogic domain are kept in a Kubernetes Secret where the name of the secret is specified using webLogicCredentialsSecret in the WebLogic Domain resource. Also, the domain credentials secret must be created in the namespace where the Domain will be running.

Note

For an example of a WebLogic Domain YAML file using webLogicCredentialsSecret, see Container Image Protection .

The samples supplied with the operator use a naming convention that follows the pattern <domainUID>-weblogic-credentials, where <domainUID> is the unique identifier of the domain, for example, domain1-weblogic-credentials.

If the WebLogic domain will be started in domain1-ns and the <domainUID> is domain1, an example of creating a Kubernetes generic secret is as follows:

$ kubectl -n domain1-ns create secret generic domain1-weblogic-credentials \
  --from-file=username --from-file=password
$ kubectl -n domain1-ns label secret domain1-weblogic-credentials \
  weblogic.domainUID=domain1 weblogic.domainName=domain1
Tip

Oracle recommends that you not include unencrypted passwords on command lines. Passwords and other sensitive data can be prompted for or looked up by shell scripts or tooling. For more information about creating Kubernetes Secrets, see the Kubernetes Secrets documentation.

The operator’s introspector job will expect the secret key names to be:

  • username
  • password

For example, here is the result when describing the Kubernetes Secret:

$ kubectl -n domain1-ns describe secret domain1-weblogic-credentials
Name:         domain1-weblogic-credentials
Namespace:    domain1-ns
Labels:       weblogic.domainName=domain1
              weblogic.domainUID=domain1
Annotations:  <none>

Type:  Opaque

Data
====
password:  8 bytes
username:  8 bytes

Domain image pull secret

The WebLogic domain that the operator manages can have images that are protected in the registry. The imagePullSecrets setting on the Domain can be used to specify the Kubernetes Secret that holds the registry credentials.

Info

For more information, see Container Image Protection .

Domain configuration override or runtime update secrets

The operator supports embedding macros within configuration override templates and Model in Image model files that reference Kubernetes Secrets. These Kubernetes Secrets can be created with any name in the namespace where a domain will be running. The Kubernetes Secret names are specified using configuration.secrets in the WebLogic Domain resource.

Info

For more information, see Configuration overrides and Runtime updates .

Operator image pull secret

The Helm chart for installing the operator has an imagePullSecrets option to specify the image pull secret used for the operator’s image when using a private registry; alternatively, the image pull secret can be specified on the operator’s service account.

Info

For more information, see Customizing operator image name, pull secret, and private registry .

Operator external REST interface secret

The operator can expose an external REST HTTPS interface which can be accessed from outside the Kubernetes cluster. A Kubernetes tls secret is used to hold the certificates and private key.

Info

For more information, see REST Services .

Operator internal REST interface secret

The operator exposes an internal REST HTTPS interface with a self-signed certificate. The certificate is kept in a Kubernetes ConfigMap with the name weblogic-operator-cm using the key internalOperatorCert. The private key is kept in a Kubernetes Secret with the name weblogic-operator-secrets using the key internalOperatorKey. These Kubernetes objects are managed by the operator’s Helm chart and are part of the namespace where the operator is installed.

For example, to see all the operator’s ConfigMaps and secrets when installed into the Kubernetes Namespace weblogic-operator-ns, use:

$ kubectl -n weblogic-operator-ns get cm,secret
