Create a domain

  1. For use in the following steps:

    • Select a user name and password, following the required rules for password creation (at least 8 alphanumeric characters with at least one number or special character).
    • Pick or create a directory to which you can write output.
  2. Create a Kubernetes Secret for the WebLogic domain administrator credentials containing the username and password for the domain, using the create-weblogic-credentials script:

    $ kubernetes/samples/scripts/create-weblogic-domain-credentials/ \
      -u <username> -p <password> -n sample-domain1-ns -d sample-domain1

    The sample will create a secret named domainUID-weblogic-credentials where the domainUID is replaced with the value specified by the -d flag. For example, the command above would create a secret named sample-domain1-weblogic-credentials.

  3. Create a new image with a domain home by running the create-domain script. First, copy the sample create-domain-inputs.yaml file and update your copy with:

    • domainUID: sample-domain1
    • image: Leave empty unless you need to tag the new image that the script builds to a different name. For example if you are using a remote cluster that will need to pull the image from a container registry, then you should set this value to the fully qualified image name. Note that you will need to push the image manually.
    • weblogicCredentialsSecretName: sample-domain1-weblogic-credentials
    • namespace: sample-domain1-ns
    • domainHomeImageBase:

    For example, assuming you named your copy my-inputs.yaml:

    $ cd kubernetes/samples/scripts/create-weblogic-domain/domain-home-in-image
    $ ./ -i my-inputs.yaml -o /<your output directory> -u <username> -p <password> -e

    You need to provide the same WebLogic domain administrator user name and password in the -u and -p options respectively, as you provided when creating the Kubernetes Secret in Step 2.

  4. Confirm that the operator started the servers for the domain:

    a. Use kubectl to show that the Domain was created:

    $ kubectl describe domain sample-domain1 -n sample-domain1-ns

    b. After a short time, you will see the Administration Server and Managed Servers running.

    $ kubectl get pods -n sample-domain1-ns

    c. You should also see all the Kubernetes Services for the domain.

    $ kubectl get services -n sample-domain1-ns
  5. Create an ingress for the domain, in the domain namespace, by using the sample Helm chart:

    $ helm install sample-domain1-ingress kubernetes/samples/charts/ingress-per-domain \
      --namespace sample-domain1-ns \
      --set wlsDomain.domainUID=sample-domain1 \
  6. To confirm that the ingress controller noticed the new ingress and is successfully routing to the domain’s server pods, you can send a request to the URL for the “WebLogic ReadyApp framework”, as shown in the example below, which will return an HTTP 200 status code.

    $ curl -v -H 'host:' http://localhost:30305/weblogic/ready
      About to connect() to localhost port 30305 (#0)
        Connected to localhost ( port 30305 (#0)
    > GET /weblogic/ HTTP/1.1
    > User-Agent: curl/7.29.0
    > Accept: */*
    > host:
    < HTTP/1.1 200 OK
    < Content-Length: 0
    < Date: Thu, 20 Dec 2018 14:52:22 GMT
    < Vary: Accept-Encoding
    <   Connection #0 to host localhost left intact

    Depending on where your Kubernetes cluster is running, you may need to open firewall ports or update security lists to allow ingress to this port.

  7. To access the WebLogic Server Administration Console:

    a. Edit the my-inputs.yaml file (assuming that you named your copy my-inputs.yaml) to set exposedAdminNodePort: true.

    b. Open a browser to http://localhost:30701.

    Do not use the WebLogic Server Administration Console to start or stop servers. See Starting and stopping servers.
