Summary
Here’s some insight into what’s happening under the covers during the Quick Start tutorial.
The Quick Start guide first installs the WebLogic Kubernetes Operator, then creates a domain using the Model in Image domain home source type.
- For a comparison of Model in Image to other domain home source types, see Choose a domain home source type.
- To learn more about Model in Image domains, see the detailed Model in Image user guide.
- Also recommended, review a detailed Model in Image sample here.
The WebLogic domain configuration is specified using the WebLogic Deployment Tool (WDT) model YAML file in a separate auxiliary image.
- The auxiliary image contains a WebLogic domain and WebLogic application defined by using WDT model YAML and application archive files.
- To learn more about auxiliary images, see the user guide.
- If you want to step through the auxiliary image creation process, follow the instructions in the Advanced do-it-yourself section.
The operator detects the domain and cluster resources, and deploys their WebLogic Server Administration Server and Managed Server pods.

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
The connection to the server localhost:8080 was refused - did you specify the right host or port?

[dave@fedora ~]$ sudo systemctl start docker
[dave@fedora ~]$ sudo docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
