2.3.5 Setting up Other Network Options

This section contains information on other network related configuration that affects an Oracle Linux Cloud Native Environment deployment. You may not need to make changes from this section, but they are provided to help you understand any issues you may encounter related to network configuration. Internet Access

The Platform CLI checks it is able to access the container registry, and possibly other Internet resources, to be able to pull any required container images. Unless you intend to set up a local registry mirror for container images, the systems where you intend to install Oracle Linux Cloud Native Environment must either have direct internet access, or must be configured to use a proxy.
