Chapter 5. Using oc and kubectl commands

You can use the kubectl CLI tool to interact with Kubernetes primitives on your Red Hat build of MicroShift cluster. You can also use existing kubectl workflows and scripts for new Red Hat build of MicroShift users coming from another Kubernetes environment, or for those who prefer to use the kubectl CLI.

The kubectl CLI tool is included in the archive if you download the oc CLI tool.

For more information, read the Kubernetes CLI tool documentation.

The oc CLI tool offers the same capabilities as the kubectl CLI tool, but it extends to natively support additional Red Hat build of MicroShift features, including:

Non-security API changes will involve, at minimum, two minor releases (4.1 to 4.2 to 4.3, for example) to allow older oc binaries to update. Using new capabilities might require newer oc binaries. A 4.3 server might have additional capabilities that a 4.2 oc binary cannot use and a 4.3 oc binary might have additional capabilities that are unsupported by a 4.2 server.

Fully compatible.

oc client might not be able to access server features.

oc client might provide options and features that might not be compatible with the accessed server.
