OpenShift Client - oc

With OpenShift Client CLI (oc), you can create applications and manage OpenShift resources. It is built on top of kubectl which means it provides its full capabilities to connect with any kubernetes compliant cluster, and on top adds commands simplifying interaction with an OpenShift cluster.


All contributions are welcome - oc uses the Apache 2 license and does not require any contributor agreement to submit patches. Please open issues for any bugs or problems you encounter, ask questions on the OpenShift IRC channel (#openshift-dev on freenode), or get involved in the kubectl and kubernetes project at the container runtime layer.


To build oc invoke make oc. At any time you can invoke make help and you'll get a list of all supported make sub-commands.

In order to build oc, you will need the GSSAPI sources. On a Fedora/CentOS/RHEL workstation, install them with:

dnf install krb5-devel


dnf install gpgme-devel
dnf install libassuan-devel

For MacOS you'll need to install a few brew packages before building locally. Install them with:

brew install heimdal
brew install gpgme


All PRs will have to pass a series of automated tests starting from go tools such as go fmt and go vet, through unit tests, up to e2e against a real cluster.

Locally you can invoke the initial verification and unit test through make verify and make test, accordingly.


Dependencies are managed through Go Modules. When updating any dependency the suggested workflow is:

  1. go mod tidy
  2. go mod vendor
