Runtime environment variables¶

To run the test suite, some runtime environment variables are to be set.

OCP >=4.12 Labels¶

The following labels need to be added to your default namespace in your cluster if you are running OCP >=4.12:

pod-security.kubernetes.io/enforce: privileged
pod-security.kubernetes.io/enforce-version: latest

You can manually label the namespace with:

oc label namespace/default pod-security.kubernetes.io/enforce=privileged
oc label namespace/default pod-security.kubernetes.io/enforce-version=latest

Disable intrusive tests¶

To skip intrusive tests which may disrupt cluster operations, issue the following:

export TNF_NON_INTRUSIVE_ONLY=true

Likewise, to enable intrusive tests, set the following:

export TNF_NON_INTRUSIVE_ONLY=false

Intrusive tests are enabled by default.

Preflight Integration¶

When running the preflight suite of tests, there are a few environment variables that will need to be set:

PFLT_DOCKERCONFIG is a required variable for running the preflight test suite. This provides credentials to the underlying preflight library for being able to pull/manipulate images and image bundles for testing.

When running as a container, the docker config is mounted to the container via volume mount.

When running as a standalone binary, the environment variables are consumed directly from your local machine.

See more about this variable here.

TNF_ALLOW_PREFLIGHT_INSECURE (default: false) is required set to true if you are running against a private container registry that has self-signed certificates.

Disconnected environment¶

In a disconnected environment, only specific versions of images are mirrored to the local repo. For those environments, the partner pod image quay.io/testnetworkfunction/cnf-test-partner and debug pod image quay.io/testnetworkfunction/debug-partner should be mirrored and TNF_PARTNER_REPO should be set to the local repo, e.g.:

export TNF_PARTNER_REPO=registry.dfwt5g.lab:5000/testnetworkfunction

Note that you can also specify the debug pod image to use with SUPPORT_IMAGE environment variable, default to debug-partner:5.0.8.
