Examples with Service io.fabric8.knative.serving.v1.Service used on opensource projects

Example 1 with Service

use of io.fabric8.knative.serving.v1.Service in project che by eclipse.

the class OpenShiftConnector method createContainer.

/**
     * @param createContainerParams
     * @return
     * @throws IOException

    // OpenShiftConnector API methods, but is not acceptable as an OpenShift name

    // in OpenShift
