Try to install Kubeflow by following this guide. But when I run

kfctl apply -V -f https://raw.githubusercontent.com/kubeflow/manifests/v0.7-branch/kfdef/kfctl_k8s_istio.0.7.1.yaml

it reports

Usage:
  kfctl apply -f ${CONFIG} [flags]

Flags:
  -f, --file string   Static config file to use. Can be either a local path:
                      		export CONFIG=./kfctl_gcp_iap.yaml
                      	or a URL:
                      		export CONFIG=https://raw.githubusercontent.com/kubeflow/manifests/v0.7-branch/kfdef/kfctl_gcp_iap.0.7.0.yaml
                      		export CONFIG=https://raw.githubusercontent.com/kubeflow/manifests/v0.7-branch/kfdef/kfctl_existing_arrikto.0.7.0.yaml
                      		export CONFIG=https://raw.githubusercontent.com/kubeflow/manifests/v0.7-branch/kfdef/kfctl_aws.0.7.0.yaml

                      	kfctl apply -V --file=${CONFIG}
  -h, --help          help for apply
  -V, --verbose       verbose output default is false

It did cost me some time to find the solution. So let’s try to make it short:

  1. Download file https://raw.githubusercontent.com/kubeflow/manifests/v0.7-branch/kfdef/kfctl_k8s_istio.0.7.1.yaml, and find some of its bottom lines:
  2. - name: manifests
        uri: https://github.com/kubeflow/manifests/archive/v0.7-branch.tar.gz
    
  3. Download the https://github.com/kubeflow/manifests/archive/v0.7-branch.tar.gz, untar it, and then there will be a new directory “manifests-0.7-branch”
  4. Change the “uri:” in kfctl_k8s_istio.0.7.1.yaml to “uri: /full/path/manifests-0.7-branch”

Now, we could run kfctl apply -V -f ${CONFIG_URI} successfully.
Seems although Kubeflow has been developed for almost two years, there are still some basic problem exists in it. A little disappointment to me.
