Error on install docker-registry to custom namespace

[janfrederik]

Error message when installing docker-registry to a specific namespace, using ark install docker-registry -n myregistry.

Expected Behaviour

The docker registry should be installed in the namespace myregistry.

Current Behaviour

Error message:

Error: to override the "default", install via tiller

Install without specifying a namespace works like a charm.

• What arkade version is this?

Version: 0.8.50
Git Commit: 238a5fc390147e6658bd8d1562f257dfedf88f43

Seems to be by design currently:

arkade/cmd/apps/registry_app.go

Lines 58 to 61 in 405b09a

	namespace, _ := command.Flags().GetString("namespace")
	if namespace != "default" {
	return fmt.Errorf(`to override the "default", install via tiller`)
	}

I see.
But why?
Would be logic to be able to install to a different namespace.

@janfrederik are you willing to send a PR and test it?

[janfrederik]

are you willing to send a PR and test it?
@alexellis Alas, I have no knowledge of Go and no experience with building and testing arkade. I could make a PR leaving out the lines 59-61 that @rgee0 quoted above, but that's all.

I have an eBook on Go that you may find useful, if you want to do the PR, send me an email to alex@openfaas.com for a 50% discount on the premium edition.

You need to clone the code
Change the lines
Run go build
Then test the new arkade binary that was created with a different namespace

Following that, create a fork, sync your changes and send a PR up.
