kubebuilder: etcd should not be assumed to be in /usr/local/kubebuilder/bin/etcd

I installed the Kubebuilder binaries in a personal folder:

/usr/local/home/cflewis/bin/kubebuilder/etcd

Kubebuilder assumes that etcd is in /usr/local/kubebuilder/bin/etcd

$ make test
go generate ./pkg/... ./cmd/...
go fmt ./pkg/... ./cmd/...
go vet ./pkg/... ./cmd/...
go run vendor/sigs.k8s.io/controller-tools/cmd/controller-gen/main.go all

Makefile:9: recipe for target 'test' failed
make: *** [test] Error 1

My grepping found this:

./vendor/sigs.k8s.io/controller-runtime/pkg/envtest/server.go:  defaultEtcdBin          = "/usr/local/kubebuilder/bin/etcd"

As long as etcd is in the user’s path, things should work. Is there a reason a full path was hardcoded?

kubebuilder needs to be unzipped or linked to default directory which is ‘/usr/local/kubebuilder’ as instructed in document. Kubebuilder uses binaries from it

I saw the same error when I ran make test in the workspace created using kubebuiler due to missing /usr/local/kubebuilder/bin/etcd file on the host:

go test ./api/... ./controllers/... -coverprofile cover.out
...
2019-05-22T16:25:21.837Z	ERROR	controller-runtime.test-env	unable to start the controlplane	{"tries": 0, "error": "fork/exec /usr/local/kubebuilder/bin/etcd: no such file or directory"}

The following steps resolved the error for me and then make test worked fine:

wget https://github.com/kubernetes-sigs/kubebuilder/releases/download/v2.0.0-alpha.1/kubebuilder_2.0.0-alpha.1_linux_amd64.tar.gz
tar -zxvf  kubebuilder_2.0.0-alpha.1_linux_amd64.tar.gz
sudo mv kubebuilder_2.0.0-alpha.1_linux_amd64 /usr/local/kubebuilder

$ find /usr/local/kubebuilder
/usr/local/kubebuilder
/usr/local/kubebuilder/bin
/usr/local/kubebuilder/bin/etcd
/usr/local/kubebuilder/bin/kube-apiserver
/usr/local/kubebuilder/bin/kubebuilder
/usr/local/kubebuilder/bin/kubectl

workspace_directory$ make test
go fmt ./...

Please consider adding the information to

export KUBEBUILDER_ASSETS = <path of kubebuilder/bin>

in the kubebuilder book.

You can also set the KUBEBUILDER_ASSETS environment variable, for posterity

We can use setup-envtest tool to download which version of assets we need and use like below:

export KUBEBUILDER_ASSETS=$(setup-envtest use 1.25.0 -p path)

export KUBEBUILDER_ASSETS=<path of kubebuilder/bin>

probably remove the “space” on the both sides of the equal sign will be better

With this commit https://github.com/kubernetes-sigs/controller-runtime/commit/c5e5439a4953c1a2cab7975cab74cedc0dde3da2 (which is included at least in 1.0.5) we can use the envvar KUBEBUILDER_ASSETS to pass the bin-directory explicitly.

export KUBEBUILDER_ASSETS=~/sdk/kubebuilder_1.0.5_linux_amd64/bin/

Worked for me with the getting-started example (Except for struggling because of #359).

Yes, I also find this rather very surprising.

That sounds okay to me, shall we close?
