knative のインストール 失敗

どのクラウドでも使えるサーバレス「GitLab Serverless」をGitLabが発表。KubernetesとKnativeがベース
https://www.publickey1.jp/blog/18/gitlab_serverlessgitlabkubernetesknative.html

Knativeをベースにしたサーバレス環境「Pivotal Function Service」、Pivotalがアルファ版発表
https://www.publickey1.jp/blog/18/knativepivotal_function_servicepivotal.html

Knative っすかー。やってみる。まずは1ノード(cpu:2core mem:4gb)で。

Installing Istio

```

```

```
> kubectl label namespace default istio-injection=enabled
namespace "default" labeled
```

Running, Completed になるまで待つ

```

Installing Knative components

ネイティブサービングコンポーネントとビルドコンポーネントのインストール

```
> kubectl apply --filename https://github.com/knative/serving/releases/download/v0.2.2/release.yaml
namespace "knative-build" created
clusterrole.rbac.authorization.k8s.io "knative-build-admin" created
serviceaccount "build-controller" created
clusterrolebinding.rbac.authorization.k8s.io "build-controller-admin" created
customresourcedefinition.apiextensions.k8s.io "builds.build.knative.dev" created
:
clusterrolebinding.rbac.authorization.k8s.io "prometheus-system" created
service "prometheus-system-np" created
statefulset.apps "prometheus-system" created
service "zipkin" created
deployment.apps "zipkin" created
```

kubectl get pods とここで、反応しなくなった。

```
> kubectl get pods --namespace knative-serving
```

rancherがこうなった。

やっぱりテキトーはよくないか

3ノード(cpu:2core mem:4gb) でもダメ。やっぱりテキトーはよくないか
