GKE に kustomize を使ってデプロイしてみる

この記事は Bazel で Go のソースコードをビルドするぞ の延長ですが、 内容がBazel とはあまり関係ない部分なので別記事としました。

上記の記事でも使った以下のリポジトリを使います。

GitHub - righ/bazel-sample-projectContribute to righ/bazel-sample-project development by creating an account on GitHub.https://github.com/righ/bazel-sample-project

今回の記事では Deployment を使った普通のデプロイについては書かないのでご了承ください。

下準備

デプロイするにあたって必要なツールをセットアップしていきます。

GCP のアカウント作成はここでは説明しません。 新規作成の場合は無料枠が3万円分もらえるはずなのでとりあえず作ってみるとよいでしょう。

下準備が大半を占めてるのではよ本題は入れって人は 飛ばしてください

kubectl Installation

この記事の目的である kustomize を使ってデプロイするだけであれば kubectl は必要ありませんが、 色々確認するために使うのでインストールしておきましょう。

Mac や Windows の場合は DockerDesktop をインストールして Kubernetes を有効にすれば OK です。

それ以外の場合は公式ドキュメントを参照してください。 kubectlのインストールおよびセットアップKubernetesのコマンドラインツールであるkubectlを使用して、Kubernetesクラスターに対してコマンドを実行することができます。kubectlによってアプリケーションのデプロイや、クラスターのリソース管理、検査およびログの表示を行うことができます。kubectlの操作に関する完全なリストは、kubectlの概要を参照してください。 始める前に kubectlのバージョンは、クラスターのマイナーバージョンとの差分が1つ以内でなければなりません。たとえば、クライアントがv1.2であれば、v1.1、v1.2、v1.3のマスターで動作するはずです。最新バージョンのkubectlを使うことで、不測の事態を避けることができるでしょう。 Linuxへkubectlをインストールする curlを使用してLinuxへkubectlのバイナリをインストールする 次のコマンドにより、最新リリースをダウンロードしてください: curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl" 特定のバージョンをダウンロードする場合、コマンドの$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)の部分を特定のバージョンに書き換えてください。 たとえば、Linuxへv1.22.0のバージョンをダウンロードするには、次のコマンドを入力します: curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.22.0/bin/linux/amd64/kubectl kubectlバイナリを実行可能にしてください。 chmod +x ./kubectl バイナリをPATHの中に移動させてください。 sudo mv ./kubectl /usr/local/bin/kubectl インストールしたバージョンが最新であることを確認してください: kubectl version --client ネイティブなパッケージマネージャーを使用してインストールする Ubuntu、DebianまたはHypriotOS CentOS、RHELまたはFedora sudo apt-get update && sudo apt-get install -y apt-transport-https gnupg2 curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.https://kubernetes.io/ja/docs/tasks/tools/install-kubectl/

Google Cloud SDK の Setup

GKE にデプロイするには Google Cloud SDK をインストールする必要があります。

環境に合わせてセットアップします。

Mac や Linux の場合は少々面倒で アーカイブをダウンロードしてスクリプトを実行する必要があります。

私の場合はホームディレクトリ配下に解凍して google-cloud-sdk/install.sh を実行しました。 google-cloud-sdk/bin/ 配下にコマンドがあるので PATH を設定すれば gcloud コマンドが使えるようになります。

最後に gcloud init を実行すれば OAuth の認証が行われ、GCPのアカウント(プロジェクト) とひも付きます。

クラスタを作成する

Kubernetes で管理する最も大きな単位が クラスタという入れ物です。

クラスタは GUI で作成することもできますが、コマンドでも作成できます。 今回は gcloud コマンドを使って sample-cluster というクラスタを作りました。

$ gcloud container clusters create --num-nodes=2 sample-cluster \ [master] --zone asia-northeast1-a \ --machine-type g1-small \ --min-nodes=2 --max-nodes=3 WARNING: Currently VPC-native is not the default mode during cluster creation. In the future, this will become the default mode and can be disabled using `--no-enable-ip-alias` flag. Use `--[no-]enable-ip-alias` flag to suppress this warning. WARNING: Newly created clusters and node-pools will have node auto-upgrade enabled by default. This can be disabled using the `--no-enable-autoupgrade` flag. WARNING: Starting in 1.12, default node pools in new clusters will have their legacy Compute Engine instance metadata endpoints disabled by default. To create a cluster with legacy instance metadata endpoints disabled in the default node pool, run `clusters create` with the flag `--metadata disable-legacy-endpoints=true`. WARNING: Your Pod address range (`--cluster-ipv4-cidr`) can accommodate at most 1008 node(s). This will enable the autorepair feature for nodes. Please see https://cloud.google.com/kubernetes-engine/docs/node-auto-repair for more information on node autorepairs. Creating cluster sample-cluster in asia-northeast1-a... Cluster is being health-checked (master is healthy)...done. Created [https://container.googleapis.com/v1/projects/righm9/zones/asia-northeast1-a/clusters/sample-cluster]. To inspect the contents of your cluster, go to: https://console.cloud.google.com/kubernetes/workload_/gcloud/asia-northeast1-a/sample-cluster?project=righm9 kubeconfig entry generated for sample-cluster. NAME LOCATION MASTER_VERSION MASTER_IP MACHINE_TYPE NODE_VERSION NUM_NODES STATUS sample-cluster asia-northeast1-a 1.14.10-gke.27 34.85.37.248 g1-small 1.14.10-gke.27 2 RUNNING

(おそらく)コマンドでの作成が終わると自動的にコンテキストが切り替わります。(少し自信なし) 切り替わっていない場合は kubectl config use-context でスイッチしましょう。

コンテキストとは kubectl が指すクラスタです。

kubectl で確認してみましょう。

$ kubectl config get-contexts [master] CURRENT NAME CLUSTER AUTHINFO NAMESPACE docker-desktop docker-desktop docker-desktop docker-for-desktop docker-desktop docker-desktop * gke_righm9_asia-northeast1-a_sample-cluster gke_righm9_asia-northeast1-a_sample-cluster gke_righm9_asia-northeast1-a_sample-cluster

無事に GKE に作成したクラスタにスイッチされていますね。

この記事では gke_righm9_asia-northeast1-a_sample-cluster コンテキストに スイッチされている前提で話を進めていきます。

warning
  • ローカルの開発でも Kubernetes を使っている場合はコンテキストを戻すことを忘れないようにしましょう。
kubectl config use-context docker-desktop Switched to context "docker-desktop".

GCR に Push する

GKE で利用するイメージはどこかしらの Dockerレジストリに Push する必要があります。

Bazel で Go のソースコードをビルドするぞ で Docker Hub に Push してあったのですが、なぜかそれを指定しても Pull できなかった(ImagePullBackOff)ので おとなしく GCR に Push することにしました。

docker コマンドで gcr に PUSH するために 認証ヘルパー を使います。

$ gcloud auth configure-docker Adding credentials for all GCR repositories. WARNING: A long list of credential helpers may cause delays running 'docker build'. We recommend passing the registry name to configure only the registry you are using. After update, the following will be written to your Docker config file located at [/Users/righ/.docker/config.json]: { "credHelpers": { "gcr.io": "gcloud", "marketplace.gcr.io": "gcloud", "eu.gcr.io": "gcloud", "us.gcr.io": "gcloud", "staging-k8s.gcr.io": "gcloud", "asia.gcr.io": "gcloud" } } Do you want to continue (Y/n)? Y Docker configuration file updated.

無事認証が終わったら 以下のようにタグを付けて Push するのが一般的な方法です。

$ docker build -t gcr.io/プロジェクトID/イメージ名 ビルドコンテキスト $ docker push gcr.io/プロジェクトID/イメージ名
Bazel を使って GCR にPUSHする今回使うリポジトリはもともと Bazel を使うためのサンプルなので GCR へ PUSH するための設定もしてあります。

これを使って Push してみます。

  • $ bazel run //gateway:push_to_gcr INFO: Analyzed target //gateway:push_to_gcr (1 packages loaded, 7 targets configured). INFO: Found 1 target...

INFO: Build completed successfully, 2 total actions INFO: Build completed successfully, 2 total actions 2020/05/03 22:46:55 Successfully pushed Docker image to gcr.io/righm9/echo:latest

こんな感じになっていれば OK です。

kustomize というリポジトリはこの後のセクションで作ります。

kustomize

GKE へのデプロイで kustomize を使うには GoogleCloudPlatform/cloud-builders-community - Github を使います。

Clone して、移動して

$ git clone https://github.com/GoogleCloudPlatform/cloud-builders-community Cloning into 'cloud-builders-community'... remote: Enumerating objects: 3866, done. remote: Total 3866 (delta 0), reused 0 (delta 0), pack-reused 3866 Receiving objects: 100% (3866/3866), 965.20 KiB | 660.00 KiB/s, done. Resolving deltas: 100% (1748/1748), done. $ cd cloud-builders-community/kustomize

以下のように gcloud builds submit でビルドすると kustomize という GCR にリポジトリが作られます。 (順番が前後しますが先程のリポジトリはこれによって作られたものだったのです)

これで kustomize リポジトリができているはずなので確認してみてください。

GKEにDeployする

ようやくここからが本番です。

ここでも gcloud builds submit コマンドを使ってビルドをしていきます。 先程使った cloudbuild.yaml と同じファイル名ですが中身は異なり、前のセクションで作成した kustomize リポジトリを使って production の Kustomization をビルドしています。

これだけです。

ワークロードを見てみると Push されていることがわかりますね。

production の kustomization.yaml では GCR に Push したイメージを使うようにベースの定義にパッチしています。

    最後に gateway の IP にアクセス&動作確認してみます。

    (もうアクセスできません)

    無事動いたのでおしまい。
