はじめに
前回の例では、GitHub上に管理されたDockerfileを元にOpenShift上でDockerイメージをビルドし、デプロイを行いました。
今回はs2i(source to image)ビルドという方法を用いてOpenShift上にコンテナをデプロイします。
今回の方法はプログラムのソースおよび、ビルダー・イメージと呼ばれる特殊なDockerイメージを用意しておき、それらを元に新たなイメージをビルドし、デプロイする、という流れになります。
今回のシナリオ: ソース + ビルダー・イメージ => OpenShift上のPodとしてデプロイ

全体像
s2iビルド補足
スクリプト言語の場合、アプリケーションのソースを開発して適切なディレクトリにそれらを配置すれば動かせるので、稼働環境を構築するのは比較的楽に行えます。
しかし、C/C++、Java、Go、COBOLなどの言語はコンパイラ言語であるため、基本的に事前にコンパイルを行って実行モジュールを作成するというステップが必要になります。さらにLibertyなどのミドルウェアが絡む場合は関連する定義が必要になるなど、稼働環境を整えるのに複雑な処理が関わってくることになります。
そのような複雑な制御をDockerfileだけで行うのは困難です。OpenShiftではs2iビルドという仕組みを提供しておりソースからアプリケーション稼働環境としてのイメージをビルドするステップを自動化する仕組みを提供してくれています。そこで使われるのが特殊な作法で作られた"ビルダー・イメージ"と呼ばれるDockerイメージです。
CやJavaなどのコンパイラ言語のビルドに必要な開発環境やビルド用のスクリプトを決まった作法でDockerイメージとして作成しておくと、そのビルダー・イメージとソースを与えれば、あとは自動的にビルド、デプロイが行われる、という仕組みです。
Javaなどのよく利用される言語については既にビルダー・イメージが提供されているのでそれをそのまま利用することもできますし、独自にカスタマイズしたビルダー・イメージを用意してそれを使うこともできます。
今回はビルダー・イメージの作成も含めてやってみます。ビルダー・イメージを作成する際は、source-to-image toolkitというツールが利用できます。
GitHub: openshift/source-to-image
※先の例ではGo言語を事前コンパイル無しでgo runコマンドでスクリプト言語のように実行していましたが、実際には裏ではコンパイル(go build相当)が行われて実行モジュールが作成されてそれが実行される、という動きになっています。今回のシナリオでは先のGo言語の例を、コンパイルと実行をきちんと分けてs2iビルドの作法でデプロイしてみます。
s2iビルドで行われる内部処理の流れをざっくりと図で表すと以下のようになります。
このような処理が自動で行われるので、開発環境およびassemble, run スクリプトを仕込んだビルダー・イメージを用意しておけば、ソースを作成/変更～デプロイまでの作業を容易に/迅速に行うことができます。
事前準備
ソースの準備
これまでと同じGo言語のソースを使います。
main.go
package main
import (
"fmt"
"log"
"net/http"
)
func main(){
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request){
log.Println("received request")
fmt.Fprintf(w, "Hello Docker!")
})
log.Println("start server")
server := &http.Server{Addr: ":8080"}
if err := server.ListenAndServe(); err != nil {
log.Println(err)
}
}
ビルダー・イメージの準備
上のGo言語をビルドするためのビルダー・イメージを作成していきます。全体像の図中(3)～(6)に相当する操作です。
何をやっているのか分からなくなりそうなので、ここで実施する操作をもう少し詳細化した図を以下に整理しておきます。
source-to-image toolkitのインストール
作業用のLinuxにsource-to-image toolkitをインストールします。手順は以下のInstallationの箇所を参照。

assemble(original)
assenble
#!/bin/bash -e
#
# S2I assemble script for the 'gobuilder' image.
# The 'assemble' script builds your application source so that it is ready to run.
#
# For more information refer to the documentation:

#
# If the 'gobuilder' assemble script is executed with the '-h' flag, print the usage.
if [[ "$1" == "-h" ]]; then
exec /usr/libexec/s2i/usage
fi
# Restore artifacts from the previous build (if they exist).
#
if [ "$(ls /tmp/artifacts/ 2>/dev/null)" ]; then
echo "---> Restoring build artifacts..."
shopt -s dotglob
mv /tmp/artifacts/* ./
shopt -u dotglob
fi
echo "---> Installing application source..."
cp -Rf /tmp/src/. ./
echo "---> Building application from source..."
# TODO: Add build steps for your application, eg npm install, bundle install, pip install, etc.
assmbleはビルドを行うためのスクリプトです。/tmp/src/以下にソースがコピーされている前提で、そのソースをビルドするための処理をbashで記述します。
ここでは以下のように編集します。
assemble
#!/bin/bash -e
#
# S2I assemble script for the 'gobuilder' image.
# The 'assemble' script builds your application source so that it is ready to run.
#
# For more information refer to the documentation:

#
# If the 'gobuilder' assemble script is executed with the '-h' flag, print the usage.
if [[ "$1" == "-h" ]]; then
exec /usr/libexec/s2i/usage
fi
# Restore artifacts from the previous build (if they exist).
#
#if [ "$(ls /tmp/artifacts/ 2>/dev/null)" ]; then
# echo "---> Restoring build artifacts..."
# shopt -s dotglob
# mv /tmp/artifacts/* ./

#fi
echo "---> Installing application source..."
cp -Rf /tmp/src/. /go/test/
echo "---> Building application from source..."
# TODO: Add build steps for your application, eg npm install, bundle install, pip install, etc.
cd /go/test
export GOCACHE=/go/test;go build main.go
※今回は単純にmain.goというソースがある前提でそれをコンパイルするスクリプトを書いてしまっていますが、本来であればもっと汎用的に任意のソースが配置された場合でもビルドできるようなロジックにしておくことが望ましいと思われます。
run編集
生成されたrunを確認します。
run(original)
run
#!/bin/bash -e
#
# S2I run script for the 'gobuilder' image.
# The run script executes the server that runs your application.
#
# For more information see the documentation:
# https://github.com/openshift/source-to-image/blob/master/docs/builder_image.md
#
exec asdf -p 8080
runはコンテナが稼働する際に実行される処理を記載します(DockerfileのCMDで指定されるイメージ)。
ここでは以下のように編集します。
run
#!/bin/bash -e
#
# S2I run script for the 'gobuilder' image.
# The run script executes the server that runs your application.
#
# For more information see the documentation:

usage編集
生成されたusageを確認します。
usage(original)
usage
#!/bin/bash -e
cat <<EOF
This is the gobuilder S2I image:
To use it, install S2I: https://github.com/openshift/source-to-image
Sample invocation:
s2i build <source code path/URL> gobuilder <application image>
You can then run the resulting image via:
docker run <application image>
EOF
usageにはビルダー・イメージのusageを記述するだけなので用途に合わせて適宜修正します。ここではそのまま。

ローカルでのビルダー・イメージ/ソースのテスト
さて、ビルダー・イメージとソースが準備できましたが、これがきちんと動作するかローカルのLinux環境でテストしておきます。
s2i toolkitではこのビルダー・イメージのテストもできます。つまり、本来OpenShift上で実施されるビルド処理を、ローカルの環境で疑似的にテストできるということです。
適当なディレクトリにapp/main.go(Goのソース)を配置し、出力用のディレクトリgotempを作成しておきます。
[root@Test05 ~/openshift/test/s2i_test]# ls -la app
合計 4
drwxr-xr-x. 2 root root 21 7月 22 17:32 .
drwxr-xr-x. 5 root root 48 7月 22 18:43 ..
-rw-r--r--. 1 root root 453 7月 22 17:32 main.go
[root@Test05 ~/openshift/test/s2i_test]# mkdir gotemp
s2i toolkitの s2i buildコマンドを使用すると、ソースとビルダー・イメージから目的のイメージを生成させることができます。
基本的なsyntaxとしてはこんな感じです。
s2i build <source_dir> <builder_image> <generated_image>
デフォルトだとdocker環境にイメージを生成しようとするようですが、今回はpodman使っているので、一旦Dockerfileとしてイメージを生成させるために--as-dockerfileオプションで出力先ディレクトリを指定します。
[root@Test05 ~/openshift/test/s2i_test]# s2i build app/ gobuilder:latest gotemp --as-dockerfile gotemp/Dockerfile
Application dockerfile generated in gotemp/Dockerfile
[root@Test05 ~/openshift/test/s2i_test]# tree --charset=C gotemp
gotemp
|-- Dockerfile
|-- downloads
| |-- defaultScripts
| `-- scripts
`-- upload
|-- scripts
`-- src
`-- main.go
6 directories, 2 files
これでs2iビルドが疑似的に行われてソースとビルダー・イメージから新たにDockerイメージ(gotemp)が作成されました。
これがちゃんと動くか試してみます。

アクセスできました！ すなわち、先に作ったビルダー・イメージとソースがきちんと意図した通りに動いていることが確認できました。
ビルダー・イメージ/ソースの配置
ビルダー・イメージとソースが問題なさそうなことをローカルで確認できたので、これらをOpenShiftから参照できる所に配置します。
ビルダー・イメージをQuay.ioに配置
ビルダー・イメージは直接OpenShift内の内部レジストリに配置してもよいのですが、ここでは外部のレジストリサービス(Quay.io)を使ってみます。

ブラウザからも参照できる状態になりました。
ソースをGitHub上に配置
先に作ったopenshift-testというリポジトリに別のフォルダ"gotest_s2i_src"というフォルダを用意し、そこにGoのソース(main.go)を配置しておきます。
(通常のgitの操作なのでここでは手順の詳細は省略)
コンテナのデプロイ
上で準備したビルダー・イメージとソースを元に、s2iビルド、デプロイを実施してみます。全体像の図の(7)～(10)を実行します。
プロジェクト作成
# oc new-project tomotag-test03
Now using project "tomotag-test03" on server "https://c100-e.jp-tok.containers.cloud.ibm.com:30549".
You can add applications to this project with the 'new-app' command. For example, try:
oc new-app rails-postgresql-example
to build a new example application in Ruby. Or use kubectl to deploy a simple Kubernetes application:
kubectl create deployment hello-node --image=k8s.gcr.io/serve_hostname
GitHubアクセス用シークレット作成
前回の記事と同じ要領でGitHubアクセス用シークレットを作成します。
参考: OpneShift Container Platform V4.5 - ビルド - 3.4 Gitソース
Basic認証用にユーザーIDとパスワードをLiteralで指定。
# oc create secret generic github --from-literal=username=tomotagwork --from-literal=password=xxxxx --type=kubernetes.io/basic-auth

アノテーションを付与する。
# oc annotate secret github 'build.openshift.io/source-secret-match-uri-1=https://github.com/tomotagwork/*'

ビルダー・イメージのImageStream作成
今回は外部のレジストリ上にあるビルダー・イメージを使用することを想定しているため、oc import-image コマンドを使用して事前にこのビルダー・イメージを参照するImageStreamを作成しておきます。
※oc import-imageコマンドで外部のレジストリにアクセスする際は、現在のプロジェクト内のシークレットを検索し、レジストリーのホスト名と一致するものを探して一致するものを使用してくれるようです。

ビルド&デプロイ
デフォルトではビルド時には"builder"というサービスアカウントが使用されます。ビルドする際に元になるDockerイメージのレジストリに対して認証情報が必要な場合は、"builder"アカウントに対して先に作成したsecretをリンクしておく必要があります。
# oc secrets link builder quayio
これで一通り準備は整ったので、いよいよoc new-appコマンドでコンテナをデプロイします。
syntaxとしては以下のような感じです。
oc new-app --as-deployment-config --name appName --strategy=source builderImage~sourceRepository --context-dir sourceFolder
builderImage: ここでは上で作成した イメージ・ストリーム gobuilder:latest を指定します。
sourceRepository: ここではGitHub上に用意したリポジトリのmainブランチを指定します。(https://github.com/tomotagwork/openshift-test#main)
sourceFolder: ここではターゲットのソースが配置されたGitHubリポジトリ上のフォルダ gotest_s2i_src を指定します。
[root@Test05 ~]# oc new-app --as-deployment-config --name gotest --strategy=source gobuilder:latest~https://github.com/tomotagwork/openshift-test#main --context-dir gotest_s2i_src
--> Found image 3d71b80 (17 hours old) in image stream "tomotag-test03/gobuilder" under tag "latest" for "gobuilder:latest"

* A source build using source code from https://github.com/tomotagwork/openshift-test#main will be created
* The resulting image will be pushed to image stream tag "gotest:latest"
* Use 'oc start-build' to trigger a new build
* This image will be deployed in deployment config "gotest"
* Port 8080/tcp will be load balanced by service "gotest"
* Other containers can access this service through the hostname "gotest"

おわりに
ここでは基本的なフローのみを確認していますが、assembleなどのスクリプトをoc new-app時に置き換えたり(カスタムs2iスクリプト)、ビルド後に簡易的なテストをしてNGだった場合にデプロイを取りやめる処理を組み込んだり(post-commitビルドフック)するなど、他にも拡張機能があるようです。なかなか奥が深い...
