apt update
apt install -y docker-ce docker-ce-cli containerd.ioDagger インストール
mkdir -p /opt/dagger
cd /opt/dagger
curl -L https://dl.dagger.io/dagger/install.sh | sh
export PATH=$PATH:/opt/dagger/bin
echo "export PATH=$PATH:/opt/dagger/bin" >> ~/.bashrc動作確認
Getting Started のサンプルを実行
詳細は CI/CD in your local dev を参照のこと。
apt install -y git
cd ~
git clone https://github.com/dagger/dagger
cd dagger
git checkout v0.2.4
cd pkg/universe.dagger.io/examples/todoapp
dagger do build_build に成果物が生成される。
ゼロからプロジェクトを作る
dagger プロジェクトの初期化
dagger project initプラン作成
firststep.cue を作成する。
`echo “hello, world!” を実行するプラン(とアクション)を作成。
package main
import (
"dagger.io/dagger"
"dagger.io/dagger/core"
)
dagger.#Plan & {
actions: {
_dockerImage: core.#Pull & {source: "alpine:3"}
hello: core.#Exec & {
input: _dockerImage.output
args: ["echo", "hello, world!"]
always: true
}
}
}プロジェクトアップデート
これで利用するモジュールの依存関係を解決するらしい。
dagger project updateプラン実行
root@f32697b02b38:/work/firststep# dagger do hello --log-format=plain
11:10AM INF actions._dockerImage | computing
11:10AM INF actions._dockerImage | completed duration=1.9s
11:10AM INF actions.hello | computing
11:10AM INF actions.hello | completed duration=200ms
11:10AM INF actions.hello | #3 0.153 hello, world!hello, world! が表示されている、 OK.
既存 Ruby プロジェクトのテストをやってみる
rubyTest.cue を作成。
package main
import (
"dagger.io/dagger"
"dagger.io/dagger/core"
)
dagger.#Plan & {
actions: {
// ruby コンテナを利用するので Pull
_dockerImage: core.#Pull & {source: "ruby:2"}
// Git からコードを取得
fetch: core.#GitPull & {
remote: "https://github.com/mikoto2000/binp.git"
ref: "master"
}
_appSource: fetch.output
// Docker 用マウントオプションを定義
_sourceMounts: {
"app source": {
type: "fs"
dest: _workDir
contents: _appSource
}
}
// Docker コンテナを使って依存解決とテスト
_workDir: "/src"
dep: core.#Exec & {
// Pull したコンテナのファイルシステムを使う
input: _dockerImage.output
// ソースコードをマウント
mounts: _sourceMounts
// マウントした場所をワークディレクトリとする
workdir: _workDir
// bundle を使って依存 gem を取得
args: ["bundle", "install"]
// 毎回実行する
always: true
}
build: core.#Exec & {
// dep の実行結果のファイルシステムを継続して使う
input: dep.output
// ソースコードをマウント
mounts: _sourceMounts
// マウントした場所をワークディレクトリとする
workdir: _workDir
// bundle を使ってテスト実行
args: ["bundle", "exec", "rake", "test"]
// 毎回実行する
always: true
}
}
}これを実行すると、以下のようになる。(プロジェクト初期化・更新は省略)
