Dammit to proxy
本当によくあるプロキシ問題
Mavenを用いてBuildしようとするとプロキシに弾かれる
でもMavenのCLI用プロキシオプションみたいなのは見つからない
そんなこんなでハマりまくったのでメモ
※Dockerド素人なので注意
背景
Mavenのプロキシ設定はsettings.ymlで設定する
そんなことはどこかしこで見つかる
一応参考はこちら
んなことわかってる！どうやってDockerfileで定義するんや！という話です
ハマったケース
これはscooldが公開しているDockerfileでプロキシ設定がない状態
FROM openjdk:8-jdk-alpine
RUN apk --update add git openssh maven && \
rm -rf /var/lib/apt/lists/* && \
rm /var/cache/apk/*
ENV BOOT_SLEEP=0 \
JAVA_OPTS=""
RUN addgroup -S scoold && adduser -S -G scoold scoold && \
mkdir -p /scoold/clone && \
chown -R scoold:scoold /scoold
USER scoold
WORKDIR /scoold
RUN git clone --depth=1 https://github.com/Erudika/scoold /scoold/clone && \
cd /scoold/clone && \
mvn -DskipTests=true clean package && \
mv target/scoold-*.jar /scoold/ && \
cd /scoold && rm -rf /scoold/clone && rm -rf ~/.m2
EXPOSE 8000
CMD sleep $BOOT_SLEEP && \
java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar scoold-*.jar
apk --updateのプロキシ設定
まずはapk --updateが通らない
これは環境変数さえ定義してあげればいける
ここを参考にどうぞ
FROM openjdk:8-jdk-alpine
ENV http_proxy http://proxy:port
ENV https_proxy http://proxy:port
RUN apk --update add git openssh maven && \
rm -rf /var/lib/apt/lists/* && \
rm /var/cache/apk/*
ENV BOOT_SLEEP=0 \
JAVA_OPTS=""
RUN addgroup -S scoold && adduser -S -G scoold scoold && \
mkdir -p /scoold/clone && \
chown -R scoold:scoold /scoold
USER scoold
WORKDIR /scoold
RUN git clone --depth=1 https://github.com/Erudika/scoold /scoold/clone && \
cd /scoold/clone && \
mvn -DskipTests=true clean package && \
mv target/scoold-*.jar /scoold/ && \
cd /scoold && rm -rf /scoold/clone && rm -rf ~/.m2
EXPOSE 8000
CMD sleep $BOOT_SLEEP && \
java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar scoold-*.jar
もちろん、実行環境の環境変数を参照しても良い（というかその方が間違いがない）けどわかりやすくURLで
ユーザーアカウントとかパスワードとかある場合のURLは色々ググれば出る
まぁこのへんとか
現環境だとENVを連打してもBuildは遅くならないので気にせず二行書く
gitのプロキシ設定
mavenは後回しにして先にgitのプロキシ設定
こっちは情報が山程あるので楽
FROM openjdk:8-jdk-alpine
ENV http_proxy http://proxy:port
ENV https_proxy http://proxy:port
RUN apk --update add git openssh maven && \
rm -rf /var/lib/apt/lists/* && \
rm /var/cache/apk/*
ENV BOOT_SLEEP=0 \
JAVA_OPTS=""
RUN addgroup -S scoold && adduser -S -G scoold scoold && \
mkdir -p /scoold/clone && \
chown -R scoold:scoold /scoold
USER scoold
WORKDIR /scoold
RUN git config --global http.proxy http://proxy:port && \
git config --global https.proxy http://proxy:port && \
git clone --depth=1 https://github.com/Erudika/scoold /scoold/clone && \
cd /scoold/clone && \
mvn -DskipTests=true clean package && \
mv target/scoold-*.jar /scoold/ && \
cd /scoold && rm -rf /scoold/clone && rm -rf ~/.m2
EXPOSE 8000
CMD sleep $BOOT_SLEEP && \
java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar scoold-*.jar
git configを叩くだけ
--globalが指す範囲はこのコンテナだけ...かなぁ
Mavenのプロキシ設定
いよいよ本番
やり方を先に書くと、settings.xmlを探し出して上書き！
・・・絶対もっといい方法あるはずなんで誰か教えてくだしあ
まずはsettings.xmlのありかを探す
FROM openjdk:8-jdk-alpine
ENV http_proxy http://proxy:port
ENV https_proxy http://proxy:port
RUN apk --update add git openssh maven && \
rm -rf /var/lib/apt/lists/* && \
rm /var/cache/apk/*
RUN find / -name settings.xml
結果はこんな感じ
Step 3/3 : RUN find / -name settings.xml
---> Running in 665a8bbce0e9
/usr/share/java/maven-3/conf/settings.xml
なるほど、こげなとこにおるんかという感想
Dockerfileからいじりにいってもいいんだろうけど、書くのが面倒だったし上書きしてしまおう！
...ちょっと不安なので中身をチェック
FROM openjdk:8-jdk-alpine
ENV http_proxy http://proxy:port
ENV https_proxy http://proxy:port
RUN apk --update add git openssh maven && \
rm -rf /var/lib/apt/lists/* && \
rm /var/cache/apk/*
RUN cat /usr/share/java/maven-3/conf/settings.xml
結果はこんな感じ
Step 3/3 : RUN cat /usr/share/java/maven-3/conf/settings.xml
---> Running in 0bf28b7a5d98

<!-- mirrors
| This is a list of mirrors to be used in downloading artifacts from remote repositories.
|
| It works like this: a POM may declare a repository to use in resolving certain artifacts.
| However, this repository may have problems with heavy traffic at times, so people have mirrored
| it to several places.
|
| That repository definition will have a unique id, so we can create a mirror reference for that
| repository, to be used as an alternate download site. The mirror site will be the preferred
| server for that repository.
|-->
<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
|
<mirror>
<id>mirrorId</id>
<mirrorOf>repositoryId</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>http://my.repository.com/repo/path</url>
</mirror>
-->
</mirrors>
<!-- profiles
| This is a list of profiles which can be activated in a variety of ways, and which can modify
| the build process. Profiles provided in the settings.xml are intended to provide local machine-
| specific paths and repository locations which allow the build to work in the local environment.
|
| For example, if you have an integration testing plugin - like cactus - that needs to know where
| your Tomcat instance is installed, you can provide a variable here such that the variable is
| dereferenced during the build process to configure the cactus plugin.
|
| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
| section of this document (settings.xml) - will be discussed later. Another way essentially
| relies on the detection of a system property, either matching a particular value for the property,
| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
| value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
| Finally, the list of active profiles can be specified directly from the command line.
|
| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
| repositories, plugin repositories, and free-form properties to be used as configuration
| variables for plugins in the POM.
|
|-->
<profiles>
<!-- profile
| Specifies a set of introductions to the build process, to be activated using one or more of the
| mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
| or the command line, profiles have to have an ID that is unique.
|
| An encouraged best practice for profile identification is to use a consistent naming convention
| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
| This will make it more intuitive to understand what the set of introduced profiles is attempting
| to accomplish, particularly when you only have a list of profile id's for debug.
|
| This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
<profile>
<id>jdk-1.4</id>
<activation>
<jdk>1.4</jdk>
</activation>
<repositories>
<repository>
<id>jdk14</id>
<name>Repository for JDK 1.4 builds</name>
<url>http://www.myhost.com/maven/jdk14</url>
<layout>default</layout>
<snapshotPolicy>always</snapshotPolicy>
</repository>
</repositories>
</profile>
-->
<!--
| Here is another profile, activated by the system property 'target-env' with a value of 'dev',
| which provides a specific path to the Tomcat instance. To use this, your plugin configuration
| might hypothetically look like:
|
| ...
| <plugin>
| <groupId>org.myco.myplugins</groupId>
| <artifactId>myplugin</artifactId>
|
| <configuration>
| <tomcatLocation>${tomcatPath}</tomcatLocation>
| </configuration>
| </plugin>
| ...
|
| NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
| anything, you could just leave off the <value/> inside the activation-property.
|
<profile>
<id>env-dev</id>
<activation>
<property>
<name>target-env</name>
<value>dev</value>
</property>
</activation>
<properties>
<tomcatPath>/path/to/tomcat/instance</tomcatPath>
</properties>
</profile>
-->

| List of profiles that are active for all builds.

さて、この修正したsettings.xmlをDockerfileと同じとこに置く
(今回の例では、という意味で必須ではない)
/(root)/Dockerfile
/(root)/Settings.xml
という状態にして最後にsettings.xmlをぶち込み直す
FROM openjdk:8-jdk-alpine
ENV http_proxy http://proxy:port
ENV https_proxy http://proxy:port
RUN apk --update add git openssh maven && \
rm -rf /var/lib/apt/lists/* && \
rm /var/cache/apk/*
COPY settings.xml /usr/share/java/maven-3/conf/settings.xml
ENV BOOT_SLEEP=0 \
JAVA_OPTS=""
RUN addgroup -S scoold && adduser -S -G scoold scoold && \
mkdir -p /scoold/clone && \

RUN git config --global http.proxy http://proxy:port && \

これで全てのプロキシ設定が終わり。
プロキシ地獄に苦しむ方々の参考になれば
おまけ
上記のDockerfileはまだ通らない
cd /scoold/cloneと移動しているはずなのに
mv target/scoold-*.jar /scoold/
が見つからない言われる
とりあえず
mv /scoold/clone/target/scoold-*.jar /scoold/
こうして直接探してやるとあっさり見つかる
よくわからない
