AWT错误，同时试图build立Jenkins基于高山的Docker图像 –

我正在尝试构build我自己的Jenkins Docker镜像。 我使用基于Alpine的Jdk Docker镜像 。 我调整了Alpine-Linux的Jenkins Docker镜像 。 我不得不安装一些软件包以便正确构build，但是一旦我运行它，就会出现以下错误：

hudson.util.AWTProblem: java.lang.NullPointerException at hudson.WebAppMain.contextInitialized(WebAppMain.java:185) at org.eclipse.jetty.server.handler.ContextHandler.callContextInitialized(ContextHandler.java:782) at org.eclipse.jetty.servlet.ServletContextHandler.callContextInitialized(ServletContextHandler.java:424) at org.eclipse.jetty.server.handler.ContextHandler.startContext(ContextHandler.java:774) at org.eclipse.jetty.servlet.ServletContextHandler.startContext(ServletContextHandler.java:249) at org.eclipse.jetty.webapp.WebAppContext.startContext(WebAppContext.java:1242) at org.eclipse.jetty.server.handler.ContextHandler.doStart(ContextHandler.java:717) at org.eclipse.jetty.webapp.WebAppContext.doStart(WebAppContext.java:494) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:64) at org.eclipse.jetty.server.handler.HandlerWrapper.doStart(HandlerWrapper.java:95) at org.eclipse.jetty.server.Server.doStart(Server.java:282) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:64) at winstone.Launcher.<init>(Launcher.java:156) at winstone.Launcher.main(Launcher.java:356) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at Main._main(Main.java:293) at Main.main(Main.java:98) Caused by: java.lang.NullPointerException at sun.awt.FontConfiguration.getVersion(FontConfiguration.java:1264) at sun.awt.FontConfiguration.readFontConfigFile(FontConfiguration.java:219) at sun.awt.FontConfiguration.init(FontConfiguration.java:107) at sun.awt.X11FontManager.createFontConfiguration(X11FontManager.java:774) at sun.font.SunFontManager$2.run(SunFontManager.java:431) at java.security.AccessController.doPrivileged(Native Method) at sun.font.SunFontManager.<init>(SunFontManager.java:376) at sun.awt.FcFontManager.<init>(FcFontManager.java:35) at sun.awt.X11FontManager.<init>(X11FontManager.java:57) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442) at sun.font.FontManagerFactory$1.run(FontManagerFactory.java:83) at java.security.AccessController.doPrivileged(Native Method) at sun.font.FontManagerFactory.getInstance(FontManagerFactory.java:74) at java.awt.Font.getFont2D(Font.java:491) at java.awt.Font.getFamily(Font.java:1220) at java.awt.Font.getFamily_NoClientCode(Font.java:1194) at java.awt.Font.getFamily(Font.java:1186) at java.awt.Font.toString(Font.java:1683) at hudson.util.ChartUtil.<clinit>(ChartUtil.java:255) at hudson.WebAppMain.contextInitialized(WebAppMain.java:184) ... 19 more 

我已经尝试了不同的解决scheme，我的朋友Google正在安装fontconfig软件包或添加Java参数

JAVA_OPTS = “ – Djava.awt.headless =真”

或事件将JDK版本更改为7，但似乎没有任何工作。 这是我的dockerfile

希望你们中的一个人能够帮忙，否则我会跟jenkins这个较沉重的官员形象去。 提前致谢。

也许你正在试图完成我所做的： https ： //hub.docker.com/r/serverking/jenkinsdsl/

我也尝试添加不同的依赖关系来解决这个问题，在我的dockerfile下面：

 FROM alpine:latest ENV JAVA_HOME /usr/lib/jvm/java-1.8-openjdk/jre ENV JENKINS_HOME /var/jenkins_home ENV JENKINS_SLAVE_AGENT_PORT 50000 ENV JENKINS_VERSION 2.19.4 # Add scripts and plugin list ADD src / # Packages RUN set -x && \ apk add --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/main && \ apk add --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/community && \ apk update && \ apk upgrade && \ apk add --no-cache ca-certificates supervisor openjdk8 bash git curl zip wget docker ttf-dejavu jq coreutils openssh py2-pip && \ echo "*** fix key permissions ***" && \ chmod 600 /root/.ssh/id_rsa && \ echo "*** Installing docker-compose ***" && \ pip install --upgrade pip && \ pip install docker-compose # Install Jenkins and plugins from plugins.txt RUN set -x && \ echo "*** Installing jenkins ***" && \ curl -sSL --create-dirs --retry 1 http://repo.jenkins-ci.org/public/org/jenkins-ci/main/jenkins-war/${JENKINS_VERSION}/jenkins-war-${JENKINS_VERSION}.war -o /usr/share/jenkins/jenkins.war && \ echo "*** Recursive solve and reduce plugin dependencies ***" && \ bash -c 'curl -sSO https://updates.jenkins-ci.org/current/update-center.actual.json && \ function solve { \ for dependency in $(cat update-center.actual.json | jq --arg p "${1%:*}" -r '"'"'.plugins[] | select(.name == $p) | .dependencies[] | select(.optional == false) | .name + ":" + .version'"'"');do \ echo $dependency >> /var/jenkins_home/plugins.txt; \ solve $dependency; \ done \ } && \ for plugin in $(tr '"'"'\n'"'"' '"'"' '"'"' < /var/jenkins_home/plugins.txt);do solve $plugin; done && \ sort -Vr /var/jenkins_home/plugins.txt | sort -u -t: -k1,1 -o /var/jenkins_home/plugins.txt' && \ echo "*** Jenkins install plugins from plugins.txt *** " && \ while read plugin; do \ echo "*** Downloading ${plugin} ***" && \ curl -sSL --create-dirs --retry 3 https://updates.jenkins-ci.org/download/plugins/${plugin%:*}/${plugin#*:}/${plugin%:*}.hpi -o /var/jenkins_home/plugins/${plugin%:*}.jpi && \ touch /var/jenkins_home/plugins/${plugin%:*}.jpi.pinned; \ done < /var/jenkins_home/plugins.txt EXPOSE 8080 8443 50000 ENTRYPOINT ["/usr/bin/supervisord", "-c", "/etc/supervisord.conf"] 

为什么我自己做了而不是使用官方的JenkinsCI Dockerfile？

• 插件也必须是不可变的，否则构build不是确定性的。

• 官方不处理XML和不可变性。 没有人真的想编辑XLM文件。

• 存储不应付docker不可改变的概念，从而执行者煞车。

• build设必须是一次性的，如果存在的话，他们必须重新依附于现有的工作。

现在全部解决了。
