前言
本项目主要参考cirruslabs的两个Docker脚本
本笔记主要是简化和增加一些实际过程中一些经验总结
最简单实践案例
指定SDK版本
Dockerfile
FROM cirrusci/android-sdk:tools
ENV ANDROID_PLATFORM_VERSION 29
ENV ANDROID_BUILD_TOOLS_VERSION 29.0.2
RUN yes | sdkmanager \
"platforms;android-$ANDROID_PLATFORM_VERSION" \
"build-tools;$ANDROID_BUILD_TOOLS_VERSION"
编译镜像，和上面Dockerfile同级目录执行
docker build -t "image_name" .
- -t 指定镜像名称；
-
.当前目录找Dockerfile 编译文件
如果需要多个SDK的话，可以在上次编译镜像的基础上叠一层，修改Dockfile
<font color=red>建议不要叠太多SDK，否则最终的镜像会很大，而且正式环境是不需要多个SDK的</font>
Dockerfile
FROM <上次编译的镜像名称或者ID>
ENV ANDROID_PLATFORM_VERSION 29
ENV ANDROID_BUILD_TOOLS_VERSION 29.0.2
RUN yes | sdkmanager \
"platforms;android-$ANDROID_PLATFORM_VERSION" \
"build-tools;$ANDROID_BUILD_TOOLS_VERSION"
备注： 这里提供自己编译好的SDK版本，本人比较懒提供常用编译好的SDK
dockerlinz/android-sdk:29
dockerlinz/android-sdk:28
dockerlinz/android-sdk:27
指定flutter版本
Dockerfile
FROM dockerlinz/android-sdk:27
ARG flutter_version
ENV FLUTTER_HOME=${HOME}/sdks/flutter \
FLUTTER_ROOT=$FLUTTER_HOME \
FLUTTER_VERSION=$flutter_version \
PUB_HOSTED_URL=https://pub.flutter-io.cn \
FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
RUN mkdir -p ${FLUTTER_HOME}
ENV PATH ${PATH}:${FLUTTER_HOME}/bin:${FLUTTER_HOME}/bin/cache/dart-sdk/bin
RUN git clone --branch ${FLUTTER_VERSION} https://github.com/flutter/flutter.git ${FLUTTER_HOME} && \
flutter doctor
这里我们使用v1.9.1-hotfixes分支
docker build --tag --build-arg flutter_version=v1.9.1-hotfixes
测试
进入flutter工程所在目录
docker run --rm -it -v ${PWD}:/build --workdir /build dockerlinz/flutter:stable flutter build apk
可以加入 -v ~/.gradle:/home/cirrus/.gradle --env GRADLE_USER_HOME=/home/cirrus/.gradle，挂在本地缓存到镜像中
<font color=red> 注意：过来人经验，此处没有把握的话还是进入容器里面测试会更省事</font>
docker run --rm -it -v ${PWD}:/build --workdir /build dockerlinz/flutter:stable
进入后需要重新生成.packages
fluter clean
flutter packages get
最好进入android或mac目录执行以下原生编译脚本，查看编译环境
./gradlew build -d
最后才是flutter编译
flutter build apk
出现的问题
问题一：本地正常跑，但是镜像中很多依赖下载不下来
- <font color=red> android studio Could not download guava.jar</font>
- <font color=red> Could not download kotlin-gradle-plugin.jar</font>
- <font color=red>flutter Build file '/build/android/app/build.gradle' line: 25</font>
- <font color=red>Could not download kotlin-reflect.jar org.jetbrains.kotlin:kotlin-reflect:1.2.0</font>
解决：方案
-
在gradle中增加阿里云国内镜像
buildscript { repositories { maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' } google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.3.1' } } allprojects { repositories { maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' } google() jcenter() } } -
挂载本地gradle 缓存到镜像中
docker run --rm -it -v ${PWD}:/build --workdir /build -v ~/.gradle:/home/cirrus/.gradle --env GRADLE_USER_HOME=/home/cirrus/.gradle dockerlinz/flutter:stable
问题二： flutter build apk 缓慢
每次都下载gradle版本，导致每次重新下载gradle版本
解决方案一
挂在本地缓存到镜像中
-v ~/.gradle:/home/cirrus/.gradle --env GRADLE_USER_HOME=/home/cirrus/.gradle
解决方案二
-
挂在.gradle 缓存目录，不用每次编译的时候重新下载依赖
-v ~/.gradle2:/home/cirrus/.gradle -
在叠一层gradle环境
#https://github.com/frekele/docker-gradle/blob/master/Dockerfile FROM dockerlinz/flutter:1.9.1-hotfixes # Change to tmp folder ENV GRADLE_VERSION=4.10.2 ENV GRADLE_HOME=/opt/gradle ENV GRADLE_FOLDER=/root/.gradle # Change to tmp folder WORKDIR /tmp # Download and extract gradle to opt folder RUN wget --no-check-certificate --no-cookies https://downloads.gradle.org/distributions/gradle-${GRADLE_VERSION}-bin.zip \ && sudo unzip gradle-${GRADLE_VERSION}-bin.zip -d /opt \ && sudo ln -s /opt/gradle-${GRADLE_VERSION} /opt/gradle \ && sudo rm -f gradle-${GRADLE_VERSION}-bin.zip # Add executables to path RUN sudo update-alternatives --install "/usr/bin/gradle" "gradle" "/opt/gradle/bin/gradle" 1 && \ sudo update-alternatives --set "gradle" "/opt/gradle/bin/gradle" # Create .gradle folder RUN sudo mkdir -p $GRADLE_FOLDER # Mark as volume VOLUME $GRADLE_FOLDER # Add the files #ADD rootfs / # Change to root folder WORKDIR /home/cirrus/ -
Flutter 中Android工程指定本地gradle编译，不是取下载，文件目录
<android_project>/.idea/gradle.xml<?xml version="1.0" encoding="UTF-8"?> <project version="4"> <component name="GradleSettings"> <option name="linkedExternalProjectsSettings"> <GradleProjectSettings> <compositeConfiguration> <compositeBuild compositeDefinitionSource="SCRIPT" /> </compositeConfiguration> <option name="distributionType" value="LOCAL" /> <option name="externalProjectPath" value="$PROJECT_DIR$" /> <option name="gradleHome" value="$USER_HOME$/.gradle/wrapper/dists/gradle-4.4-all/9br9xq1tocpiv8o6njlyu5op1/gradle-4.4/bin" /> <option name="resolveModulePerSourceSet" value="false" /> <option name="testRunner" value="PLATFORM" /> </GradleProjectSettings> </option> </component> </project>- distributionType 改为
LOCAL - gradleHome 指向
gradle_home/bin
- distributionType 改为
