说明

　　根据https://github.com/halo-dev/halo项目，自动化构建镜像。

Dockerfile

直接上Dockerfile，使用说明及注意事项在后面

FROM alpine:3.18.2 as builder

# 安装基础环境
RUN apk update && \
    apk add openjdk17 nodejs npm make bash && \
    npm config set registry https://registry.npmmirror.com && \
    npm -g i pnpm

ADD ./halo /halo
WORKDIR /halo

# RUN version=$(grep -oP 'version=\K[^ ]+' gradle.properties | cut -d'=' -f2)
RUN sed -i 's/services.gradle.org\/distributions/mirrors.cloud.tencent.com\/gradle/g' gradle/wrapper/gradle-wrapper.properties

# 由于插件需要从github下载，正常情况会下载失败
# 所以把需要提前安装的插件放到halo/application/src/main/resources/presets/plugins目录下（需要手动创建）
# 如果不想安装任何插件，只需创建plugin目录就好
# 如果可以正常访问github，不要创建plugins目录，会自动下载默认插件
# mkdir -p halo/application/src/main/resources/presets/plugins
RUN if ls ./application/src/main/resources/presets/plugins > /dev/null 2>&1; \
    then \
        make -C console build && \
        ./gradlew clean build -x check; \
    else \
        make -C console build && \
        ./gradlew downloadPluginPresets && \
        ./gradlew clean build -x check; \
    fi

RUN cd application/build/libs && \
    java -Djarmode=layertools -jar application-*.jar extract

使用说明

把Dockerfile文件和halo项目放到同级目录，根据自己的网络环境，决定是否创建plugins目录，
目录结构如下：

build-halo2
├── Dockerfile
└── halo
    ├── CODE_OF_CONDUCT.md
    ├── CONTRIBUTING.md
    ├── ..........
    ├── platform
    └── settings.gradle

10 directories, 12 files

# 构建镜像
[root@jorelSpace build-halo2]#  docker build -t halo:2.10.2 .

注意事项

由于插件需要从 github下载，如果连接 github超时，只需要在halo项目的 application/src/main/resources目录中创建 presets/plugins目录，即可跳过联网下载插件
如果要预置插件，把下载好的插件放入到创建的 plugins目录中即可。
创建目录命令如下：

[root@jorelSpace build-halo2]# mkdir -p halo/application/src/main/resources/presets/plugins
