Docker-创建Hexo环境

发表于 更新于 分类于

GitHub 访问速度不佳, 在Nas上部署一套Hexo

编写DockerFile

本来是打算看看有没有合适的镜像的, 不是太大, 就是配置太麻烦, 干脆自己自定义一个算了

FROM node:16.0.0-alpine

# 设置代理, 后边装依赖要用
ENV http_proxy http://192.168.186.210:7890
ENV https_proxy http://192.168.186.210:7890

WORKDIR /usr/local

# alpine中什么都没有, 需要单独安装
RUN apk update && apk add bash && apk add git
SHELL ["/bin/bash", "-o", "pipefail", "-c"]

RUN unset http_proxy && unset https_proxy

# hexo端口
EXPOSE 4000

# 这个脚本后面可以自己替换
COPY start.sh /usr/local/start.sh
RUN chmod +x /usr/local/start.sh
CMD ["/bin/bash", "-c", "./start.sh"]

start.sh

if [ ! -d "/usr/local/xweiba.github.io" ]; then
  git clone -b source https://github.com/xweiba/xweiba.github.io.git&&npm config set registry https://registry.npmmirror.com&&npm install hexo-cli -g
fi
cd /usr/local/xweiba.github.io
git pull --force&&npm install&&hexo clean&&hexo s

构建镜像并启动

构建镜像:

1
docker build -t wb-hexo:v1 .

启动, 第一次会比较慢, 后面就好了

1
2
docker run -itd --name hexo -p 4000:4000 --restart always wb-hexo:v1
docker container logs -f hexo

添加Nginx配置

定时拉取更新

alpine 镜像的 cron 功能应该是废的, 直接在宿主机上执行, 半小时执行一次.
