Docker 容器中的浏览器同步 [英] Browsersync within a Docker container

问题描述

我有一个 Wordpress/MySQL docker 容器，用于开发主题和插件.我在 localhost:8000 上访问它.

I've got a Wordpress/MySQL docker container, which I use for developing themes & plugins. I access this on localhost:8000.

它使用 Gulp 构建过程 &我正在尝试将 browsersync 添加到组合中.我很难让 browsersync 真正从容器中代理出来.从 Gulp 输出中，我可以看到它生成了更改，只是实际上并未在浏览器中进行任何更改.

It uses a Gulp build process & I am trying to add browsersync to the mix. I'm having a hard time getting the browsersync to actually proxy out of the container. From the Gulp output I can see that its generating the changes, just not actually making any changes in the browser.

这是我的 docker-compose.yml、gulpfile、dockerfile &shell 脚本.

Heres my docker-compose.yml, gulpfile, dockerfile & shell script.

docker-compose.yml 指的是以下 dockerfile:

The docker-compose.yml refers to the following dockerfile:

FROM node

# Grab our version variable from the yml file
ARG SITE_VERSION

# Install gulp globally
RUN npm install -g gulp node-gyp node-sass

# Install dependencies
COPY ./gulp-build.sh /
RUN chmod 777 /gulp-build.sh
ENTRYPOINT ["/gulp-build.sh"]
CMD ["run"]

安装 gulp 和 node-sass，并将以下 gulp-guild.sh 脚本复制到容器中:

which installs gulp and node-sass, and also copies the following gulp-guild.sh script into the container:

#!/bin/bash

cd /var/www/html/wp-content/themes/theme
# npm rebuild node-sass && npm install && gulp --dev
npm rebuild node-sass && npm install && gulp

推荐答案

您的配置的主要问题是您指向 gulpfile 中的 localhost.这指向本地容器，而不是您的主机，因此 browsersync 将无法连接到 Wordpress.

The primary problem with your configuration is that you're pointing to localhost in the gulpfile. This points to the local container, not your host machine, so browsersync won't be able to connect to Wordpress.

您首先需要更新 gulpfile 以指向 wordpress 服务的内部端口:

You first need to update the gulpfile to point to the wordpress service, on its internal port:

browserSync.init(files, {
    // The hostname is the name of your service in docker-compose.yml.
    // The port is what's defined in your Dockerfile.
    proxy: "wordpress:3000",
    notify: false,
    // Do not open browser on start
    open: false
})

然后您需要添加端口映射以从您的 node 服务公开浏览器同步服务器.在您的 docker-compose.yml 文件中:

Then you need to add a port mapping to expose the browsersync server from your node service. In your docker-compose.yml file:

node:
    ports:
        - "3000:3000"
        - "3001:3001"

您现在应该可以访问 localhost:3001 上的浏览​​器同步代理.

You should now be able to access the browsersync proxy on localhost:3001.

附言如果您在一个 ngninx docker 容器中有多个站点服务，您可以在/etc/nginx/conf.d/somesite.conf 中编辑特定站点的 nginx 配置文件并添加新行:听:3000;

P.S. In case you have more than one site serving in one ngninx docker container, you can edit nginx config file for specific site in /etc/nginx/conf.d/somesite.conf and add new line: listen: 3000;
