编辑:Docker版本17.12.0-ce,构建c97c6d6在OSX High Sierra 10.12.6上
我正在将webpacker包含到现有的rails 4.2项目中(某些部分仍然使用sprockets)并且已经遇到热重新加载的一些问题。我的应用程序是dockerized,我希望有一个设置,我可以编辑我的React代码,并在我的rails docker容器中编译和刷新它,而不需要为每个小的更改重建(例如docker-compose build)。
目前我正在运行webpack-dev-server并正确编译代码。 webpack dev服务器(http://dockerhost:3035/webpack-dev-server/)将从我的本地计算机编译卷装入的代码,但是当我刷新rails应用程序时,新编译的资产将不会出现。我的设置有什么明显的错误吗?

答案 0 :(得分:2)
我不太熟悉w / webpacker
但是看着你的配置,我的猜测是你使用0.0.0.0:3035
地址从web
容器中访问dev-server资产应该是webpacker:3035
。
尝试更新WEBPACKER_DEV_SERVER_HOST
服务配置中的web
:
web:
...
environment:
...
- WEBPACKER_DEV_SERVER_HOST=webpacker
