纱失败的Dockerfile

Question

运行我安装yarn，然后我想用接下来的Dockerfile来执行它：

FROM ubuntu:trusty 
.... 
USER node 
RUN npm install -g yarn 
RUN ["/bin/bash", "-c","yarn install"] 

但它失败：

/bin/bash: yarn: command not found 
ERROR: Service 'falink-frontend4' failed to build: The command '/bin/bash -c yarn install' returned a non-zero code: 127 

我只是尝试使用下一个：

FROM ubuntu:trusty 
....  
USER node 
RUN npm install -g yarn 
RUN yarn install 

但它无法用：

/bin/sh: 1: yarn: not found 
ERROR: Service 'falink-frontend4' failed to build: The command '/bin/sh -c yarn install' returned a non-zero code: 127 

然后我连接到容器使用docker exec -it XXXXX /bin/bash，我运行yarn install它工作正常。当我在Docker容器内访问时，我使用node用户作为Dockerfile。

这是我entery Dockerfile：

FROM ubuntu:trusty 

# Create app directory 
RUN mkdir -p /usr/src/app 


#use mirrors for faster apt downloads no matter where the machine that builds the image is

可能是什么问题呢？

如果你仍然需要调整ubuntu:trusty图片，这个Dockerfile，灵感来自官方docker hub node:latest有一个功能yarn工作。

RUN yarn --help 

我会在构建结束看到yarn --verion输出：
