：启动容器进程导致"exec：\"sudo\"：找不到可执行文件

Question

错误:无法启动服务cpanel_client:头字段值无效"oci运行时错误: container_linux.go:247:启动容器进程导致"exec：\"sudo\"：找不到可执行文件

这是我的docker文件，

FROM node:8.1.2-alpine

WORKDIR /control-panel
COPY package.json /control-panel/package.json
RUN npm install auth0-lock mapbox-gl mapbox-gl-geocoder tinymce angular2-jwt aws-sdk @angular/cli hammerjs jquery moment moment-timezone bootstrap@3 jquery-ui-dist --save
RUN mv /control-panel/node_modules /node_modules
COPY . /control-panel
EXPOSE 4200
EXPOSE 49153

这是docker compose.yml，

cpanel_client:
    build: .
    ports:
        - "4200:4200"
        - "49153:49153"
    volumes:
        - .:/control-panel
    command: npm start

我的package.json文件，

构建成功。当我运行docker-compose run –rm cpanel_client ng init –skip-npm –name CliDemo时，我得到了这个错误。谁能告诉我我哪里错了？

Answer 1

默认情况下，node_modules/.bin文件夹不在$PATH中。您只需直接调用路径：

command: /control-panel/node_modules/.bin/ng serve --host 0.0.0.0

Answer 2

您的映像上似乎没有安装sudo。请注意错误消息：

"exec: \"sudo\": executable file not found

有人试图sudo (“超级用户做”)某件事，但做不到。尝试通过包管理器安装sudo来平息该步骤，或者尝试配置该步骤以不需要超级用户权限。
