复制失败：生成上下文docker组合[重复]之外的禁止路径

Question

这是项目结构

Project
 /deployment
   /Dockerfile
   /docker-compose.yml
 /services
   /ui
     /widget

这是docker文件

FROM node:14

WORKDIR /app

USER root

# create new user (only root can do this) and assign owenership to newly created user
RUN echo "$(date '+%Y-%m-%d %H:%M:%S'): ======> Setup Appusr" \
    && groupadd -g 1001 appusr \
    && useradd -r -u 1001 -g appusr appusr \
    && mkdir /home/appusr/ \
    && chown -R appusr:appusr /home/appusr/\
    && chown -R appusr:appusr /app

# switch to new created user so that appuser will be responsible for all files and has access
USER appusr:appusr

COPY ../services/ui/widget/ /app/
COPY ../.env /app/

# installing deps
RUN npm install 

x-env: &env
  HOST: 127.0.0.1

services:
  widget:
    build:
      dockerfile: Dockerfile
      context: .
    ports:
      - 3002:3002
    command:
      npm start
    environment:
      <<: *env
    restart: always

Step 6/8 : COPY ../services/ui/widget/ /app/
ERROR: Service 'widget' failed to build : COPY failed: forbidden path outside the build context: ../services/ui/widget/ ()

Answer 1

不能在存在DockerFile的当前路径之外复制或添加文件。

您应该将这两个目录移动到dockerfile所在的位置，然后将dockerfile更改为：

COPY ./services/ui/widget/ /app/
COPY ./.env /app/

或者在docker-compose中使用volumes，并删除两行copy。

x-env: &env
  HOST: 127.0.0.1

services:
  widget:
    build:
      dockerfile: Dockerfile
      context: .
    ports:
      - 3002:3002
    command:
      npm start
    environment:
      <<: *env
    restart: always
    volumes:
      - /absolute/path/to/services/ui/widget/:/app/
      - /absolute/path/to/.env/:/app/

如果在docker-compose`中使用volumes，这应该是您的dockerfile：

FROM node:14

WORKDIR /app

USER root

# create new user (only root can do this) and assign owenership to newly created user
RUN echo "$(date '+%Y-%m-%d %H:%M:%S'): ======> Setup Appusr" \
    && groupadd -g 1001 appusr \
    && useradd -r -u 1001 -g appusr appusr \
    && mkdir /home/appusr/ \
    && chown -R appusr:appusr /home/appusr/\
    && chown -R appusr:appusr /app

# switch to new created user so that appuser will be responsible for all files and has access
USER appusr:appusr

# installing deps
RUN npm install
