在 docker-compose 中使用构建命令时出现 rpc 错误

Question

我在windwos10中使用Docker桌面。 I have a docker compose file with 2 container (one with a simple python and and a mysql) when running the docker file (which is multistage) for the python app it works fine, but when trying to run it from the docker compose I get an rpc error, which I have been for one day trying to find a solution in the official docker forums (as I have been learning docker for just 2 weeks) and here but nothing I found it is working(I tried giving more memory to docker桌面，限制memory每个容器使用量...）。 这是我的 dockerfile：

version: "3.7"
services:
  webapp:
    build: 
      context: .
      dockerfile: Dockerfile
    ports:
      - "3000:3000"
    environment:
      FLASK_ENV: development
      FLASK_RUN_HOST: 0.0.0.0
    mem_limit: 1GB
    networks:
      - app_network 

  mysql:
    image: mysql:8.0.13
    restart: always
    ports:
      - 3306:3306
    command: --init-file ./init.sql
    environment:
      MYSQL_ROOT_USER: "root"
      MYSQL_ROOT_PASSWORD: "admin"
      MYSQL_USER: "user-flask"
      MYSQL_PASSWORD: "password123"
    mem_limit: 1GB
    volumes:
      - ./schemas:/var/lib/mysql:rw
    networks:
      - app_network 
volumes:
  schemas: {}
networks:
  app_network:
    name: app_net
    driver: bridge

Dockerfile：

FROM python:3.8-alpine as builder
WORKDIR /code
COPY ./myapp/requirements.txt requirements.txt
RUN apk update \
    && apk add --virtual build-deps gcc python3-dev musl-dev \
    && apk add --no-cache mariadb-dev
RUN pip install --user -r requirements.txt

FROM python:3.8-alpine
WORKDIR /code
RUN apk add --no-cache mariadb-dev
COPY --from=builder /root/.local /root/.local
ADD ./myapp .
ENV PATH=/root/.local:$PATH
ENV FLASK_APP App.py
ENV FLASK_RUN_HOST 0.0.0.0
ENV FLASK_RUN_PORT 3000
CMD ["python", "-m", "flask", "run"] 

这是我得到的 output 错误：

#13 11.95 ERROR: unable to select packages:
#13 11.97   apk (no such package):
#13 11.97     required by: build-deps-20210215.104420[apk]

有没有人至少暗示在哪里寻找？ 到目前为止，我所发现的只是为 Docker 桌面提供更多资源并将资源限制在容器中，但这似乎不起作用。

看起来你刚刚在下面的第三行中丢失了&&

RUN apk update \
    && apk add --virtual build-deps gcc python3-dev musl-dev \
    apk add --no-cache mariadb-dev
