实时容器中存在新的代码更改，但未反映在浏览器中

Question

我正在使用带有开源 BI 工具 Apache Superset 的 Docker。我添加了一个新文件，特别是 CountryMap 目录中的 .geojson 文件。现在，当我尝试使用docker-compose up --build 构建或在前端进行更改时，Docker 没有完全更新，并且在尝试运行查询时出现文件未找到错误。当我通过docker exec -it container_id bash 查看容器内部时，新文件就在那里。

Dockerfile：

FROM python:3.6-jessie

RUN useradd --user-group --create-home --no-log-init --shell /bin/bash superset

# Configure environment
ENV LANG=C.UTF-8 \
    LC_ALL=C.UTF-8

RUN apt-get update -y

# Install dependencies to fix `curl https support error` and `elaying package configuration warning`
RUN apt-get install -y apt-transport-https apt-utils

# Install superset dependencies
# https://superset.incubator.apache.org/installation.html#os-dependencies
RUN apt-get install -y build-essential libssl-dev \
    libffi-dev python3-dev libsasl2-dev libldap2-dev libxi-dev

# Install extra useful tool for development
RUN apt-get install -y vim less postgresql-client redis-tools

# Install nodejs for custom build

RUN curl -sL https://deb.nodesource.com/setup_10.x | bash - \
    && apt-get install -y nodejs

    user: root:root
    ports:
      - 8088:8088
    depends_on:
      - postgres
      - redis
    volumes:
      # this is needed to communicate with the postgres and redis services
      - ./superset_config.py:/home/superset/superset/superset_config.py
      # this is needed for development, remove with SUPERSET_ENV=production
      - ../../superset:/home/superset/superset

volumes:
  postgres:
    external: false
  redis:
    external: false

为什么会出现未找到的错误？

Answer 1

尝试在volumes:中使用绝对路径

volumes:
  - /home/me/my_project/superset_config.py:/home/superset/superset/superset_config.py
  - /home/me/my_project/superset:/home/superset/superset

Answer 2

这是因为docker-compose 正在使用缓存。如果 dockerfile 和 docker-compose.yml 未更改，则不会重新创建容器映像。为避免这种情况，您应该使用以下标志：

 --force-recreate

--强制重新创建

即使没有配置和镜像，也要重新创建容器 改变了。

出于开发目的，我也喜欢使用以下开关：

-V, --renew-anon-volumes

重新创建匿名卷，而不是从以前的容器中检索数据。
