[英]Creating volumes in docker-compose
I am trying to create a volume between two containers "abba" and "parser".我正在尝试在两个容器“abba”和“parser”之间创建一个卷。
However, when trying to execute docker-compose build
I get this error: "Named volume "data-volume:parser/sample_files:rw" is used in service "parser" but no declaration was found in the volumes section."但是,当尝试执行
docker-compose build
我收到此错误:“命名卷“data-volume:parser/sample_files:rw”用于服务“parser”,但在卷部分中未找到任何声明。”
Here is my compose file:这是我的撰写文件:
version: '3'
services:
abba:
build:
context: ./abba
dockerfile: Dockerfile
command: python abba/manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
- data-volume:./abba/media
ports:
- "8000:8000"
depends_on:
- db
parser:
build:
context: ./parser
dockerfile: Dockerfile
volumes:
- data-volume:./parser/sample_files
db:
image: postgres
volumes:
data_volume:
parser Dockerfile:解析器Dockerfile:
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
EXPOSE 8000:8000
CMD ["python", "./parse.py"]
and abba Dockerfile和阿爸 Dockerfile
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
The thing I don't understand is why I get the error for the "parser" service, but not the "abba" service?我不明白的是为什么我收到“解析器”服务的错误,而不是“abba”服务的错误? It leads me to think that it works for the "abba" service, but not for the "parser" service.
这让我认为它适用于“abba”服务,但不适用于“解析器”服务。 What am I not getting?
我没有得到什么?
Thanks for the help in advance!我在这里先向您的帮助表示感谢!
You have a typo in the volume name in volumes:
section.您在
volumes:
的卷名中有一个错字volumes:
部分。 Change data_volume
to data-volume
.将
data_volume
更改为data-volume
。
