docker - 无效的装载路径 : 'db' mount path must be absolute

Question

以下是我的 docker 文件:

FROM amazon/dynamodb-local
WORKDIR /home/dynamodblocal
RUN mkdir ./db && chown -R 1000 ./db
CMD ["-jar", "DynamoDBLocal.jar", "-dbPath", "./db", "-sharedDb"]
VOLUME ["./db"]

以下是 docker compose 文件:

version: "3.3" 
services:   
dynamodb:
build:
  context: .
  dockerfile: dynamodb/Dockerfile
container_name: email_dynamo
ports:
  - "8000:8000"
volumes:
  - dynamodb-local:/home/dynamodblocal/db   
seed:
image: amazon/aws-cli
container_name: email_dynamo_seed
links:
  - dynamodb
depends_on:
  - dynamodb
command: sh -c "~/seed/seed.sh"
entrypoint: []
volumes:
  - ~/.aws:/root/.aws
  - ./seed:/root/seed 
volumes:   
   dynamodb-local:
    driver: local

当我尝试运行 docker-compose up 时，出现以下错误:

Answer 1

VOLUME 选项中的路径必须是容器中存在的路径。在您的情况下，需要将 VOLUME ["./db"] 更改为:VOLUME ["/home/dynamodblocal/db"]

而 WORKDIR 仅为 RUN、CMD、ENTRYPOINT、COPY 设置默认目录 和 ADD 命令。 不适用于 VOLUME!
