Question

我正在使用https://docs.docker.com/compose/compose-file/#extension-fields将相同的配置共享到多个容器。

我试图将一个元素添加到列表中而没有成功。

version: '3.4'

x-volumes:
  &data
    - .:/code
    - ~/.ssh:/opt/data/home/developer/.ssh:ro
    - ~/.bashrc:/opt/data/home/developer/.bashrc.d/bashrc.sh:ro

services:
  nginx:
    image: nginx
    volumes:
      << : *data
      - ./docker/conf/nginx_vhost.conf:/etc/nginx/conf.d/app.conf:ro
    depends_on:
      - fpm

我什至尝试过

version: '3.4'

x-volumes:
  &data
    - .:/code
    - ~/.ssh:/opt/data/home/developer/.ssh:ro
    - ~/.bashrc:/opt/data/home/developer/.bashrc.d/bashrc.sh:ro

services:
  nginx:
    image: nginx
    volumes:
      *data
      - ./docker/conf/nginx_vhost.conf:/etc/nginx/conf.d/app.conf:ro
    depends_on:
      - fpm

但是每次我收到无效的YAML错误。

第一次尝试错误

ERROR: yaml.parser.ParserError: while parsing a block mapping
  in "./docker-compose.yml", line 13, column 7
expected <block end>, but found '-'
  in "./docker-compose.yml", line 14, column 7

第二次尝试错误

ERROR: yaml.parser.ParserError: while parsing a block mapping
  in "./docker-compose.yml", line 11, column 5
expected <block end>, but found '<block sequence start>'
  in "./docker-compose.yml", line 14, column 7

我尝试了一些Stackoverflow答案，但没有成功，例如https://stackoverflow.com/a/41728592/4487542

有可能吗？
