ERROR: yaml.parser.ParserError: while parsing a block mapping
  in "././tmp/statelesscs_compose.yml", line 1, column 1
expected <block end>, but found ':'
  in "././tmp/statelesscs_compose.yml", line 4, column 1
docbase installation completed

执行下面的yml file.can时,请建议我如何解决这个问题.

用法示例:

docker-compose -f my.yml up

也让我知道是否有任何格式化yml文件的工具,以便我可以轻松修改

my.yml:

version: '2'
services:
  ubuntupgcsstateless:
    image: ubuntupgstatelesscsimage
    environment:
      - EXTERNAL_IP=10.31.86.164
      - EXTERNALDB_IP=10.31.86.165
      - EXTERNALDB_ADMIN_USER=postgres
      - EXTERNALDB_ADMIN_PASSWORD=password
      - DOCBASENAME=DocbaseName
    hostname:
      "ubuntupgcsstateless"
    container_name:
      "ubuntupgcsstateless"
    ports:
     - "1689:1689"
     - "1690:1690"
     - "50000:50000"
     - "50001:50001"
     - "9080:9080"
     - "9082:9082"
    volumes:
     - DocbaseName_data:/home/dmadmin/dctm/data
     - DocbaseName_dba:/home/dmadmin/dctm/dba
     - DocbaseName_share:/home/dmadmin/dctm/share
     - DocbaseName_dfc:/home/dmadmin/dctm/config …

我在命令行终端中收到此错误:

在第18行第7行解析块映射时没有找到预期的键

我的jekyll _config.yml YAML文件如下所示:

title: Oliver Williams - Portfolio
url: "http://yourdomain.com" # the base hostname & protocol for your site

# Build settings
markdown: kramdown
permalink: /:title

defaults:
  -
    scope:
      path: "" # an empty string here means all files in the project
      type: "posts" # previously `post` in Jekyll 2.2.
    values:
      layout: "post"

       -
    scope:
      path: "" # an empty string here means all files in the project
      type: "pages" 
    values:
      layout: "page"
