docker compose错误：yaml.parser.ParserError:应为'&书信电报；文档开始>'；，但是发现'&书信电报；标量>'；

获取错误：

admin1@POC-k8s-master:~/poc-cog/kafka/k8s1$ docker-compose up -d
ERROR: yaml.parser.ParserError: expected '<document start>', but found '<scalar>'
  in "./docker-compose.yaml", line 36, column 1

这不是docker compose文件，无法识别。这是一个用于构建图像的文件。这回答了你的问题吗？
