docker-compose.yml端口上的引号有什么区别? [英] Quotes on docker-compose.yml ports make any difference?

问题描述

我不知道 docker-compose.yml 文件中带引号或不带引号的端口之间是否有区别，找不到任何好的文档.

I don't know if there is a difference between ports with or without quotes in a docker-compose.yml file, can't find any good documentation.

• 带引号

ports:
  - "80:80"
  - "443:443"

• 不带引号

ports:
  - 80:80
  - 443:443

我看到它运行时没什么不同

I see no difference when I run it

推荐答案

Docker Compose文件版本3参考中的注释:

Note from Docker Compose file version 3 reference:

以HOST:CONTAINER格式映射端口时，使用小于60的容器端口可能会遇到错误的结果，因为YAML会将xx:yy格式的数字解析为以60为基数的值.因此，我们建议始终将端口映射明确指定为字符串.

When mapping ports in the HOST:CONTAINER format, you may experience erroneous results when using a container port lower than 60, because YAML parses numbers in the format xx:yy as a base-60 value. For this reason, we recommend always explicitly specifying your port mappings as strings.
