集群

public host and public port
  • docker
    • 默认 public host 使用 docker container 的 hostname ip，如果非容器内访问，则需要在 config 中设置，或者设置 PUBLIC_HOST 环境变量。
    • 默认 public port 为 port，如果 expose port，则需要在 config 中设置，或者设置 PUBLIC_PORT 环境变量。
  • kubernetes
    • 设置 config 中的 public host，或者设置 PUBLIC_HOST 环境变量，值为 POD IP。设置参考
    • 设置 config 中的 public port，或者设置 PUBLIC_PORT 环境变量，值为 名称为 fns 的 POD PORT。设置参考
  • 其它环境
    • 默认 public host 使用 config 中的 host，优先使用 config 中的设置，其次为 环境变量，最后是默认。
    • 默认 public port 使用 config 中的 port，优先使用 config 中的设置，其次为 环境变量，最后是默认。
