hosts 文件如下

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost
服务器ip             db01       //记住 该文件为 服务端的hostname,即在linux 上输如 hostname 命令出现的名字
# Added by Docker Desktop
10.72.33.120 host.docker.internal
10.72.33.120 gateway.docker.internal
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section

服务端
