wsl內(nèi)的docker，使用systemd服務(wù)部署的，這時候想要給docker配置代理的話，一定要在systemd配置文件中配置，不能在 ~/.bashrc 中部署，因為systemd 啟動服務(wù)時，實際上是以 獨立的環(huán)境 運行的，通常不會自動加載登錄 shell 中的配置文件（如 /etc/profile 或 ~/.bashrc）。因此，systemd 啟動的進程需要顯式地配置環(huán)境變量才能讓其生效。
systemd服務(wù)配置如下：
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
[Service]
Environment="HTTP_PROXY=http://172.17.144.1:8001"
Environment="HTTPS_PROXY=http://172.17.144.1:8001"
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd --exec-opt native.cgroupdriver=systemd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always
# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3
# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
OOMScoreAdjust=-500
[Install]
WantedBy=multi-user.target

可以看到配置完成之后，就可以正常下載docker鏡像了。
