Docker配置代理

        有时候我们在使用docker下载镜像的时候可能想要配置代理区下载那么本文就给大家分享一下docker怎么配置代理。

        假设你已经有了代理，那就编辑/usr/lib/systemd/system/docker.service

        在[Service]下添加

Environment="HTTP_PROXY=http://127.0.0.1:6666/"
Environment="HTTPS_PROXY=http://127.0.0.1:6666/"
Environment="NO_PROXY=localhost,127.0.0.1"
 
# HTTP_PROXY和HTTPS_PROXY填写代理地址
# NO_PROXY填写哪些地址不需要走代理

[root@bogon ~]# cat /usr/lib/systemd/system/docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service time-set.target
Wants=network-online.target containerd.service
Requires=docker.socket
 
[Service]
Type=notify
Environment="HTTP_PROXY=http://127.0.0.1:6666/"
Environment="HTTPS_PROXY=http://127.0.0.1:6666/"
Environment="NO_PROXY=localhost,127.0.0.1"
# 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 -H fd:// --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=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.
LimitNPROC=infinity
LimitCORE=infinity
# Older systemd versions default to a LimitNOFILE of 1024:1024, which is insufficient for many
# applications including dockerd itself and will be inherited. Raise the hard limit, while
# preserving the soft limit for select(2).
LimitNOFILE=1024:524288
 
# 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

接下来重启服务即可

sudo systemctl daemon-reload
sudo systemctl restart docker
