docker是yum安裝版本是19.03.5
yum安裝的此版本/etc/docker/並沒有daemon.json文件
然后修改vim /usr/lib/systemd/system/docker.service
#在ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock 后加--insecure-registry=10.200.10.10:5000
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry=10.200.10.10:5000
systemctl daemon-reload
systemctl restart docker
docker login 10.200.10.10:5000 還是報錯5000: connect: connection refused
然后在/etc/docker/添加daemon.json文件
{ "insecure-registries":["10.200.10.10:5000"] }
systemctl daemon-reload
systemctl restart docker
docker 啟動不了
查找報錯后發現此版本/etc/docker的文件名得寫成daemon.json.rpmsave
/etc/docker/daemon.json.rpmsave
systemctl daemon-reload
systemctl restart docker
測試ok
