1. 配置/etc/docker/daemon.json
# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://0nth4654.mirror.aliyuncs.com"],
"insecure-registries": ["harbor.domain.io"]
}
2. 配置systemd启动文件
和方法1配置会有冲突，不可同时配置
[0 root@vps harbor]# cat /usr/lib/systemd/system/docker.service [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service containerd.service Wants=network-online.target Requires=docker.socket containerd.service [Service] 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 -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry harbor.domain.io ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always
docker client insecure-registries配置
- docker客户端如果配置中添加了insecure-registary配置，就不需要在docker 客户端配置上对应证书
- 如果不配置就需要在/etc/docker/certs.d/目录中添加对应证书才能正常登录
