docker仓库登录及配置insecure-registries的方法

目录1. 配置/etc/docker/daemon.json2. 配置systemd启动文件docker client insecure-registries配置

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 [0 root@vps harbor.domain.io]# docker login harbor.domain.io Username: admin Password: Error response from daemon: Get https://harbor.domain.io/v2/: x509: certificate signed by unknown authority [1 root@vps harbor.domain.io]# cp /data/secret/certs/harbor.domain.io.crt .
