一. 背景

Docker login 登录harbor镜像仓库报错.

[root@master01 sloth]# docker login docker.harbor.master01.comUsername: bigdataPassWord:Error response from daemon: Get https://docker.harbor.master01.com/v2/: x509: certificate signed by unknown authority[root@master01 sloth]#

二. 解决方式

1. 修改docker配置文件, 将访问的镜像仓库地址加入到docker的/etc/docker/daemon.JSON配置中. 新增参数 insecure-reGIStries.

[root@master01 sloth]# more /etc/docker/daemon.json{  "exec-opts": ["native.cgroupdriver=systemd"],  "log-driver": "json-file",  "log-opts": {    "max-size": "100m"  },  "storage-driver": "overlay2",  "insecure-registries": ["docker.harbor.master01.com", "要忽略的image仓库请求地址"]}

2. 重启docker服务

systemctl restart docker

3. 登录

[root@master01 sloth]# docker login   docker.harbor.master01.comUsername: adminPassword:WARNING! Your password will be stored unencrypted in /root/.docker/config.json.Configure a credential helper to remove this warning. SeeHttps://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded[root@master01 sloth]#
