錯誤現象

[[email protected] data]# docker pull harbor.enncloud.cn/enncloud/hyperkube-amd64:v1.11.2
Error response from daemon: Get https://harbor.enncloud.cn/v1/_ping: x509: failed to load system roots and no roots provided
 

原因是未設定 “insecure-registries”: [“example.com”]不安全映象倉庫的域名 解決辦法

{
 "insecure-registries": ["example.com"],
  "hosts": ["unix:///var/run/docker.sock"],
  "storage-driver": "devicemapper",
  "storage-opts": [
  "dm.basesize=10G",
  "dm.thinpooldev=/dev/mapper/docker-thinpool",
  "dm.use_deferred_removal=true",
  "dm.use_deferred_deletion=true"
  ],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "20m",
    "max-file": "10"
  }
}
 

重新登入 docker login -u user -p password 搞定
