我在 Ubuntu 上作为主机操作系统。
docker --version
Docker 版本 18.09.6，构建 481bc77
microk8s 1.14/beta
启用本地注册表microk2s：
microk8s.enable registry
检查：
watch microk8s.kubectl get all --all-namespaces
容器注册表 pod/registry-577986746b-v8xqc 1/1 运行 0 36m
然后：
编辑：
sudo vim /etc/docker/daemon.json
添加此内容：
{
"insecure-registries" : ["127.0.0.1:32000"]
}
重新开始：
sudo systemctl restart docker
仔细检查，看看是否应用了不安全：
docker info | grep -A 2 Insecure
Insecure Registries: 127.0.0.1:32000 127.0.0.0/8 WARNING: No swap limit support
标签：
docker tag my-registry/my-services/my-service:0.0.1-SNAPSHOT 127.0.0.1:32000/my-service
检查：
docker images
127.0.0.1:32000/my-service 最新 e68f8a7e4675 19 小时前 540MB
推动：
docker push 127.0.01:32000/my-service
我在这里看到我的图片：http: //127.0.0.1 :32000/v2/_catalog
在deployment-local.yml我有，现在正确的图像：
...spec:
containers:
- name: my-service-backend
image: 127.0.0.1:32000/my-service
imagePullPolicy: Always ...
然后申请：
envsubst < ./.local/deployment-local.yml | microk8s.kubectl apply -f -
我懂了：ContainerCreating
经过：microk8s.kubectl describe pods my-service-deployment-f85d5dcd5-cmd5
在事件部分：

好像我的服务卡在那里。
问：可能是什么原因？
更新：
将所有更改为localhost帮助，这意味着我现在可以在浏览器中看到：http://localhost:32000/v2/_catalog。
{"repositories":["my-service"]}
但它只适用于 Firefox.. 很奇怪。在 chrome 中待定..
仍然：
