kubernetes：容器未开始使用私有注册表

Question

我有一个在 debian 上运行的 kubernetes 1.1.1 的工作安装

我还有一个在 v2 中运行良好的私有注册表..

我正面临一个奇怪的问题。

在 master 中定义一个 pod

apiVersion: v1
kind: Pod
metadata:
name: nginx
labels:
app: nginx
spec:
containers:
- name: nginx
image: docker-registry.hiberus.com:5000/debian:ssh
imagePullSecrets:
- name: myregistrykey

我的主myregistrykey kubernetes.io/dockercfg 1 44m上也有秘密myregistrykey kubernetes.io/dockercfg 1 44m

我的 config.json 就是这样制作的

{
"auths": {
"https://docker-registry.hiberus.com:5000": {
"auth": "anNhdXJhOmpzYXVyYQ==",
"email": "jsaura@heraldo.es"
}
}
}

所以我做了 base64 并创建了我的秘密。

简单到地狱

在我的节点上，图像被拉出没有任何问题

docker images

但我的容器没有启动

它在内部循环尝试启动，但从未启动

奇怪的是，如果你在我的节点上手动执行运行命令，容器启动没有任何问题，但使用 pod 拉图像但从未启动..

难道我做错了什么？

如果我为我的 pod 使用公共图像，它启动时没有任何问题..这只会在使用私有图像时发生在我身上..

我也从 debian 转移到 ubuntu，没有运气同样的问题

我还将秘密链接到默认服务帐户，仍然没有运气

克隆了最后一个 git 版本，编译，没有运气..

对我来说很明显问题是使用私有注册表，但我已经申请并遵循了我阅读的所有信息，但仍然没有运气。

Answer 1

如果 docker 容器的主进程已退出，则它可能会退出。 你能分享容器日志吗？

1. 如果你执行docker ps -a你应该看到所有正在运行和退出的容器
2. 运行docker container logs container_id

还尝试以交互和守护程序模式运行您的容器，看看它是否仅在守护程序模式下失败。

在守护进程模式下运行 -

docker run -d -t Image_name

以交互模式运行 -

docker run -it Image_name

对于交互式守护进程模式docker run -idt Image_name
