使用Minikube时，不能从私人回购站拉扯码头 [英] Can not pull docker image from private repo when using Minikube

问题描述

我正在尝试使用Minikube进行本地kubernetes开发。我已经设置了我的docker环境，使用在提供的Minikube VM（boot2docker）中运行的docker守护程序，如建议：

I am attempting to use Minikube for local kubernetes development. I have set up my docker environment to use the docker daemon running in the provided Minikube VM (boot2docker) as suggested:

eval $(minikube docker-env)

它设置这些环境变量：

export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/home/jasonwhite/.minikube/certs"

当我尝试从我们的私人码头库存储库中提取图像时：

When I attempt to pull an image from our private docker repository:

docker pull oururl.com:5000/myimage:v1

我收到此错误：

Error response from daemon: Get https://oururl.com:5000/v1/_ping: x509: certificate signed by unknown authority

出现我需要添加一个可信赖的ca根证书，但是在我的尝试中到目前为止还没有成功。

It appears I need to add a trusted ca root certificate somehow, but have been unsuccessful so far in my attempts.

使用我们的ca root证书，我可以使用curl打开存储库。

I can hit the repository fine with curl using our ca root cert:

curl --cacert /etc/ssl/ca/ca.pem https://oururl.com:5000/v1/_ping

推荐答案

我想出了一个解决这个情况的解决方案，提出了这些来源的建议：

I came up with a work-around for the situation with suggestions from these sources:

https://github.com/docker/machine/issues/1799

https://github.com/docker/machine / issues / 1872

我登录到Minikube VM（ minikube ssh ），并编辑通过附加我自己的ca证书 /usr/local/etc/ssl/certs/ca-certificates.crt 文件。

I logged into the Minikube VM (minikube ssh), and edited the /usr/local/etc/ssl/certs/ca-certificates.crt file by appending my own ca cert.

然后我仍然在VM内重新启动docker守护程序： sudo /etc/init.d/docker restart

I then restarted the docker daemon while still within the VM: sudo /etc/init.d/docker restart

这不是非常优雅，因为如果我重新启动Minikube VM，我需要每次重复这些手动步骤。

This is not very elegant in that if I restart the Minikube VM, I need to repeat these manual steps each time.

另外，我还尝试在 DOCKER_OPTS - insecure-registry myurl.com:5000 选项c $ c>环境变量（重新启动的docker），但这对我来说不起作用。

As an alternative, I also attempted to set the --insecure-registry myurl.com:5000 option in the DOCKER_OPTS environment variable (restarted docker), but this didn't work for me.
