我试图在CoreOS beta（1192.2.0）上安装kubelet 1.4.5的kubernetes。“x509：由未知授权机构签名的证书”运行kubelet时
我使用的控制器和工人的稍作修改的版本从https://github.com/coreos/coreos-kubernetes/tree/master/multi-node/generic
所以一般安装脚本我用下面的bash脚本创建上的Gentoo Linux的许可证：
#!/bin/bash
export MASTER_HOST=coreos-2.tux-in.com
export K8S_SERVICE_IP=10.3.0.1
export WORKER_IP=10.79.218.3
export WORKER_FQDN=coreos-3.tux-in.com
openssl genrsa -out ca-key.pem 2048
openssl req -x509 -new -nodes -key ca-key.pem -days 10000 -out ca.pem -subj "/CN=kube-ca"
openssl genrsa -out apiserver-key.pem 2048
openssl req -new -key apiserver-key.pem -out apiserver.csr -subj "/CN=kube-apiserver" -config openssl.cnf
openssl x509 -req -in apiserver.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out apiserver.pem -days 365 -extensions v3_req -extfile openssl.cnf
openssl genrsa -out ${WORKER_FQDN}-worker-key.pem 2048
openssl req -new -key ${WORKER_FQDN}-worker-key.pem -out ${WORKER_FQDN}-worker.csr -subj "/CN=${WORKER_FQDN}" -config worker-openssl.cnf
openssl x509 -req -in ${WORKER_FQDN}-worker.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out ${WORKER_FQDN}-worker.pem -days 365 -extensions v3_req -extfile worker-openssl.cnf
openssl genrsa -out admin-key.pem 2048
openssl req -new -key admin-key.pem -out admin.csr -subj "/CN=kube-admin"
openssl x509 -req -in admin.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out admin.pem -days 365
echo done
这是openssl.cnf
[req]
req_extensions = v3_req
distinguished_name = req_distinguished_name
[req_distinguished_name]
[ v3_req ]
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names
[alt_names]
DNS.1 = coreos-2.tux-in.com
DNS.2 = coreos-3.tux-in.com
IP.1 = 10.3.0.1
IP.2 = 10.79.218.2
IP.3 = 10.79.218.3
，这是我worker-openssl.cnf
[req]
req_extensions = v3_req
distinguished_name = req_distinguished_name
[req_distinguished_name]
[ v3_req ]
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names
[alt_names]
IP.1 = 10.79.218.3
DNS.1 = coreos-3.tux-in.com
我控制器机是coreos-2.tux-in.com解析为局域网IP 10.79.218.2
我的工人的机器是coreos-3.tux-in.com解析为局域网IP 10.79.218.3
它创建许可证就好了。但是当我使用它们和主计算机上安装控制器剧本，我看到，当我运行journalctl -xef -u kubelet，我注意到以下消息：

你还可以看看其他Kubernetes组件的日志吗？尤其是主人apiserver。如果我正确地看到它，您应该能够使用'docker ps'查看组件，并使用'docker logs'显示它们。 –

使用火箭。而且我没有每个容器的具体日志 – ufk
