k8s记录-ca证书制作(二)
作者:互联网
1)下载cfssl
#!/bin/bash wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64 wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64 chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 cfssl-certinfo_linux-amd64 mv cfssl_linux-amd64 /usr/local/bin/cfssl mv cfssljson_linux-amd64 /usr/local/bin/cfssljson mv cfssl-certinfo_linux-amd64 /usr/bin/cfssl-certinfo
2)制作etcd证书
#!/bin/bash #创建ETCD CA证书 cat << EOF | tee ca-config.json { "signing": { "default": { "expiry": "87600h" }, "profiles": { "www": { "expiry": "87600h", "usages": [ "signing", "key encipherment", "server auth", "client auth" ] } } } } EOF # 创建 ETCD CA 配置文件 cat << EOF | tee ca-csr.json { "CN": "etcd CA", "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "Shenzhen", "ST": "Shenzhen" } ] } EOF # 创建 ETCD Server 证书(注意更改host字段) cat << EOF | tee server-csr.json { "CN": "etcd", "hosts": [ "192.168.0.1", "192.168.0.2", "192.168.0.3" ], "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "Shenzhen", "ST": "Shenzhen" } ] } EOF # 生成 ETCD CA 证书和私钥 cfssl gencert -initca ca-csr.json | cfssljson -bare ca - cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=www server-csr.json | cfssljson -bare server
3)制作kubernetes证书
#!/bin/bash cat << EOF | tee ca-config.json { "signing": { "default": { "expiry": "87600h" }, "profiles": { "kubernetes": { "expiry": "87600h", "usages": [ "signing", "key encipherment", "server auth", "client auth" ] } } } } EOF cat << EOF | tee ca-csr.json { "CN": "kubernetes", "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "Shenzhen", "ST": "Shenzhen", "O": "k8s", "OU": "System" } ] } EOF # 生成 kubernetes CA 证书和私钥 cfssl gencert -initca ca-csr.json | cfssljson -bare ca - # 生成API_SERVER证书 (注意修改host部分) cat << EOF | tee server-csr.json { "CN": "kubernetes", "hosts": [ "10.1.0.1", "127.0.0.1", "192.168.0.1", "192.168.0.2", "192.168.0.3", "kubernetes", "kubernetes.default", "kubernetes.default.svc", "kubernetes.default.svc.cluster", "kubernetes.default.svc.cluster.local" ], "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "Shenzhen", "ST": "Shenzhen", "O": "k8s", "OU": "System" } ] } EOF cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=kubernetes server-csr.json | cfssljson -bare server # 创建 Kubernetes Proxy 证书 cat << EOF | tee kube-proxy-csr.json { "CN": "system:kube-proxy", "hosts": [], "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "Shenzhen", "ST": "Shenzhen", "O": "k8s", "OU": "System" } ] } EOF cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=kubernetes kube-proxy-csr.json | cfssljson -bare kube-proxy
