Ssl 如何在不提供证书的情况下使用etcdctl

大家好

也许这是一个非常愚蠢的问题，但我有一个CoreOS集群，在集群节点之间使用SSL。我已经在我的云配置中设置了舰队和etcd

fleetctl工作得很好。我不必提供任何证书，但当我使用etcdctl时，我会强制提供如下证书路径：

etcdctl --ca-file /home/core/etcd/certificates/ca.pem --cert-file /home/core/etcd/certificates/coreos.pem --key-file /home/core/etcd/certificates/coreos-key.pem --endpoint "https://10.129.1.226:2379" get /test/key

是否有一种方法可以配置etcd2，使etcdctl每次都不需要证书路径，如：

etcdctl get /test/key

我的云配置的一部分：

write_files:
  # tell etcd2 and fleet where our certificates are going to live:
  - path: /run/systemd/system/etcd2.service.d/30-certificates.conf
    permissions: 0644
    content: |
      [Service]
      # client environment variables
      Environment=ETCD_CA_FILE=/home/core/etcd/certificates/ca.pem
      Environment=ETCD_CERT_FILE=/home/core/etcd/certificates/coreos.pem
      Environment=ETCD_KEY_FILE=/home/core/etcd/certificates/coreos-key.pem
      # peer environment variables
      Environment=ETCD_PEER_CA_FILE=/home/core/etcd/certificates/ca.pem
      Environment=ETCD_PEER_CERT_FILE=/home/core/etcd/certificates/coreos.pem
      Environment=ETCD_PEER_KEY_FILE=/home/core/etcd/certificates/coreos-key.pem

根据该工具的README.md，您可以为客户端设置环境变量

您可以测试它：

1：确认它不工作

core@sylvana-coreos ~/docker $ etcdctl --endpoint "https://10.129.1.226:2379" ls /test
Error:  client: etcd cluster is unavailable or misconfigured
error #0: x509: certificate signed by unknown authority

2：导出正确的环境变量

export ETCDCTL_CA_FILE=/your/path/to/ca.pem
export ETCDCTL_CERT_FILE=/your/path/to/cert.pem
export ETCDCTL_KEY_FILE=/your/path/to/key.pem

3：验证它是否正常工作

core@sylvana-coreos ~/docker $ etcdctl --endpoint "https://10.129.1.226:2379" ls /test
/test/key
