嘿,所有,

也许这是一个非常愚蠢的问题,但是我在集群节点之间有一个带SSL的CoreOS集群。我已经在我的云配置中设置了Fleet和etcd。

Flecttl工作得很好。我不必提供任何证书,但是当我使用etcdctl时,我被迫提供了这样的证书路径:

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


有没有一种可以这样配置etcd2的方式,使得etcdctl不需要每次都需要证书路径,例如:

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


提前谢谢了。

最佳答案

根据etcdctl工具的README.md,可以为客户端设置环境变量。

您可以对其进行测试:

1:确认它不起作用

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

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