etcdctl3.5下载链接

bash 复制代码
1. 先通过上面链接下载gz包
 2. 解压
[root@k8s-master ~]# tar xf etcd-v3.5.11-linux-amd64.tar.gz
[root@k8s-master etcd-v3.5.11-linux-amd64]# ls
Documentation  etcd  etcdctl  etcdutl  README-etcdctl.md  README-etcdutl.md  README.md  READMEv2-etcdctl.md
3.将etcdctl命令拷贝至/usr/local/bin目录下，这样就可以直接通过命令行工具使用了
[root@k8s-master etcd-v3.5.11-linux-amd64]# cp etcdctl /usr/local/bin/
4.在/etc/profile文件最下面追加以下4行
export ETCDCTL_API=3
export ETCDCTL_CACERT=/etc/kubernetes/pki/etcd/ca.crt
export ETCDCTL_CERT=/etc/kubernetes/pki/etcd/peer.crt
export ETCDCTL_KEY=/etc/kubernetes/pki/etcd/peer.key
[root@k8s-master etcd-v3.5.11-linux-amd64]# source /etc/profile
5.此时ectdctl命令就可以使用了
#查看版本
[root@k8s-master etcd-v3.5.11-linux-amd64]# etcdctl version
etcdctl version: 3.5.11
API version: 3.5
#获取pods资源
[root@k8s-master etcd-v3.5.11-linux-amd64]# etcdctl get /registry/pods --prefix --keys-only=true
