我必须检查Kubernetes集群中节点的运行状况,所以为此,我使用这样的东西,输出:
$ kubectl get nodes
NAME STATUS AGE
ci-cluster-1-xpgwg744oc3y-minion-0 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-1 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-2 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-3 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-4 Ready 1d
我需要准备好数字节点,所以我需要做的就是计算就绪重合数与行数之间的关系,但是在将它分配给变量时它不会保留行尾。
有什么建议吗?

没关系,就像将它捕获到带引号的变量一样简单:
export output=$(kubectl get nodes)
echo "$output"
NAME STATUS AGE
ci-cluster-1-xpgwg744oc3y-minion-0 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-1 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-2 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-3 Ready 1d
ci-cluster-1-xpgwg744oc3y-minion-4 Ready 1d
