问题描述
我正在脚本中使用kubectl来获取当前的GKE群集名称，如下所示:
I am using kubectl in a script to get the current GKE cluster name like so:
CURRENT_CLUSTER=$(kubectl run curl --rm --restart=Never -it --image=appropriate/curl -- -H "Metadata-Flavor: Google" http://metadata.google.internal/computeMetadata/v1/instance/attributes/cluster-name)
不幸的是kubect将pod "curl" deleted打印到标准输出，所以结果是这样的:
Unfortunately kubect prints pod "curl" deleted to standard output, so the result is this:
my-cluster-us-west1pod "curl" deleted
如何停止kubectl打印此字符串?
How can I stop kubectl from printing this string?
推荐答案
如果群集名称和不需要的文本之间有空格，则可以:
If there were a space between the cluster name and the unwanted text then you could use awk to take the first word of the output:
CURRENT_CLUSTER=$(kubectl run curl --rm --restart=Never -it --image=appropriate/curl -- -H "Metadata-Flavor: Google" http://metadata.google.internal/computeMetadata/v1/instance/attributes/cluster-name | awk '{print $1;}')
但是没有空格，因此必须以不同的方式删除它，例如使用 s删除"pod"及其后的所有内容:
But there isn't a space so it has to be removed differently, such as using sed to remove 'pod ' and anything after it:
CURRENT_CLUSTER=$(kubectl run curl --rm --restart=Never -it --image=appropriate/curl -- -H "Metadata-Flavor: Google" http://metadata.google.internal/computeMetadata/v1/instance/attributes/cluster-name | sed "s/pod .*//g")
