现在你可以这样做：

kubectl get pods -l 'environment in (production, qa)'

https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#list-and-watch-filtering

在您的案例中不支持OR。
您可以尝试基于集合的标签选择器。https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#resources-that-support-set-based-requirements

允许的关键字是=, ==, !=, in, notin, exists(only the key identifier)。==和=是同义词。in可以用于OR运算。

如果可以使用jq，请尝试以下操作：

kubectl get nodes --output=json \
  | jq --raw-output '.items[].metadata | select (.labels."node-role.kubernetes.io/master" == "" or .labels."node-role.kubernetes.io/control-plane" == "") | .name'

或者使用go-template，不使用外部工具：

kubectl get nodes -o go-template='{{range $item := .items}}{{range $taint := $item.spec.taints}}{{if and ( or ( eq $taint.key "node-role.kubernetes.io/master") (eq $taint.key "node-role.kubernetes.io/control-plane") ) (eq $taint.effect "NoSchedule")}}{{printf "%s\n" $item.metadata.name}}{{end}}{{end}}{{end}}'

您可以使用“&&”将结果组合为伪OR

kubectl get pods -l="postgres-operator.crunchydata.com/control-plane" --no-headers -o name **&&** kubectl get pods -l="postgres-operator.crunchydata.com/cluster" --no-headers -o name

下面是一个合并结果并获取所有列的方法。
它从两个结果中获取pod的名称，并使用它们来获得单个结果。

echo $(kubectl get pods -l="postgres-operator.crunchydata.com/control-plane" --no-headers -o name && kubectl get pods -l="postgres-operator.crunchydata.com/cluster" --no-headers -o name) | xargs kubectl get
