makefile中的设置环境

Question

我正在尝试在 make 中导出一个环境变量，以便在下一行中使用。我按照这里的建议做 Setting environment variables in a makefile.

eks-apps:
    export KUBECONFIG=$(CURDIR)/terraform/kubernetes/cluster/$(shell ls terraform/kubernetes/cluster/ | grep kubeconfig)
    kubectl get all

但是它没有在 kubectl 命令中使用那个 kubeconfig。我错过了什么？

Answer 1

配方中的每一行都将在新的 shell 中执行。因此，您必须对所有命令使用一个 shell：

eks-apps:
    ( \
    export KUBECONFIG=$(CURDIR)/terraform/kubernetes/cluster/$(shell ls terraform/kubernetes/cluster/ | grep kubeconfig); \
    kubectl get all \
    )

来自您链接到的答案：

Please note: this implies that setting shell variables and invoking shell commands such as cd that set a context local to each process will not affect the following lines in the recipe.2 If you want to use cd to affect the next statement, put both statements in a single recipe line
