我试图运行ansible-playbook并得到以下异常:
TASK [deploy aws auth configmap] ***********************************************
task path: /Kubernetes-in-Production-Best-Practices/Chapter04/ansible/tasks/aws-auth.yaml:1
The full traceback is:

下面是返回异常的命令:
ansible-playbook -i
../../inventories/packtclusters/
-e "worker_iam_role_arn=$(terraform output worker_iam_role_arn)
cluster_name=$(terraform output cluster_full_name)
aws_default_region=$(terraform output aws_region)"
../../cluster.yaml
这是"aw -auth.yaml"发生异常的文件:
- name: deploy aws auth configmap
k8s:

kubeconfig: "{{ k8s_kubeconfig }}"
state: "{{ k8s_manifests_state }}"

我终于找到问题所在了。似乎你不能在MacOS命令行中使用$()子命令。
如果我替换这个:
ansible-playbook -i
../../inventories/packtclusters/
-e "worker_iam_role_arn=$(terraform output worker_iam_role_arn)
cluster_name=$(terraform output cluster_full_name)
aws_default_region=$(terraform output aws_region)"
../../cluster.yaml -vvv
与这个:
ansible-playbook -i
../../inventories/packtclusters/
-e "worker_iam_role_arn=test
cluster_name=test
aws_default_region=test"
../../cluster.yaml -vvv
那么就可以了
它实际上抛出了另一个异常，但这是因为测试参数。
注:因此，在解析$(terraform output cluster_full_name)子命令后，转义#x001b字符实际上出现在命令行中，但是可见的调试输出错误地指向错误的文件，这使我感到困惑并将我引导到错误的路径。
