无法通过 Tekton 的入门。 TaskRun 实际上并未运行

Question

我在我的 Linux 机器上使用 minikube 完成了本教程的终点线：https://tekton.dev/docs/getting-started/。但出了点问题，我没有得到预期的

echo

结果。

为了跟踪 TaskRun 进度运行：

➜  TWOC tkn task start hello && sleep 5 &&  kubectl get pods && tkn taskrun list
TaskRun started: hello-run-rjd2l

In order to track the TaskRun progress run:
tkn taskrun logs hello-run-rjd2l -f -n default

Answer 1

此任务运行列表：

NAME              STARTED   DURATION   STATUS
hello-run-5f4qc   ---       ---        ---
hello-run-5zck9   ---       ---        ---
hello-run-8sdmx   ---       ---        ---

并且没有创建对应的 Pod 则表明您的 Pipeline Controller 无法正常工作。检查控制器的日志以查看是否存在任何相关问题，例如与

kubectl logs tekton-pipelines-controller-7c5494d584-d6gkn

。

日志中的此错误：

Kind=任务失败：发布“https://tekton-pipelines-webhook.tekton-pipelines.svc:443/?timeout=30s”：拨打 tcp 10.101.106.201:443：连接：连接被拒绝

表明存在一些连接问题。

当我按照指南在我的机器上使用 Minikube 时，它运行没有问题。

Answer 2

最后，Jonas 告诉我，我的 minikube 的内部网络存在错误，我们无法解决，我决定创建一个 GKE 集群，这使我能够成功通过教程

Answer 3

有时你只需要重新启动 minikube 即可。

minikube start
