搭建e2e测试环境时的常见问题

搭建Dapr e2e测试环境时的常见问题

mongodb 部署失败

部署测试用的 mongodb 失败，长时间挂住，然后超时报错：

$ make setup-test-env-mongodb 
helm install dapr-mongodb bitnami/mongodb -f ./tests/config/mongodb_override.yaml --namespace dapr-tests --wait --timeout 5m0s

Error: INSTALLATION FAILED: timed out waiting for the condition
make: *** [tests/dapr_tests.mk:269: setup-test-env-mongodb] Error 1

pod 状态一直是 Pending：

$ k get pods -A
NAMESPACE     NAME                                     READY   STATUS    RESTARTS       AGE

pod的描述提示是 PersistentVolumeClaims 的问题：

$ k describe pods dapr-mongodb-77fdf49576-d9lx4 -n dapr-tests
Name:           dapr-mongodb-77fdf49576-d9lx4

pvc 也是 pending 状态：

k get pvc -n dapr-tests  
NAME           STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   AGE
dapr-mongodb   Pending                                                     22m

“StorageClass” 为空，所以失败。

sidecar 无法注入

一般是发生在重新安装 dapr 之后，主要原因是直接执行了 kubectl delete namespace dapr-tests ，而没有先执行 helm uninstall dapr -n dapr-tests

daprd启动时 sentry 证书报错

daprd启动时报错退出，日志如下：

time="2022-12-04T01:35:44.198741493Z" level=info msg="sending workload csr request to sentry" app_id=service-a instance=service-a-8bbd5bf88-fxc6k scope=dapr.runtime.grpc.internal type=log ver=edge

这是没有执行 make setup-disable-mtls 的原因。
