REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: etcd
CHART VERSION: 8.5.11
APP VERSION: 3.5.6
** Please be patient while the chart is being deployed **
etcd can be accessed via port 2379 on the following DNS name from within your cluster:
my-release-etcd.default.svc.cluster.local
To create a pod that you can use as a etcd client run the following command:
kubectl run my-release-etcd-client --restart='Never' --image docker.io/bitnami/etcd:3.5.6-debian-11-r10 --env ROOT_PASSWORD=$(kubectl get secret --namespace default my-release-etcd -o jsonpath="{.data.etcd-root-password}" | base64 -d) --env ETCDCTL_ENDPOINTS="my-release-etcd.default.svc.cluster.local:2379" --namespace default --command -- sleep infinity
Then, you can set/get a key using the commands below:
kubectl exec --namespace default -it my-release-etcd-client -- bash
etcdctl --user root:$ROOT_PASSWORD put /message Hello
etcdctl --user root:$ROOT_PASSWORD get /message
To connect to your etcd server from outside the cluster execute the following commands:
kubectl port-forward --namespace default svc/my-release-etcd 2379:2379 &
echo "etcd URL: http://127.0.0.1:2379"
* As rbac is enabled you should add the flag `--user root:$ETCD_ROOT_PASSWORD` to the etcdctl commands. Use the command below to export the password:
export ETCD_ROOT_PASSWORD=$(kubectl get secret --namespace default my-release-etcd -o jsonpath="{.data.etcd-root-password}" | base64 -d)
[root@arm download]# kubectl run my-release-etcd-client --restart='Never' --image docker.io/bitnami/etcd:3.5.6-debian-11-r10 --env ROOT_PASSWORD=$(kubectl get secret --namespace default my-release-etcd -o jsonpath="{.data.etcd-root-password}" | base64 -d) --env ETCDCTL_ENDPOINTS="my-release-etcd.default.svc.cluster.local:2379" --namespace default --command -- sleep infinity

## 自己猜测应该是端口冲突，于是helm help , helm install -h 研究了一下
# 后面想到这个端口是pod内的，所以不会冲突，所以继续研究pv，pvc
|
然后阅读pv，pvc的官方文档发现:
静态制备
集群管理员创建若干 PV 卷。这些卷对象带有真实存储的细节信息， 并且对集群用户可用（可见）。PV 卷对象存在于 Kubernetes API 中，可供用户消费（使用）。
动态制备
如果管理员所创建的所有静态 PV 卷都无法与用户的 PersistentVolumeClaim 匹配， 集群可以尝试为该 PVC 申领动态制备一个存储卷。 这一制备操作是基于 StorageClass 来实现的：PVC 申领必须请求某个 存储类， 同时集群管理员必须已经创建并配置了该类，这样动态制备卷的动作才会发生。 如果 PVC 申领指定存储类为 ""，则相当于为自身禁止使用动态制备的卷。
加上看到pvc的详细信息，确实是StorageClass为空，所以只能手动制备PV存储卷先了

NAME: my-release
LAST DEPLOYED: Sun Jan 8 19:43:49 2023
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: etcd
CHART VERSION: 8.5.11
APP VERSION: 3.5.6
** Please be patient while the chart is being deployed **
etcd can be accessed via port 2379 on the following DNS name from within your cluster:
my-release-etcd.default.svc.cluster.local
To create a pod that you can use as a etcd client run the following command:
kubectl run my-release-etcd-client --restart='Never' --image docker.io/bitnami/etcd:3.5.6-debian-11-r10 --env ROOT_PASSWORD=$(kubectl get secret --namespace default my-release-etcd -o jsonpath="{.data.etcd-root-password}" | base64 -d) --env ETCDCTL_ENDPOINTS="my-release-etcd.default.svc.cluster.local:2379" --namespace default --command -- sleep infinity
Then, you can set/get a key using the commands below:
kubectl exec --namespace default -it my-release-etcd-client -- bash
etcdctl --user root:$ROOT_PASSWORD put /message Hello
etcdctl --user root:$ROOT_PASSWORD get /message
To connect to your etcd server from outside the cluster execute the following commands:
kubectl port-forward --namespace default svc/my-release-etcd 2379:2379 &
echo "etcd URL: http://127.0.0.1:2379"
* As rbac is enabled you should add the flag `--user root:$ETCD_ROOT_PASSWORD` to the etcdctl commands. Use the command below to export the password:
export ETCD_ROOT_PASSWORD=$(kubectl get secret --namespace default my-release-etcd -o jsonpath="{.data.etcd-root-password}" | base64 -d)

发现得到同样的错误，然后去网上查找发现一个issue: Running the container fails with ’exec /opt/bitnami/scripts/zookeeper/entrypoint.sh: exec format error’
I’m afraid we currently don’t have support for ARM architecture in our containers. It’s something that we have in our backlog, but there are no immediate plans to work on it.
As soon as there are news, we will let you know.
原来bitnami不支持ARM架构的服务器…….我吐血了
