k8s运行oracle
2、创建.yaml文件K8S安装Oracle11g备注:端口1521 -> 315214、进入pod问题:解决方案:需等待大约10分钟,正在拉取镜像5、查看pod6、查看日志7、删除pod问题:删除后又自己重启了解决方案1:不行!解决方案2:删除命名空间.........

1、创建命名空间
alias k='kubectl'
k create ns oracle-server
k get ns
2、创建.yaml文件
K8S安装Oracle11g

3、运行pod
k apply -f oracle.yaml
alias ko='k -n oracle-server'
4、进入pod
问题:
Error from server (BadRequest): container "oracle-server" in pod "oracle-server" is waiting to start: trying and failing to pull image.
Normal Pulling 3m5s kubelet Pulling image "registry.cn-hangzhou.aliyuncs.com/liyusoft/tool-oracle:v1.0.1"
解决方案:
需等待大约10分钟,正在拉取镜像
ko get pod

6、查看日志
ko logs -f oracle-server-56c657455b-7kfj6
7、删除pod
ko delete pod oracle-server-56c657455b-7kfj6
pod "oracle-server-56c657455b-7kfj6" deleted
问题:删除后又自己重启了
ko get deployments

解决方案1:不行!
ko delete pod oracle-server-56c657455b-lffbf --force --grace-period=0
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "oracle-server-56c657455b-lffbf" force deleted
ko get pod

ko get pod
Error from server (Timeout): the server was unable to return a response in the time allotted, but may still be processing the request (get pods)
You have new mail in /var/spool/mail/root
ko get pod

解决方案2:删除命名空间
ko delete --all pods
Error from server (Timeout): the server was unable to return a response in the time allotted, but may still be processing the request (get pods)
kubectl delete ns oracle-server
namespace "oracle-server" deleted
