k8s 创建job 执行oc命令删除/操作宿主机内pod

本文主要是介绍k8s 创建job 执行oc命令删除/操作宿主机内pod，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

制作job 所使用的的容器 Dockerfile

FROM xxx.xxx.com/alpine:3.9
COPY glibd-2.23-r3.apk /opt/glibd-2.23-r3.apk
COPY ./ssh_config /etc/ssh/
COPY clock /etc/sysconfig/clockRUN echo "xxx.xxx.com/alpine/v3.9/main" >/etc/apk/repositories && \echo "xxx.xxx.com/alpine/v3.9/main" >/etc/apk/repositories && \apk add --no-cache sshpass openssh-client grep bash bash-doc bash-completion zip && \apk --allow-untrusted --force add /opt/glibc-2.23-r3.apk && \mkdir -p /root/.ssh && \rm /opt/glibc-2.23-r3.apk && \rm -rf /var/cache/apk/*COPY config /root/.ssh
copy delete_pod.sh \xxx.sh \/opt/

2.删除宿主机pod脚本

#!/bin/bashset -xif [ -f "/host/bin/oc_ori" ]; thenkubectl=/host/bin/oc_ori
elsekubectl=/host/bin/oc
fifunction check_kubectl() {echo "Info:check whether kubectl exists"for i in {1..20}; doif [ -f "$kubectl" ]; then return 0; else sleep10; fidoneecho "failed"return 1
}function delete_pod() {echo "get pod"names=`${kubectl} get deployment -n xxxxx-base | grep -i "ssssssxxxxx" | awk '{print $1}'`# 后续自己发挥
}
