升级API网关Kong

2021-03-25
参考github上的dockerfile https://github.com/Kong/docker-kong/tree/master/centos ，在dockefile里面添加自定义的内容进行进行编译。本例中在官方的例子上安装了telnet、iproutes等软件包，同时为了实现网关的后续的应用程序认证鉴权，增加了graphql的lua扩展模块
准备dockerfile

docker build -t harbor.59iedu.com/fjhb/kong:2.3.2 .docker push harbor.59iedu.com/fjhb/kong:2.3.2更新运行中的docker
- 修改k8s的deployment文件，替换镜像版本后进行apply
- 涉及到版本升级，需要进入init-container wait-for-migrations，分别执行下列命令，否则proxy和ingress-controller无法成功启动
kong migrations upkong migrations finish
好知识，才能预见未来
