开发方式的变化：docker-compose 迁移到 minikube

发布于：2022-03-16 09:46:01  栏目：技术文档

使用 kompose 转义

下载安装 kompose：地址

有各种各样的版本供你选择，总有一款适合你

注意：新版本的 kompose 砍掉了 up 和 down 两个子命令，以前很多关于 kompose 把 docker-compose 项目直接迁移到 k8s 平台的教程都没有办法使用了

具体情况参考：如何解决 unknown command “up” for “kompose”

输入 kompose convert

使用

kubectl apply -f authentication-service-deployment.yaml,http-api-service-deployment.yaml,add-service-deployment.yaml

kubectl apply -f add-service-service.yaml,authentication-service-service.yaml,http-api-service-service.yaml

kubectl get pods -A

minikube image load ponponon/test-nameko-for-rabbitmq:1.0.1

minikube ssh

docker@minikube:~$ docker image ls
