YAML配置文件管理资源实用技巧? 用run命令生成kubectl run --image=nginx my-deploy -o yaml --dry-run > my-deploy.yaml? 用get命令导出kubectl get my-deploy/nginx -o=yaml --export > my-deploy.yaml? Pod容器的字段拼写忘记了kubectl explain pods.spec.containers用run命令生成 --dry-run生成配置文件[root@mcwk8s03 demo]# kubectl run mcw-nginx-deployment --image=nginx --port=80 --replicas=3 --dry-run#执行部署的命令后面接--dry-run，不会进行部署，可以检查是否有语法错误kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubectl run --generator=run-pod/v1 or kubectl create instead.deployment.apps/mcw-nginx-deployment created (dry run)[root@mcwk8s03 demo]# kubectl get podNAMEREADYSTATUSRESTARTSAGEnginx-deployment-7fd6966748-mxg8p1/1Running036mnginx-deployment-7fd6966748-pgfgq1/1Running036mnginx-deployment-7fd6966748-wsfj41/1Running036m[root@mcwk8s03 demo]# kubectl get deployNAMEREADYUP-TO-DATEAVAILABLEAGEnginx-deployment3/33337m[root@mcwk8s03 demo]# [root@mcwk8s03 demo]# kubectl run mcw-nginx-deployment --image=nginx --port=80 --repli=3 --dry-run #如这条命令，副本数参数写错了就报错了Error: unknown flag: --repli
Examples:# Start a single instance of nginx.kubectl run nginx --image=nginx
--dry-run 不执行 -o指定输出格式，然后追加到文件中。这样可以生成yaml配置文件，我们就不需要去网上找模板了。将导出的模板多余的部分删除掉就行了。我们也可以获取到json格式的数据
