安装Docker

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum -y install docker-ce-19.03.5
systemctl enable docker && systemctl start docker

部署dosgame

docker run -d --name dosgame -p 262:262 oldiy/dosgame-web-docker:latest

高级启动（可选）

需要先将容器内/app/static/games拷贝出来
docker run -d --name dosgame -p 262:262 -v <host/file>:/app/static/games oldiy/dosgame-web-docker:latest

基础环境:

  • Linux
  • Docker

命令：

docker run --rm -dit --name excalidraw -p 5000:80 excalidraw/excalidraw:latest
#请替换5000为你所在主机要暴露该服务web页面的端口

***需要修改nodePort端口为你自己的，如果你用其他方式暴露则忽略***

- 3

kubectl create ns excalidraw

创建excalidraw namespace

- 4

kubectl apply -f excalideaw-deployment.yaml -n excalidraw

部署excalidraw 工作负载

如你所见，本站运行在Kubernetes集群中，当某个节点有问题或者需要重启时，依然能提供正常的访问能力，并且可以自动恢复，直接进行维护即可，得益于Kubernetes的调度，让本站的容灾能力得到提升，下面是yaml文件

需要修改的地方

  • storageClassName ##修改为你自己的存储类名
  • storage #持久化存储空间的大小
  • nodePort #暴露在宿主机上的端口

部署

kubectl create ns typecho #创建namespace命名空间
kubectl apply -f typecho.yaml -n typecho
