docker搭建spark集群

借鉴&＃xff1a;https://blog.csdn.net/u013705066/article/details/80030732
下面这个例子让我感受到docker的便捷和强大。
两行命令搭建spark集群&＃xff1a;

1.准备一个docker-compose.yml配置文件&＃xff0c;描述集群结构及必要参数


2.执行命令拉取spark镜像到本地(该步骤可省略)&＃xff1a;

3.在配置文件所在目录启动

4.查看启动结果





 浏览器访问&＃xff1a;http:/{docker_host}:50070











附docker基本命令&＃xff1a;

docker build -t friendlyhello . # Create image using this directory&＃39;s Dockerfile
docker run -p 4000:80 friendlyhello # Run "friendlyhello" mapping port 4000 to 80 docker run -d -p 4000:80 friendlyhello # Same thing, but in detached mode docker container ls # List all running containers docker container ls -a # List all containers, even those not running docker container stop <hash> # Gracefully stop the specified container docker container kill <hash> # Force shutdown of the specified container docker container rm <hash> # Remove specified container from this machine docker container rm $(docker container ls -a -q) # Remove all containers docker image ls -a # List all images on this machine docker image rm # Remove specified image from this machine docker image rm $(docker image ls -a -q) # Remove all images from this machine docker login # Log in this CLI session using your Docker credentials docker tag username/repository:tag # Tag for upload to registry docker push username/repository:tag # Upload tagged image to registry docker run username/repository:tag # Run image from a registry
