4.centos7 docker 安装

参考这个文档进行安装docker:

http://www.runoob.com/docker/centos-docker-install.html

开机启动

systemctl enable docker

查看是否启动状态

systemctl status docker

进入docker 镜像内部：

docker exec -it CONTAINER_ID bash

配置docker容器随宿主机启动

docker run -d --name elasticsearch --restart always -p 9200:9200 -p 9300:9300 -e discovery.type=single-node elasticsearch:6.6.1

Docker在mesos集群中的 相关设定

echo 'docker,mesos' > /etc/mesos-slave/containerizers

echo '5mins' > /etc/mesos-slave/executor_registration_timeout

 

必须进行此配置,否则会提示
