使用Docker部署Mesos

部署环境

• 宿主机： macOS Sierra 10.12.1
• VirtualBox： Version 5.1.8 r111374 (Qt5.5.1)
• Vagrant： 1.8.7
• Vagrant Box： CentOS/7

虚拟机启动环境

Vagrantfile内容如下：

$num_instances = 3
$vm_gui = false
$vm_memory = 1024
$vm_cpus = 1
$instance_name_prefix = "mesos"
$vb_cpuexecutioncap = 100

def vm_gui
  $vb_gui.nil? ? $vm_gui : $vb_gui
end

def vm_memory
  $vb_memory.nil? ? $vm_memory : $vb_memory
end

def vm_cpus
  $vb_cpus.nil? ? $vm_cpus : $vb_cpus
end

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"

  (1..$num_instances).each do |i|
    config.vm.define vm_name = "%s-%02d" % [$instance_name_prefix, i] do |config|
      config.vm.hostname = vm_name

      config.vm.provider :virtualbox do |vb|
        vb.gui = vm_gui
        vb.memory = vm_memory
        vb.cpus = vm_cpus
        vb.customize ["modifyvm", :id, "--cpuexecutioncap", "#{$vb_cpuexecutioncap}"]
      end

      ip = "172.20.201.#{i+100}"
      config.vm.network :private_network, ip: ip

      # config.vm.synced_folder "./data", "/vagrant_data"
    end
    config.vm.provision "shell", inline: <<-SHELL
      # apt-get update
      curl -s https://get.docker.com/ | sudo sh
    SHELL
  end
end

启动虚拟机

vagrant up

执行上述命令后，虚拟机在启动之后将自动安装最新版本Docker

ZooKeeper启动

只是为了测试，启单节点的ZooKeeper

docker run --name zookeeper 
  --restart always 
  -d 
  -p 2181:2181 
  zookeeper

master安装

# 登录mesos-01:
vagrant ssh mesos-01

# 启动Docker
sudo systemctl enable docker && systemctl restart docker

启动Master

docker run -d --net=host 
  --name mesos_master 
  -e MESOS_PORT=5050

  --ip=172.20.201.101 
  --advertise_ip=172.20.201.101

启动slave

docker run -d --net=host --privileged 
  --name mesos_slave 
  -e MESOS_PORT=5051 
  -e MESOS_MASTER=zk://172.20.201.101:2181/mesos

  mesosphere/mesos-slave:1.1.0-2.0.107.ubuntu1404 
  --ip=172.20.201.101 
  --launcher=posix

启动marathon

docker run -d --net=host --privileged 
  --name mesos_marathon 
  mesosphere/marathon:latest 
  --master zk://172.20.201.101:2181/mesos 
  --zk zk://172.20.201.101:2181/marathon 
  --http_port 8080 
  --http_address 172.20.201.101 

安装其他节点

docker run -d --net=host --privileged 
  --name mesos_slave 
  -e MESOS_PORT=5051 
  -e MESOS_MASTER=zk://172.20.201.101:2181/mesos 
  -e MESOS_SWITCH_USER=0 
  -e MESOS_CONTAINERIZERS=docker,mesos
