The Vagrantfile tells Vagrant how to configure your virtual machines. Create Vagrant project files Create Vagrantfile Thus we have a project directory name of centos7-docker. The project is for Docker, so I include that in the name. We will be using a CentOS 7.2 Vagrant box, so I include centos7 in the Vagrant project name to differentiate it from a Centos 6 project. You should also use a helpful name for each Vagrant project directory you create. I keep my Vagrant projects in my ~/Development/Vagrant directory. Each Vagrant project should have its own directory. Read more here: vagrant-hostmanagerД«efore we get started, determine where you want to keep your Vagrant project files.

#Docker ip configuration mac

This plugin will automatically manage the /etc/hosts file on your local mac and in your virtual machines.

You should already have installed the vagrant-hostmanager plugin.

#Docker ip configuration upgrade

This plugin will keep the VirtualBox Guest Additions software current as you upgrade your kernel and/or VirtualBox versions. You should already have installed the vagrant-vbguest plugin.You should already have installed Vagrant 1.8.6.You should already have installed VirtualBox 5.1.x.You should already have downloaded the Docker HDP 2.5 Sandbox.

#Docker ip configuration install

While we are using Vagrant + Virtualbox, this process should work for any install of CentOS (Amazon, etc) with small changes because VirtualBox and related plugins are not needed. This tutorial will guide you through the process of installing Docker on CentOS 7 using Vagrant and modifying the configuration of Docker to move the location of and increase the size of Docker virtual machine image.

This will cause the loading process of the sandbox to fail. The default configuration of Docker on CentOS 7 limits your Docker virtual machine image to 10GB in size.

You can back-up your Consul datacenter using the consul snapshot command.If you are using Docker on CentOS 7, you may have run into issues importing the Docker version of the Hortonworks Sandbox for HDP 2.5. When a previously stopped server container is restarted using docker start, and it is configured to obtain a new IP, autopilot will add it back to the set of Raft peers with the same node-id and the new IP address, after which it can participate as a server again.

If the container running the currently-elected Consul server leader is stopped, a leader election will be triggered. server_stabilization_time should be sufficiently large (on the order of several seconds) so that unstable servers are not added to the datacenter until they stabilize.last_contact_threshold should be reasonably small, so that dead servers are removed quickly.cleanup_dead_servers must be set to true to make sure that a stopped container is removed from the datacenter.If you override them, make sure that the following settings are appropriate. Autopilot's default settings are already configured correctly. You can execute Consul commands directly inside of your Consul containers using docker exec.ДЄs long as there are enough servers in the datacenter to maintain quorum, Consul's autopilot feature will handle removing servers whose containers were stopped. You can access a containerized Consul datacenter in several different ways. You can also access your newly registered service from Consul's UI, В» Consul container maintenance operations В» Access containers WARNING: recursion requested but not availableД¬. flags: qr aa rd QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 2 >HEADER<<- opcode: QUERY, status: NOERROR, id: 47570
