ansible vs docker

Create ansible and manage container nodes based on DockerScenario: When learning conditions are limited, you can complete Docker and ansible learning with a single VMFIX: Create a custom image and build multiple ansible containers first.Of course, this method is suitable for other similar scenarios.VMS Environment:

the client needs to give the explicit execution file (YML), does not have the clear stipulation to the file storage location, Saltstack need to provide the host information on the command line, When you push a file (SLS) in the directory provided in the configuration file, the pushed file must also be in this directory.These are some of my personal views, the following start the actual operationEnvironment Introduction:Centos 6.5Ansible 2.3.0Docker 1.7.1Http 2.4.6-67One.

Do not reprint advanced playbook without written permission Finding files with variablesAll modules can take variables as part of their arguments by dereferencing themwith {{ and }} . You can use this to load a particular file based on a variable.For example, you might want to select a different config file for NRPE (a Nagioscheck daemon) based on the architecture in use. Here is how that would look:---#1- name: Configure NRPE for the right architecture#2hosts: ansibletest#3user: root#4tasks:#5
