We use -limit to execute the command in only one server, though we use the hostgroup which contains two servers. First one and the last one is an Ansible ad-hoc command to check the availability of the file under the /tmpdirectory in mwiapp02server In the preceding screenshot, we have executed 3 commands.
delegate_to and the hosts along with mode in ansible-playbook, work together to make the remote execution (or) copy between remote nodes possible.
delegate_to It tells ansible, where the task (or) command should actually be executed. Either Synchronize pull or Synchronize push mode It represents the model of the Synchronize. Other two important lines in the file are as follows Hope the following image would make it clear. It represents the first element (or) server of the host group named "app" just like an array Run_once: yes fetch: src=/tmp/app01-to-app02.jar dest=buffer/ flat= yes when: " " Tasks: - name: Fetch the file from the mwiapp01 to master Here the master acts like a buffer where the files are temporarily stored and then transferred.Ĭonsider the following playbook which performs both these above-mentioned tasks. Step2: Push ( Copy) the file from the ansible master to the remote server ( destination) Step1: Fetch the file from the remote server (source) to the ansible master It is a two-step process when it comes to this method. It works well where our primary focus is to get the job done whatsoever the approach may be. Though, it is not the shortest path (or) beeline. This is the best and easiest option to transfer files between the remote nodes When you do not have SSH Key based Authentication enabled between the remote nodes. NO SSH Authentication required between remote nodes for this method Method1: Copy from app01 to app02 using fetch module Before we proceed, This is the infrastructure diagram of our setup.ĭo not get confused by the name Master. The requirement is to copy a file from mwiapp01 to mwiapp02. To get started, let us define some requirement ourselves so that, we could relate and be on the same page. Method2: Copy file between remote hosts using synchronize module. Method1: Copy files between remote hosts using fetch module. Method 2: Copy from app01 to app02 using synchronize module. Method1: Copy from app01 to app02 using fetch module. This is more like performing RSYNC with help of Ansible. Here is the Simple introduction to Ansible Fetch and Ansible Synchronize.Īnsible Fetch is to pull the files from the remote server to the control machine.Īnsible Synchronize is used to copy the files between remote servers (or) target hosts. While we are already aware of what is Ansible Copy module is used for. We are going to use some of the ansible modules like copy, fetch, synchronize to accomplish the requirement of copying the files between hosts in ansible. 
But we need something more when we want to copy the files between the remote hosts or to copy files between remote to remote. If you want to copy a file from an Ansible Control Master to remote hosts, the COPY (scp) module would be just fine.
When we want to copy files from one host to another host, in general, the first thing comes in our mind is SCP and ansible have a dedicated module for the same-named COPY In this post, we are going to discuss the two major options available to copy the files between remote servers or remote to remote. I wanted to execute rsync between remote hosts and copy files between remote hosts. I simply wanted to do make ansible rsync. Every article I went and read was giving me suggestions but nothing practical.
