To do this, we will add some parameters to the “Check for the file” task: - name: Check for the file file: path: "/tmp/john" state: file register: my_file until: my_file is succeeded retries: 2 delay: 1. If your intention is to create a new file if it is not present on the remote servers, then you should use the file module. ansible-cmdb is a shell wrapper script that tries its best to find the correct Python binary to use and the proper location of the ansible-cmdb. ssh/config file (create it if it does not exist): Save and exit. For example, the following will create a role directory structure called test-role-1 in the current working directory: Ansible and LXC Containers. We can use a regular expression to apply search conditions while working with the Lineinfile module. Excerpts from Kavin Kankeshwar's message of 19:49:25 -0400: > Yes, Even i thought it would, only replace not add. Inside host_vars we will create a new file with the same name as of the server. To simply check if "any" nfs mount exists, you cannot use the mount module. Example: - name: add services blockinfile: state: present insertafter: EOF dest: /etc/services marker: "" content: | line 1 line 2 line 3 Owner should not be kept between different hosts. blockinfile if you want to insert/update/remove a block of lines in a file. Now that you have a containerized deployment of AWX with PowerShell (see part 1 ), you can start to leverage the additional capabilities it provides within your Ansible Playbooks. blockinfile is a native, idempotent module to ensure a specified set of lines is present (absent) in a file. This rule is not enabled by default and was inspired by Zuul execution policy. This line will be put at the bottom of the file, unless otherwise specified. If regular expressions are passed to both regexp and insertbefore, insertbefore is only honored if no match for regexp is found. The same goes for check ing if a file does exist and only executing the action if it exists. This adds multiple lines each run, you should check if line non-existant or not the same before add. We can then evaluate that variable: - hosts: localhost user: engonzal connection: local tasks: - name: Check if /tmp exists stat: path: /tmp register: stat_tmp. By default, roles can also only be added as a dependency once - if another role also lists it as a dependency it will not be run again. 
This module will insert/update/remove a block of multi-line text surrounded by customizable marker lines. In our case we want it at the top because otherwise chruby will not be loaded properly when.
This is a playbook for ansible - ssh_keyscan. If you need to add a line and that particular line is NOT present anywhere in the file, then you can use the lineinfile module for this scenario. If the line exists in the file it won't be added again, if it doesn't exist it'll be added at the bottom. Here the first task will be executed only when foo variable is defined. Oftentimes, Ansible plays contain various sets of variables. If the file exists, however, we’ll show a message using the debug module. regex is optional and when blank, it won’t be included in the Ansible script this allows arbitrary additions to files. 10 El Capitan SUMMARY Lineinfile module with create=yes fails if the file is. They use a file with 4 lines and insert a line before and after those lines. The easiest way to check if a file exists using Ansible is with the stat module. using maybe existing lines in the file or maybe placeholder comments? The line ListenAddress 1. 
builtin by default: Line denoting the end of the printed statement.
results | map (attribute='stdout') If we put this back into your specific template able to give an output for any given host, this would give:
It is possible to set variables at the command line using the -extra-vars argument. This means that we need to use the /bin/bash executable (as the default shell ansible uses is /bin/sh, which does not support the pipefail option). ISSUE TYPE Bug Report ANSIBLE VERSION ansible 2. ansible – insert after only if the pattern exists and the new insert is not there. 
1 or will add new line if it does not exist This module ensures a particular line is in a file, or replace an existing line.Ansible insert line if not exists An example is shown below.
