QUESTION
I have a requirement where I need to check for a file on the puppet master and copy it to the agent only if it is not empty.
I have the following so far:
...ANSWER
Answered 2020-Dec-17 at 02:50You cannot use an Exec resource to perform the check, because you need to perform the evaluation during catalog building, and resources are not applied until after the catalog is built. Moreover, the test command tests for the existence of a the specified path. It does not know about URLs, and even if it did, it would be unlikely to recognize or handle the puppet: URL scheme. Furthermore, there is no association whatever between resource titles and variable names.
To gather data at catalog building time, you're looking for a puppet function. It is not that hard to add your own custom function to Puppet, but you don't need that for your case -- the built-in file() function will serve your purpose. It might look something like this:
QUESTION
So for a hobby project of mine, I would like to create an application that translates an HTTP call and request between two services.
The application does that based on a configuration that can be set by the user. The idea is that the application listens to an incoming API call translates the call and then forwards it.
Then the application waits for a response then translates the response and sends it back to the caller.
A translation can be as simple as renaming a field value in a body object or replace a header field to the body.
I think a translation should begin with mapping the correct URL so here is an example of what I was thinking of a configuration should look like:
...ANSWER
Answered 2020-Nov-10 at 11:42I have done something sort-of-similar in a different context (generate code from an input specification), so I will provide an outline of what I did to provide some food for thought. I used Config4* (disclosure: I developed that). If the approach I describe below is of interest to you, then I suggest you read Chapters 2 and 3 of the Config4* Getting Started Guide to get an overview of the Config4* syntax and API. Alternatively, express the concepts below in a different configuration syntax, such as XML.
Config4* is a configuration syntax, and the subset of syntax relevant to this discussion is as follows:
QUESTION
I have written separate playbooks for tomcat deployment on both Ubuntu and Linux as well, instead of mentioning **
when: ansible_distribution == 'Ubuntu'
**in every line in the playbook, i want to run the whole playbook only when this condition meets.
This is my code
...ANSWER
Answered 2020-Feb-10 at 14:44Q: "I want to run the playbook only on the hosts based on the ansible_distribution."
A: It's not possible to include a playbook. This would run the playbooks recursively.
Only import of a playbook is available. Moreover import_playbook is not a task. It's simply a tool to modularize large playbooks with multiple plays.
Ansible conditionals do not apply to import_playbook the same way as they do not apply to playbooks.
Instead, it is possible to create a group that will be used in the playbook.

Install xenadu
Install Xenadu on something other than your target machine (like your laptop): curl -L https://github.com/iandennismiller/xenadu/tarball/master -o xenadu.tgz tar xvfz xenadu.tgz cd iandennismiller-xenadu* python setup.py install
Make a directory to store your configuration (we'll call it davidbowie, since that's the name of the machine). The files subdirectory will contain a copy of all the remotely managed files. mkdir davidbowie cd davidbowie mkdir files
Create a host definition file named davidbowie.py (or whatever you want, but again since this machine is named davidbowie, that's what I'm calling it) touch ./davidbowie.py chmod 755 ./davidbowie.py
Edit davidbowie.py, and paste this skeletal host definition file: #!/usr/bin/env python from Xenadu import XenaduConfig, Perm mapping = [ ['/etc/hosts', "hosts", Perm.root_644], ['/etc/network/interfaces', "interfaces", Perm.root_644], ] env = { 'ssh': { "user": "root", "address": "somewhere.example.com" } } XenaduConfig(globals())
Set the ssh address to point to your machine. env = { 'ssh': { "user": "root", "address": "elsewhere.example.com" } } Also, make sure you are familiar with ssh public key authentication. You need to log in as root in order for Xenadu to function correctly. If you are uncomfortable with being able to log in as root, then make sure your private key is password-protected, and use a ssh keychain manager.
Edit mapping to list the files you want to track. mapping is a python list, where each item in the list represents one file on the remote host. An item like ['/etc/network/interfaces', "interfaces", Perm.root_644] consists of 3 values: /etc/network/interfaces is the complete path of the file on the remote host interfaces is the local name of the file, which is in the ./files directory. Perm.root_644 is the permissions that file should have on the remote host (here, owner is root and permission is 644).
Grab all of those files from the remote host: ./davidbowie.py --getall This will automatically go through every item in mapping and download it to the local ./files directory.
The files are in ./files - save this configuration! git init; git commit -m 'initial davidbowie config'
