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:

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 wirbelsturm
This section brings you up to speed from zero to a running cluster. Here, we will show how to use the default cluster configuration of Wirbelsturm to deploy a Storm cluster locally on your host machine (e.g. your laptop). If you are deploying Wirbelsturm remotely -- such as on Amazon AWS -- the instructions are very similar. In the latter cases you should first read the respective sections (e.g. on deploying to AWS) further down in this document and then come back to this section because Wirbelsturm works 99% in the same way no matter to where you deploy.
Wirbelsturm depends on the following software packages on the host machine from which you run Wirbelsturm, i.e. the machine on which you execute commands such as vagrant up. So if you are running Wirbelsturm on your laptop, you must install those packages on that laptop.
Vagrant 1.7.2+
VirtualBox 4.3.x
Optional but recommended: GNU parallel. This step is only needed if you want to benefit from parallel provisioning via our deploy script to speed up deployments. If in doubt, do install parallel because ./deploy is superior to the standard vagrant up.
have a working Homebrew or MacPorts setup
have bash as their default shell
Verify the installation of Vagrant:. Note for Mac OS X users: To uninstall Vagrant run the uninstall.tool script that is included in the .dmg file.
Download version 1.7.2 of Vagrant for your OS and install accordingly.
Note for Mac OS X users: To uninstall VirtualBox run the VirtualBox_Uninstall.tool script that is included in the .dmg file.
Download a VirtualBox 4.3.x platform package for your OS and install accordingly.
Install parallel on the host machine:.
Clone this repository and then bootstrap Wirbelsturm:. The bootstrapping step will prepare the local environment of your host machine so that it can properly run Wirbelsturm. This includes, for instance, installing a compatible version of Ruby via rvm, required Ruby gems, Vagrant plugins and Vagrant boxes, as well as any Puppet modules that are included in Wirbelsturm out of the box (see Puppetfile).
