Writing Chef Target Mode Resources

Writing Chef Target Mode Resources After my previous blog posts, you might be tempted to write your own Chef custom resources which are compatible with Target Mode. Luckily, this is very easy - so this will be a short one.

Amazon Connect und die kleine Mailbox…

Amazon Connect und die kleine Mailbox… Amazon Connect ist als veröffentlichter Service zwar noch relativ jung, aber definitiv nicht mehr in den Kinderschuhen. Das cloudbasierte Contact Center von Amazon etabliert sich zunehmend, was auch wir - nicht zuletzt über steigende Projektzahlen - feststellen können. Dabei besticht es unter anderem durch seine offene Plattform und hohe Integrierbarkeit. Was fehlt - ist eine Mailbox!

Local Preprocessing in Target Mode

Local Preprocessing in Target Mode If you ever created configuration files with any automation system, you know that this involves a lot of templating. This is actually one of the most basic tasks that Chef performs and it is done using the template resource. With Chef’s Target Mode this currently is a bit more complicated.

Target Mode with Chef Server and Chef Automate

Target Mode with Chef Server and Chef Automate It is not sufficient to provision remote devices via Target Mode but we also want an overview of node attributes, run history and changed resources. In this post we have a look at how to connect agentless resources with central servers to give us the much-needed visibility.

Getting around circular CloudFormation Dependencies: S3-Event-Lambda-Role

Getting around circular CloudFormation dependencies Several posts complain about the inability of CloudFormation to apply a Lambda event function to an S3 Bucket with an dynamically generated name. The standard UseCase is an S3 Bucket with a Lambda event notification. In this special case the Bucket has a dynamically generated name. This cannot be done by pure CloudFormation! How to work around this circular depency? Let me show you an easy way:

Agentless Provisioning with Chef

Agentless Provisioning with Chef One of the main points of criticism about Chef I heard over the last few years has been the need to have an agent deployed at remote machines. Sometimes that is not desired, sometimes it is not even possible. Due to this, configuring remote machines has become the stronghold of other tools - but a new feature of Chef changes the landscape fundamentally.

Große Wolken - CloudFormation Makros

How to: CloudFormation Makro CloudFormation vermisst gegenüber Terraform einige Funktionen, die das Erstellen von Infrastruktur vereinfachen können. Das ist grundsätzlich korrekt, allerdings gibt es in CloudFormation die Möglichkeit, sich selber um den Einbau solcher Funktionen zu kümmern. Das geht mithilfe sogenannter CloudFormation Makros. CloudFormation Makros sind Funktionen, die wir per CloudFormation erstellen können und dann in weiteren CloudFormation Templates einbauen und verwenden können. Wir zeigen dies am Beispiel einer Count Funktion.

Deploying the Serverless Framework to AWS from Azure DevOps

Introduction Recently I worked on a project with the Serverless Framework which I really like. I used it do define a serverless application for a customer that runs their workloads mostly on AWS but uses Azure DevOps to build and deploy resources. This came about because they were already building lots of .Net applications and are therefore used to VSTS, the former name of Azure DevOps. After recovering from the initial shock of having to use an Azure tool to deploy resources to AWS I gave it a chance (well, I didn’t really have a choice in the matter).
