Getting around mixed content errors when using Snaplogic XML Parser

We're doing a Snaplogic proof of concept and the UI is quite pretty so I thought I would write some blog posts about it. This will make a break from the normal boring badly spelled content I publish! Snaplogic works very well with JSON data in its pipelines but the integrations that we need to build make heavy use of XML. One solution is to use the XML Parser snap which will convert the XML into JSON. Unfortunately, the XML Parser failed for the first pipeline we tried in our POC!

My plans for a SAAS multi-tenant security microservice

I have been thinking a lot recently about how microservice based approaches can work for me in resolving many of the problems I encounter. The trouble is there is a tonne of information on the subject and working out a clear definition of a microservice is not easy. I needed to work out what I think a microservice actually is. (See https://code.metcarob.com/node/245). To do this I want to build an experimental microservice to see how the technical challenges pan out.

My Python WebApp Container Template

I am not an expert at building container images, but I do have some experiences. These ‘experiences’ have led me to build containers in a certain way. There are many practices and approaches I use to make the final container easy to use and robust. There are also different types of container that I aim to build. One type of container I need is one that hosts python (flask) based RESTful services and possibly a static web application. I have created a template to produce one of these and I will describe how I use it to create a new container here.

When suppliers use API's do organizations need to create CDM's?

Note: In this post I use the acronym CDM to mean “Canonical Data Model”.

I might be way behind the curve but I am constantly learning and have recently read up about Lean Software Development. My understanding of this is the principle that all steps/process/practices should be removed where they do not have benefit for the customer. I kind of knew this but hadn't read the formalization of it!

So what about CDM's? It’s a lot of work to create central API’s/CDM’s; can they be cut out?

How (and why) I put together my docker based Drupal website fronted by Kong running on a Swarm

My side project for the last two months has been putting together what has ended up being docker based website fronted by Kong. (With a docker image repository thrown in for good measure.) It’s been a bit of an odyssey to be honest. I didn’t start out meaning to create this monster; it was just supposed to be a Drupal site running on docker but as I worked out the development and maintenance processes around it little details made me gradually add complexity. It might be a bit of a monster but it is my monster it works well for me.

My first Snaplogic Pipeline!

While I wait for decision makers where I work to decide on whether to approve our recommendation of looking at a new integration platform I have been able to spend some time getting familiar with the Snaplogic iPaaS. Apart from Snaplogic's own site there isn't too much online discussing it so I thought I would share my first impressions.

Why am I writing a Blog?

I thought I would start my blog with a post about why I am writing it. At the very least it will help collect my thoughts together about how I plan and write posts. Not that I expect that anyone will read it. You see I am not an expert, and I don't plan to write about stuff I know well. This blog is going to be a place for me to put my thoughts, my ideas and my plans. Many many things I put here will be wrong! Even worse, I am a terrible communicator, terrible at writing and my spelling and grammar sucks more than you know. But, I am an idea machine.
