Tips for managing Sitecore containers

In this post, I will show you some useful commands and tips for managing your Sitecore containers, images and other docker resources that get created when standing up your containers. The Docker documentation is awesome but it is fairly extensive so I’ll cover some useful commands you should be familiar with.

PS> docker container ls – lists running containers by default, you need to use -a flag to list all containers not just running containers. You can use -f flag to filter containers.

PS> docker container ls -f “name=93x*”

If you want to see the most recently created use -l flag.

How to move Sitecore container images to an Azure Registry

If you have built your Sitecore container images and they reside locally and you want to share them with your team the recommended approach is a private registry and there are a few services available. However, Azure Container Registry (ACR) allows you to store docker images in repositories and can take advantage of the azure pipelines to automatically rebuild these images when they need to be updated. In this post, I will show you how to push your local images to a private ACR. This also works if you need to move your images from one private registry to another.

Running Windows and Linux Containers Simultaneously

If you are running Sitecore in a container then you’ve most likely switched Docker desktop to Windows container mode. But what if you want to run a Linux container simultaneously? For example, you might want to fire up, JMeter and Grafana on Linux containers. It turns out this is possible in your local development environment and is fairly straightforward.

docker-compose up is music to one’s Sitecore ear!

Don’t worry this is not another post about running Sitecore in a container! No this is a post about getting the Sitecore HabitatHome demo solution up and running quickly and I mean quickly without too much effort. I just happen to use docker in the process. HabitatHome is a solution built using SXA on Sitecore XP following Helix principles. It is extremely useful if you need to showcase SXA capabilities to an existing or a potential new customer.

This is where my good friend Andy Uzick found himself a few weeks ago but had already started down the path of standing up the SXA HabitatHome demo on a temporary Azure PAAS instance not using docker. I thought with docker surely this would be much easier.

Modifying Rendering Parameters with Sitecore Powershell

Okay, so we all know the difference between Renderings and Final Renderings right? Final renderings were introduced in Sitecore 8 to make it possible to have different layouts for the various language and versions of an Item. Awesome!!

  • __Renderings – a shared field where you specify the common layout for all languages and versions of the item.
  • __Final Renderings – a versioned field where you specify individual layouts for languages and versions of the item.

I ran into an issue where I needed to modify the __Final Renderings for specific templates. A parameter of a component for a specific language in use on a site, needed to be updated. Continue reading

Capture & Monitor JMeter metrics in real-time with InfluxDB & Grafana

The JMeter GUI is great for creating and debugging test plans, however, as I have mentioned in a previous post it is not recommended for running your actual test plan. JMeter is simply not designed to produce high loads in GUI mode, as it can consume a lot of resources and potential produce unreliable load test results. While it is recommended you run your actual test in CLI mode, this means you have to wait until the test is complete before you can see the results. While this might be okay for short tests but for longer running soak tests you might want to examine the results while the test is running. In this post, I will show you how this can be achieved using InfluxDB and Grafana.

The Tools

InfluxDB is a time-series database built for high-performance handling of time-stamped data.  JMeter provides a backend listener InfluxdbBackendListenerClient to write the data to InfluxDB. Grafana is an open-source metric analytics and visualization suite. It is most commonly used for visualizing time series data for infrastructure and application analytics. Continue reading

Nicely packaged Sitecore Items

Okay, so we all love and appreciate something that has been packaged up nicely. There are some really useful features built into Sitecore package designer that can make a huge difference in the packages we create and even save us time.

Saving & Opening Existing Packages

If you have spent time creating a package you should save it so that if you need to modify it later, you can. After you have generated and installed the package but discover you have forgotten to include something rather than go through the pain of creating a new package you can simply open the existing package. Opening a package allows you to modify the items contained in the package or add new items. This is a no-brainer. Continue reading
