A fix for Sitecore's developer SolrCloud containers failing to find ZooKeeper

This fix may help you resolve startup issues with the internal ZooKeeper instance

A while back I wrote up some notes on a problem some people were seeing with Sitecore's SolrCloud developer container that I'd been unable to fix. It was the worst sort of technical problem, happening irregularly on some computers, but never rearing its head on others. So it's taken me a while to get around to coming up with a fix for this. But if you've suffered from the problems described in my previous post, this is an option for you:

A quick trick for exploring job images

It can be tricky to explore a container which doesn't run for long

Most of the time when I want to explore the filesystem of a Sitecore container, it's pretty easy. I can use Visual Studio's container browser. But that only works when a container is running - and if it's based on a job image this may be a very brief window - too brief to find and explore the file in question. So what can I do?

Docker Desktop v4.14/v4.15/v4.16 breaks Windows Containers?

Do you have issues with the \\.\pipe\docker_engine_windows named pipe too?

The other day my copy of Docker Desktop on two different work laptops prompted me to update. And neither would work properly after the update completed. In case this issue is affecting others, here's the saga of what I saw and two ways it can be fixed:

Strange Docker / Zookeeper errors

You can't win them all...

Usually with these blog posts, I find a problem, I fight with it for a bit, and then I solve the problem. But this post has been sitting half-written in my publishing queue since May (!) this year, and I have entirely failed to solve this issue. So I'm admitting defeat, and publishing this anyway because maybe one of you knows the answer. Or at least it might serve as a warning...

My issue is that I've been working through some really odd and annoying Solr issues which only manifest in Docker on one laptop. I'm really not sure if these are issues that others might see, or if this is a problem that's entirely down to this laptop's setup. But they're definitely a problem...

Docker without the desktop

If that license fee isn't for you...

If you're reading this soon after I post it then it's very nearly the end of the "grace period" where anyone can run Docker Desktop. As of 1st February if your business meets certain requirements you have to pay for each user. So what can us Sitecore devs do if we aren't in a position to pay that fee? Well the good news is you can run Docker without the Desktop bit, and it's not too tricky once you wrap your head around a few things...

A brief guide to Docker difficulties

It's not always easy to spot what's wrong

I spent some time working with a colleague who couldn't get his docker instance to start up happily this week. And it's reminded me that for all its positives, there are still some challenges with understanding the underlying issues when a developer container instance breaks. I realised I need a "go read this" post for the start of future discussions like this, so here are some problems you might see, and some diagnostic suggestions I wanted a convenient way to share:

Using ItemService in containers

I was asked to enable Sitecore's ItemService endpoints on a containerised instance of Sitecore recently, and my first pass through this didn't work. Turns out there's a key bit of documentation that seems to be missing for this scenario. Hence a quick post to help get info into Google. So if you need to do this, read on:

Deploying Dianoga in developer containers

I bumped into an interesting issue recently, which I though others might come across. Trying to run a project with Dianoga in it didn't work properly in a developer's Docker container – it kept failing whenever it was asked to process an SVG image. Why didn't that work? Here's why:

SolrCloud with Sitecore 10

A while back I wrote about some initial investigations I'd made towards having SolrCloud in a containerised Sitecore instance. Since I worked on that, Sitecore have shipped their "official" container approach, so I've revisited my experiments using the examples Sitecore provides.

What's interested me in Sitecore's use of Docker

Now that Sitecore 10 is out, I've been having a dig into the new Docker approach that's been released. There are some interesting differences here between Sitecore's official approach and the way the community scripts I'd experimented with worked – and I've learned a few interesting new things as a result of having a read of the examples provided. Here are the things that caught my attention:
