SonarQube Docker Container will not start
The Problem
We run our SonarQube instance in a Docker container hosted in an Azure Web App Service. Today, with no notice, it failed. We did the obvious, just tried to restart it and the startup process failed.
Looking at the Azure Web App's Log Stream we could see the following error repeated on each restart attempt

The Solution
Something in the back of my mind, from when we ran an on-premises SonarQube instance, made me think of a corrupt ElasticSearch index.
Using Azure Cloud Storage Explorer, I connected to the sonarqube-data file share and deleted the ES8 data folder
I then restarted the container and it started OK, recreating the ES8 folder and re-indexing the SonarQube content.
Thus far all appears to be OK.
