Quick Drop Deluxe Snag Config Files to Parameterize and Include in Your Packer Templates-2

I was recently setting up Minecraft Dedicated Server Java Edition. Most of my work with Minecraft has been with Bedrock edition which has a similar setup. Both have a server.properties file but the Java Edition has some different settings that I needed to configure.

It’s not a super great experience trying to copy and paste from vi while in an active SSH connection. Therefore, sometimes its handy to drop a file into the Azure Storage account for easier access.

Azure provides a pretty handy feature that allows you to execute a script on the server. This can be done via the Azure Portal so it’s more of a sneakernet type operation.

fi  
  
az storage blob upload \  
  --account-name stmc54251059 \  
  --container-name drop \  
  --name server.properties \  
  --file /home/mcserver/minecraft_java/server.properties \  
  --auth-mode login \  
  --overwrite

I setup a managed identity on the Virtual Machine which allows the machine to impersonate the identity but you still need to perform an az login in order to initialize the Azure CLI to…
