Getting Started Template - Docker issues

Question

Anyone getting problems following the Getting Started template? Tried 2 different installations and still getting errors.

https://doc.sitecore.com/xp/en/developers/101/developer-tools/walkthrough--using-the-getting-started-template.html

Some of the errors I am getting:

Error #1: level=warning msg="The \"R\" variable is not set. Defaulting to a blank string.

Error #2: docker-compose : failed to solve: failed to compute cache key: failed to calculate checksum of ref 3f3de231-5630-4e0d-9880-af4d75348d87::bxasqp1metajlwinwtmzknhdf: "/C:\\module\\db": not found

Answer 1

Double check that you did a "switch to Windows containers" from the Docker Desktop system tray. If you have the option to "Switch to Windows Containers" instead of "Switch to Linux containers" as a choice then this is probably the cause of at least Problem #2..

Answer 2

This looks very similar to what I faced after upgrading Docker Desktop and changing compose syntax to V2.

• Error#1 - You can search for an environment variable with "R" in it's value and remove escape characters.
• Error#2 - You can locate that volume in docker-compose file and add
  "\" at the end.

Make these 2 changes and try running up.ps1 again.

Answer 3

These errors occur when complex string values are present in .env files which are not wrapped in string literals.

For example:

SOME_VAR=BiMcQ.Rni:0w@\MstlSud>O+.StvvDm+vIvaBQb!3+-%@#;?Y5K|bJw@V9T[Lb63

The solution is to wrap all of your complex values like so:

SOME_VAR='BiMcQ.Rni:0w@\MstlSud>O+.StvvDm+vIvaBQb!3+-%@#;?Y5K|bJw@V9T[Lb63'
