I get the error when building my docker kibana container:

failed to solve with frontend dockerfile.v0: failed to create LLB definition: no match for platform in manifest sha256:XXX: not found

Solved this error by running:

  1. Go to your local docker desktop, clicked setting
  2. Click Docker Engine, set `buildkit` to false :
"features": {
"buildkit": false

but then hit another error:

no matching manifest for linux/arm64/v8 in the manifest list entries

solved by editing docker-compose for the container:

platform: linux/amd64



Problem: I get this error from running my custom lumen packagist (version — 8.3.1):

Class 'League\Flysystem\Adapter\Local' not found


This is an issue from installing version 2.0 for league/flysystem, you need to install league/flysystem packagists to version 1 in order to access the missing adapter by running:

composer require — dev league/flysystem ^1.0

mysql:platform: linux/amd64
