The following error is thrown:

ERROR: for php  Unknown runtime specified default

The error started occuring just after upgrading to the (currently) most recent beta: mac-v1.12.0-beta18-3-gec40b14

  • Diagnostic ID: 5015230F-7962-47D2-9B69-9AF0FA4B6C58

Seems related to https://github.com/docker/docker/issues/24343

Recreating all the containers solved the issue.
