All, In the Sandbox section of the Apache Apex Development Environment Setup documentation ( https://apex.apache.org/docs/apex/apex_development_setup/#sandbox), instructions are provided for a vendor-specific Sandbox.
I would like to propose that these instructions be changed to reference the Apache Apex Sandbox instead, which is an Apache Bigtop build and available via docker at https://hub.docker.com/r/apacheapex/sandbox. Regards, Dean
