FlashDrive is a managed docker cluster, which means that we use very strict security rules for container isolation. Therefore, it is not possible to use instance<>port mapping or forwarding on FlashDrive.
Your instances from your account have direct access to all other instances that are managed under the same account and located inside the same datacenter (For example, Amsterdam 01) from scratch. You can access a database instance from several different web or worker instances.
It’s worth noting that DEV instances can only access other DEV instances inside the same datacenter.
You can also expose a port from your container directly through FlashDrive or by adding the command ‘ EXPOSE XX (XX = port to expose) ‘ in the Dockerfile used to build your instance.
