Plans

Ferry has no instance types. A plan becomes the memory and CPU limits of the containers.

A plan sets the resource limits of each container.

Examples

Entry	`plan`	Memory	CPU
Service	`starter`	512 MiB	0.5 CPU
Service	`standard`	2 GiB	1 CPU
Service	`pro`	4 GiB	2 CPUs
Service	`free`	The memory of the plan	0.5 CPU (0.1 on Render)
Postgres	`basic-1gb`	1 GiB	Not set by the plan
Key Value	`starter`	256 MiB	Not set by the plan

The blueprint reference lists each plan.

A resource with no plan and no limit keys gets the defaults of the server: 512 MiB and 1 CPU for each container.

The server can have other defaults: --default-memory-limit and --default-cpu-limit.

The keys memoryLimit and cpuLimit replace the limits of the plan. See the blueprint reference.

Databases

Each entry of databases becomes a Postgres datastore on the Ferry server.

You can change the file and apply it again. Ferry updates what changed and deletes nothing.
