envVarGroups

Each entry of envVarGroups creates one env group. A service links to it with fromGroup.

ferry.yaml

envVarGroups:
  - name: shared-settings
    envVars:
      - key: APP_ENV
        value: production

services:
  - type: web
    name: hello
    envVars:
      - fromGroup: shared-settings   # the link to the group

An env group is a set of variables that many services share. See Env groups.

The keys

Key	Type	Default	Notes
`name`	string	required	The name of the env group: 1 to 64 letters, digits, `-`, `_` or `.`.
`envVars`	list	none	The variables of the group. They have the same forms as the variables of a service, but not `fromGroup`. See envVars entries.

Which value wins

The own variables of a service win over the variables of its groups.
A group with a later link wins over a group with an earlier link.

See Which value wins.

A render.yaml after a Ferry upgrade

Older Ferry versions ignored plan. The first apply after the upgrade gives each entry with a plan its limits.

envVars entries

Each entry of envVars has one form only. The form tells where the value comes from.
