Global fallback strategy

Global fallback strategy can be set by providing the Sidecar service with the ENTITLEMENTS_FALLBACK environment variable. It expects a value in a JSON object in a string format.

For example, the following global fallback configuration JSON structure:

{
  'feature-01-templates': {
    hasAccess: true,
    usageLimit: 1000,
  },
  'feature-02-campaigns': {
    hasAccess: true,
    isUnlimited: true
  }
}

Can be formatted using JSON.stringify and then set as value of ENTITLEMENTS_FALLBACK when running the container, replacing <tag> with the latest version in the ECR Public Gallery:

docker run -it -p 80:80 \ 
  -e SERVER_API_KEY="<SERVER_API_KEY>" \
  -e ENTITLEMENTS_FALLBACK='{"feature-01-templates":{"hasAccess":true,"usageLimit":1000},"feature-02-campaigns":{"hasAccess":true,"isUnlimited":true}}' \
  public.ecr.aws/stigg/sidecar:<tag>
