# Environment changes
The following environment variables have been added:
CHEVERETO_ENABLE_TENANTS
This variable controls multitenancy support in Chevereto. When set to 1, it will be possible to create multiple independent sites within a single Chevereto infrastructure.
CHEVERETO_TENANT_ENFORCED
This variable allows defining a JSON object with environment variables that will be late enforced (overridden) on runtime for each tenant. This provides a way to set default configurations that apply to all tenants, while still allowing individual tenants to override specific settings as needed.
CHEVERETO_TENANT
When running Chevereto in multi-tenant mode, this variable specifies the target tenant for command-line interface (CLI) operations. It should be set to the unique tenant ID of the desired tenant.
CHEVERETO_TENANTS_API_REQUEST_SECRET
This variable is used to sign and verify requests to the Tenants API. When set to a non-empty string, all API requests must include a valid request signature header.
CHEVERETO_TENANTS_API_ALLOW_LIST
This variable allows restricting access to the Tenants API by specifying a comma-separated list of allowed IP addresses or networks. Only requests originating from these sources will be permitted to access the API.
CHEVERETO_TENANTS_API_KEY_SECRET
This variable is used to verify requests coming from a known Tenants API key.
CHEVERETO_PROVIDER_NAME
This variable is required in CHEVERETO_CONTEXT=saas setups to specify the service provider name for the Chevereto instance.
CHEVERETO_PROVIDER_URL
This variable is required in CHEVERETO_CONTEXT=saas setups to specify the service provider URL for the Chevereto instance.
CHEVERETO_JOBS_WORKER_INTERVAL
This variable is used to define how often (in seconds) the jobs worker will check for new jobs to process.
