Environment / auth

FORMIO_PROJECT_URL
Optional, and the WEAKEST of the three project sources: a committed formio.json found by walking up from the working directory wins, then the per-directory mapping project_set writes, then this. It pins nothing — project_set can redirect a directory whose environment names a different project. Useful for a launch with nowhere to record a project, such as CI or a container (e.g. https://examples.form.io on the hosted cloud; self-hosted it is either https://your-project.your-domain.com or https://your-host/project-name, depending on how that deployment routes projects). Leave it unset and the agent asks for a project and records it per directory.
FORMIO_BASE_URL
Optional, and usually unnecessary: the base URL is DERIVED from the project URL — https://api.form.io for a project on a form.io host, the parent path for a project addressed as a sub-directory — and is asked for only when it cannot be derived, which is a path-less project URL on a customer domain. There is no default. Like FORMIO_PROJECT_URL it is the weakest source, behind a committed formio.json and the per-directory mapping.
FORMIO_API_KEY
secret
Form.io project API key. Optional — when omitted the server uses a browser-based portal login flow to obtain a JWT.
FORMIO_LOGIN_FORM
URL of a custom login form used by the browser-based portal login flow. Defaults to the deployment's portal login form.
FORMIO_FORCE_BROWSER
Set to 1 to attempt the browser login even where the server detects it cannot present one (CI, a container, a remote shell with no display). Use it when the login page is reachable from a browser elsewhere.
FORMIO_INSECURE_TLS
Set to 1 to skip TLS certificate verification. For local development against self-signed certificates only — never enable in production.
