The systemd service loads it as environment variables.
.SH EXIT STATUS
\fBminiflux\fR exits with status 0 on success and 1 on error.
With \fB\-healthcheck\fR, a non-zero status means the health check failed.
.SH EXAMPLES
Run the database migrations and create an admin user
from environment variables:
.PP
.EX
export DATABASE_URL="postgres://miniflux:secret@localhost/miniflux?sslmode=disable"
RUN_MIGRATIONS=1 CREATE_ADMIN=1 ADMIN_USERNAME=admin \e
ADMIN_PASSWORD=changeme miniflux
.EE
.PP
Start Miniflux with a configuration file:
.PP
.EX
miniflux \-c /etc/miniflux.conf
