### How to prevent variable interpolation in `docker-compose.yml`
When [[using Docker Compose]] and you configure the `ADMIN_TOKEN` via the `environment` directive you need to escape all five occurrences of the dollar sign `$` in the generated argon2 PHC string using two dollar signs `$$` in order to prevent [variable interpolation](https://docs.docker.com/compose/compose-file/#interpolation), e.g.:
