### `REDMINE_SECRET_KEY_BASE`
This variable is used to create an initial `config/secrets.yml` and set the `secret_key_base` value, which is "used by Rails to encode cookies storing session data thus preventing their tampering. Generating a new secret token invalidates all existing sessions after restart" ([session store](https://www.redmine.org/projects/redmine/wiki/RedmineInstall#Step-5-Session-store-secret-generation)). If you do not set this variable or provide a `secrets.yml` one will be generated using `rake generate_secret_token`.
This variable is required when using Docker Swarm replicas to maintain session connections when being loadbalanced between containers. It will create an initial `config/secrets.yml` and set the `secret_key_base` value, which is "used by Rails to encode cookies storing session data thus preventing their tampering. Generating a new secret token invalidates all existing sessions after restart" ([session store](https://www.redmine.org/projects/redmine/wiki/RedmineInstall#Step-5-Session-store-secret-generation)).
