Since lib.mdDoc is already defined as just id, this commit is a no-op as far as Nix (and the built manual) is concerned.

Environment variables to set.
|
|
|
|
Livebook is configured through the use of environment variables. The
|
|
available configuration options can be found in the [Livebook
|
|
documentation](https://hexdocs.pm/livebook/readme.html#environment-variables).
|
|
|
|
Note that all environment variables set through this configuration
|
|
parameter will be readable by anyone with access to the host
|
|
machine. Therefore, sensitive information like {env}`LIVEBOOK_PASSWORD`
|
|
or {env}`LIVEBOOK_COOKIE` should never be set using this configuration
|
|
option, but should instead use
|
|
[](#opt-services.livebook.environmentFile). See the documentation for
|
|
that option for more information.
|
|
|
|
Any environment variables specified in the
|
|
[](#opt-services.livebook.environmentFile) will supersede environment
|
|
variables specified in this option.

Secrets like {env}`LIVEBOOK_PASSWORD` (which is used to specify the
|
|
password needed to access the livebook site) or {env}`LIVEBOOK_COOKIE`
|
|
(which is used to specify the
|
|
[cookie](https://www.erlang.org/doc/reference_manual/distributed.html#security)
|
|
used to connect to the running Elixir system) may be passed to the

|
service without making them readable to everyone with access to

systemctl by using this configuration parameter.

Note that this file needs to be available on the host on which

`livebook` is running.
