Release Handling

Introducing reltool.config

Rebar produces the reltool.config configuration file in response to performing the create-node command. The reltool.config contains configuration information consumed by rebar, and Reltool (the release management tool introduced in the Erlang R13B distribution).

Create the application:

1	$ ./rebar create-app appid = exemplar

Notice: The commands 'create-app' and 'create-node' can be seen in rebar_templater.erl . Also, the variables that may be supplied to these commands can be seen in the respective templates, simpleapp.template and simplenode.template .

And to create the node:

Manually create the rel directory:

1 2	$ mkdir rel $ cd rel

create the node:


$
 ../rebar create-node nodeid
=
exemplar





$
 ls -lR

To produce a release:

Add the following to rebar.config:

{sub_dirs, ["rel"]}.

and perform:

1 2	$ ./rebar generate ==> rel (generate)

This will produce the target system exemplar within the rel directory:


$
 ls -l rel/exemplar/
