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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

$ ../rebar create-node nodeid = exemplar $ ls -lR total 8 drwxr-xr-x 5 iw iw 170 13 Jan 13:33 overlay -rw-r--r-- 1 iw iw 612 13 Jan 13:33 reltool.config ./overlay: total 0 drwxr-xr-x 3 iw iw 102 13 Jan 13:33 bin drwxr-xr-x 3 iw iw 102 13 Jan 13:33 erts-vsn drwxr-xr-x 4 iw iw 136 13 Jan 13:33 etc ./overlay/bin: total 8 -rw-r--r-- 1 iw iw 3368 13 Jan 13:33 exemplar ./overlay/erts-vsn: total 0 drwxr-xr-x 4 iw iw 136 13 Jan 13:33 bin ./overlay/erts-vsn/bin: total 16 -rw-r--r-- 1 iw iw 1118 13 Jan 13:33 erl -rw-r--r-- 1 iw iw 2940 13 Jan 13:33 nodetool ./overlay/etc: total 16 -rw-r--r-- 1 iw iw 334 13 Jan 13:33 app.config -rw-r--r-- 1 iw iw 423 13 Jan 13:33 vm.args

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:

1 2 3 4 5 6 7 8 9

$ ls -l rel/exemplar/ total 0 drwxr-xr-x 3 iw iw 102 13 Jan 13:52 bin drwxr-xr-x 8 iw iw 272 13 Jan 13:52 erts-5.7.4 drwxr-xr-x 3 iw iw 102 13 Jan 13:52 erts-vsn drwxr-xr-x 4 iw iw 136 13 Jan 13:52 etc drwxr-xr-x 33 iw iw 1122 13 Jan 13:52 lib drwxr-xr-x 3 iw iw 102 13 Jan 13:52 log drwxr-xr-x 4 iw iw 136 13 Jan 13:52 releases
