[英]Erlang / Rebar3 - How to add an application to release but not launch it?
I have an umbrella project, includes main_app, app1, app2.我有一个伞形项目,包括 main_app、app1、app2。 main_app can work singe, or can work with and manage app1 and app2. main_app 可以单独工作,也可以使用和管理 app1 和 app2。
The decision about the launching of app1 and app2 is on external side (special config file, filled by a user). app1 和 app2 的启动决定在外部(特殊配置文件,由用户填写)。
I use rebar.config, part of it:我使用 rebar.config,其中的一部分:
{lib_dirs, ["apps"]}.
{sub_dirs, [
"apps/main_app",
"apps/app1",
"apps/app2"
]}.
{relx, [{release, {main_app, "0.8.6"},
[kernel,
sasl,
main_app]},
{sys_config, "./config/sys.config"},
{vm_args, "./config/vm.args"},
{dev_mode, true},
{include_src, true},
{include_erts, false},
{extended_start_script, true}]
}.
{profiles, [
{prod, [
{relx, [
{dev_mode, false},
{include_erts, false},
{include_src, false},
{sys_config, "./config/prod_sys.config"},
{vm_args, "./config/prod_vm.args"}
]}
]}
]}.
If I use sudo rebar3 shell
- I can manage app1 and app2.如果我使用sudo rebar3 shell
- 我可以管理 app1 和 app2。 But if I pack a release by sudo rebar3 as prod tar
- I get a tar archive which does not include beam files of app1 and app2.但是,如果我将sudo rebar3 as prod tar
的发布sudo rebar3 as prod tar
- 我会得到一个不包含 app1 和 app2 的束文件的 tar 存档。 I know, if I put app1 and app2 to release section in the list with kernel, sasl, main_app
- my needed apps will be added to release, but they will be automatically launched (I need to launch by myself)!我知道,如果我将 app1 和 app2 放在带有kernel, sasl, main_app
的列表中的 release 部分 - 我需要的应用程序将被添加到 release 中,但它们会自动启动(我需要自己启动)!
How to configure rebar for adding all the libraries or applications to tar release, but not to launch them during starting main_app?如何配置 rebar 以将所有库或应用程序添加到 tar 版本,但在启动 main_app 期间不启动它们?
Thanks in advance!提前致谢!
Use the {app, load}
syntax:使用{app, load}
语法:
{relx, [
{release, { Project, Version }, [
{app1, load}
...
That way, the application is loaded but not started.这样,应用程序已加载但未启动。 If you want to neither load nor start the application, use {app, none}
(the code is still loaded, though).如果您既不想加载也不想启动应用程序,请使用{app, none}
(尽管代码仍会加载)。
