Can't get template variable substitution to work with profile releases #2710
Comments

I have added the non working configuration to this repo, under the linked branch (non_working_profiles) https://github.com/fkrause98/rc_example/tree/non_working_profiles. You should be able to reproduce this error by just cloning, doing You might get this error output: But the error is still the same, an invalid node name and inside the error output: {{node}} instead of its substitution |

My guess is that overlays are getting overwritten in a later pass when My understanding is that the overlays and sys.config files are not expected to be part of the same set, but rather operate as unrelated elements. |

Sorry, I don't think I follow you quite right, can you go a bit more into detail? 😅 |

Okay I found the issue and it's a quick fix: #2711 |
|
Ok, I fixed It locally, for some reason the variable {relx, [{release, {rc_example, "0.1.0"}, [rc_example]},
{dev_mode, true},
{include_erts, false},
{sys_config, "conf/sys.config"},
{vm_args, "conf/vm.args"},
{extended_start_script, false},
{overlay, [{template, "conf/sys.config", "releases/{{default_release_version}}/sys.config"},
{template, "conf/vm.args", "releases/{{default_release_version}}/vm.args"}]}]}.
To this {relx, [{release, {rc_example, "0.1.0"}, [rc_example]},
{dev_mode, true},
{include_erts, false},
{sys_config, "conf/sys.config"},
{vm_args, "conf/vm.args"},
{extended_start_script, false},
{overlay, [{template, "conf/sys.config", "releases/{{release_version}}/sys.config"},
{template, "conf/vm.args", "releases/{{release_version}}/vm.args"}]}]}.Fixes my issue, at least |

rebar3 reportto your message:Current behaviour
Expected behaviour
I expected the release to be executed, and have as node name "[email protected]" as I have stated in my config, seems like the node name is not setting as it should be because of the
[#{clean_halt => true,name => '{{node}}'...line in the error output. If I hard code the values, the release works.This is what I have in my rebar.config:
{relx, [{release, {rc_example, "0.1.0"}, [rc_example]}, {dev_mode, true}, {include_erts, false}, {sys_config, "conf/sys.config"}, {vm_args, "conf/vm.args"}, {overlay, [{template, "conf/sys.config", "releases/{{default_release_version}}/sys.config"}, {template, "conf/vm.args", "releases/{{default_release_version}}/vm.args"}]}, {extended_start_script, false}]}. {profiles, [{dev1, [{relx, [{overlay_vars, "conf/vars_dev1.config"}]}]}, {dev2, [{relx, [{overlay_vars, "conf/vars_dev2.config"}]}]}, {dev3, [{relx, [{overlay_vars, "conf/vars_dev3.config"}]}]}]}.And inside each profile file:
This variables are supposed to be used by both the sys.config and vm.args files:
I've been reading rebar3's documentation and everything looks ok, I can't really figure out/debug why the node's name is not setting as it should be. If it helps, I'm following this (outdated) tutorial https://github.com/lambdaclass/riak_core_tutorial#3-setting-up-the-cluster which was originally written for OTP 19, 20 and 21 and rebar 3.6.1.
