Release with docker problem

Questions / Help

I packaged the image using GitHub and exited directly when starting it. There was no daemon, so I searched for many problems but couldn’t solve them. Docker reported an error specifically:

/Opt/eadm/bin/eam: line 272:/opt/eam/arts 14.2.2/bin/erlexec: not found

I went inside Docker to check if the file did exist

Docker run -- rm - it -- name eadm redgreat/eam ls - l/opt/eam/erts 14.2.2/bin/erlexec
-Rwxr-xr-x 1 root 169680 Apr 19 13:27/opt/eam/arts 14.2.2/bin/erlexec

But when it’s being executed, it can’t be found

Docker run -- rm - it -- name eadm redgreat/eam/opt/eam/arts 14.2.2/bin/erlexec help
Exec/opt/eam/arts 14.2.2/bin/erlexec: no such file or directory

Can the big shots help me find the problem?
Github build statement

-Name: compile

Rebar3 clean
Rebar3 as prod release
Tar - czvf eadm - ${{steps. rep. outputs. label_version}}. tar. gz _build/prod/rel/eam

Dockerfile

WORKDIR/opt/eam

VOLUME/opt/eam

Rebar3. config

%%Release profiles
%%To create a release just run
%%Rebar3 as prod release
Relx, [{release, {eadm, "0.1.0"},
[eadm, nova, sasl]},

{sys_config, "config/sys. config"},
{vm.args, "config/vm. args"},
{overlay, [{copy, "config/prod_db. config", "releases/0.1.0/prod_db. config"]}

{vm-args src, "config/vm. args. src"}
]}
]}

{shell[
{config, "config/dev_sys. config. src"},

Ensure that all configuration files can be successfully mapped
The problem may occur in rebar3. config
{mode, prod},
{extended_start_script, true},
This place, but I don’t know how to solve it. I hope everyone can help me take a look

I haven’t marked some license issues yet. Thank you to the Nova framework writer

So if I understand it right.

You have a nova project and want to release a prod and have an docker image?

But when you start it crash?

If you want to check other repo using GitHub and docker you can look at this. GitHub - widgrensit/chatli

I will try to find some time to look at this.

Thank you for using Nova and we are happy to get feedback also.
