Run elixir commands with gitlab-ci

Question

To automate elixir based application ,created a systemd service

[Service]
Type=simple
User=gitlab-runner
Group=gitlab-runner
Environment=LANG=en_US.UTF-8
 
WorkingDirectory=/path/to/elixirModule

ExecStart=/path/to/elixirModule/bin/elixir_module start
ExecStop=/path/to/elixirModule/bin/elixir_module stop

In .gitlab-ci.yml

build-project:
  stage: build_elixir_module
  tags: 
    - elixer-shell
  script:
    - mix ecto.drop
    - MIX_ENV=prod mix release
    - ls -lh _build/prod
    - cp _build/prod/elixir_module-0.1.0.tar.gz /path/to/elixirModule/
    - tar -xvf /path/to/elixirModule/elixir_module-0.1.0.tar.gz
    - sudo systemctl stop elixirModule
    - cd /path/to/elixirModule
    - bin/elixir_module start_iex 
    - EctoMnesia.Storage.storage_up(ElixirModuleRepo.config) 
    - ElixirModuleRepo.ReleaseTasks.migrate
    - sudo systemctl stop elixirModule

These two commands should be executed within iex terminal.

EctoMnesia.Storage.storage_up(ElixirModuleRepo.config) 
ElixirModuleRepo.ReleaseTasks.migrate

With current configuration, I get following error

iex(elixir_module@node1)1> $ EctoMnesia.Storage.storage_up(ElixirModuleRepo.config) 1468 bash: eval: line 125: syntax error near unexpected token `ElixirModuleRepo.config'

How to run these two commands inside iex. Also if my approach is buggy or any sort of wrong config, please let me know.
