Discussion on: Deploy a Phoenix app with Docker stack

Hello, i can't make it run. I've got the following error when trying to run eval locally:

** (UndefinedFunctionError) function Ecto.Migrator.with_repo/2 is undefined or private

My endpoint.ex and release.ex are updated with you fragments and application name is changed to mine. Postgres is running on port 5432. Have you got any idea why is that ?

Ecto.Migrator.with_repo/2 was introduced in ecto_sql v3.1.2, maybe you have an older version.

Take a look at your mix.lock.

I am using those dependencies:

defp deps do
[
{:phoenix, "~> 1.3.4"},
{:phoenix_pubsub, "~> 1.0"},
{:phoenix_ecto, "~> 3.2"},
{:postgrex, ">= 0.0.0"},
{:phoenix_html, "~> 2.10"},
{:phoenix_live_reload, "~> 1.0", only: :dev},
{:gettext, "~> 0.11"},
{:plug_cowboy, "~> 1.0"},
{:comeonin, "~> 4.0"},
{:bcrypt_elixir, "~> 1.0"},
{:guardian, "~> 1.0"},
{:number, "~> 1.0.1"}
]
end

And the error is occurring too.
Any idea?

grep ecto_sql mix.lock

ecto_sql version has to be at least 3.1.2, eg:

"ecto_sql": {:hex, :ecto_sql, "3.1.5", ...
                               ^^^^^

Yes that was a problem. Thank you
