OTP migrations fail to connect to Postgres with SSL

Environment

  • Installation type (OTP or From Source): OTP
  • Pleroma version (could be found in the "Version" tab of settings in Pleroma-FE): 2.0.50-2385-g47698fc3-develop
  • Elixir version (elixir -v for from source installations, N/A for OTP): N/A
  • Operating system: Alpine (in Docker), macOS
  • PostgreSQL version (psql -V): 11

Bug description

Running Pleroma migrations fails with the following when connecting via SSL:

** (EXIT from #PID<0.164.0>) an exception was raised:
    ** (RuntimeError) SSL connection can not be established because `:ssl` application is not started,
you can add it to `extra_application` in your `mix.exs`:

  def application do
    [extra_applications: [:ssl]]
  end

There's a related issue and PR against Postgrex.

To replicate:

  1. Run Postgres with SSL
  2. Build a new release via MIX_ENV=prod mix release
  3. Set ssl: true in prod.secret.exs
  4. Run ./bin/pleroma_ctl migrate. This should fail with the error above.

It looks like a reasonable patch for this is adding:

Application.ensure_all_started(:ssl)

to lib/mix/tasks/pleroma/ecto/migrate.ex.

The above snippet has fixed it in my case, so I'll raise a PR shortly. Raised: !2894 (merged)

I'm still a little confused why having :ssl in mix.exs in extra_applications doesn't fix this to begin with..
