trying to get my first Phoenix app connected to Compose's Cloud Hosted Postgres DB and am unable to connect. I have verified that it is up and running. I get the following error:
[error] GenServer #PID<0.178.0> terminating
** (DBConnection.ConnectionError) tcp connect (postgres://*****@aws-us-east-1-portal.5.dblayer.com:16786/compose:5432): non-existing domain - :nx

These are my dependencies:
defp deps do
[{:phoenix, "~> 1.2.1"},
{:phoenix_pubsub, "~> 1.0"},
{:phoenix_ecto, "~> 3.0"},
{:postgrex, ">= 0.0.0"},
{:phoenix_html, "~> 2.6"},
{:phoenix_live_reload, "~> 1.0", only: :dev},
{:gettext, "~> 0.11"},
{:cowboy, "~> 1.0"}]
end
And my DB Config:
# Configure your database
config :hello_phoenix, HelloPhoenix.Repo,
adapter: Ecto.Adapters.Postgres,
username: "admin",
password: "******",
database: "compose",
hostname: "postgres://admin:******@aws-us-east-1-portal.5.dblayer.com:16786/compose",
pool_size: 10
And using this version of PostgresSQL : PostgreSQL 9.4.10
Any help would be greatly appreciated. :-) Y'all take care! -Chris
The hostname
of your database is aws-us-east-1-portal.5.dblayer.com
, not the whole postgres://...
. Also, you need to specify the port since it's not the default PostgreSQL port. This should work:
config :hello_phoenix, HelloPhoenix.Repo,
adapter: Ecto.Adapters.Postgres,
username: "admin",
password: "******",
database: "compose",
hostname: "aws-us-east-1-portal.5.dblayer.com",
port: 16786,
pool_size: 10
Since it seems you have a full database URL, probably the easiest solution for you will be to use that URL and let ecto decode it into the constituent parts that it needs for connecting.
config :hello_phoenix, HelloPhoenix.Repo,
adapter: Ecto.Adapters.Postgres,
url: "postgres://admin:******@aws-us-east-1-portal.5.dblayer.com:16786/compose",
pool_size: 10
Here's the documentation for that feature: https://hexdocs.pm/ecto/Ecto.Repo.html#module-urls
