The Dagger SDK for Elixir.

Prerequisite

The SDK depends on docker and dagger commands, please make sure those commands are presents on your PATH.

Getting Started

Let's try this script below

Mix.install([:dagger])

# 1
Application.ensure_all_started(:inets)

# 2
{:ok, client} = Dagger.connect()

# 3
{:ok, output} =
  client
  |> Dagger.Client.container()
  |> Dagger.Container.from("hexpm/elixir:1.14.4-erlang-25.3-debian-buster-20230227-slim")
  |> Dagger.Container.with_exec(["elixir", "--version"])
  |> Dagger.Container.stdout()

IO.puts(output)

# 4
Dagger.close(client)

Here's what script do:

1. Start :inets application in order to use :httpc as a HTTP client.
2. Connecting to the Dagger Engine with Dagger.connect/1.
3. Create a new container from hexpm/elixir:1.14.4-erlang-25.3-debian-buster-20230227-slim and calling a command elixir with flag --version, get the standard output from latest command and printing it to standard output.
4. Close the connection.
