Walkthrough

I posess a Spotify account so all I needed was to create a Spotify Developer account. A free spotify account will suffice.

First we need to setup the Spotify provider in order to obtain and use the resources. We will use the spotify provider here and pressing the use provider to display code or below.

terraform {
  required_providers {
    spotify = {
      source = "conradludgate/spotify"
      version = "0.2.7"
    }
  }
}

provider "spotify" {
  # Configuration options
}

provider.tf file should look like this and we will add the configuration options later:

Next we will need an API Key and this will be used to connect with the Spotify account. After creating a free Spotify account, Create a Developer account.

Enter the details to your liking except the Redirect URL must be:

http://localhost:27228/spotify_callback

Next we will need to grab the Client ID and Client Secret from the settings. We will store these two codes in an .env file.

SPOTIFY_CLIENT_ID=<enter_spotify_client_id_without>
SPOTIFY_CLIENT_SECRET=<enter_spotify_client_secret>

Should look like this below:

Run docker to retrieve the API Key. Confirm Docker Desktop is running first.

docker run --rm -it -p 27228:27228 --env-file .env ghcr.io/conradludgate/spotify-auth-proxy

Authorization successful will display if setup correctly. Copy the API Key and enter in a new file called terraform.tfvars. Then press the link in Auth Url: and the page will open to allow access to your Spotify account. Leave terminal open and create a new terminal:

Set a variable in the provider.tf file in configuration options:

Create the variables.tf file to hold the api_key variable as a string type:

variable "api_key" {
    type = string
}

The fun part is here. Now we will run terraform init which will run and install the files we have created.

Create Spotify playlist by first creating a playlist.tf file. The artist of choice is Larry June one of my favorite artists. More resources can be found on the documentation of the spotify provider here

data "spotify_search_track" "by_artist" {
  artist = "Larry June"
}


resource "spotify_playlist" "Larry_June_Terraform" {
  name        = "Larry June Terraform"
  description = "This playlist was created by Terraform"
  public      = true

  tracks = [
    data.spotify_search_track.by_artist.tracks[0].id,
    data.spotify_search_track.by_artist.tracks[1].id,
    data.spotify_search_track.by_artist.tracks[2].id,
  ]
}

After the information has been entered in, next is terraform plan in terminal. This will tell us the actions that will be executed when applied. I created a previous playlist so notice how that will be destroyed when the code has been updated:

terraform apply -auto-approve will apply the actions:

Docker issue: Docker for Windows: image operating system “linux” cannot be used on this platform.

• Check Docker Desktop Builders to ensure desktop-linux is up and running. if desktop-windows is running, the error will display. If error persists, try to uninstall and reinistall Docker.

Code Error: Inappropriate value for attribute "artist": string required.

• Confirm brackets aren't wrapped around the artist name. Only quotations.
