Macでlaravel,vue.js,docker（ローカルではdockerにnginxを使用）を使用してローカルでWEBアプリを制作しています。.envの設定がおかしいからだとは思いますが、dbとして使用しているローカルのmysqlに繋がらず、そのために
`php artisan migrate`
がエラーとなって詰まってしまっています。どこの設定が間違っているためにmysqlに繋がらないのかを知りたいのですがよろしくお願いします。

### 追記  
マルチポストしていることを説明し忘れました。内容は全く同じですが追記しておきたいと思います。

### 追記

コメントで助言されたのを試したところプロセスがうまく実行できていないことまでわかりました。

```

    % docker-compose ps
    NAME                COMMAND                  SERVICE             STATUS              PORTS

```

### 追記２

% docker-compose logs db の結果、'utf8mb4_0900_ai_ci'がおかしいとのことです。

```

    % docker-compose logs db

またthinkerで環境変数を確認したところ一部反映されてないようでここにも原因がありそうです。

のように 'utf8mb4_0900_ai_ci' でエラーとなるので

[(Resolved) Unknown collation:
utf8mb4_0900_ai_ci](https://tecadmin.net/resolved-unknown-collation-
utf8mb4_0900_ai_ci/)

のサイトを参考にdocker内を  
COLLATION を'utf8_general_ci'  
CHARACTER を'utf8'  
に変更したところ

（docker/mysql/my.cnfの部分にこの記述、 'utf8mb4_0900_ai_ci' があるのでコードを載せておきたいと思います↓）

    slow_query_log_file = mysql-slow.log
    long_query_time = 1.0
    log_queries_not_using_indexes = 0
    
    # General Log
    general_log = 1
    general_log_file = mysql-general.log
    
    [mysql]
    default-character-set = utf8mb4
    
    [client]
    default-character-set = utf8mb4
    
```

改めて `docker-compose logs db` を実行した結果、以下のようにエラーメッセージが変わりました。

```

    masa@MasaakinoMacBook-Air portfolio %

```

'utf8_general_ci' は CHARACTER 'utf8mb4' に対して有効でないため  
laravel内、およびdocker内の全てを  
COLLATION を'utf8_general_ci'  
CHARACTER を'utf8'  
に統一すると `php artisan migrate` が通りました。解決できました。ありがとうございました！‍♂️
