M1 macでcolima+dockerで環境構築した時に変なとこではまったのでメモ。

colima, docker, docker-composeをinstall

brew install docker docker-compose colima

colima start

colima start --profile x64 --arch x86_64 --cpu 8 --memory 8 --disk 128 --mount '~/workspace/my/colima/docker-compose:w' --dns 8.8.8.8

Permission deniedがもの凄い出てた...

色々と調べてみたら、docker-composeのmysqlの箇所に
「user:1000:1000」を追加するという対応策を見つけたので、追加して実行。

~~
        volumes:
            - ./docker/mysql/data:/var/lib/mysql
            - ./docker/mysql/my.cnf:/etc/mysql/conf.d/my.cnf
            - ./docker/mysql/sql:/docker-entrypoint-initdb.d
        user: 1000:1000 # ← これを追加
        ports:
            - 3306:3306
            - 3307:3306
~~

無事にmysqlコンテナは起動してくれてコンテナ内にも入れた。

$ docker exec -it sample-mysql bash
I have no name!@XXXXXXXXXX:/$ mysql -u admin -h localhost -p -P 3306 sample

ちなみに、

        volumes:
            - ./docker/mysql/data:/var/lib/mysql:rw
            - ./docker/mysql/my.cnf:/etc/mysql/conf.d/my.cnf:rw
            - ./docker/mysql/sql:/docker-entrypoint-initdb.d:rw

これでは解決しなかった。。。
