私は docker と podman が初めてです。podman で MongoDB を実行したい。したがって、次のように実行してみてください:-
❯ podman run -it --name mongo -p 27017:27017 --mount type=volume,src=mongodbdata,dst=/data/db mongo
しかし、私はエラーが発生します
error: exec: "/usr/local/bin/docker-entrypoint.sh": stat /usr/local/bin/docker-entrypoint.sh: permission denied
これは何を意味するのでしょうか？ホストに「/usr/local/bin/docker-entrypoint.sh」というファイルすらありません。上記の同じコマンドを alpine Linux イメージでテストしたところ、動作しました
このマシンへのルート アクセス権がないため、システム管理者によって既にインストールされている podman を使用している理由
編集：
docker と podman の両方で root アクセスできるラップトップでテストしました。上記のコマンドで podman を docker に置き換えると機能します。Dockerイメージはpodmanと互換性があると思いました
ここに詳細があります：-
