Tentang Lembar Contekan Docker
Lembar contekan CLI Docker ini mengatur pekerjaan container berdasarkan objek: image, container, opsi run, exec dan log, build dan Dockerfile, volume, network, Docker Compose, perintah registry, dan pembersihan sistem. Setiap baris adalah perintah lengkap dengan deskripsi satu baris.
Perintah Docker panjang dan sarat flag — pemetaan port, volume mount, variabel lingkungan — dan perbedaan antara container yang berfungsi dengan kegagalan yang membingungkan sering kali hanya terletak pada satu flag. Bagian opsi run dan Compose menjaga flag-flag tersebut tetap terlihat, bukan sekadar dihafal.
Lembar contekan ini gratis dan berbasis client-side. Saring perintah secara langsung dengan kotak pencarian, lompat antar bagian dari daftar isi yang sticky, salin perintah apa pun dengan satu klik, dan cetak halaman ini — bagian pembersihan saja sudah akan menghemat ruang disk Anda.
Cara menggunakan Lembar Contekan Docker
- Telusuri bagian-bagiannya, dari Image dan Container hingga Volume dan Network sampai Sistem & pembersihan.
- Cari sebuah tugas seperti port, mount, atau prune untuk menyaring perintah secara langsung.
- Lompat ke Opsi run atau Docker Compose melalui sidebar sticky untuk perintah yang sarat flag.
- Klik sebuah perintah atau ikon salinnya untuk menyalinnya, lalu sesuaikan nama image, port, dan path.
- Cetak lembar contekan ini untuk referensi docker di samping terminal Anda.
Pertanyaan yang sering diajukan
Sepuluh bagian: image, container, opsi run, exec dan log, build dan Dockerfile, volume, network, Docker Compose, perintah registry, dan pembersihan sistem.
Ya. Bagian Compose khusus membahas cara menjalankan dan menghentikan stack, membangun ulang, melihat log, dan perintah multi-container lainnya yang dipakai dalam pengembangan sehari-hari.
Lompat ke bagian sistem dan pembersihan — bagian ini mencantumkan perintah prune untuk menghapus container, image, volume, dan network yang tidak terpakai, beserta catatan tentang apa yang dihapus masing-masing.
Ya. Bagian build dan Dockerfile memasangkan instruksi umum dan perintah build dengan deskripsi singkat, berdampingan dengan opsi run yang akan Anda pakai untuk menjalankan image yang sudah dibangun.
Ya, sepenuhnya gratis — bisa dicari, bisa dicetak, dan dirender di browser Anda tanpa akun.
