Biasanya, pipeline CI / CD dibangun di atas server fisik dan mesin virtual. Platform kontainer seperti Kubernetes dan OpenShift datang ke adegan ini jauh kemudian. Namun, karena semakin banyak beban kerja yang dimigrasi ke platform OpenShift, begitu pula pipeline CI / CD, dan tugas pipeline semakin banyak dijalankan di dalam container yang berjalan di cluster.
Postingan ini adalah terjemahan dari blog teman kita Ales Nosik, penulis blog bernama sendiri ("Membantu Anda menjelajahi dunia Kubernetes"). Motto Ales: "Pengembang dan arsitek perangkat lunak sangat menyukai teknologi baru, sumber terbuka, dan budaya DevOps. Menjadikan dunia tempat yang lebih baik dengan perangkat lunak."
Anda dapat mengajukan pertanyaan apa pun setelah membaca Ales di komentar. Nah, dan di mana tanpanya - Ales ingin menyajikan untuk pertanyaan paling rumit satu set backpacker dengan peta rute dari Red Hat. Dan topi.
Di dunia nyata, perusahaan tidak terbatas pada satu klaster OpenShift, tetapi memiliki beberapa klaster sekaligus. Mengapa? Untuk menjalankan beban kerja baik di berbagai cloud publik dan di fasilitas TI mereka sendiri. Atau - jika organisasi tetap setia pada satu penyedia platform - untuk beroperasi secara efektif di berbagai wilayah di dunia. Dan terkadang diperlukan beberapa cluster dalam satu region, misalnya jika terdapat beberapa zona keamanan yang masing-masing harus memiliki cluster sendiri-sendiri.
