Idealnya berapapun kluster kubernetes yang berhasil dibuat, tetap akan mudah dikelola hanya dalam satu workspace. Workspace yang saya maksud adalah satu tab terminal di satu user di sistem operasi yang berjalan di laptop yang biasa saya gunakan untuk bekerja.
Sejak beberapa minggu kemaren hingga beberapa bulan kedepan, sepertinya jumlah kluster Kubernetes yang tim saya kelola akan naik secara berkala. Kenaikan jumlah kluster akibat kebutuhan bisnis, pemisahan beberapa produk, migrasi dan lain lain.
Kenaikan ini menyebabkan tim saya sebagai penjaga lilin dihadapkan bagaimana sih mengelola beberapa kluster kubernetes dengan mudah.
Keyword: Kubectl, Config, Context

Dalam praktik ini, saya memiliki dua buah kluster. k8s-siak-cluster dan k8s-kampar-cluster. Masing masih memiliki file kube config bawaan.
Ya modif ganti layar FHD ini akhirnya kesampaian. Saya membeli mod kit FHD dari nitrocaster ditambah tipe layar FHD rekomendasi dari nitrocaster.
Kemaren saya sempat membeli kit 2 buah, 1 dipake, 1 lagi buat cadangan. Tapi akhirnya 1 lagi saya lepas ke kawan di grup telegram. Kit ini saya beli pertengahan Juli 2019 silam seharga USD110. Satu bulan kemudian kit saya terima via pak pos.
Ini cuma ulasan pendek di sela-sela kegalauan turing nyepeda.
Masih mengingat beberapa pe-er komunitas, bareng Ish Sookun untuk mengerjakan beberapa tulisan terkait Kubic, dan turunannya. Belum sempat nyolek lagi. Saya mencoba menulis catatan kecil tentang mainan di akhir tahun. Ini sebenarnya merupakan catatan lama, namun tersisih di mesin berbeda.
Balik ke tema, saya sedang coba-coba menggunakan container daemon selain docker.
Podman
What is Podman? Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System. Containers can either be run as root or in rootless mode. Simply put: alias docker=podman.
Containers under the control of Podman can either be run by root or by a non-privileged user. Podman manages the entire container ecosystem which includes pods, containers, container images, and container volumes using the libpod library. Podman specializes in all of the commands and functions that help you to maintain and modify OCI container images, such as pulling and tagging. It allows you to create, run, and maintain those containers created from those images in a production environment.
Catatan: Tidak semua yang saya tulis ini adalah hal benar, dan dapat diimplementasikan mentah-mentah. Saya baru sampai diposisi, “Ini Jalan”, tapi belum tau bagian mana yang belum baik dan butuh ditunning.

Hae, sudah lama g nulis teknikal. Karena beberapa pekan, bulan terakhir ini masih terhipnotis pada tulisan piknik. Jadi balik ke judul. dan ke kubernetes.
Setelah sebelumnya menggunakan Kubernetes di AWS dengan jumawanya. Pake kops loh. Jumawa sejak awal saya makai kubernetes untuk production, agustus 2018. di saat kawan-kawan di jogja pada make k8s di GCP. Macam orang bingung kalo bertanya k8s di AWS dan kops saat itu.
Kemudian di pertengahan Agustus 2019, saya berpindah tempat ngetik. Tugas pertama. beres-beres mesin dan migrasi k8s. Saya bilang diawal, sanggup. Di hari pertama masuk ada mantra ajaib.
Kita pake Alicloud bang :D.
Someone
Saya nyengir cukup lebar. Bagaimana masang kubernetes di AliCloud? Pikiran pertama, menggunakan kops di alicloud. Setelah mencari catatan-catatan di github kops https://github.com/kubernetes/kops/issues/4127still on WIP but not know when will release.
Mencari patokan harga servise ACK, Kubernetes Service on Alicloud, sepertinya belum masuk. Sejujurnya saya belum terlalu paham cara menggunakan dashboard Alicloud. hanya ngasal klik klik. Berarti balik ke semi-semi kubernetes baremetal.
Mencari tulisan-tulisan lain, prove on concept tentang K8S HA mengantarkan saya ke beberapa tulisan:
Berikut adalah materi yang saya bawakan di IDDevOps Meetup 10 Oktober lalu di kantor Home Kredit Indonesia.
Materi yang saya bawakan ini lagi ujicoba. Saya melihat trend DevOps kini, lebih fokus kepada penggunaan tools, service dan hal teknis lainnya. Namun agak terlupa untuk juga mengelola DevOps dari sisi humanity, people, team.
Abstraksi
DevOps Culture merupakan sisi lain yang terjadi pada sisi System Engineer dari penerapan Agile/Scrum di pengembangan software. Sayangnya kultur ini terkadang lupa untuk diimplementasikan dengan baik. Tim hanya fokus penerapan Agile/Scrum pada tim developers. Padahal dengan adanya DevOps Culture, akan bisa makin mempercepat proses release produk secara masif, terstruktur dan sistematis. Di sesi ini saya akan menceritakan beberapa kasus yang pernah saya alami dalam implementasi DevOps Culture. Sehingga sedikit banyak dapat menjadi masukan untuk semua pihak.
Akhirnya perhelatan ini selesai. Berlokasi di Fakultas Teknik, Universitas Udayana Bali, 4-6 Oktober 2019. Saya berkesempatan berkontribusi sebagai panitia remote. Iya remote. Acara di Pulau Bali, tetapi panitianya di Blok M.

Menghitung jumlah konsumsi Sabtu dan Minggu, menu konsumsi Jumat siang dan makan malam, transfer-transfer.
