Baru sadar sekarang ternyata sudah ada 186 artikel/tutorial sejak tahun 2003 yang sudah saya tulis(author) dan publish di internet melalui blog saya di http://henry.gultom.or.id . Saya belajar  di komunitas jadi kita harus giving back ke komunitas kembali dan jangan simpan sendiri ilmunya nanti tidak menjadi berkat.

Era platform open-source masih terus digunakan sampai sekarang dan menjadi sangat populer, sejak 25 August 1991 Linus Benedict Torvalds mempublish Linux kernel pertama kali dan berkembang sampai Linux Distribution pertama di release. Tahun 1993 distribusi Linux Slackware lahir dan diikuti di tahun yang sama Linux Debian.  Oke cukup bicara histori, kita lanjut ke pendatang baru yang lagi sangat tenar sekarang yaitu Kubernetes.

Kubernetes merupakan platform open-source yang digunakan untuk melakukan manajemen workloads aplikasi yang dikontainerisasi, serta menyediakan konfigurasi dan otomatisasi secara deklaratif. Kubernetes berada di dalam ekosistem yang besar dan berkembang cepat. Service, support, dan perkakas Kubernetes tersedia secara meluas Kubernetes menyediakan manajemen environment yang berpusat pada kontainer. Kubernetes melakukan orkestrasi terhadap computing, networking, dan inftrastruktur penyimpanan. Fitur inilah yang kemudian membuat konsep Platform as a Service (PaaS) menjadi lebih sederhana dilengkapi dengan fleksibilitas yang dimiliki oleh Infrastructure as a Service (IaaS).

Mau cepat paham ayo di coba/test/produce/reproduce jangan baca teori saja. Orang kita kadang malas mencoba, tapi maunya banyakin sertifikat saja.

Ujicoba saya kali ini menggunakan :
– Ubuntu 16.04.7 LTS (GNU/Linux 4.4.0-198-generic x86_64)
– Kubernetes dan Docker
– VM CPU and Memory 2Cores 4GiB running di Alibaba Cloud (sorry ini bukan promosi).

Let’s start, logged to VM using ssh :

sh-3.2# ssh root@47.254.16.185
The authenticity of host ‘47.254.16.185 (47.254.16.185)’ can’t be established.
ECDSA key fingerprint is SHA256:RveCyz8yQAJeS4dMElxwK3cWSUnZGdHirKrLmzIMRtc.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added ‘47.254.16.185’ (ECDSA) to the list of known hosts.
