After coffee break, I accidentally bring lightning Talk about “IRGHS”, one of BlankOn product research. Only 5 minute, but still give me goosebumps. I talk partially in Bahasa Indonesia and english. After that, the committee get the session, bring door prize to lucky participant.

I join talk “The experience of the KLAS roadshow to ignite the spirit of Open Source in East Java, Indonesia” by Darian after lunch. Nice talk about how to encourage people to start engage FOSS Community. After that, I join Syamsul Maarif class, talk about “Current State of BlankOn Linux Development” as me as part of Pengembang BlankOn.

After class session, coffee break, I join to main hall. Watching LT session again. There is Khairul, from Ubuntu Malaysia. He purpose to bring GNOME.Asia Summit 2020 to Kuala Lumpur. Lets do that!

We held two big international conference and same month but in the difference weeks. openSUSE Asia Summit and GNOME Asia Summit. It is cool to see more people came, join and prepare to contribute for FOSS Community like GNOME Desktop or openSUSE. Some people came as speaker, talk for first time. Some come for their first conference in English. :D. I happy see new face, new people join community and hope it will last longer. See you again in online, telegram, facebook and mailing list.

Special thanks to openSUSE for sponsoring my travel.

Migrasi Metabase dari EBS ke Kubernetes

Setelah sukses mencoba Kubernetes di Binar Academy untuk semua service di aplikasi, kerjaan selanjutnya adalah memigrasikan service-service lain. Salah satunya adalah Metabase. Metabase di Binar Academy sebelumnya masih menggunakan AWS EBS (Elastic Beanstalk).

Bagaimana saya memigrasikan Metabase dari EBS ke K8S?

Berikut tahap yang saya lakukan.

  1. Hentikan layanan metabase di EBS.
  2. Catat credential database dari RBS (rds url, username, password, db_name)
  3. Buat YML K8s untuk Metabase.
    YML ini saya temukan di github zenyui | Thanks bro. Saya memodifikasi sesuai kebutuhan saya, K8s with kops on AWS.
  4. Lakukan deployment
    kubectl apply -f recipes/p-metabase.yml
  5. Atur domain ELB ke domain yang diinginkan pada dashboard (saya menggunakan cloudflare)
  6. Lakukan konfigurasi ulang Metabase.
  7. Hapus service Metabase dari AWS EBS.

Berikut YML Metabase:

Semoga membantu.

Implementasi Ingress, ELB dan SSL (Bagian 6)

Membaca dari tulisan ini untuk mengetahui perbedaan NodePort, LoadBalancer dan Ingress.

Apa itu Ingress?

Di Kubernetes, Ingress adalah objek yang memungkinkan akses ke layanan Kubernetes dari luar cluster Kubernetes. Konfigurasi ini diatur dengan membuat kumpulan peraturan (rules) yang menentukan koneksi masuk mana yang boleh menjangkau layanan apa.

Konfigurasi ini memungkinkan untuk menggabungkan aturan perutean menjadi satu pintu. Misalnya, untuk mengatur alamat ke layanan api-v1, dan mengatur alamat ke layanan api-v2. Dengan Ingress, kita dapat mengatur ini tanpa membuat banyak LoadBalancer atau mengekspos setiap layanan di Node. Karena kenaikan jumlah loadbalancer artinya menaikan biaya bulanan.

NGINX Ingress hanya merupakan salah satu implementasi Ingress Controller menggunakan NGINX. Selain NGINX, bisa juga menggunakan Traefik dan lainnya.

ELB (Elastic Load Balancing)

ELB di Kops AWS digunakan sebagai domain akhir yang digunakan user untuk mengakses service. Bentuknya berupa kombinasi acak angka dan huruf seperti berikut Lanjutkan membaca “Implementasi Ingress, ELB dan SSL (Bagian 6)”

Deploy Aplikasi NodeJS di Kubernetes KOPS AWS (Bagian 5)

Sudah install-install, dilanjut mendeploy aplikasi sederhana di K8s. Panduan ini saya sadur dari tautan github ini. Pilih bagian 6 Kops. Pada bagian ini saya berasumsi docker, kubectl, kops sudah terpasang. Cluster k8s sudah dibuat. Dashboard k8s sudah bisa diakses.

Step Ujicoba

Clone Repo

saya membuat garpu dari repo dan menyesuakan sedikit dengan kebutuhan saya.

git clone
cd nodejs-aws-workshop/cd 6\ -\ Kubernetes\ \(kops\)


Konsepnya adalah ada dua aplikasi nodejs (locations dan characters) yang jalan di port 8081. Kemudian akan dimapping oleh nginx sebagai load balancer. Konfigurasi minimalnya akan seperti ini:

location /api/locations {
  proxy_pass http://locations-service:8081;
location /api/characters {
  proxy_pass http://characters-service:8081;

Selanjutnya kita akan membangun image dari 2 service tadi (locations dan characters) plus nginx. Kemudian image yang sudah dibangun akan kita unggah ke docker registry (Docker Hub). Selanjutnya kita akan memasang dua aplikasi itu ke cluster k8s. Dilanjutkan dengan mengekpos dua aplikasi itu sehingga bisa diakses publik.

Merunut Tahun 2018

Sudah dipenghujung tahun 2018, sedikit mengulas balik. Kuucapkan syukur kepada Tuhan untuk semua perjalanan, ke pulau keberapa entah. Awal tahun 2018 merupakan fase lambat menurutku. Tak banyak yang aku lakukan. Masih banyak catatan yang lupa. Beberapa badai pikiran. Ku hampir limbung. Dan buku “Budak” itu masih akan menjadi mimpi yang akan ku tempuh. Ku mulai;

Agustus 2018

  • openSUSE Asia Summit 2018 digelar di Taiwan, ikut nimbrung sebagai pembicara.
  • Mengundurkan diri dari Peentar sebagai DevOps Engineer
  • Mengundurkan diri dari DevOps Master dan
  • Mencoba menjadi Talent Acquisition di Binar Career Hub

Terbang ke Ambon, bersama Binar Terangi Bangsa dan Telkomsel. Binar Academy Batch Ambon dimulai. Dan menyelakan diri menapak tilas Pulau Buru (yang catatannya masih dalam draft kepalaku). Lanjutkan membaca “Merunut Tahun 2018”
