ARM64 Kubernetes Nginx Traefik Ingress Load Balance

Posted by on 2019/11/01 No comments

My original target purpose is very simple, build deploy several webserver and assigned a external ip for internet to access it.

Most kubernetes newbie install guide won’t mention how to do that. actually that’s very simple, for external ip, it needs a load balance controller like metallb for create a external ip address to access web server. and an Ingress contoller like Traefik for http/https route to right pods .

Raspberry 4 Pi + Kubuntu

Posted by on 2019/11/01 No comments

買了二塊 Raspberry 4 Pi 回來，本來是準備裝 K8s 的，但是在這之前要先跑個 ubuntu image 才對.

我買 Raspberry 4 Pi 的時候知道他要用 5V3A 的電源，但是我沒有想到我自己沒有 5V3A 的 USB 變壓器，手機用的含 Apple 87W USB-C 變壓器都不足瓦
Apple 87W 只能輸出 5V 2.4A
最後找了一個 Sony 可以輸出 5V 2.7A 才可以用，所以如果要買 Raspberry Pi 4 的人請注意一下

另外這一塊的外接是 Micro-HDMI，我也忘了買，記得還要加買 SD Card

ARM64 Ububtu GRUB Install

Posted by on 2017/02/02 No comments

碰到一台 ARM64 機器沒有裝 GRUB . ARM64 是跑 UEFI

首先先安裝 grub 

$ sudo apt install grub-efi-arm64 grub-efi-arm64-bin grub2-common

檢查 uefi partition 有沒有 mount 在 /boot/efi 下, 如果沒有可以 mount 上去, ex:

$ sudo mount /dev/sda1 /boot/efi

執行 grub-install 後就可以了

$ sudo grub-install /dev/sda
