ada yg kurang clear ga broski? @r17x

r17x commented 1 week ago

@faultables directory home isinya apa aja (selain dari crontab)?

faultables commented 1 week ago

bisa cek manual di ssh raspi ls ~ pak kwwkwkwk

r17x commented 1 week ago

@faultables disini ada banyak 

Desktop  Documents  Downloads  Music  Pictures  Public  README  Templates  Videos  cachex  duckdns  komunix.org  nfs  nice  npmx  snap
faultables commented 1 week ago

coba yang cachex/ dan npmx/ dulu pak sisanya harusnya ga begitu penting

r17x commented 1 week ago

@faultables yang serve 2 file itu pakai service apa? nginx atau caddy?

faultables commented 1 week ago

caddy bro

r17x commented 1 week ago

@faultables berarti gw coba mulai dengan membuat cachex dan npmx pakai caddy + crontab?

faultables commented 1 week ago

yesss. yang gw tahu si nix kan bisa bikin kyk "ga perlu musingin nyimpen script/binary dimana" nah better klo kita bisa pakai pendekatan itu juga, kita pakai. jadi flow (contoh, untuk cache.komunix.org) itu seperti ini:

1. caddy serve static file /home/komunix/cachex/index.html

dan berikut config nya nya:

[Unit]
Description=caddy
ConditionFileIsExecutable=/usr/local/bin/caddy
After=syslog.target network-online.target

[Service]
StartLimitInterval=5
StartLimitBurst=10
ExecStart=/usr/local/bin/caddy file-server --root /home/komunix/cachex --listen 127.0.0.1:2022
StandardOutput=null
StandardError=journal

Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target

file tersebut ga harus di /home/komunix, yang penting file nya ada (di step 2). take note bagian --root di ExecStart di atas

2. index.html tersebut di-generate oleh script gen.sh

script nya sederhana, untuk cache.komunix.org konten nya seperti ini (di /home/komunix/cache/gen.sh):

export timestamp=$(date +%s)
export usage=$(df -h /home/komunix/nfs/nix-cache | tail -n1)
export total_cache=$(find /home/komunix/nfs/nix-cache -type f | wc -l)
export nice=$(du -sh /home/komunix/nfs/nix-cache)

envsubst < /home/komunix/cachex/index.html.tpl > /home/komunix/cachex/index.html

disini yang penting adalah file template nya (yg technically cuma teks biasa), yang untuk cache.komunix.org, kontennya seperti berikut (di /home/komunix/cache/index.html.tpl):

<!DOCTYPE html>
<html lang="en">

3. script gen.sh tersebut dijalankan setiap menit melalui cron

untuk crontab nya seperti ini:

* * * * * /home/komunix/cachex/gen.sh

and that's it

kesimpulan

intinya adalah gimana caranya menghindari sebisa mungkin file-file yang di manage secara manual. seperti, yang sekarang, si caddy serve static server di /home/komunix/cache karena kita secara eksplisit ngasih tau letak file nya dimana, karena kita yang manage file tersebut. ga masalah klo misalnya nanti menjadi --root /nix/store/caddy-cachex-1-1-0/etdryftugyihojpk/ selama possible

entry di crontab pun kasusnya sama, setiap menit menajalankan /home/komunix/cachex/gen.sh karena kita secara eksplisit ngatur (nyimpen) file tersebut disana. ga masalah klo misalnya nanti menjadi * * * * * /nix/store/komunix-gen-1-1-0/dfghg5342qfds/cachex.sh selama possible

mental model gw untuk kasus ini kyk pakai home-manager yg ga perlu musingin manajemen dotfiles. i think misi nix untuk membuat konfigurasi komputer tanpa musingin manajemen file konfigurasinya, menjadi possible
