接手開發一路辛酸心得

故事是這樣的......

Development Team

PM

工程師A(VTN)

我

工程師B(VEN)

有一天......

工程師B要請長（ㄔㄢˇ）假

你要負責VEN專案

接手VEN專案

專案結構

C + PHP + Go

VEN傳輸→C

VEN API service→Go

ven-web Dockerfile?

VEN網頁→PHP

Compile C & Run

Then....

Segmentation fault

(core dumped)

Why?

configuration setting issue......

But she doesn't tell me......

Environment is not consistency...

ven-web Dockerfile?

COPY VEN-Comm-pull /root

Fix some C codes...

OpenADR standard implementation issue

C codes are not easy to fix...

Writing Dockerfile

Building Docker image

Make environment consistency

Compiling, Building and environment setup

VEN傳輸→openadr-ven

VEN API service→ven-rest

Architecture

Deploy 30 VENs on same machine

How?

Docker-based architecture

Run 30 times docker run commands?

Run 30 times configure

Nginx subdomain?

Run 30 times configure

subdomain DNS Record?

No, I'm lazy guy.

Using Bash script to save my life.

Deployment Steps

  1. Export related Docker images

  2. Import related Docker images

  3. Setup credential settings file

    • Creating VEN REST token lists

    • Creating Cloudflare API token setting file

  4. Configure Nginx subdomain

  5. Configure subdomain DNS record via Cloudflare API

Why not using

container orchestration?

K8s, K3s, MicroK8s.......
