當 Rails 遇上 Docker,環境部署原來是這樣!? - 詹昇
由於場地問題,第二天我們移動到另一棟大樓啦!議程教室變動請見網站上的議程表。
歡迎來到 https://hackmd.io/@coscup/2019 共筆
- The image file may be corrupted
- The server hosting the image is unavailable
- The image path is incorrect
- The image format is not supported

Docker 特性
在 Docker 跑的 process PID 會從一開始算,但是在 Host 也會有一樣的 process,只是 PID 不同。在 Host kill 掉,在 Docker 裡面也會跟著消失
Docker 會使用到的東西
有 Dockerfile 做出 Image 然後就能產生一堆 container
還有一個檔案叫做 docker-compose 會告訴每一個 container 該怎麼開機
預想操作方式
在 Local 端做好 Docker Image 上傳到線上儲存庫(Ex: Docker Hub)再下載,,接著用 Docker-compose.yml 開機
範例製作方式
- The image file may be corrupted
- The server hosting the image is unavailable
- The image path is incorrect
- The image format is not supported
Learn More →- The image file may be corrupted
- The server hosting the image is unavailable
- The image path is incorrect
- The image format is not supported
Learn More →這邊用 Volumes 避免 container 週期結束時能把資料留在 Host OS
完整範例檔案
- The image file may be corrupted
- The server hosting the image is unavailable
- The image path is incorrect
- The image format is not supported

加上 nginx
需要客製化的 image
