將Golang應用部署到Docker

三、重新構建鏡像

重復先前的步驟，回到 gin-blog 的項目根目錄下執行 docker build -t blog .

四、創建並運行一個新容器

關聯

Q：我們需要將 Golang 容器和 Mysql 容器關聯起來，那么我們需要怎么做呢？

A：增加命令 --link dockermysql:mysql 讓 Golang 容器與 Mysql 容器互聯；通過 --link，可以在容器內直接使用其關聯的容器別名進行訪問，而不通過IP，但是--link只能解決單機容器間的關聯，在分布式多機的情況下，需要通過別的方式進行連接

運行

執行命令 docker run --link dockermysql:mysql -p 8080:8080 blog

$ docker run --link dockermysql:mysql -p 8080:8080 blog
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:	export GIN_MODE=release
 - using code:	gin.SetMode(gin.ReleaseMode)
...
Actual pid is 1

結果

檢查啟動輸出、接口測試、數據庫內數據，均正常；我們的 Golang 容器和 Mysql 容器成功關聯運行，大功告成 :)
