目的
當我們使用docker後需要使用一些特定環境中的鏡像,網路上已經有很多現成的鏡像提供我們使用與搜尋,
使用後我們可能會做很多的改變,且這個改變之後也還需要再備份使用
搜尋
KEYWORD即你想要搜尋的關鍵字
docker search [OPTIONS] KEYWORD
假設我要跑一個magento,我可以先看線上有什麼樣的鏡可以使用,也有星星等級提供你選擇
P-MP15:magentodf puwu$ docker search magento

| Name, shorthand | Default | Description |
|---|---|---|
| --automated | Only show automated builds(僅顯示自動構建) | |
| --filter , -f | Filter output based on conditions provided | |
| (搜尋條件) | ||
| --limit | 25 | Max number of search results(顯示數量上限) |
| --no-trunc | Don’t truncate output(當離開時是否刪除) | |
| --stars , -s | Only displays with at least x stars(僅顯示至少評價大於X顆星) |
以下範例為搜尋三顆星評價且結束時不刪除的magento 映像檔
docker search --filter=stars=3 --no-trunc magento
挑選好以後就可以透過之前教學方式跑一個容器起來,以下提供完整進階的magento啟動指令(bitnami/magento)
docker run -d --name magento -p 80:80 -p 443:443 \
-e MAGENTO_DATABASE_USER=bn_magento \
-e MAGENTO_DATABASE_PASSWORD=your_password \
-e MAGENTO_DATABASE_NAME=bitnami_magento \
--net magento-tier \
--volume magento_data:/bitnami \
bitnami/magento:latest
備份
當我們操作完一陣子後把所有預設環境都處理完成後,想做一個備份檔案時怎麼處理呢？
其實也很簡單,可以使用 docker export 命令
P-MP15:magento_bk puwu$ docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4aa7e364306e alexcheng/magento:1.8.1.0 "/sbin/my_init" 24 hours ago Up 24 hours 0.0.0.0:80->80/tcp magentodf_web_1
P-MP15:magento_bk puwu$ docker export 4aa7e364306e > magentobk200304.tar
P-MP15:magento_bk puwu$ ls -la
total 1705792
drwxr-xr-x 3 puwu staff 96 Mar 4 18:44 .

-rw-r--r-- 1 puwu staff 866451456 Mar 4 18:44 magentobk200304.tar
之後我們可以將快照透過docker import導入為鏡像puwutest/magento:v1
P-MP15:magento_bk puwu$ docker export 4aa7e364306e > magentobk200304.tar
P-MP15:magento_bk puwu$ ls
magentobk200304.tar
P-MP15:magento_bk puwu$ cat magentobk200304.tar | docker import - puwutest/magento:v1
sha256:c28dd8792d9f1f763eb780ef8e37d891fb2204fcaa4e5ae190af32cb71375837

如此就可以做一個簡單循環的簡單環境佈建操作了
