Linux CentOS7 64bit install docker Note

$sudo yum update

When Centos 6 ,5  befer then Centos7 version install

$sudo  yum install -y http://mirrors.yun-idc.com/epel/6/i386/epel-release-6-8.noarch.rpm

$sudo yum install -y docker-io

Centos7 is ready install

$sudo yum install -y docker

# set docker power on auto startup server

$ sudo systemctl enable docker.service

# start run docker

$ sudo systemctl start docker

# test docker run

$ sudo docker run --rm hello-world

Docker 包括三個基本概念

+

• 映像檔（Image）
• 容器（Container）
• 倉庫（Repository）

Docker命令查詢

基本語法

docker [OPTIONS] COMMAND [arg...]

一般來說，Docker 命令可以用來管理 daemon，或者透過 CLI 命令管理映像檔和容器。可以透過 man docker 來查看這些命令。

選項

-D=true|false
    使用 debug 模式。預設為 false。

-H, --host=[unix:///var/run/docker.sock]: tcp://[host:port]來綁定或者 unix://[/path/to/socket] 來使用。
    在 daemon 模式下綁定的 socket，透過一個或多個 tcp://host:port, unix:///path/to/socket, fd://* or fd://socketfd 來指定。

--api-enable-cors=true|false
    在遠端 API 中啟用 CORS 頭。預設為 false。

-b=""
    將容器掛載到一個已存在的橋接器上。指定為 'none' 時則禁用容器的網路。

--bip=""
    讓動態建立的 docker0 採用指定的 CIDR 位址; 與 -b 選項互斥。

-d=true|false
    使用 daemon 模式。預設為 false。

--dns=""
    讓 Docker 使用指定的 DNS 伺服器。

-g=""
    指定 Docker 執行時的 root 路徑。預設為 /var/lib/docker。

--icc=true|false
    啟用容器間通信。預設為 true。

--ip=""
    綁定連接埠時候的預設 IP 位址。預設為 0.0.0.0。

--iptables=true|false
    禁止 Docker 新增 iptables 規則。預設為 true。

--mtu=VALUE
    指定容器網路的 mtu。預設為 1500。

-p=""
    指定 daemon 的 PID 檔案路徑。預設為 /var/run/docker.pid。

-s=""
    強制 Docker 執行時使用指定的儲存驅動。

-v=true|false
    輸出版本資訊並退出。預設值為 false。

--selinux-enabled=true|false
    啟用 SELinux 支援。預設值為 false。SELinux 目前不支援 BTRFS 儲存驅動。

一張圖總結 Docker 的命令

Docker 簡介

Docker by LXC(Linux Containers)

Docker 理解為一種 Applice or Server 套件的 Sandbox , 每一個 Container 都安裝執行一種應用 , Contain 間可以建立溝通 , 其Containers 啟動 和 停止都很快 對本機資源要求不高 遠低於 VM ,實際應用實 直接把Container 當成應用軟體執行也可以!

這樣帶來以下優勢

>>快速部屬和派送:

>>更高效率資源應用

>>用容易搬遷和擴展

>>用易更新

 在 LXC 的基礎上 Docker 進行了進一步的封裝，讓使用者不需要去關心容器的管理，使得操作更為簡便。使用者操作 Docker 的容器就像操作一個快速輕量級的虛擬機一樣簡單。

下面的圖片比較了 Docker 和傳統虛擬化方式的不同之處，可見容器是在作業系統層面上實作虛擬化，直接使用本地主機的作業系統，而傳統方式則是在硬體層面實作。

python read the direct [dir ] [file] list

[Python] 取得路徑下檔案

'ss = os.listdir(" ")      

'if  os.path.isfile(ss[0]) :

'if  os.path.isdir(ss[0]):

如何利用python取得特定路徑下的檔案名稱呢？ 

其實說起來也相當簡單，os module裡已經定義好了。

先從os.listdir本身會回傳該資料夾下的所有檔案名稱，以list回傳。

再用一個 for 迴圈遍訪每個檔名，對其用os.path.isfile()判斷即可(若要取資料夾使用os.path.isdir())。

以下為範例程式碼。

import os

files = [f for f in os.listdir('.') if os.path.isfile(f)]

for f in files:

        print f

上面是個簡潔有力的寫法，他的效果等義於下列程式碼:

import os

files = []

for f in os.listdir('.'):

        if os.path.isfile(f):

                files.append(f)

for f in files:

        print f
