執行緒池ThreadPoolExecutor並行處理實現程式碼

技術標籤:dockerdocker

注意:以下所有操作都是在容器裡面

1,首先去/etc/init.d目錄下檢視你需要啟動服務的檔案,如圖:

在這裡插入圖片描述
2,在/etc目錄下建立rc.local檔案:

$ vim /etc/rc.local

並寫入以下內容然後儲存:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
# # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #寫入你需要自啟的服務,我這裡自啟了postgresql,thingsboard /etc/init.d/postgresql start /etc/init.d/thingsboard start exit 0

3,在根目錄下建立指令碼檔案,例如:

$ cd /
$ vim start.sh

將以下內容寫入start.sh檔案並儲存:

#!/bin/sh
/etc/rc.local #execute the commands in /etc/rc.local
/bin/bash

4,最好更新下映象並重啟一個新的容器測試是否成功,注意在執行docker run命令時最後要加上./start.sh,舉例:

$ sudo docker run -itd --privileged=true -p 8080:8080 -p 8779:8779 -p 8061:8061 --restart=always -v /home/thingsboard/:/home/thingsboard/ --name thingsboard thingsboard:v1 /bin/bash ./start.sh

Done!
