使用Docker部署EdgeX
老師安排我搞邊緣計算,搞了很久都沒能明白邊緣計算是什麼,甚至對其興趣不大,前一陣弄好了lorawan閘道器,該做閘道器內部的邊緣計算了,發現自己已經慢慢地學了進去,總是想要把這個東西搞完善。我都要著手準備考研了,居然還在這裡搞這個,執念太深。後繼無人啊,自己的孩子總怕沒人好好養。
這幾天查閱文獻的時候發現了這個邊緣計算框架,這個看起來不是很容易上手,國內的EMQX也在搞相關的東西,他那一套是Neutron+NanoMQ+eKuiper+EMQX,不過感覺會變成收費產品,於是還是瞭解瞭解這個從2017年就已經有了的開源專案EdgeX Foundry。
弄了三天,終於弄好了。這幾天看了幾個舊版的EdgeX相關部落格,有的缺少一些docker-compose安裝的內容,有的已經不再適用新版本,使用curl命令快速體驗EdgeX的方法總是會受到網路的限制,經常433拒絕連線。於是選擇了官方文件中的“Getting Started with Docker”
多說無益,正文開始
硬體環境:Raspberry 4B
軟體環境:Linux raspberrypi 5.10.17-v8+ #1414 SMP PREEMPT Fri Apr 30 13:23:25 BST 2021 aarch64 GNU/Linux
系統映象在下文的相關資料中,如果不會燒寫映象,可以找一找相關部落格,燒寫器和映象在下文中已經一併給出
安裝docker&docker-compose
安裝docker-ce
新增GPG金鑰
curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/raspbian/gpg | sudo apt-key add -
獲取安裝包
wget https://download.docker.com/linux/debian/dists/buster/pool/edge/arm64/containerd.io_1.3.7-1_arm64.deb
wget https://download.docker.com/linux/debian/dists/buster/pool/edge/arm64/docker-ce-cli_19.03.13~3-0~debian-buster_arm64.deb

設定docker映象
sudo nano /etc/docker/daemon.json
填入內容
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
過載
sudo systemctl daemon-reload
sudo systemctl restart docker
驗證安裝
docker -v
Docker version 19.03.13, build 4484c46
安裝docker-compose
sudo apt install python3-pip # 安裝pip3
sudo apt install libffi-dev # 安裝libffi
pip3 install docker-compose # 安裝docker-compose
為安裝的docker-compose新增環境變數
nano ~/.zshrc
填入
export PATH="${PATH}:/home/pi/.local/bin"
載入
source ~/.zshrc
驗證安裝
docker-compose -v
docker-compose version 1.29.2, build unknown
部署EdgeX
克隆edgexfoundry/edgex-compose
git clone https://github.com/edgexfoundry/edgex-compose.git
如果git clone時出現超時和斷開連線的情況,可以看下文相關資料中的Github克隆加速
切換分支
cd edgex-compose/
git checkout jakarta
生成docker-compose.yml
cd compose-builder/
make gen no-secty arm64 ds-mqtt asc-mqtt asc-ex-mqtt mqtt-broker mqtt-bus
拉取映象
docker-compose pull
出現Permission Denied
sudo chmod 777 /var/run/docker.sock
啟動Edgex
docker-compose up -d # -d可選,選擇是否後臺執行(無執行資訊)
檢視是否啟動
docker-compose ps
訪問EdgeX Console進入EdgeXUI介面
關閉Edgex
docker-compose down
Question
本人遇到了幾個問題,還望可以得到解答
1.啟用了EdgeX的安全模式後,不知道如何獲取EdgeX UI介面的token
按照官方文件的操作會報錯
有的時候時container衝突,有的時本地ip172.23.0.5:8443拒絕連線,最後的錯誤是container"/edgex-security-bootstrapper" Conflict,也就是容器衝突,可是用docker ps和docker-compose ps也看不到衝突的那個容器的id

2.如何配置連線真實的MQTT南向裝置?
3.為什麼使用64位raspbian之後,它的瀏覽器只要是開啟一個網頁就會卡頓?其他的命令列一類的東西都不卡

安裝uuidgen

EdgeX啟用安全模式(make gen
時不新增no-secty
選項)時,可能會用到,至今不會使用EdgeX UI介面的Token生成
