使用Docker部署EdgeX
老师安排我搞边缘计算,搞了很久都没能明白边缘计算是什么,甚至对其兴趣不大,前一阵弄好了lorawan网关,该做网关内部的边缘计算了,发现自己已经慢慢地学了进去,总是想要把这个东西搞完善。我都要着手准备考研了,居然还在这里搞这个,执念太深。后继无人啊,自己的孩子总怕没人好好养。
这几天查阅文献的时候发现了这个边缘计算框架,这个看起来不是很容易上手,国内的EMQX也在搞相关的东西,他那一套是Neutron+NanoMQ+eKuiper+EMQX,不过感觉会变成收费产品,于是还是了解了解这个从2017年就已经有了的开源项目EdgeX Foundry。
弄了三天,终于弄好了。这几天看了几个旧版的EdgeX相关博客,有的缺少一些docker-compose安装的内容,有的已经不再适用新版本,使用curl命令快速体验EdgeX的方法总是会受到网络的限制,经常433拒绝连接。于是选择了官方文档中的“Getting Started with Docker”
多说无益,正文开始
硬件环境:Raspberry 4B
软件环境:Linux raspberrypi 5.10.17-v8+ #1414 SMP PREEMPT Fri Apr 30 13:23:25 BST 2021 aarch64 GNU/Linux
系统镜像在下文的相关资料中,如果不会烧写镜像,可以找一找相关博客,烧写器和镜像在下文中已经一并给出
安装docker&docker-compose
安装docker-ce
添加GPG密钥
curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/raspbian/gpg | sudo apt-key add -
获取安装包
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 wget https://download.docker.com/linux/debian/dists/buster/pool/edge/arm64/docker-ce_19.03.13~3-0~debian-buster_arm64.deb
设置docker镜像
sudo nano /etc/docker/daemon.json
填入内容
{ "registry-mirrors": ["http://hub-mirror.c.163.com"] }
重载
sudo systemctl daemon-reload sudo systemctl restart docker
验证安装
docker -v Docker version 19.03.13, build 4484c46
安装docker-compose
sudo apt install python3-pip # 安装pip3 sudo apt install libffi-dev # 安装libffi pip3 install docker-compose # 安装docker-compose
为安装的docker-compose添加环境变量
nano ~/.zshrc
填入
export PATH="${PATH}:/home/pi/.local/bin"
加载
source ~/.zshrc
验证安装
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时出现超时和断开连接的情况,可以看下文相关资料中的Github克隆加速
切换分支
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
拉取镜像
docker-compose pull
出现Permission Denied
sudo chmod 777 /var/run/docker.sock
启动Edgex
docker-compose up -d # -d可选,选择是否后台运行(无运行信息)
查看是否启动
docker-compose ps
访问EdgeX Console进入EdgeXUI界面
关闭Edgex
docker-compose down
Question
本人遇到了几个问题,还望可以得到解答
1.启用了EdgeX的安全模式后,不知道如何获取EdgeX UI界面的token
按照官方文档的操作会报错
有的时候时container冲突,有的时本地ip172.23.0.5:8443拒绝连接,最后的错误是container"/edgex-security-bootstrapper" Conflict,也就是容器冲突,可是用docker ps和docker-compose ps也看不到冲突的那个容器的id

2.如何配置连接真实的MQTT南向设备?
3.为什么使用64位raspbian之后,它的浏览器只要是打开一个网页就会卡顿?其他的命令行一类的东西都不卡

docker-compose up 时 Permission denied
相关资料
安装uuidgen
sudo apt-get install uuid-runtime
EdgeX启用安全模式(make gen
时不添加no-secty
选项)时,可能会用到,至今不会使用EdgeX UI界面的Token生成
最后
如果本文章有任何错误还请指正,最后几个问题,希望可以得到高人指点,谢谢!
