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参考
