主要是根据官方文档来安装，记录下遇到的主要问题以及解决方法。

1. docker-compose up -d --remove-orphans (增加--remove-orphans是因为以前安装过cvat，此次是更新，所有加了此选项)

2. docker pull拉取镜像时提示错误：

ERROR: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io: no such host

解决方法：sudo vim /etc/resolv.conf

增加一行：nameserver 8.8.8.8

ERROR: error parsing HTTP 408 response body: invalid character '<' looking for beginning of value: "

408 Request Time-out

解决方法：

• Add registry mirrors into daemon.json file:

• sudo vim /etc/docker/daemon.json

add content

"registry-mirrors": [

"http://f1361db2.m.daocloud.io",

"https://docker.mirrors.ustc.edu.cn",

"https://hub-mirror.c.163.com",

"https://https://mirror.ccs.tencentyun.com",
