利用 Docker 搭建 基于 Ubuntu18.4 的 GoCV 环境

使用说明

# 在桌面创建 gocv_docker 目录  
cd ~/Desktop && mkdir gocv_docker && cd ~/Desktop/gocv_docker

# 创建 Dockerfile 并将下文 Dockerfile 内容copy
touch Dockerfile

# 下载go1.17版本
wget --no-check-certificate "https://go.dev/dl/go1.17.10.linux-amd64.tar.gz"

# 构建 image
docker build -t gocv4.5_ubuntu18.4_go1.17_gocv0.30.0 . 

# 运行container 并映射文件，端口
# 容器开机自动重启 refer: https://www.jianshu.com/p/36f63f57b05d
docker run -d -p 9000-9010:9000-9010 \
   -v /Users/flybird1971/docker/gocv:/home/gocv/gocv_work \
   --name gocv4.5_ubuntu18.4_go1.17_gocv0.30.0 \
   --restart=always \
   --privileged=true gocv4.5_ubuntu18.4_go1.17_gocv0.30.0  /usr/sbin/init

# 进入container 
docker exec -it gocv4.5_ubuntu18.4_go1.17_gocv0.30.0  /bin/bash

Dockerfile

默认创建 gocv 账户运行

# base image

# mac os m1芯片
# 如果非 m1芯片，可以将 --platform=linux/amd64 移除
