mk_openwrt_dockerimg.sh

#!/bin/bash

# 用法：
# 本机必须安装并运行docker服务
# 把编译好的　openwrt-armvirt-64-default-rootfs.tar.gz 放到 ./src2/，或./, 再运行本脚本
#
# 脚本可以代入2个参数：　          [img_name]              [tag]
# 例如：./mk_openwrt_dockerimg.sh  myname/openwrt-aarch64  latest
# 如果不填命令行参数的话，默认镜像名称是　unifreq/openwrt-aarch64:latest
#
# build成功后，用 docker images可以看到生成的镜像
# 并且会打包成本地镜像： ${OUTDIR}/docker-img-openwrt-aarch64-${TAG}.gz (可以用docker loader 命令导入)
