問題：
通過 docker build構(gòu)建SpringBoot鏡像時出現(xiàn)如下問題：文章來源：http://www.zghlxwxcb.cn/news/detail-627712.html
[root@localhost docker]# docker build -t example:1.0.0 .

[root@localhost docker]#方案：
該問題由網(wǎng)絡(luò)不好產(chǎn)生，可以更換網(wǎng)絡(luò)環(huán)境嘗試一下，如果還是沒有解決，可以通過修改dockerfile文件FROM配置嘗試一下，如下所示：文章來源地址http://www.zghlxwxcb.cn/news/detail-627712.html
