去SAP官网下载nwrfc750P_7-70002752.zip 然后解压后，打包成nwrfcsdk.tar.gz
# 准备SAP依赖
unzip -d nwrfcsdk nwrfc750P_7-70002752.zip
tar -czf nwrfcsdk.tar.gz nwrfcsdk
# 构建镜像
docker build -t dongdavid/gosap:latest .
# 启动容器
docker run -d -it --name gosap -p 8000:8080 -v $PWD:/data dongdavid/gosap:latest bash在新版本的go中(我用的是1.15.6)，使用go get加载sap/gorfc这个包的时候会出现一个错误提示,它会导致镜像构建失败,所以在Dockerfile中我使用的是dongdavid/gorfc来替代sap/gorfc
