我在构建 go proyect 时遇到问题,我使用 golang:alpine 构建并将结果复制到 oraclelinux:7-slim 问题是当我执行 docker 映像时结果是错误
"standard_init_linux.go:211: exec user process caused "no such file or directory"".
我尝试通过示例“FROM golang:1.14 as builder”使用其他基础镜像构建并在 oraclelinux:7-slim 中执行,结果令人满意。
我需要在 oraclelinux:7-slim 中执行,因为需要使用 Oracle Instant 客户端连接数据库。
我想用 Alpine 构建,因为 golang:1.14 非常重。
附上dockerfile
