总结
dfimage
- 如果想要自己构建
whaler
镜像,whaler
的github
项目里面也提供了Dockerfile
,只需要下载好whaler
的源码包,稍稍修改一下就可以构建了 - 已经构建好的镜像,也可以直接拿来用
- pegleg/whaler
- alpine/dfimage
- 想自己构建一波的,可以看下面的内容,想快速使用的,可以直接跳到下面的
使用 dfimage 或 whaler
构建 whaler 镜像
wget https://github.com/P3GLEG/Whaler/archive/refs/heads/master.zip
unzip master.zip
vim Dockerfile
FROM golang:1.14.4 AS builder
# 官方这里的 ADD 本地路径直接写了 ./ 所以会有问题,
## 只需要改成解压出来的目录名称就可以了,后面的都可以不做修改
ADD ./Whaler-master /root/whaler_build
WORKDIR /root/whaler_build
RUN export CGO_ENABLED=0 && go build .
RUN cp whaler /root/whaler
FROM alpine:3.12.0
WORKDIR /root/
COPY --from=builder /root/whaler .
ENTRYPOINT ["./whaler"]
nerdctl build -t whaler:latest .
使用 dfimage 或 whaler
docker 的方式
alias dfimage="docker run -t --rm -v /var/run/docker.sock:/var/run/docker.sock:ro alpine/dfimage"
alias whaler="docker run -t --rm -v /var/run/docker.sock:/var/run/docker.sock:ro pegleg/whaler"
dfimage nginx:1.16
whaler nginx:1.16
