如何使用dockerfile将ping命令添加到我的荚中？
如何使用dockerfile将ping命令添加到我的荚中？
提问于 2022-07-03 11:46:02
这是我的Dockerfile
# Build the manager binary
FROM golang:1.17 as builder
WORKDIR /workspace
# Copy the Go Modules manifests
COPY go.mod go.mod
COPY go.sum go.sum
# cache deps before building and copying source so that we don't need to re-download as much
# and so that source changes don't invalidate our downloaded layer
RUN go mod download
# Copy the go source
COPY main.go main.go
COPY api/ api/
COPY controllers/ controllers/
COPY opt/ opt/
RUN ls -altr /workspace
RUN chmod 775 /workspace/opt
# Build
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -o manager main.go
FROM alpine as alpine
RUN apk add --no-cache bash
FROM scratch
COPY --from=alpine /lib/ld-musl-x86_64.so.1 /lib/ld-musl-x86_64.so.1
COPY --from=alpine /bin/ping ./ping
FROM registry.access.redhat.com/ubi8/ubi-minimal:latest
WORKDIR /
COPY --from=builder /workspace/manager .
COPY --from=builder /workspace/opt ./opt
RUN chgrp 0 /manager \
&& chmod g=u /manager
RUN chgrp 0 /opt \
&& chmod g=u /opt
ENTRYPOINT ["/manager","./ping"]在构建图像之后，我使用
kubectl exec -it pod/controller-manager-deploy-5748468c5f-f4xrk -n cdg -- /bin/bash登录到吊舱后，如果我运行ping命令
[root@controller-manager-deploy-5748468c5f-f4xrk /]# ping
bash: ping: command not found我收到了这条错误消息。
在这个容器中的/usr/bin文件夹中，我只能看到这些包
[root@controller-manager-deploy-5748468c5f-f4xrk bin]# ls

这基本上可以安装您想安装的任何包，您可以简单地在基本阶段或最后阶段添加运行选项，对于基于Debian/Ubuntu的映像，如下所示：
FROM base AS final
WORKDIR /
COPY --from=builder /workspace/manager .
COPY --from=builder /workspace/opt ./opt
######################
# Installing ping
RUN apt-get update
RUN apt-get install -y iputils-ping # <- change this according to your image
######################
RUN chgrp 0 /manager \
&& chmod g=u /manager
RUN chgrp 0 /opt \
&& chmod g=u /opt
ENTRYPOINT ["/manager","./ping"]根据linuxshelltips提示的这篇文章，以下是安装ping的方法：
$ sudo apt install iputils-ping [On Debian, Ubuntu and Mint]
$ sudo yum install iputils [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux]
$ sudo emerge -a net-misc/iputils [On Gentoo Linux]
$ sudo pacman -S iputils [On Arch Linux]
$ sudo zypper install iputils [On OpenSUSE] 我不知道RedHat UBI映像是基于哪个发行版的，但我猜是RHEL吗？
