ssh-keygen：在 Docker 中找不到命令

Question

我正在尝试在 docker 容器内运行以下命令（centos 7作为基本映像）

ssh-keygen -t rsa -N ""

我收到此错误：

ssh-keygen：找不到命令

这是Dockerfile我用来构建容器的

FROM centos:7

ENV VER "0.12.9"

RUN yum update -y && yum install wget -y && yum install unzip -y
RUN yum install epel-release -y && yum install ansible -y

RUN wget https://releases.hashicorp.com/terraform/${VER}/terraform_${VER}_linux_amd64.zip
RUN unzip terraform_${VER}_linux_amd64.zip
RUN mv terraform /usr/local/bin/  
RUN rm -rf terraform_${VER}_linux_amd64.zip

有人能帮助我吗？

ssh-keygen是OpenSSH提供的命令，需要安装它。

添加yum install openssh-clients -y到您的 Dockerfile。

FROM centos:7

ENV VER "0.12.9"

RUN yum update -y && yum install wget -y && yum install unzip -y
RUN yum install epel-release -y && yum install ansible -y && yum install openssh-clients -y

RUN wget https://releases.hashicorp.com/terraform/${VER}/terraform_${VER}_linux_amd64.zip
RUN unzip terraform_${VER}_linux_amd64.zip
RUN mv terraform /usr/local/bin/  
RUN rm -rf terraform_${VER}_linux_amd64.zip
