amazon-web-services - Ansible EC2 没有这样的文件或目录 : b'ssh': b'ssh'

Question

我正在尝试将 dockerized React Web 应用程序部署到 EC2，但在配置实例时仍然出现错误。已经搜索但没有找到任何东西。

使用命令部署:

ansible-playbook -vvvvv ansible/ec2_deploy.yml --user ubuntu

我在其中运行 ansible 的 Docker:

FROM node:10.23.0-alpine3.9
COPY . .
ENV PYTHONUNBUFFERED=1
RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
RUN python3 -m ensurepip
RUN pip3 install --no-cache --upgrade pip setuptools
RUN apk add --update ansible
RUN apk add 
RUN pip install boto
RUN chmod 777 get_vault_pass.sh
ENTRYPOINT [ "/bin/sh" ]

Ansible 部署:

知道哪里出了问题吗？我已经在这上面花了很长时间...由于代码太长，我被要求添加更多详细信息，这里有更多文本，大声笑

chepner 的评论很准确——您的 docker 镜像没有安装 ssh。尝试

apk add openssh-client

并且应该解决错误。
