有谁能够帮我？几天前，这个 docker-compose 文件在容器内可用 docker 命令为我工作，但现在它抛出：docker: not foundinside。

主机上的 docker 守护进程开启/usr/local/bin/docker。这是一个麦克。

任何想法？你能帮我在你们的人身上试试这个吗？谢谢

Dockerfile服务remote_host如下：

RUN yum install -y openssh-server

RUN useradd remote_user && \
    echo "1234" | passwd remote_user --stdin && \
    mkdir /home/remote_user/.ssh && \
    chmod 700 /home/remote_user/.ssh

COPY remote-key.pub /home/remote_user/.ssh/authorized_keys

RUN chown remote_user:remote_user -R /home/remote_user && \
    chmod 600 /home/remote_user/.ssh/authorized_keys

RUN /usr/sbin/sshd-keygen > /dev/null 2>&1

RUN yum install -y mysql

RUN yum install -y epel-release && \
    yum install -y python-pip && \
    pip install --upgrade pip && \
    pip install awscli

# CMD /usr/sbin/sshd-keygen -D
CMD tail -f /dev/null
