构建 ansible Dockerfile 结果错误找不到 pip3

• 我尝试通过本地 Dockerfile 构建 ansible 的图像：
• 我从以下 Docker 文件中获得：快速入门：在 Docker 容器中配置 Ansible

FROM centos:7

RUN yum check-update; \
    yum install -y gcc libffi-devel python3 epel-release; \
    yum install -y python3-pip; \
    yum install -y wget; \
    yum clean all

RUN pip3 install --upgrade pip; \
    pip3 install "ansible"; \
    wget -q https://raw.githubusercontent.com/ansible-collections/azure/dev/requirements-azure.txt; \
    pip3 install -r requirements-azure.txt; \
    rm requirements-azure.txt; \
    ansible-galaxy collection install azure.azcollection
    pip3 install "pywinrm>=0.2.2" 

WORKDIR /product

CMD [ "/usr/sbin/init" ]

• 最后三行是我的补充：pip3 install "pywinrm>=0.2.2", WORKDIR /product,CMD [ "/usr/sbin/init" ]
• 我通过 VSCODE 运行此 Dockerfile > 右键单击​​ docker-compose 文件并选择Compose Up选项

version: '2'
services:
  ansible:
    container_name: ansible
    hostname: ansible
    image: ansible
    build:
      context: .
      dockerfile: Dockerfile
    volumes: 
      - ../../../../../../../:/product
    dns:
      - 200.0.10.100

• 我已经成功构建并运行了这个镜像，但最近我创建了新的 git 存储库并将它们克隆到我的主机。在那里，我将这两个文件放在一个文件夹中。
• 作为构建图像的结果，我收到以下错误：

#6 187.2 ERROR! Neither the collection requirement entry key 'name', nor 'source' point to a concrete resolvable collection artifact. Also 'name' is not an FQCN. A valid collection name must be in the format <namespace>.<collection>. Please make sure that the namespace and the collection name  contain characters from [a-zA-Z0-9_] only.

• 看起来第一个RUN命令根本没有执行
• 我尝试docker build .了docker-compose up命令 - 无法创建容器
• 我试图清理我所有的容器、图像和卷并再次构建 - 未能创建容器（我按照本指南：在此处输入链接描述，还使用了 rm 命令）

那么，缺少什么或者我需要修复什么才能使其正常工作？
