建構 ansible Dockerfile 結果錯誤找不到 pip3

• 我嘗試通過本地 Dockerfile 建構 ansible 的圖像：
• 我從以下 Docker 文件中獲得：快速入門：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" ]

• 最後三行是我的補充：pip3 install "pywinrm>=0.2.2", WORKDIR /product,CMD [ "/usr/sbin/init" ]
• 我通過 VSCODE 執行此 Dockerfile > 右鍵點擊 docker-compose 文件並選擇Compose Up選項

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

• 我已經成功建構並執行了這個鏡像，但最近我創建了新的 git 儲存庫並將它們複製到我的主機。在那裡，我將這兩個文件放在一個文件夾中。
• 作為建構圖像的結果，我收到以下錯誤：

#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.     
#6 187.2
#6 187.2 Could not find pip3.

• 看起來第一個RUN命令根本沒有執行
• 我嘗試docker build .了docker-compose up命令 - 無法創建容器
• 我試圖清理我所有的容器、圖像和卷並再次建構 - 未能創建容器（我按照本指南：在此處輸入連結描述，還使用了 rm 命令）

那麼，缺少什麼或者我需要修復什麼才能使其正常工作？

您的Dockerfile. 命令中的兩行沒有用orRUN分隔。; \``&& \

ansible-galaxy collection install azure.azcollection; \
pip3 install "pywinrm>=0.2.2"

因此ansible-galaxy，嘗試對pip3.
