生成ansible Dockerfile结果错误找不到pip3

Question

• 我试图构建一个本地Dockerfile的ansible映像：
• 我从以下Docker文件中获得了以下信息：快速启动:在码头容器中配置不可用

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" ]
• 我运行这个Dockerfile的方式是: VSCODE >右键单击Dockerfile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

• 我已经成功地构建和运行了这个映像，但是最近我创建了新的git存储库并将它们克隆到我的主机上。我把这两个文件放在一个文件夹里。
• 作为构建图像的结果，我得到了以下错误：

#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
• 我尝试了docker build .和docker-compose up命令--创建容器失败
• 我试图清理我的所有容器、图像和卷并重新构建--创建容器失败了(我遵循了以下指南：在这里输入链接描述，还使用了rm命令)

那么，缺少什么或者我需要修复什么才能工作呢？

Answer 1

您的Dockerfile中有一个错误。RUN命令中的两行不能用; \或&& \分隔。

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

因此，这个错误由ansible-galaxy命令返回，该命令试图对pip3执行一些操作。
