1.[openstack.kolla.docker : Install docker rpm gpg key]

        这个问题是docker的连接问题，重新执行一遍不能解决的话，可以试一下换docker的yum源。

# 更换docker源为国内镜像源
sudo tee /etc/yum.repos.d/docker.repo > /dev/null << 'EOF'

2.[openstack.kolla.docker : Install packages]

TASK [openstack.kolla.docker : Install packages] *****************************************************************
[ERROR]: Task failed: Module failed: Failed to download packages: docker-ce-cli-1:29.2.1-1.el10.x86_64: Cannot download, all mirrors were already tried without success

        这个是安装docker-ce包失败，应该是docker源的重定向太多次导致的，可以手动安装后再进行重试。

 yum install docker-ce-rootless-extras-29.2.1-1.el10.x86_64

tips：拉取镜像比较慢的情况下可以提前设置docker镜像加速

sudo tee /etc/docker/daemon.json > /dev/null << 'EOF'
{
    "registry-mirrors": [
        "https://docker.xuanyuan.me",
        "https://hub.rat.dev",
        "https://docker.m.daocloud.io"
    ]
