# Bootstrap servers with kolla deploy dependencies:
# 执行之后 docker 等 依赖环境会被删除
# !!!! 类似 环境 重置.  也可以 用来 裸os 自动 安装 依赖环境
# !!!!
kolla-ansible -i ./all-in-one bootstrap-servers

# gen pwd
# Do pre-deployment checks for hosts:
# Finally proceed to actual OpenStack deployment:
kolla-genpwd
kolla-ansible -i ./all-in-one prechecks

# 生成 授权 文件
kolla-ansible post-deploy

# pull images  if  deploy net is not fast
# 如果使用 私有 镜像源 也可以跳过这一步
kolla-ansible pull


# 停止 continer , 运行状态 占用 内存 太高.
kolla-ansible stop  --yes-i-really-really-mean-it
