4.13. 创建安装配置文件

流程

1. 在命令行中，浏览包含 install-config.yaml 和 inventory.yaml 文件的目录。

2. 在该目录中，运行脚本来编辑 install-config.yaml 文件或手动更新该文件：

   • 要使用脚本设置值，请运行以下命令：

     $ python -c 'import os
     import sys
     import yaml
     import re
     re_os_net_id = re.compile(r"{{\s*os_net_id\s*}}")
     os_net_id = os.getenv("OS_NET_ID")
     path = "common.yaml"
     facts = None
     for _dict in yaml.safe_load(open(path))[0]["tasks"]:
         if "os_network" in _dict.get("set_fact", {}):
             facts = _dict["set_fact"]
             break
     if not facts:
         print("Cannot find `os_network` in common.yaml file. Make sure OpenStack resource names are defined in one of the tasks.")
         sys.exit(1)
     os_network = re_os_net_id.sub(os_net_id, facts["os_network"])
     os_subnet = re_os_net_id.sub(os_net_id, facts["os_subnet"])
     path = "install-config.yaml"
     data = yaml.safe_load(open(path))
     inventory = yaml.safe_load(open("inventory.yaml"))["all"]["hosts"]["localhost"]
     machine_net = [{"cidr": inventory["os_subnet_range"]}]
     api_vips = [inventory["os_apiVIP"]]
     ingress_vips = [inventory["os_ingressVIP"]]
     ctrl_plane_port = {"network": {"name": os_network}, "fixedIPs": [{"subnet": {"name": os_subnet}}]}
     if inventory.get("os_subnet6_range"): 1
         os_subnet6 = re_os_net_id.sub(os_net_id, facts["os_subnet6"])
         machine_net.append({"cidr": inventory["os_subnet6_range"]})
         api_vips.append(inventory["os_apiVIP6"])
         ingress_vips.append(inventory["os_ingressVIP6"])
         data["networking"]["networkType"] = "OVNKubernetes"
         data["networking"]["clusterNetwork"].append({"cidr": inventory["cluster_network6_cidr"], "hostPrefix": inventory["cluster_network6_prefix"]})
         data["networking"]["serviceNetwork"].append(inventory["service_subnet6_range"])
         ctrl_plane_port["fixedIPs"].append({"subnet": {"name": os_subnet6}})
     data["networking"]["machineNetwork"] = machine_net
     data["platform"]["openstack"]["apiVIPs"] = api_vips
     data["platform"]["openstack"]["ingressVIPs"] = ingress_vips
     data["platform"]["openstack"]["controlPlanePort"] = ctrl_plane_port
     del data["platform"]["openstack"]["externalDNS"]
     open(path, "w").write(yaml.dump(data, default_flow_style=False))'

     适用于双栈 (IPv4/IPv6) 环境。

流程

1. 在命令行中，浏览包含 install-config.yaml 的目录。

2. 在该目录中，运行脚本来编辑 install-config.yaml 文件或手动更新该文件：

   • 要使用脚本设置值，请运行：

     $ python -c '
     import yaml;
     path = "install-config.yaml";
     data = yaml.safe_load(open(path));
     data["compute"][0]["replicas"] = 0;
     open(path, "w").write(yaml.dump(data, default_flow_style=False))'

   • 要手动设置值，打开该文件并将 compute.<first entry>.replicas 的 值设置为 0。
