流程

1. 刷新 API 令牌：

   $ source refresh-token

2. 获取主机 ID：

   $ curl -s -X GET "https://api.openshift.com/api/assisted-install/v2/clusters/$CLUSTER_ID" \
   --header "Content-Type: application/json" \
     -H "Authorization: Bearer $API_TOKEN" \
   | jq '.host_networks[].host_ids'

3. 对于使用 z/VM 的 IBM Z (s390x)安装，需要额外的内核参数。

   1. 要检索匹配节点的 hostID，请运行以下命令：

      curl https://api.openshift.com/api/assisted-install/v2/infra-envs/$INFRA_ENV_ID/hosts -H "Authorization: Bearer ${API_TOKEN}" | jq '.[]|[.id,.requested_hostname] | join("|")'

   2. 要指定所需的内核参数，请运行以下命令：

      curl https://api.stage.openshift.com/api/assisted-install/v2/infra-envs/${INFRA_ENV_ID}/hosts/$1/installer-args \
      -X PATCH \
      -H "Authorization: Bearer ${API_TOKEN}" \
      -H "Content-Type: application/json" \
      -d '
      {
      "args": [
      "--append-karg", "rd.neednet=1",
      "--append-karg", "ip=10.14.6.3::10.14.6.1:255.255.255.0:master-0.boea3e06.lnxero1.boe:encbdd0:none",
      "--append-karg", "nameserver=10.14.6.1",
      "--append-karg", "ip=[fd00::3]::[fd00::1]:64::encbdd0:none",
      "--append-karg", "nameserver=[fd00::1]",
      "--append-karg", "zfcp.allow_lun_scan=0",
      "--append-karg", "rd.znet=qeth,0.0.bdd0,0.0.bdd1,0.0.bdd2,layer2=1",
      "--append-karg", "rd.dasd=0.0.5235"
      ]
      }
      ' | jq

      注意

      每个主机可能具有特定的内核参数。

      输出示例

      [
        "1062663e-7989-8b2d-7fbb-e6f4d5bb28e5"
      ]

4. 修改主机：

   $ curl https://api.openshift.com/api/assisted-install/v2/infra-envs/${INFRA_ENV_ID}/hosts/<host_id> \

   -X PATCH \
   -H "Authorization: Bearer ${API_TOKEN}" \
   -H "Content-Type: application/json" \
   -d '
       {
         "host_role":"worker"
         "host_name" : "worker-1"
       }
   ' | jq
