红帽全球峰会4.2. 在基础架构节点上部署 Quay
默认情况下，在使用 Operator 部署 registry 时，Quay 相关的 pod 会放在任意 worker 节点上。OpenShift Container Platform 文档演示了如何使用机器集将节点配置为仅托管基础架构组件（请参阅 https://docs.openshift.com/container-platform/4.7/machine_management/creating-infrastructure-machinesets.html）。
如果不使用 OCP MachineSet 资源来部署 infra 节点，本节演示了如何为基础架构手动标记和污点节点。
一旦配置了基础架构节点，可以手动或使用机器集，然后使用节点选择器和容限控制这些节点上的 Quay pod 放置。
4.2.1. 基础架构使用的标签和污点节点
复制链接链接已复制到粘贴板!
在这个示例中，有三个 master 节点和六个 worker 节点：
为基础架构标记最终三个 worker 节点：
oc label node --overwrite user1-jcnp6-worker-c-pwxfp.c.quay-devel.internal node-role.kubernetes.io/infra= oc label node --overwrite user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal node-role.kubernetes.io/infra= oc label node --overwrite user1-jcnp6-worker-d-m9gg4.c.quay-devel.internal node-role.kubernetes.io/infra=
$ oc label node --overwrite user1-jcnp6-worker-c-pwxfp.c.quay-devel.internal node-role.kubernetes.io/infra=
$ oc label node --overwrite user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal node-role.kubernetes.io/infra=
$ oc label node --overwrite user1-jcnp6-worker-d-m9gg4.c.quay-devel.internal node-role.kubernetes.io/infra=
现在，当您列出集群中的节点时，最后 3 个 worker 节点会添加 infra 角色：
将 infra 节点分配为 worker 时，用户工作负载可能会意外地分配给 infra 节点。要避免这种情况，您可以将污点应用到 infra 节点，然后为您要控制的 pod 添加容限。
