16.4.2. 打包调度程序

创建包含调度程序二进制文件的容器镜像。

例如：

FROM <source-image>
ADD <path-to-binary> /usr/local/bin/kube-scheduler

将文件保存为 Dockerfile，构建镜像并将其推送到 Registry。

例如：

docker build -t <dest_env_registry_ip>:<port>/<namespace>/<image name>:<tag>
docker push <dest_env_registry_ip>:<port>/<namespace>/<image name>:<tag>

在 OpenShift Container Platform 中，为自定义调度程序创建一个部署。
