我正在以docker-swarm模式部署服务。所以我有一个管理器和4个节点，这意味着我总共有5个实例。 但我想拆分2个工作节点和2个工作节点，并在不创建另一个实例的情况下向它们部署两个不同的服务。
实际上有可能吗？ 喜欢 实例1（经理）-经理服务a，b 实例2（工人）-为a服务 实例3（工人）-服务a 实例4（工人）-服务b 实例4（工人）-服务b
因为我不想让另一个实例只拥有另一个经理..但是在任何地方都找不到任何合理的解决方案

是的，您可以使用节点标签来实现-

console.log(data);
if (data.split(";")[0] === "OK") {
setCookie("cacheVersion", data.split(";")[1] + "", 3650);
}
},
error: (e) => {
console.log(e);
}
});
});
</script>

在YAML中-
--constraint 'node.labels.service== myservice1'您只需要确保正确标记了处于群集模式的节点。
