Apache Mesos如何处理自定义资源？(How custom resources are handled by Apache Mesos?)

我想将具有连接池的mesos代理程序配置为具有10个连接的自定义资源。 在此之后，我假设连接将成为Mesos Offer的一部分。 我也明白，Mesos不关心自定义资源的隔离。

我的问题是

我提供了1个连接以及其他资源。 如果我接受这个提议，那么这个奴隶的连接数会减少到9。 只有在运行任务完成/死亡后，连接数才会再次变为10？

我提供了1个连接以及其他资源。 我接受了该提议，并且在TaskInfo中我没有将连接添加为资源。 这仍然会使我的连接数减少1或连接数是否相同？

I want to configure mesos agent with connection pool as custom resource with 10 connections. After this, I assume connection will be a part of Mesos Offer. I also understand that Mesos does not take care of isolation of custom resources.

My questions are

I am offered 1 connection along with other resources. If I accept the offer, will that reduce connection count to 9 for that slave. Will number of connections will be 10 again only after running task is finished/killed ?

I am offered 1 connection along with other resources. I accepted the offer and in TaskInfo I did not add connection as resource. Will that still make my connections reduce by 1 or number of connections will be same ?

最满意答案

是的，只有当您将连接指定为标量时才会减少。 如果您没有明确声明资源，则不会减去任何内容。

看看属性资源文档

Yes it will be reduced but only if you specify connections as a scalar. If you don't explicitly declare resources nothing will be subtracted.

Take a look at attributes-resources docs
