Export

A company's security policy specifies that development and production containers must run on separate nodes in a given Swarm cluster.

Can this be used to schedule containers to meet the security policy requirements?

Solution: node affinities

A.

Yes

Answers
A.

Yes

B.

No

Answers
B.

No

Suggested answer: A

Explanation:

They provide granular control over where pods (or in this case, containers) are scheduled, based on the labels of the nodes1. In the context of Docker Swarm, this means that you could use node affinities to ensure that development and production containers are scheduled on separate nodes, thus meeting the company's security policy requirements12345.
