If it's just that you're not satisfied please don't look down!For a specific version of the issue, the search through the official website document and issue on GitHub, there is always no good answer, and the product developers do not know why not always provide a positive approach, perhaps to promote the new version,But is this really good?

This article is from the "Knowledge Forest" In the previous example, the communication between the container and the container is done through the IP address in the network, which is obviously unreasonable, because the IP address may change when the container is started, and it is also more difficult to remember. The solution to this problem is to use a network alias, the container is allowed to be alias on the network, and the alias can be directly accessed in the network, which is similar to t

five minutes to meet DockerWhat is Docker?Think of him as an ultra-lightweight virtual machine that is implemented in a novel way, which is probably the right thing to do.
