Before the docker CLI sends the context to the docker daemon, it looks for a file named.dockerignorein the root directory of the context. If this file exists, the CLI modifies the context to exclude files and directories that match patterns in it. This helps to avoid unnecessarily sending la...
Write-intensive applications, such as database storage, are impacted by a performance overhead, particularly if pre-existing data exists in the read-only layer Docker使用存储驱动程序存储图像层,并将数据存储在容器的可写层中。删除容器后,容器的可写层不会持续存在,但适用于存储在运行时生成的短暂数据。
