This article will explain in detail how the data persistence of Docker is, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

There are two main ways to persist data in a container:

Data volume (Data Volumes)

Data volume container (Data Volumes Dontainers)

Data volume

A data volume is a special directory that can be used by one or more containers and can bypass UFS (Unix File System).

Data volumes can be shared and reused between containers

Changes to the data volume will take effect immediately

Updates to data volumes do not affect mirroring

The data volume will always exist by default, even if the container is deleted

Multiple data volumes can be mounted in a container

Note: the use of data volumes is similar to mount directories or files under Linux.

Create a data volume

Example:

Docker run-name v1-volumes-from nginx-volume nginxdocker run-name v2-volumes-from nginx-volume nginx

Like this:

V1 and v2 containers can share files in the nginx-volume container.

Even if nginx-volume stops, it won't make any difference.

About how Docker data persistence is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
