This article shows you data-packed volume container, the content is concise and easy to understand, can definitely make your eyes bright, through the detailed introduction of this article, I hope you can get something.

In the final analysis, the data of volume container is still in host. Is there a way to put the data completely into volume container and share it with other containers at the same time?

Of course, we usually call this kind of container data-packed volume container. The principle is to package the data into a mirror and then share it through docker managed volume.

We use the following Dockerfile to build the image:

ADD adds static files to the container directory / usr/local/apache2/htdocs.

VOLUME is equivalent to-v and is used to create a docker managed volume,mount point of / usr/local/apache2/htdocs, because this directory is the directory added by ADD, so the existing data is copied to volume.

New build image datapacked:

Because the VOLUME directive is already used in Dockerfile, you don't need to specify the mount point of volume here. Start the httpd container and use data-packed volume container

The container can read the data in volume correctly. Data-packed volume container is self-contained, does not rely on host to provide data, has a strong portability, and is very suitable for scenarios that only use static data, such as application configuration information, web server static files, and so on.
