Can docker containers be exported? Yes, one of the advantages of docker is portability, and docker containers can import and export at will.

First, we create a container, and then do some basic configuration. Here, take nginx as an example, create a nginx container. Then launch and upload a local index.html file to the container. The specific steps are as follows:

First, create an index.html file with the following content, and set the path at will. Here is / usr/docker/nginx, and the content is as follows:

Test page

Hello Docker!

After the creation is complete, run a nginx container with the following command:

Docker run-itd-- name nginx-p 80:80 nginx

Finally, copy the local web page into the container with the following command:

Docker cp / usr/docker/nginx/index.html nginx:/usr/share/nginx/html/

At this point, visit ip:80.

After the above operation is complete, you can export the container through the export command:

Docker export container id/ name > path to export
