This article mainly explains "how to copy files to the host in the docker container". The explanation in the article is simple and clear and easy to learn and understand. please follow the editor's ideas to study and learn "how to copy files to the host in the docker container".

To copy files from the docker container to the host, execute the following command in the host:

Docker cp container name: the path of the file to be copied in the container should be copied to the corresponding path of the host

Suppose the name of the container is testtomcat, and the file path to be copied from the container is / usr/local/tomcat/webapps/test/js/test.js. Now copy test.js from the container to the / opt path of the host, and execute the command on the host.

Docker cp testtomcat:/usr/local/tomcat/webapps/test/js/test.js / opt

Suppose I want to copy a common.log file, then after entering the container, use the find. /-name "common.log" command to find the directory where the file is located, assuming that the search result is

. / mwbase/applogs/rtlog/OLS/common.log

Execute exit to exit the docker container. After exiting the container, you want to copy it to the / home/rhlog directory of the host and rename it to yyy.log. Then the final command is:

Docker cp 6741xxxxxxxx:/xxxx/xxx/xxx/xxxx/common.log / home/rhlog/yyy.log # Note there is no "."

As a result of the execution, you can see that the / home/rhlog directory copy gets the yyy.log, so the file is copied out.
