How to copy files from host to Docker container?

Question

I am trying to build a backup and restore solution for the Docker containers that we work with.

I have Docker base image that I have created, ubuntu:base

Answer 1

docker cp SRC_PATH CONTAINER_ID:DEST_PATH

For example, I want to copy my file xxxx/download/jenkins to tomcat

I start to get the id of the container Tomcat

docker ps

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
63686740b488        tomcat              "catalina.sh run"   12 seconds ago      Up 11 seconds       0.0.0.0:8080->8080/tcp   peaceful_babbage
