docker cp ~/Downloads/dump :/dump Restore. If you specify an archive, Docker untars it in the container relative to the / (root). This will create an interactive shell that can be used to explore the Docker. By default, a temporary directory is created on the host and mounted into a container to allow storing files that together exceed the default disk size of 10GB in a container. # zcat ubuntu-web.gz | docker import - ubuntu-web The above command will create a docker image on your system.
Login to your Docker instance via docker exec -it DOCKER_CONTAINER_ID bin/bash. Before you can export a Docker container, you need to commit the changes into an image and tag it appropriately. docker import busybox.tar if we run with this command specifying repo and tag and list images, we can see those populated with the repo and tag given in the command. You can also execute into the Docker container directly by running docker run -it /bin/bash. This is a simple way of importing MySQL database in Docker.
Note: Save is used for making backup of docker images (not containers). The docker service logs command shows information logged by all containers participating in a service. When you are ready to create a container, open the APPS page and click Launch Docker Image. The command to export the containers is: docker export NAME | gzip > NAME.gz Where NAME is the name of the container to be exported. Once you have built the Docker Image with a particular Docker build context, building it again and again just to add small files or folders inside the Container might be expensive because usually, Docker Images are of very large sizes.
Docker will even try to start an imported instance which was saved with docker export. In the above example, the result of each builder is passed through the defined sequence of post-processors starting first with the docker-import post-processor which will import the artifact as a docker image.
