This post will cover topic related to ‘Managing Docker Checkpoints’ with multiple docker command examples and different scenerios. So this will help you to understand the command docker and options available in it. Also this post will explain you how to use docker command.
Managing Docker Checkpoints allows you to save the state of a container and later resume it from the saved state. This is particularly useful for troubleshooting, testing, or maintaining the state of a long-running container.
Example 1: Creating a Docker checkpoint named “checkpoint1” for a running container named “mycontainer”:
docker checkpoint create mycontainer checkpoint1
To verify if the checkpoint was created, you can list all checkpoints for a container:
docker checkpoint ls mycontainer
Example 2: Restoring a container from a previously created checkpoint:
docker start --checkpoint checkpoint1 mycontainer
To verify if the container was successfully restored, you can inspect the container’s status:
docker inspect --format='{{.State.Status}}' mycontainer
Example 3: Removing a checkpoint:
docker checkpoint rm mycontainer checkpoint1
You can verify if the checkpoint was removed by listing all checkpoints again:
docker checkpoint ls mycontainer
Example 4: Creating a checkpoint and including the container’s filesystem:
docker checkpoint create --checkpoint-dir=/var/lib/docker/checkpoints --leave-running mycontainer checkpoint2
Example 5: Listing all available checkpoints across all containers:
docker checkpoint ls --all
Example 6: Inspecting details of a specific checkpoint:
docker checkpoint inspect mycontainer checkpoint1
Example 7: Exporting a checkpoint to a tarball:
docker checkpoint export mycontainer checkpoint1 > checkpoint1.tar
Example 8: Importing a checkpoint from a tarball:
docker checkpoint import mycontainer checkpoint2 < checkpoint2.tar
Example 9: Rolling back a container to a checkpoint:
docker checkpoint restore --checkpoint checkpoint1 mycontainer
Example 10: Creating a checkpoint without suspending the container:
docker checkpoint create --leave-running mycontainer checkpoint3
