Discover ways to activate the Docker checkpoint characteristic for working container snapshots with this fast tutorial from knowledgeable Jack Wallen.
In a latest TechRepublic video, Jack Wallen reveals how one can allow the Docker checkpoint characteristic to take snapshots of your working containers to save lots of a state for backup or later utilization. The next is an edited transcript of his tutorial.
First, you have to add the repository for the CRIU bundle with the next command: SUDU add-apt-repository ppa:criu/ppa.
Replace APT with this command: sudo apt-get replace.
Then set up CRIU with this command: sudo apt-get set up criu -y.
Subsequent, we should allow Docker experimental options.
First, create a brand new file with the command sudo nano /and so forth/docker/daemon.json.
In that file, add the next: {"Experimental": true}. Save and shut the file.
Restart the Docker Daemon with sudo systemctl restart docker.
Deploy an NGINX container with the command docker run --name nginx-checkpoint -p 8005:80 -d nginx.
Create the checkpoint with this command: docker checkpoint create --leave-running=true nginx-checkpoint checkpoint.
