26. We are Humanizing Interaction through Artificial Intelligence Volume …stored within a directory on the Docker host…
27. We are Humanizing Interaction through Artificial Intelligence Use Case - Sharing data among multiple running containers. E.g. environment variable configuration - Store data on a remote host or cloud providers - Back up, restore, or migrate data from one Docker host to another
28. We are Humanizing Interaction through Artificial Intelligence Live-Update with Docker Volume
29. We are Humanizing Interaction through Artificial Intelligence What is Live Update?
30. We are Humanizing Interaction through Artificial Intelligence Update the application configuration inside container without having restart the container
31. We are Humanizing Interaction through Artificial Intelligence Why Do We Need Live Update?
32. We are Humanizing Interaction through Artificial Intelligence You need to change the value of your application’s configs …without downtime
33. We are Humanizing Interaction through Artificial Intelligence The Problem is…
34. We are Humanizing Interaction through Artificial Intelligence Container can’t update the environment variable after it run …same with the running application…
35. We are Humanizing Interaction through Artificial Intelligence …so how do we do it?
36. We are Humanizing Interaction through Artificial Intelligence Make your application read environment variables from file …you need file watcher tho…
37. We are Humanizing Interaction through Artificial Intelligence Creating Docker Volume
38. We are Humanizing Interaction through Artificial Intelligence Using `docker run` docker run —name container-name -v </path/on/host>:</path/on/container>
39. We are Humanizing Interaction through Artificial Intelligence Using `docker volume` docker volume create <volume-name>
40. We are Humanizing Interaction through Artificial Intelligence Using Docker Volume Name docker run —name container-name -v <volume-name>:</path/on/container> docker volume create <volume-name>
