Join Arthur Ulfeldt for an in-depth discussion in this video Volumes, part of Learning Docker.
- Let's talk about sharing data between containers…and between containers and hosts.…Docker offers this feature called volumes.…Volumes are sort of like shared folders,…they're virtual discs that you can store data in…and share them between the containers and between containers…and the host, or both.…So they have two main varieties of volumes,…these virtual discs, available within Docker.…You've got persistent ones; you can put data there…and it will be available on the host, and when the container…goes away, the data will still be there.…
And you have ephemeral volumes; these exist as long…as the container is using them, but when no container…is using them, they evaporate.…So they're sort of ephemeral, they'll stick around…as long as they're being used, but they're not permanent.…These are not part of images, no part of volumes…will be included when you download an image, and no part…of volumes is gonna be involved if you upload an image.…They're for your local data, local to this host.…So first, let's talk about sharing data…
