| - | ===== Docker Volumes ===== | + | ===== Persistent Data with Docker Volumes ===== |
| - | Persistent | + | You need to do this when you want to store data/ |
| + | You have three types of Docker volumes, i.e. | ||
| + | < | ||
| + | # A defined volume (Note: I am only showing the -v flag). | ||
| + | docker run -v [host folder]: | ||
| + | docker run -v / | ||
| + | |||
| + | # An anonymous volume (Note: I am only showing the -v flag and I don't necessarily know where the persistent storage is kept but should be below / | ||
| + | docker run -v [container folder] | ||
| + | docker run -v / | ||
| + | |||
| + | # A named volume (Note: I am only showing the -v flag, again I may not know where the storage is kept but should be below / | ||
