Types of Docker Volumes
- Named Volumes: These are created and managed by Docker, and can be used by specifying a name. They are stored in Docker’s storage area and can be shared between containers.
- Anonymous Volumes: These are created when a container is started without specifying a volume name. They are useful for temporary data storage.
- Host Volumes (Bind Mounts): These are directories on the host machine mounted into the container.
How to Remove Docker Volumes
Docker volumes are a crucial component in Docker that are used to manage persistent data for containerized applications. They are storage units that can be attached to one or more containers, allowing data to be shared and persist beyond the lifecycle of a single container. They are managed by Docker and are stored outside the container’s writable layer.
They are prominently used for:
- Storing database data to ensure persistence across container restarts.
- Storing logs outside containers
- Mounting source code directories for live development etc.
