- **Changing the volume from within the Dockerfile**: If any build steps change the
data within the volume after it has been declared, those changes will be discarded.
- **JSON formatting**: The list is parsed as a JSON array.
You must enclose words with double quotes (`"`)rather than single quotes (`'`).
- **The host directory is declared at container run-time**: The host directory
(the mountpoint) is, by its nature, host-dependent. This is to preserve image
portability. since a given host directory can't be guaranteed to be available
on all hosts.For this reason, you can't mount a host directory from
within the Dockerfile. The `VOLUME` instruction does not support specifying a `host-dir`
parameter. You must specify the mountpoint when you create or run the container.

##### Legacy Registries ##### Legacy Registries
Enabling `--disable-legacy-registry` forces a docker daemon to only interact with registries which support the V2 protocol. Specifically, the daemon will not attempt `push`, `pull` and `login` to v1 registries. The exception to this is `search` which can still be performed on v1 registries. Operations against registries supporting only the legacy v1 protocol are
disabled by default. Specifically, the daemon will not attempt `push`,
`pull` and `login` to v1 registries. The exception to this is `search`
which can still be performed on v1 registries.
Add `"disable-legacy-registry":false` to the [daemon configuration
file](#daemon-configuration-file), or set the
`--disable-legacy-registry=false` flag, if you need to interact with
registries that have not yet migrated to the v2 protocol.
Interaction v1 registries will no longer be supported in Docker v17.12,
and the `disable-legacy-registry` configuration option will be removed.

### Specify hard limits on memory available to containers (-m, --memory)
These parameters always set an upper limit on the memory available to the container. On Linux, this
is set on the cgroup and applications in a container can query it at `/sys/fs/cgroup/memory/memory.limit_in_bytes`.
On Windows, this will affect containers differently depending on what type of isolation is used.
- With `process` isolation, Windows will report the full memory of the host system, not the limit to applications running inside the container
```powershell
docker run -it -m 2GB --isolation=process microsoft/nanoserver powershell Get-ComputerInfo *memory*
CsTotalPhysicalMemory : 17064509440
CsPhyicallyInstalledMemory : 16777216

OsFreeVirtualMemory : 17197440
OsInUseVirtualMemory : 1957488
OsMaxProcessMemorySize : 137438953344
```
- With `hyperv` isolation, Windows will create a utility VM that is big enough to hold the memory limit, plus the minimal OS needed to host the container. That size is reported as "Total Physical Memory."
```powershell
docker run -it -m 2GB --isolation=hyperv microsoft/nanoserver powershell Get-ComputerInfo *memory*
