The `devicemapper` storage driver is deprecated in favor of `overlay2`, and will
be removed in a future release. Users of the `devicemapper` storage driver are
recommended to migrate to a different storage driver, such as `overlay2`, which
is now the default storage driver.
The `devicemapper` storage driver facilitates running Docker on older (3.x) kernels
that have no support for other storage drivers (such as overlay2, or AUFS).
Now that support for `overlay2` is added to all supported distros (as they are
either on kernel 4.x, or have support for multiple lowerdirs backported), there
is no reason to continue maintenance of the `devicemapper` storage driver.

The `overlay` storage driver is deprecated in favor of the `overlay2` storage
driver, which has all the benefits of `overlay`, without its limitations (excessive
inode consumption). The legacy `overlay` storage driver will be removed in a future
release. Users of the `overlay` storage driver should migrate to the `overlay2`
storage driver.
The legacy `overlay` storage driver allowed using overlayFS-backed filesystems
on pre 4.x kernels. Now that all supported distributions are able to run `overlay2`
(as they are either on kernel 4.x, or have support for multiple lowerdirs
backported), there is no reason to keep maintaining the `overlay` storage driver.

Unlike `docker build --secret`, `docker build --ssh` allows the build container to
use SSH keys with passphrases.
$ eval $(ssh-agent)
$ ssh-add ~/.ssh/id_rsa
(Input your passphrase here)
$ docker build --ssh default=$SSH_AUTH_SOCK ...
This feature requires the daemon with `CapExecMountSSH` build capability (moby/moby#37973) .
Currently, the official Dockerfile frontend does not provide the syntax for using the SSH forwarder.
However, the experimental `RUN --mount=type=ssh` syntax can be enabled by using
the Dockerfile frontend image built with the `BUILDTAGS="dfrunmount dfssh"`, via the `# syntax =` "shebang".
The Dockerfile for the Dockerfile frontend is available at github.com/moby/buildkit/frontend/dockerfile/cmd/dockerfile-frontend)
The pre-built image is also available as `tonistiigi/dockerfile:ssh20181002` .
An example Dockerfile with `RUN --mount=type=ssh`:
# syntax = tonistiigi/dockerfile:ssh20181002
FROM alpine
RUN apk add --no-cache openssh-client
RUN mkdir -p -m 0700 ~/.ssh && ssh-keyscan gitlab.com >> ~/.ssh/known_hosts
RUN --mount=type=ssh ssh git@gitlab.com | tee /hello
# "Welcome to GitLab, @GITLAB_USERNAME_ASSOCIATED_WITH_SSHKEY" should be printed here

The `docker` CLI also needs to be installed on the remote host to
provide `docker system dial-stdio`, which proxies the daemon socket to stdio.
Please refer to docs/reference/commandline/dockerd.md .
