# Deprecated Features

The following list of features are deprecated.

### Command line short variant options
**Deprecated In Release: v1.9**

**Target For Removal In Release: v1.11**

The following short variant options are deprecated in favor of their long
variants:

    docker run -c (--cpu-shares)

### Driver Specific Log Tags
**Deprecated In Release: v1.9**

**Target For Removal In Release: v1.11**

Log tags are now generated in a standard way across different logging drivers.
Because of which, the driver specific log tag options `syslog-tag`, `gelf-tag` and
`fluentd-tag` have been deprecated in favor of the generic `tag` option.

    docker --log-driver=syslog --log-opt tag="{{.ImageName}}/{{.Name}}/{{.ID}}"

### LXC built-in exec driver
**Deprecated In Release: v1.8**

**Target For Removal In Release: v1.10**

The built-in LXC execution driver is deprecated for an external implementation.
The lxc-conf flag and API fields will also be removed.

### Old Command Line Options
**Deprecated In Release: [v1.8.0](/release-notes/#docker-engine-1-8-0)**

**Target For Removal In Release: v1.10**

The flags `-d` and `--daemon` are deprecated in favor of the `daemon` subcommand:

    docker daemon -H ...

The following single-dash (`-opt`) variant of certain command line options
are deprecated and replaced with double-dash options (`--opt`):

    docker attach -nostdin
    docker attach -sig-proxy
    docker build -no-cache
    docker build -rm
    docker commit -author
    docker commit -run
    docker events -since
    docker history -notrunc
    docker images -notrunc
    docker inspect -format
    docker ps -beforeId
    docker ps -notrunc
    docker ps -sinceId
    docker rm -link
    docker run -cidfile
    docker run -cpuset
    docker run -dns
    docker run -entrypoint
    docker run -expose
    docker run -link
    docker run -lxc-conf
    docker run -n
    docker run -privileged
    docker run -volumes-from
    docker search -notrunc
    docker search -stars
    docker search -t
    docker search -trusted
    docker tag -force

The following double-dash options are deprecated and have no replacement:

    docker run --networking
    docker ps --since-id
    docker ps --before-id
    docker search --trusted

### Auto-creating missing host paths for bind mounts
**Deprected in Release: v1.9**

**Target for Removal in Release: 1.11**

When creating a container with a bind-mounted volume-- `docker run -v /host/path:/container/path` --
docker was automatically creating the `/host/path` if it didn't already exist.

This auto-creation of the host path is deprecated and docker will error out if
the path does not exist.

### Interacting with V1 registries

Version 1.9 adds a flag (`--no-legacy-registry=false`) which prevents the docker daemon from `pull`, `push`, and `login` operations against v1 registries.  Though disabled by default, this signals the intent to deprecate the v1 protocol.
