Deprecated Engine Features
The following list of features are deprecated in Engine. To learn more about Docker Engine's deprecation policy, see Feature Deprecation Policy.
repository:shortid image references
Deprecated In Release: v1.13
Target For Removal In Release: v1.16
repository:shortid syntax for referencing images is very little used, collides with with tag references can be confused with digest references.
docker daemon subcommand
Deprecated In Release: v1.13
Target For Removal In Release: v1.16
The daemon is moved to a separate binary (dockerd), and should be used instead.
Three argument form in docker import
Deprecated In Release: v0.6.7
Removed In Release: v1.12.0
The docker import command format 'file|URL|- [REPOSITORY [TAG]]' is deprecated since November 2013. It's no more supported.
-h shorthand for --help
Deprecated In Release: v1.12.0
Target For Removal In Release: v1.15
The shorthand (-h) is less common than --help on Linux and cannot be used
on all subcommands (due to it conflicting with, e.g. -h / --hostname on
docker create). For this reason, the -h shorthand was not printed in the
"usage" output of subcommands, nor documented, and is now marked "deprecated".
-e and --email flags on docker login
Deprecated In Release: v1.11.0
Target For Removal In Release: v1.14
The docker login command is removing the ability to automatically register for an account with the target registry if the given username doesn't exist. Due to this change, the email flag is no longer required, and will be deprecated.
Separator (:) of --security-opt flag on docker run
Deprecated In Release: v1.11.0
Target For Removal In Release: v1.14
The flag --security-opt doesn't use the colon separator(:) anymore to divide keys and values, it uses the equal symbol(=) for consistency with other similar flags, like --storage-opt.
/containers/(id or name)/copy endpoint
Deprecated In Release: v1.8.0
Removed In Release: v1.12.0
The endpoint /containers/(id or name)/copy is deprecated in favor of /containers/(id or name)/archive.
Ambiguous event fields in API
Deprecated In Release: v1.10.0
The fields ID, Status and From in the events API have been deprecated in favor of a more rich structure.
See the events API documentation for the new format.
-f flag on docker tag
Deprecated In Release: v1.10.0
Removed In Release: v1.12.0
To make tagging consistent across the various docker commands, the -f flag on the docker tag command is deprecated. It is not longer necessary to specify -f to move a tag from one image to another. Nor will docker generate an error if the -f flag is missing and the specified tag is already in use.
HostConfig at API container start
Deprecated In Release: v1.10.0
Removed In Release: v1.12.0
Passing an HostConfig to POST /containers/{name}/start is deprecated in favor of
defining it at container creation (POST /containers/create).
Docker ps 'before' and 'since' options
Deprecated In Release: v1.10.0
Removed In Release: v1.12.0
The docker ps --before and docker ps --since options are deprecated.
Use docker ps --filter=before=... and docker ps --filter=since=... instead.
Docker search 'automated' and 'stars' options
Deprecated in Release: v1.12.0
Target For Removal In Release: v1.15
The docker search --automated and docker search --stars options are deprecated.
Use docker search --filter=is-automated=... and docker search --filter=stars=... instead.
Driver Specific Log Tags
Deprecated In Release: v1.9.0
Removed In Release: v1.12.0
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: v1.8.0
Removed In Release: v1.10.0
The built-in LXC execution driver, the lxc-conf flag, and API fields have been removed.
Old Command Line Options
Deprecated In Release: v1.8.0
Removed In Release: v1.10.0
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 -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 --cpuset
docker run --networking
docker ps --since-id
docker ps --before-id
docker search --trusted
Deprecated In Release: v1.5.0
Removed In Release: v1.12.0
The single-dash (-help) was removed, in favor of the double-dash --help
docker -help
docker [COMMAND] -help
--run flag on docker commit
Deprecated In Release: v0.10.0
Removed In Release: v1.13.0
The flag --run of the docker commit (and its short version -run) were deprecated in favor
of the --changes flag that allows to pass Dockerfile commands.
Interacting with V1 registries
Version 1.9 adds a flag (--disable-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.
Docker Content Trust ENV passphrase variables name change
Deprecated In Release: v1.9.0
Removed In Release: v1.12.0
Since 1.9, Docker Content Trust Offline key has been renamed to Root key and the Tagging key has been renamed to Repository key. Due to this renaming, we're also changing the corresponding environment variables
- DOCKER_CONTENT_TRUST_OFFLINE_PASSPHRASE is now named DOCKER_CONTENT_TRUST_ROOT_PASSPHRASE
- DOCKER_CONTENT_TRUST_TAGGING_PASSPHRASE is now named DOCKER_CONTENT_TRUST_REPOSITORY_PASSPHRASE
MAINTAINER in Dockerfile
Deprecated In Release: v1.13.0
MAINTAINER was an early very limited form of LABEL which should be used instead.
