The following list of features are deprecated in Engine. To learn more about Docker Engine's deprecation policy, see Feature Deprecation Policy.
Deprecated in Release: v18.06.0
The namespaces com.docker.*, io.docker.*, and org.dockerproject.* in engine labels were always documented to be reserved, but there was never any enforcement.
Usage of these namespaces will now cause a warning in the engine logs to discourage their use, and will error instead in 18.12 and above.
service create and service updateDeprecated In Release: v17.05.0
Disabled by default in release: v17.10
Docker 17.05.0 added an optional --detach=false option to make the docker service create and docker service update work synchronously. This option will be enabled by default in Docker 17.10, at which point the --detach flag can be used to use the previous (asynchronous) behavior.
The default for this option will also be changed accordingly for docker service rollback and docker service scale in Docker 17.10.
-g and --graph flags on dockerdDeprecated In Release: v17.05.0
The -g or --graph flag for the dockerd or docker daemon command was used to indicate the directory in which to store persistent data and resource configuration and has been replaced with the more descriptive --data-root flag.
These flags were added before Docker 1.0, so will not be removed, only hidden, to discourage their use.
Deprecated In Release: v1.13.0
Target For Removal In Release: v17.12
When inspecting a container, NetworkSettings contains top-level information about the default (“bridge”) network;
EndpointID, Gateway, GlobalIPv6Address, GlobalIPv6PrefixLen, IPAddress, IPPrefixLen, IPv6Gateway, and MacAddress.
These properties are deprecated in favor of per-network properties in NetworkSettings.Networks. These properties were already “deprecated” in docker 1.9, but kept around for backward compatibility.
Refer to #17538 for further information.
filter param for /images/json endpointDeprecated In Release: v1.13.0
Target For Removal In Release: v17.12
The filter param to filter the list of image by reference (name or name:tag) is now implemented as a regular filter, named reference.
repository:shortid image referencesDeprecated In Release: v1.13.0
Removed In Release: v17.12
The repository:shortid syntax for referencing images is very little used, collides with tag references, and can be confused with digest references.
Support for the repository:shortid notation to reference images was removed in Docker 17.12.
docker daemon subcommandDeprecated In Release: v1.13.0
Removed In Release: v17.12
The daemon is moved to a separate binary (dockerd), and should be used instead.
Deprecated In Release: v1.13.0
Removed In Release: v17.12
When setting duplicate keys with conflicting values, an error will be produced, and the daemon will fail to start.
MAINTAINER in DockerfileDeprecated In Release: v1.13.0
MAINTAINER was an early very limited form of LABEL which should be used instead.
Deprecated In Release: v1.13.0
Target For Removal In Release: v17.12
API versions should be supplied to all API calls to ensure compatibility with future Engine versions. Instead of just requesting, for example, the URL /containers/json, you must now request /v1.25/containers/json.
d_type support for overlay/overlay2Deprecated In Release: v1.13.0
Removed In Release: v17.12
The overlay and overlay2 storage driver does not work as expected if the backing filesystem does not support d_type. For example, XFS does not support d_type if it is formatted with the ftype=0 option.
Starting with Docker 17.12, new installations will not support running overlay2 on a backing filesystem without d_type support. For existing installations that upgrade to 17.12, a warning will be printed.
Please also refer to #27358 for further information.
docker importDeprecated 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 --helpDeprecated In Release: v1.12.0
Target For Removal In Release: v17.09
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 loginDeprecated In Release: v1.11.0
Removed In Release: v17.06
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.
:) of --security-opt flag on docker runDeprecated In Release: v1.11.0
Target For Removal In Release: v17.06
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 endpointDeprecated 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.
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 tagDeprecated 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.
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).
--before and --since flags on docker psDeprecated 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.
--automated and --stars flags on docker searchDeprecated in Release: v1.12.0
Target For Removal In Release: v17.09
The docker search --automated and docker search --stars options are deprecated. Use docker search --filter=is-automated=... and docker search --filter=stars=... instead.
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.
{% raw %} docker --log-driver=syslog --log-opt tag="{{.ImageName}}/{{.Name}}/{{.ID}}" {% endraw %}
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.
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 commitDeprecated 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.
Disabled By Default In Release: v17.06
Removed In Release: v17.12
Version 1.8.3 added a flag (--disable-legacy-registry=false) which prevents the docker daemon from pull, push, and login operations against v1 registries. Though enabled by default, this signals the intent to deprecate the v1 protocol.
Support for the v1 protocol to the public registry was removed in 1.13. Any mirror configurations using v1 should be updated to use a v2 registry mirror.
Starting with Docker 17.12, support for V1 registries has been removed, and the --disable-legacy-registry flag can no longer be used, and dockerd will fail to start when set.
--disable-legacy-registry override daemon optionDisabled In Release: v17.12
Target For Removal In Release: v18.03
The --disable-legacy-registry flag was disabled in Docker 17.12 and will print an error when used. For this error to be printed, the flag itself is still present, but hidden. The flag will be removed in Docker 18.03.
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
--api-enable-cors flag on dockerdDeprecated In Release: v1.6.0
Removed In Release: v17.09
The flag --api-enable-cors is deprecated since v1.6.0. Use the flag --api-cors-header instead.
