The following list of features are deprecated in Engine. To learn more about Docker Engine's deprecation policy, see Feature Deprecation Policy.
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: 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 loginDeprecated 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.
:) of --security-opt flag on docker runDeprecated 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 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).
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.
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.
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}}"
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
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.
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
