DESCRIPTION

       Given a local dataset, and SSH login information this command creates a  remote  dataset  repository  and
       configures it as a dataset sibling to be used as a publication target (see PUBLISH command).

       Various  properties  of  the remote sibling can be configured (e.g. name location on the server, read and
       write access URLs, and access permissions.

       Optionally, a basic web-viewer for DataLad datasets can be installed at the remote location.

       This command supports recursive processing of dataset hierarchies, creating a  remote  sibling  for  each
       dataset in the hierarchy. By default, remote siblings are created in hierarchical structure that reflects
       the  organization on the local file system. However, a simple templating mechanism is provided to produce
       a flat list of datasets (see --target-dir).

OPTIONS

SSHURL Login information for the target server. This can be given as a URL (ssh://host/path) or SSH-style
(user@host:path). Unless overridden, this also serves the future dataset's access URL and path on
the server. Constraints: value must be a string

-h, -\-help, -\-help-np
show this help message. --help-np forcefully disables the use of a pager for displaying the help
message

-s [NAME], -\-name [NAME]
sibling name to create for this publication target. If RECURSIVE is set, the same name will be
used to label all the subdatasets' siblings. When creating a target dataset fails, no sibling is
added. Constraints: value must be a string

-\-target-dir PATH
path to the directory *on the server* where the dataset shall be created. By default the SSH ac‐
cess URL is used to identify this directory. If a relative path is provided here, it is interpret‐
ed as being relative to the user's home directory on the server. Additional features are relevant
for recursive processing of datasets with subdatasets. By default, the local dataset structure is
replicated on the server. However, it is possible to provide a template for generating different
target directory names for all (sub)datasets. Templates can contain certain placeholder that are
substituted for each (sub)dataset. For example: "/mydirectory/dataset%RELNAME". Supported place‐
holders: %RELNAME - the name of the datasets, with any slashes replaced by dashes. Constraints:
value must be a string

-\-target-url URL
"public" access URL of the to-be-created target dataset(s) (default: SSHURL). Accessibility of
this URL determines the access permissions of potential consumers of the dataset. As with TAR‐
GET_DIR, templates (same set of placeholders) are supported. Also, if specified, it is provided as
the annex description. Constraints: value must be a string

-\-target-pushurl URL
In case the TARGET_URL cannot be used to publish to the dataset, this option specifies an alterna‐
tive URL for this purpose. As with TARGET_URL, templates (same set of placeholders) are supported.
Constraints: value must be a string

-\-dataset DATASET, -d DATASET
specify the dataset to create the publication target for. If no dataset is given, an attempt is
made to identify the dataset based on the current working directory. Constraints: Value must be a
Dataset or a valid identifier of a Dataset (e.g. a path)

-r, -\-recursive
if set, recurse into potential subdataset.

-R LEVELS, -\-recursion-limit LEVELS
limit recursion into subdataset to the given number of levels. Constraints: value must be convert‐
ible to type 'int'

-\-existing MODE
action to perform, if a sibling is already configured under the given name and/or a target direc‐
tory already exists. In this case, a dataset can be skipped ('skip'), an existing target directory
be forcefully re-initialized, and the sibling (re-)configured ('replace', implies 'reconfigure'),
the sibling configuration be updated only ('reconfigure'), or to error ('error'). Constraints:
value must be one of ('skip', 'replace', 'error', 'reconfigure') [Default: 'error']

-\-shared {false|true|umask|group|all|world|everybody|0xxx}
if given, configures the access permissions on the server for multi-users (this could include ac‐
cess by a webserver!). Possible values for this option are identical to those of `git init
--shared` and are described in its documentation. Constraints: value must be a string, or value
must be convertible to type bool

-\-group GROUP
Filesystem group for the repository. Specifying the group is particularly important when
--shared=group. Constraints: value must be a string

-\-ui {false|true|html_filename}
publish a web interface for the dataset with an optional user-specified name for the html at pub‐
lication target. defaults to INDEX.HTML at dataset root. Constraints: value must be convertible to
type bool, or value must be a string [Default: False]

-\-as-common-datasrc NAME
configure the created sibling as a common data source of the dataset that can be automatically
used by all consumers of the dataset (technical: git-annex auto-enabled special remote).

-\-publish-by-default REFSPEC
add a refspec to be published to this sibling by default if nothing specified. Constraints: value
must be a string

-\-publish-depends SIBLINGNAME
add a dependency such that the given existing sibling is always published prior to the new sib‐
ling. This equals setting a configuration item 'remote.SIBLINGNAME.datalad-publish-depends'. This
option can be given more than once to configure multiple dependencies. Constraints: value must be
a string

-\-annex-wanted EXPR
expression to specify 'wanted' content for the repository/sibling. See https://git-annex.branch‐
able.com/git-annex-wanted/ for more information. Constraints: value must be a string

-\-annex-group EXPR
expression to specify a group for the repository. See https://git-annex.branchable.com/git-annex-
group/ for more information. Constraints: value must be a string

-\-annex-groupwanted EXPR
expression for the groupwanted. Makes sense only if --annex-wanted="groupwanted" and annex-group
is given too. See https://git-annex.branchable.com/git-annex-groupwanted/ for more information.
Constraints: value must be a string

-\-inherit
if sibling is missing, inherit settings (git config, git annex wanted/group/groupwanted) from its
super-dataset.

-\-since SINCE
limit processing to datasets that have been changed since a given state (by tag, branch, commit,
etc). This can be used to create siblings for recently added subdatasets. Constraints: value must
be a string
