A data bag is indexed for searching and can be loaded by a recipe or accessed during a search. The contents of a data bag can vary, but they often include sensitive information (such as database passwords). .sp A data bag item may be encrypted using \fI\%shared secret encryption\fP. This allows each data bag item to store confidential information (such as a database password) or to be managed in a source control system (without plain\-text data appearing in revision history). Each data bag item may be encrypted individually; if a data bag contains multiple encrypted data bag items, these data bag items are not required to share the same encryption keys. .sp The \fBknife data bag\fP subcommand is used to manage arbitrary stores of globally available JSON data. .SH COMMON OPTIONS .sp The following options may be used with any of the arguments available to the \fBknife data bag\fP subcommand: .INDENT 0.0 .TP .B \fB\-\-chef\-zero\-port PORT\fP The port on which chef\-zero will listen. .TP .B \fB\-c CONFIG_FILE\fP, \fB\-\-config CONFIG_FILE\fP The configuration file to use. .TP .B \fB\-d\fP, \fB\-\-disable\-editing\fP Indicates that $EDITOR will not be opened; data will be accepted as\-is. .TP .B \fB\-\-defaults\fP Indicates that Knife will use the default value, instead of asking a user to provide one. .TP .B \fB\-e EDITOR\fP, \fB\-\-editor EDITOR\fP The $EDITOR that is used for all interactive commands. .TP .B \fB\-E ENVIRONMENT\fP, \fB\-\-environment ENVIRONMENT\fP The name of the environment. When this option is added to a command, the command will run only against the named environment. .TP .B \fB\-F FORMAT\fP, \fB\-\-format FORMAT\fP The output format: \fBsummary\fP (default), \fBtext\fP, \fBjson\fP, \fByaml\fP, and \fBpp\fP. .TP .B \fB\-h\fP, \fB\-\-help\fP Shows help for the command. .TP .B \fB\-k KEY\fP, \fB\-\-key KEY\fP The private key that Knife will use to sign requests made by the API client to the server. .TP .B \fB\-\-[no\-]color\fP Indicates whether colored output will be used. .TP .B \fB\-\-print\-after\fP Indicates that data will be shown after a destructive operation. .TP .B \fB\-s URL\fP, \fB\-\-server\-url URL\fP The URL for the server. .TP .B \fB\-u USER\fP, \fB\-\-user USER\fP The user name used by Knife to sign requests made by the API client to the server. Authentication will fail if the user name does not match the private key. .TP .B \fB\-V\fP, \fB\-\-verbose\fP Set for more verbose outputs. Use \fB\-VV\fP for maximum verbosity. .TP .B \fB\-v\fP, \fB\-\-version\fP The version of the chef\-client. .TP .B \fB\-y\fP, \fB\-\-yes\fP Indicates that the response to all confirmation prompts will be "Yes" (and that Knife will not ask for confirmation). .TP .B \fB\-z\fP, \fB\-\-local\-mode\fP Indicates that the chef\-client will be run in local mode, which allows all commands that work against the server to also work against the local chef\-repo. .UNINDENT .SH CREATE .sp The \fBcreate\fP argument is used to add a data bag to the server. .sp \fBSyntax\fP .sp This argument has the following syntax: .sp .nf .ft C $ knife data bag create DATA_BAG_NAME [DATA_BAG_ITEM] (options) .ft P .fi .sp \fBOptions\fP .sp This argument has the following options: .INDENT 0.0 .TP .B \fBDATA_BAG_ITEM\fP The name of a specific item within a data bag. .TP .B \fB\-\-secret SECRET\fP The encryption key that is used for values contained within a data bag item. .TP .B \fB\-\-secret\-file FILE\fP The path to the file that contains the encryption key. .UNINDENT .IP Note For encrypted data bag items, use \fIeither\fP \fB\-\-secret\fP or \fB\-\-secret\-file\fP, not both. .RE .sp \fBExamples\fP .sp To create a data bag named "admins", enter: .sp .nf .ft C $ knife data bag create admins .ft P .fi .sp to return: .sp .nf .ft C Created data_bag[admins] .ft P .fi .SH DELETE .sp The \fBdelete\fP argument is used to delete a data bag or a data bag item from a server. .sp \fBSyntax\fP .sp This argument has the following syntax: .sp .nf .ft C $ knife data bag delete DATA_BAG_NAME [DATA_BAG_ITEM] (options) .ft P .fi .sp \fBOptions\fP .sp This argument has the following options: .INDENT 0.0 .TP .B \fBDATA_BAG_ITEM\fP The name of a specific item within a data bag. .UNINDENT .sp \fBExamples\fP .sp .nf .ft C $ knife data bag delete data_bag_name .ft P .fi .sp To delete an item named "charlie", enter: .sp .nf .ft C $ knife data bag delete admins charlie .ft P .fi .sp Type \fBY\fP to confirm a deletion. .SH EDIT .sp The \fBedit\fP argument is used to edit the data contained in a data bag. If encryption is being used, the data bag will be decrypted, the data will be made available in the $EDITOR, and then encrypted again before saving it to the server. .sp \fBSyntax\fP .sp This argument has the following syntax: .sp .nf .ft C $ knife data bag edit DATA_BAG_NAME [DATA_BAG_ITEM] (options) .ft P .fi .sp \fBOptions\fP .sp This argument has the following options: .INDENT 0.0 .TP .B \fBDATA_BAG_ITEM\fP The name of a specific item within a data bag. .TP .B \fB\-\-secret SECRET\fP The encryption key that is used for values contained within a data bag item. .TP .B \fB\-\-secret\-file FILE\fP The path to the file that contains the encryption key. .UNINDENT .IP Note For encrypted data bag items, use \fIeither\fP \fB\-\-secret\fP or \fB\-\-secret\-file\fP, not both. .RE .sp \fBExamples\fP .sp To edit the contents of a data bag, enter: .sp .nf .ft C $ knife data bag edit admins .ft P .fi .sp To edit an item named "charlie" that is contained in a data bag named "admins", enter: .sp .nf .ft C $ knife data bag edit admins charlie .ft P .fi .sp to open the $EDITOR. Once opened, you can update the data before saving it to the server. For example, by changing: .sp .nf .ft C { "id": "charlie" } .ft P .fi .sp to: .sp .nf .ft C { "id": "charlie", "uid": 1005, "gid":"ops", "shell":"/bin/zsh", "comment":"Crazy Charlie" } .ft P .fi .SH FROM FILE .sp The \fBfrom file\fP argument is used to create a data bag on the server from a file.
