Uploading data

If you need any help while uploading local data to a container, run ovhai bucket object upload --help:

Usage:
    ovhai bucket object upload [OPTIONS] <BUCKET> <PATHS>...

Arguments:
    <BUCKET>    container@data_store
    <PATHS>...  Name of file or directory to upload

Options:
    -a, --add-prefix <ADD_PREFIX>        Add prefix to uploaded objects
        --token <TOKEN>                  Authentication using Token rather than OAuth
    -r, --remove-prefix <REMOVE_PREFIX>  Remove prefix from uploaded objects
      --no-overwrite                     Do not overwrite objects
    -j, --json                           Output json progress
    -w, --workers <WORKERS>              Number of workers to use
      --delete                           Should also delete files in remote storage that are not present locally. !!WARNING!! we strongly advise to use `--dry-run` once before launching this command for real, also see the `--trash` option
      --trash <TRASH>                    Move files to this container and folder instead of deleting them, to be used with `--delete` (eg. `--trash trash_container/job1/`)
      --dry-run                          Doesn't execute anything but display what actions would be done if this flag was not set
      --tar <TAR>                        Compress all paths inside a tar archive before uploading it
      --no-color                         Remove colors from output
    -h, --help                           Print help

A good practice is to use the --dry-run parameter to get a preview of the actions that would be done by the entered command if this flag was not set.

Uploading data - Example 1

Use this command to upload the local file (or directory) /tmp/directory/file1 into the container my-container in region GRA while keeping the full path as object name:

ovhai bucket object upload my-container@GRA tmp/directory/file1

The uploaded file (or directory) will have tmp/directory/file1 as object name.

Uploading data - Example 2

Use this command to upload the local file (or directory) /tmp/directory/file1 into the container my-container in region GRA while keeping only the file name as object name:

ovhai bucket object upload my-container@GRA tmp/directory/file1 --remove-prefix tmp/directory/

The uploaded file (or directory) will have file1 as object name.

Uploading data - Example 3

Use this command to upload the local file (or directory) /tmp/directory/file1 into the container my-container in region GRA while adding a prefix to the full path as object name:

ovhai bucket object upload my-container@GRA tmp/directory/file1 --add-prefix /root/

The uploaded file (or directory) will have /root/tmp/directory/file1 as object name.

Downloading data

If you need any help for downloading objects from a container, run ovhai bucket object download --help:

Usage:
    ovhai bucket object download [OPTIONS] <BUCKET> [OBJECTS]...

Arguments:
    <BUCKET>      container@data_store
    [OBJECTS]...  Names of objects to download

    -r, --remove-prefix <REMOVE_PREFIX>  Remove prefix from downloaded items
        --no-overwrite                   Do not overwrite files
        --create                         Create container if it does not exist
    -j, --json                           Output json progress
    -w, --workers <WORKERS>              Number of workers to use for downloading objects
        --delete                         Should also delete files locally if they are not present on remote. !!WARNING!! we strongly advise to use `--dry-run` once before launching this command for real, also see the `--trash` option
        --trash <TRASH>                  Move files to this folder instead of deleting them, to be used with `--delete`
        --dry-run                        Doesn't execute anything but display what actions would be done if this flag was not set
        --untar                          Uncompress given archive from object store
        --no-color                       Remove colors from output
    -h, --help                           Print help

A good practice is to use the --dry-run parameter to get a preview of the actions that would be done by the entered command if this flag was not set.

Downloading data - Example 1

Use this command to download the whole container my-container in region GRA:

ovhai bucket object download my-container@GRA

If the objects are prefixed with a directory path such as /tmp/directory/ or even /, then it will be downloaded on your local storage inside that same directory. If you want to download everything inside your current directory you need to fill the --remove-prefix parameter.

Example:

ovhai bucket object download my-container@GRA --remove-prefix tmp/directory/

Downloading data - Example 2

Use this command to download all the objects from my-container in region GRA matching the prefix tmp/directory/:

ovhai bucket object download my-container@GRA --prefix tmp/directory/

Same warning as above, if you want to download files on your current directory you will need to fill the --remove-prefix parameter.

Example:

ovhai bucket object download my-container@GRA --prefix tmp/directory/ --remove-prefix tmp/directory/

Deleting data

If you need any help for deleting container or objects, run ovhai bucket delete --help:

Usage:
    ovhai bucket delete [OPTIONS] <DELETED_ITEMS|--prefix <PREFIX>|--all> <DATA_STORE>

Arguments:
    <DATA_STORE>        Object storage data store alias
    [DELETED_ITEMS]...  List of items to be deleted

Options:
    -p, --prefix <PREFIX>    Items beginning with <PREFIX>
        --token <TOKEN>      Authentication using Token rather than OAuth
    -a, --all                All items
    -y, --yes                Do not ask for confirmation
    -w, --workers <WORKERS>  Number of workers to use
        --no-color           Remove colors from output
    -h, --help               Print help

Deleting data - Example 1

Use this command to delete all the content of a container named my-container, in region GRA, without deleting the container:

ovhai bucket object delete my-container@GRA --all

Deleting data - Example 2

Use this command to delete a single object named file1 inside the container my-container of region GRA:

ovhai bucket object delete my-container@GRA file1

Deleting data - Example 3

Once a container is empty, you can delete it by using: 

ovhai bucket delete GRA my-container

Copying data

When using containers, it can be interesting to copy an object. If you need any help to do this, run ovhai bucket object copy --help:

Usage:
    ovhai bucket object copy [OPTIONS] <DESTINATION|--container <CONTAINER>> <BUCKET> <SOURCE>

Arguments:
    <BUCKET>       container@data_store
    <SOURCE>       Source
    [DESTINATION]  Destination

Options:
    -c, --container <CONTAINER>  Destination container in the same data store
        --token <TOKEN>          Authentication using Token rather than OAuth
    -p, --prefix                 Handle element by matching prefix instead of name
    -y, --yes                    Do not ask for confirmation
    -w, --workers <WORKERS>      Number of workers to use
        --no-color               Remove colors from output
    -h, --help                   Print help

Copying data - Example 1

Use this command to copy a single object path/to/object in a container my-container in region GRA:

ovhai bucket object copy my-container@GRA path/to/object new/path/to/object

Copying data - Example 2

If you handle multiple containers, you might be interested in copying a file from one container to another. This can be done like this:

ovhai bucket object copy source-container@GRA --container dest-container path/to/object new/path/to/object

Copying data - Example 3

You can use a prefix to copy all objects contained in this location. For example, let's copy all the elements contained in the location path/to/ to a new/path/to/ of a dest-container:

ovhai bucket object copy source-container@GRA --container dest-container --prefix path/to/ new/path/to/

Moving data

You can also move an object within a container or in another one. If you need any help, run ovhai bucket object move --help:

Usage:
    ovhai bucket object move [OPTIONS] <DESTINATION|--container <CONTAINER>> <BUCKET> <SOURCE>

Arguments:
    <BUCKET>       container@data_store
    <SOURCE>       Source
    [DESTINATION]  Destination

Options:
    -c, --container <CONTAINER>  Destination container in the same data store
        --token <TOKEN>          Authentication using Token rather than OAuth
    -p, --prefix                 Handle element by matching prefix instead of name
    -y, --yes                    Do not ask for confirmation
    -w, --workers <WORKERS>      Number of workers to use
        --no-color               Remove colors from output
    -h, --help                   Print help

Moving data - Example 1

To move an object within a container, you can use:

ovhai bucket object move my-container@GRA path/to/object new/path/to/object

Moving data - Example 2

When handling multiple containers, it can be interesting to move a file from one container to another. This can be done by running:

ovhai bucket object copy source-container@GRA --container dest-container path/to/object new/path/to/object

Moving data - Example 3

If you want to move many objects, you can specify a prefix and move all the objects located here by using:

ovhai bucket object move my-container@GRA --prefix path/to/ new/path/to/
