| <B>SYNOPSIS</B> |
| gsutil [-D] config [-a] [-b] [-f] [-o <file>] [-r] [-s <scope>] [-w] |
| |
| |
| <B>DESCRIPTION</B> |
| The gsutil config command obtains access credentials for Google Cloud |
| Storage and writes a boto/gsutil configuration file containing the obtained |
| credentials along with a number of other configuration-controllable values. |
| |
| Unless specified otherwise (see OPTIONS), the configuration file is written |
| to ~/.boto (i.e., the file .boto under the user's home directory). If the |
| default file already exists, an attempt is made to rename the existing file |
| to ~/.boto.bak; if that attempt fails the command will exit. A different |
| destination file can be specified with the -o option (see OPTIONS). |
| |
| Because the boto configuration file contains your credentials you should |
| keep its file permissions set so no one but you has read access. (The file |
| is created read-only when you run gsutil config.) |
| |
| |
| <B>CREDENTIALS</B> |
| By default gsutil config obtains OAuth2 credentials, and writes them |
| to the [Credentials] section of the configuration file. The -r, -w, |
| -f options (see OPTIONS below) cause gsutil config to request a token |
| with restricted scope; the resulting token will be restricted to read-only |
| operations, read-write operation, or all operations (including getacl/setacl/ |
| getdefacl/setdefacl/disablelogging/enablelogging/getlogging operations). In |
| addition, -s <scope> can be used to request additional (non-Google-Storage) |
| scopes. |
| |
| If you want to use credentials based on access key and secret (the older |
| authentication method before OAuth2 was supported) instead of OAuth2, |
| see help about the -a option in the OPTIONS section. |
| |
| If you wish to use gsutil with other providers (or to copy data back and |
| forth between multiple providers) you can edit their credentials into the |
| [Credentials] section after creating the initial configuration file. |
| |
| |
| <B>CONFIGURATION FILE SELECTION PROCEDURE</B> |
| By default, gsutil will look for the configuration file in /etc/boto.cfg and |
| ~/.boto. You can override this choice by setting the BOTO_CONFIG environment |
| variable. This is also useful if you have several different identities or |
| cloud storage environments: By setting up the credentials and any additional |
| configuration in separate files for each, you can switch environments by |
| changing environment variables. |
| |
| You can also set up a path of configuration files, by setting the BOTO_PATH |
| environment variable to contain a ":" delimited path. For example setting |
| the BOTO_PATH environment variable to: |
| |
| /etc/projects/my_group_project.boto.cfg:/home/mylogin/.boto |
| |
| will cause gsutil to load each configuration file found in the path in |
| order. This is useful if you want to set up some shared configuration |
| state among many users: The shared state can go in the central shared file |
| ( /etc/projects/my_group_project.boto.cfg) and each user's individual |
| credentials can be placed in the configuration file in each of their home |
| directories. (For security reasons users should never share credentials |
| via a shared configuration file.) |
| |
| |
| <B>CONFIGURATION FILE STRUCTURE</B> |
| The configuration file contains a number of sections: [Credentials], |
| [Boto], [GSUtil], and [OAuth2]. If you edit the file make sure to edit the |
| appropriate section (discussed below), and to be careful not to mis-edit |
| any of the setting names (like "gs_access_key_id") and not to remove the |
| section delimiters (like "[Credentials]"). |
| |
| |
| <B>ADDITIONAL CONFIGURATION-CONTROLLABLE FEATURES</B> |
| With the exception of setting up gsutil to work through a proxy (see |
| below), most users won't need to edit values in the boto configuration file; |
| values found in there tend to be of more specialized use than command line |
| option-controllable features. |
| |
| The following are the currently defined configuration settings, broken |
| down by section. Their use is documented in comments preceding each, in |
| the configuration file. If you see a setting you want to change that's not |
| listed in your current file, see the section below on Updating to the Latest |
| Configuration File. |
| |
| The currently supported settings, are, by section: |
| [Boto] |
| proxy |
| proxy_port |
| proxy_user |
| proxy_pass |
| is_secure |
| https_validate_certificates |
| send_crlf_after_proxy_auth_headers |
| debug |
| num_retries |
| |
| [GSUtil] |
| resumable_threshold |
| resumable_tracker_dir |
| parallel_process_count |
| parallel_thread_count |
| default_api_version |
| default_project_id |
| use_magicfile |
| |
| [OAuth2] |
| token_cache |
| token_cache |
| client_id |
| client_secret |
| provider_label |
| provider_authorization_uri |
| provider_token_uri |
| |
| |
| <B>UPDATING TO THE LATEST CONFIGURATION FILE</B> |
| We add new configuration controllable features to the boto configuration file |
| over time, but most gsutil users create a configuration file once and then |
| keep it for a long time, so new features aren't apparent when you update |
| to a newer version of gsutil. If you want to get the latest configuration |
| file (which includes all the latest settings and documentation about each) |
| you can rename your current file (e.g., to '.boto_old'), run gsutil config, |
| and then edit any configuration settings you wanted from your old file |
| into the newly created file. Note, however, that if you're using OAuth2 |
| credentials and you go back through the OAuth2 configuration dialog it will |
| invalidate your previous OAuth2 credentials. |
| |
| If no explicit scope option is given, -f (full control) is assumed by default. |
| |
| |
| <B>OPTIONS</B> |
| -a Prompt for Google Cloud Storage access key and secret (the older |
| authentication method before OAuth2 was supported) instead of |
| obtaining an OAuth2 token. |
| |
| -b Causes gsutil config to launch a browser to obtain OAuth2 approval |
| and the project ID instead of showing the URL for each and asking |
| the user to open the browser. This will probably not work as |
| expected if you are running gsutil from an ssh window, or using |
| gsutil on Windows. |
| |
| -f Request token with full-control access (default). |
| |
| -o <file> Write the configuration to <file> instead of ~/.boto. |
| Use '-' for stdout. |
| |
| -r Request token restricted to read-only access. |
| |
| -s <scope> Request additional OAuth2 <scope>. |
| |
| -w Request token restricted to read-write access. |
