Globus Connect Server Storage Gateway Create iRODS
Description
The globus-connect-server storage-gateway create command creates a new storage gateway. When creating a storage gateway, provide the policies to access a storage system via Globus Connect Server collections.
The iRODS connector provides access to data resources on the configured iRODS server.
Authentication Policies
There are three command-line options that control which user identities are allowed access to the data on a storage gateway: --domain, --authentication-timeout-mins, and --high-assurance.
The value of the --domain command-line option restricts access to users who have an identity in the given domain. This may be configured to be multiple values to allow authentication by multiple identity providers. If more than one domain is allowed, the storage gateway needs to have an identity mapping method configured to decide how to process names from the different identity namespaces. See Identity Mapping Policies for more information.
The value of the --authentication-timeout-mins command-line option defines the timeout (in minutes) after which a user will need to re-authenticate in order to access mapped collections on non high assurance storage gateways or for any data access on high assurance storage gateways. If this is not supplied, the default value of this timeout is 11 days.
The value of the --high-assurance command-line option defines whether the storage gateway manages high assurance data. If it is set, then the authentication timeout is enforced on per application sessions. This option can only be set when the storage gateway is created and is immutable.
Identity Mapping Policies
Globus Connect Server v5.4 supports a flexible system for mapping user identity information in Globus to the local account needed to access data on a variety of storage systems. This includes a default mapping for cases where there is only one allowed domain, as well as pattern-based mappings and callouts to external programs for custom mapping algorithms.
Default Identity to Username Mapping
When Globus Connect Server maps an identity to an account, it strips off the data after the @
character by default, so the username user@example.org
is mapped to the
account user
.
Custom Identity to Username Mapping
The --identity-mapping command-line option configures a storage gateway to use either an expression based identity mapping or an external identity mapping program. See the Identity Mapping Guide for more information.
The --identity-mapping command-line option can be passed on the command-line with a few different types of data as its arguments:
-
--identity-mapping external:
CMD
-
When mapping a identity to a username, Globus Connect Server invokes the command-line program
CMD
to map the identity. The value of theCMD
string will be parsed as a shell command-line, so arguments may be included if quoted. A full description of the input, output, and arguments to the program are included in Identity Mapping Guide. -
--identity-mapping file:
JSON_FILE
-
--identity-mapping
JSON
-
The
JSON_FILE
argument is a path to a file which contains a JSON document containing the mapping configuration, as described in the Identity Mapping Guide. TheJSON
argument is the json document itself.
User Policies
The --user-allow and --user-deny command-line options control which users may access data on a storage gateway. These operate on the result of the identity mapping, a user name that is in the namespace of storage gateway. This may be a user name, id, or email address based on the storage gateway requirements.
A username is allowed or denied access depending on whether the --user-allow and --user-deny command-line option are set on a storage gateway, and whether the username is present in one or both of those policies. In general, if a username is in the value of --user-deny it is always denied, and if a --user-allow policy is provided the username must be in the policy value in order to be allowed access.
The full set of effects of these policies are contained in the following table:
--user-allow | --user-deny | result |
---|---|---|

iRODS Policies
The iRODS connector acts as a client to an iRODS server. The configuration
parameters for this are set in an irods client environment file, usually named
~/.irods/irods_environment.json
. The path to this file on the endpoint is configured
using the --irods-environment-file command-line option.
The irods client environment file must name an admin user. The password token
for this user is stored in an authentication file, commonly named ~/.irods/.irodsA
.
The path to this file on the endpoint is configured using the
--irods-authentication-file command-line option.
Both of these files must be readable by the user gcsweb
on the endpoint. The
iinit command can be used to create them.
For more information, see the iRODS connector documentation or the iRODS configuration documentation.
Data Access Policies
The --restrict-paths command-line option controls access to subtrees of the data provided by the storage gateway. This is configured using the PathRestrictions document type.
Path restrictions provide a framework for administrators to constrain data access on the storage gateway. Restrictions can be set at the folder level. They may allow read, write, or deny access to data. These are absolute paths from the root of the storage gateway virtual file system.
Network Use Policies
The command line option --network-use alters the network performance and scalability parameters used by collections created using this storage gateway, overriding the default behavior set on the endpoint. This feature can only be used with a Globus subscription.
If the network use is set to custom
, then all of the
--preferred-parallelism, --max-parallelism, --preferred-concurrency, and
--max-concurrency options must also be set. See the
network use section
of the installation guide for a description of what these values mean.
If the network use is set to null
, then the default behavior is restored, and
collections use the settings on the endpoint.
