[arvados] Arvados 2.2.0 released

[peter.amstutz at curii.com]

Hello ,

The Arvados team is pleased to announce Arvados 2.2.0. This release
includes a number of bug fixes as well as some new Workbench 2 features. We
recommend that new and existing installations of 2.1.2
<https://www-dev.arvados.org/release-notes/2.1.2> or earlier upgrade to
2.2.0. See Upgrading Arvados
<https://doc.arvados.org/v2.2/admin/upgrading.html> for upgrade
instructions.
Major Features Virtual Projects

Arvados now features virtual projects
<https://doc.arvados.org/main/api/projects.html>. These are projects who’s
contents are defined by an Arvados query. This enables cross-cutting views
that allow you to browse Arvados objects based on alternate criteria than
the normal project hierarchy. Virtual projects can also be used to group
other projects together to be shared among users with different levels of
access, each user only sees the subset of projects in the group that their
account is authorized to see.
SSH into Running Container

To help debug compute jobs, Arvados can now create a SSH tunnel to a
running Arvados container
<https://doc.arvados.org/main/user/debugging/container-shell-access.html>.
This enables you to open a shell session inside a running container, as
well as connect to open ports on the container.
Automatic logout and token expiration

To improve token handling security, there are now various options for automatic
logout and token expiration
<https://doc.arvados.org/main/admin/token-expiration-policy.html>.
Workbench plugins

You can now create plugins to add new custom functionality to Workbench 2
<https://github.com/arvados/arvados-workbench2/tree/master/src/plugins> and
build on the Workbench framework to rapidly develop custom applications on
top of Arvados.
Accept OpenID Access Tokens

When configured to use an OpenID Connect identity provider (such as Google,
PingFederate, or other systems supporting OIDC), Arvados will accept access
tokens issued by that provider in addition to the API tokens issued by
Arvados itself. This enables Single Sign On (SSO) integration with other
systems.
Cost Reporting

Arvados features two new tools to help collect information about usage and
cost.

The cost analyzer <https://doc.arvados.org/main/user/cwl/costanalyzer.html>
produces a report about the cost of compute node time used to run one or
more workflows.

The deduplication report
<https://doc.arvados.org/main/admin/keep-measuring-deduplication.html>
prints a report that shows the nominal space used by the collections, as
well as the actual size and the amount of space that is saved by Keep’s
deduplication.
Guide to using Visual Studio Code with Arvados

The user guide now features a section on Developing CWL Workflows with
VSCode <https://doc.arvados.org/main/user/cwl/arvados-vscode-training.html>.
User activity report

There is a new arv-user-activity
<https://doc.arvados.org/main/admin/user-activity.html> tool which
generates a summary report of user activity on an Arvados instance over
some time span based on the audit logs.
Other changes Improved installer

The Saltstack-based installation features improved single-node
<https://doc.arvados.org/main/install/salt-single-host.html> and multi-node
<https://doc.arvados.org/main/install/salt-multi-host.html> install options.
Improved configuration validation

Now gives improved warnings or errors for invalid configuration options.
Added support for Ubuntu 20.04 (“focal”)

For Arvados 2.2, the supported Linux distributions are Centos 7, Ubuntu
18.04, Ubuntu 20.04, and Debian 10.
Dropped support for Debian 9 (“stretch”) and Ubuntu 16.04 (“xenial”)

Debian 9 and Ubuntu 16.04 are no longer supported.
The “devise-omniauth” SSO server is no longer supported

Authentication methods have moved into the Arvados Controller component.
Both Workbench 1 and Workbench 2 support direct username/password login
(for LDAP) as well third party identity providers. Arvados installations
using the “devise-omniauth” SSO server should migrate to one of the
built-in authentication methods as soon as possible. See setting up web
based login <https://doc.arvados.org/v2.2/install/setup-login.html> for
details.
Fixed bug 17566 <https://dev.arvados.org/issues/17566>: request body size
was incorrectly limited to 10M

Fixed bug where the request body size was incorrectly limited to 10M when
content-type is x-www-form-urlencoded.
Fixed bug 17566 <https://dev.arvados.org/issues/17566>: keep-web tolerates
superfluous :443 in config.yml

Fixed bug in which keep-web, when configured with explict port numbers,
would fail to recognize virtual hosts that did not have explicit port
numbers, even when using standard ports :80 or :443.

Thanks,

The Arvados team
