Upgrading to master¶

What you need to know and do in order to upgrade your Arvados site to the latest master.

Basics¶

apt-get dist-upgrade

(TODO: best order to upgrade? other best practices?)

Notable changes¶

Some versions introduce changes that require special attention when upgrading: e.g., there is a new service to install, or there is a change to the default configuration that you might need to override in order to preserve the old behavior.

(Note to developers: Add new items at the top. Include a relevant commit hash (probably a merge), date, issue number/link, and considerations/instructions for those about to upgrade.)

2015-01-05: e1276d6e disables Workbench's "Getting Started" popup by default.

• If you want new users to continue seeing this popup, set enable_getting_started_popup: true in Workbench's application.yml configuration.

2015-12-03: 5590c9ac makes a Keep-backed writable scratch directory available in crunch jobs (see #7751)

• All compute nodes must be upgraded to arvados-fuse >= 0.1.2015112518060 because crunch-job uses some new arv-mount flags (--mount-tmp, --mount-by-pdh) introduced in merge 346a558
• Jobs will fail if the API server (in particular crunch-job from the arvados-cli gem) is upgraded without upgrading arvados-fuse on compute nodes.

2015-11-11: 1e2ace5 changes recommended config for keep-web (see #5824)

• proxy/dns/ssl config should be updated to route "https://download.uuid_prefix.arvadosapi.com/" requests to keep-web (alongside the existing "collections" routing)
• keep-web command line adds -attachment-only-host download.uuid_prefix.arvadosapi.com
• Workbench config adds keep_web_download_url
• More info on the (still beta/non-TOC-linked) keep-web doc page

2015-11-04: 1d1c6de removes stopped containers (see #7444)

• arvados-docker-cleaner removes all docker containers as soon as they exit, effectively making docker run default to --rm. If you run arvados-docker-cleaner on a host that does anything other than run crunch-jobs, and you still want to be able to use docker start, read the new doc page to learn how to turn this off before upgrading.

2015-11-04: 21006cf adds a keep-web service (see #5824)

• Nothing relies on it yet, but early adopters can install it now by following http://doc.arvados.org/install/install-keep-web.html (it is not yet linked in the TOC).
