h1. Upgrading to master
What you need to know and do in order to upgrade your Arvados site to the latest master.
h2. Basics
apt-get dist-upgrade
(TODO: best order to upgrade? other best practices?)
h2. 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.)
2016-04-25: commit:eebcb5e requires the crunchrunner package to be installed on compute nodes and shell nodes in order to run CWL workflows.
* On each Debian-based compute node and shell node, run: @sudo apt-get install crunchrunner@
* On each Red Hat-based compute node and shell node, run: @sudo yum install crunchrunner@
2016-04-21: commit:3c88abd changes the Keep permission signature algorithm.
* All software components that generate signatures must be upgraded together. These are: keepstore, API server, keep-block-check, and keep-rsync. For example, if keepstore < 0.1.20160421183420 but API server >= 0.1.20160421183420, clients will not be able to read or write data in Keep.
* Jobs and client operations that are in progress during the upgrade (including arv-put's "resume cache") will fail.
2016-04-18: commit:a7d819f6 requires the crunchrunner package to be installed on compute nodes and shell nodes in order to run CWL workflows.
* On each Debian-based compute node and shell node, run: @sudo apt-get install crunchrunner@
* On each Red Hat-based compute node and shell node, run: @sudo yum install crunchrunner@
2015-01-05: commit: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: commit: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 commit: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: commit: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":http://doc.arvados.org/install/install-keep-web.html
2015-11-04: commit: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":http://doc.arvados.org/install/install-compute-node.html to learn how to turn this off before upgrading.
2015-11-04: commit: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).
