Highlights:
- bug fixes, in particular eradicating several deadlocks that could cause peer connection failures and hangs.
- performance and scalability improvements to the weave control plane, as a result of which it is now possible to construct much larger weave networks than previously.
- improved installation and administration, particularly the introduction of remote execution of the weave script in a container, permitting fully containerised deployment of weave.
- improved diagnostics, such as the reporting of connection failures
in
weave status
. - new weaveDNS features, most notably the caching of DNS records for application containers, which makes finding container IP addresses via weaveDNS much faster.
More detail in the change log
NB: This release changes the Weave Docker image names. To upgrade
from an older version, 1) stop all application containers, 2) run
weave reset
from the old version to remove all traces of weave, and
only then 3) install the new version.
-
Improve WeaveDNS to the point where it can act as the name server for containers in nearly all situations.
-
Diagnose and report peer connectivity more comprehensively.
-
Adapt to changes in topology - adding & removing of weave peers, disruption of connectivity - more rapidly.
-
Cope with delays in downloading/running docker images/containers required for weave operation.
See the complete change log for more details.
-
Align script and image version. When the
weave
script has a version number, i.e. it is part of an official release, it runs docker images matching that version. Thus the script and image versions are automatically aligned. Unversioned/unreleasedweave
scripts run the 'latest'-tagged image versions. -
Eliminate dependency on ethtool and conntrack. Instead of requiring these to be installed on the host, weave invokes them via a
weavetools
docker image that contains minimally packaged versions of these utilities. -
New
weave setup
command. This downloads all docker images used by weave. Invoking this is strictly optional; its main purpose is to facilitate automated installation of weave and preventing delays in subsequent weave command execution due to image downloading.
This is the first release assigned a version number.
When downloading weave you now have the following choices...
- a specific version, e.g. https://github.com/weaveworks/weave/releases/download/v0.7.0/weave
- latest released version: https://github.com/weaveworks/weave/releases/download/latest_release/weave
- most recent 'master' commit: https://raw.githubusercontent.com/weaveworks/weave/master/weave
Previously the only documented download location was (3). We recommend that any automated scripts using that be changed to either (1) or (2).
