Flux 1.13.0

This feature release contains an experimental feature for generating manifests from the sources in git and completes the support for GPG signatures.

Fixes

• Use openssh-client rather than openssh in container image weaveworks/flux#2142
• Cope when filenames from git start or end with spaces weaveworks/flux#2117
• Ignore metrics API group, known to be problematic weaveworks/flux#2096
• Remove a possible deadlock from code calling git weaveworks/flux#2086

Enhancements

• When --manifest-generation is set, look for .flux.yaml files in the git repo and generate manifests according to the instructions therein (see the docs) weaveworks/flux#1848
• Verify GPG signatures on commits (when --git-verify-signatures is set; see the docs) weaveworks/flux#1791
• Make the log format configurable (specifically to admit JSON logging) weaveworks/flux#2138
• Log when a requested workload is not of a kind known to fluxd weaveworks/flux#2097
• Get image build time from OCI labels, if present weaveworks/flux#1992, weaveworks/flux#2084
• A new flag --garbage-collection-dry-run will report what would be deleted by garbage collection in the log, without deleting it weaveworks/flux#2063

Maintenance and documentation

• Let fluxd be run outside a cluster, for development convenience weaveworks/flux#2140
• Documentation edits weaveworks/flux#2134, weaveworks/flux#2109
• Improve some tests weaveworks/flux#2111, weaveworks/flux#2110, weaveworks/flux#2085, weaveworks/flux#2090
• Give the memcached pod a security context weaveworks/flux#2125
• Move to go modules and abandon go dep weaveworks/flux#2083, weaveworks/flux#2127, weaveworks/flux#2094
• Give an example of DNS settings in the example deployment weaveworks/flux#2116
• Document how to get the fluxctl snap weaveworks/flux#1966, weaveworks/flux#2108
