confd

Features:

• add ls and lsdir template functions

This release adds the following features:

• JSON template functions - json, and jsonArray
• New flag: -keep-stage-file, to keep the stage files around after confd exits and log the full path to the staged file.

This is a backwards incompatible release. Confd has seen a lot of changes over the last year and it's time to clean thing up a bit. Most users will have to update their Go templates to use the new template functions, others may have to adjust configuration files and command line args.

Since there are a lot of changes in this release 0.5.x will be around for a few more months. This clean up is an effort to get to 1.0 and add watch support for consul and etcd. Please kick the tires and offer feedback.

All work for the 0.6.0 release is being done on the 0.6.x branch.

Release Notes:

• All the old template functions have been removed in this release and are being replaced. See the new templates doc
• etcd specific command line flags have be removed. All flags now work with all backends.
• Keys can only be accessed via template functions (get, gets, getv, and getvs) No more {{.key_subkey}}. See the new templates doc
• Template functions stop execution if keys are not found. Before the default value of a string was returned
• Updated docs
• Confd uses an internal key/value store. See memkv
• Support SRV DNS records for consul
• Switch to the new consul-api Go library
• Keys must use the "/" prefix inside templates and TOML configs

Features:

• Handle common shutdown signals and exit cleanly
• Smaller confd binary
• log reload_cmd and check_cmd output when running in debug mode
• Support for multiple scoped resources using the same template. Templates get their own optional prefixes.

Bug fixes:

• Update upstream consul client library - fixes to many open files issue because of unclosed HTTP request bodies
• Update etcd client library
