envconsul v0.3.0

[Seth Vargo]

Hello Consulers (again),

I am excited to announce the all new and shiny envconsul. We learned a lot from building Consul Template and wanted to apply the principles to the already-popular envconsul. Here's what we did:

FEATURES:

  * Watch and reload by default - previously you needed to specify the `-reload`

  flag for envconsul to poll, but this is now the default behavior - you can

  restore the old behavior using the new `-once` flag

  * Leverage watching libraries from Consul Template

  * Unified command interface with Consul Template

  * Added support for quiescene using the new `-wait` option

  * Added support for Consul ACLs using the new `-token` option

  * Added support for reading configuration from file using the new `-config`

  option - the config file is HCL

IMPROVEMENTS:

  * Added `-timeout` parameter for specifying the interval to wait for SIGTERM

  to return before sending SIGKILL

  * Added `-version` flag to print the current version of envconsul

  * Added a full debug log tracer which can be set using `ENV_CONSUL_LOG=debug`

  * Drastically improved documentation with usage examples and feature

  documentation

  * Add significantly more test coverage (still not 100%, but more more

  thoroughly tested)

DEPRECATIONS:

  * `-addr` is deprecated in favor of `-consul` and will be removed in the next

  major release

  * `-dc` is deprecated in favor of using the inline `@dc` syntax and will be

  removed in the next major release

  * `-errExit`, `-terminate`, and `-reload` are all deprecated in favor of

  `-once`. envconsul now intelligently exits where appropriate

You can download the latest release from the GitHub releases page:

As always, we aim to be 100% backwards compatible with previous releases. If you find a bug or regression, that was certainly not our intention and we are deeply sorry. As this was a fairly large refactor, please test in an isolated environment before upgrading. Please report bugs, issues features, and pull requests to envconsul on Github: https://github.com/hashicorp/envconsul.

Happy computing,

Seth
