Consul Template 0.10.0

[Seth Vargo]

Hi Consulers,

I am excited to announce the release of Consul Template v0.10.0:

FEATURES

  * Add `plugin` and plugin ecosystem

  * Add `parseBool` function for parsing strings into booleans (GH-312)

  * Add `parseFloat` function for parsing strings into float64 (GH-312)

  * Add `parseInt` function for parsing strings into int64 (GH-312)

  * Add `parseUint` function for parsing strings into uint64 (GH-312)

  * Add `explode` function for exploding the result of `tree` or `ls` into a

    deeply nested  hash (GH-311)

  * Add `toJSON` and `toJSONPretty` function for exporting the result of `tree`

    or `ls`  into a JSON hash (GH-311)

  * Add `toYAML` function for exporting the result of `tree` or `ls` into a

    YAML document (GH-311)

  * Add `node` function for querying nodes (GH-306, GH-309)

  * Add `split` function for splitting a string on a separator (GH-285)

  * Add `join` function for joining a string slice on a given key (GH-285)

  * Add `pid_file` configuration and command line option for specifying the

    location of a pid file on disk (GH-281, GH-286)

IMPROVEMENTS:

  * Allow setting log_level via the configuration file (CLI still take

    precedence if specified)

  * Improve error reporting when loading multiple configs by including the path

    on the configuration file that had an error (GH-275)

  * Add a timeout around command execution to prevent hanging (GH-283)

  * Read Vault/Consul environment variables for the config (GH-307, GH-308)

BUG FIXES:

  * Properly merge "default" config values with user-supplied values (GH-271)

You can download the release here: https://github.com/hashicorp/consul-template/releases/tag/v0.10.0, and the full changeset may be viewed here: https://github.com/hashicorp/consul-template/compare/v0.9.0...v0.10.0.

As always, please test in an isolated environment before upgrading.

Best,

Seth

Hi Seth,

Are you also planning to create/ provide an rpm or only tar ball ? if the latter, are you aware of any projects which builds the consul-template rpm?

cheers,
Dani

Hi Dani,

Consul Template is a single static binary. I think providing an RPM or Deb is overkill for such a tiny task :).

I don't think anyone installs/builds it as a package, but I can't be sure.

Best,

Seth

I've built debs for it - but not rpms:

I wanted to have better control over how and where it installed that didn't involve using Chef to unzip and place. The unzip library we were using with Chef at the time was a pain and didn't quite work correctly.

I'd be happy to accept patches that built an RPM and host it at package cloud if somebody was interested.

I use FPM to build .debs. It can build rpms too.

Dani, try it out, it's really easy.

Here's the command line for deb:

fpm -v 0.6.0-1  --provides consul-template --description="consul-template" --url https://github.com/hashicorp/consul-template -n consul-template -t deb -s dir consul-template_0.6.0_linux_amd64/consul-template=/opt/bin/

Seth, packages are really useful.  Not so much as an installation method, but also as a distribution mechanism via Yum or Apt.

I agree: it's not that updating a single binary is particularly difficult, but good package management does a lot more than just manage files.  It gives you the ability to perform updates cleanly via well-written phase scripts; integrate into startup management systems (SysV init, systemd, etc.); and uninstall easily, even without leaving a trace behind.

I'm not discouting any of those points, but OS packages is not something we plan at this time for Consul Template. Maybe in the future :).

Best,

Seth
