can't reload new configuration from disk on v0.18.0 #866

Closed hinsqueg closed 7 years ago

hinsqueg commented 7 years ago

When send the reload signal to v0.18.0 consul-template process, it does not load configuraion from the current disk files. It always uses the configurations which are loaded on startup.

Example 1:

  1. specify the _loglevel to info in the config file: /tmp/test.hcl 
    log_level = "info"
  2. run consul-template: 
    $ consul-template -config=/tmp/test.hcl -pid-file=/tmp/test.pid
  3. modify the '/tmp/test.hcl' content: set _loglevel to debug 
    log_level = "debug"
  4. send reload signal to consul-template process, expect to see some 'debug' log output, but nothing changed.

Example 2:

  1. make an empty directory 
    $ mkdir /tmp/testconfs
  2. run consul-template: 
    $ consul-template -config=/tmp/testconfs -pid-file=/tmp/test.pid
  3. create an file: '/tmp/testconfs/log.hcl', content is below: 
    log_level = "debug"
  4. send reload signal to consul-template process, expect to see some 'debug' log output, but nothing changed.

Confirming this issue. I noticed this when I added a configuration file to the directory passed into -config and the new configuration file didn't get picked up by reload. Also confirmed by putting consul-template in debug log_level then tried change it to info.

Here is the debug log:
