Issue #3910 has been updated by Oliver Hookins.
That almost entirely describes the current behaviour of our ENC. It looks at the environment that is being requested, and if it doesn't match what we expect to be assigning it, we send back a minimal catalog which just updates the puppet.conf with the correct environment and schedules another Puppet run to occur a couple of minutes later. It's not pretty, but it works. If a similar process could be orchestrated within the one runtime of the agent it would be ideal as opposed to waiting for the timer loop to trigger again, or a second cron/at-run process to start. ---------------------------------------- Bug #3910: Server is not authoritative over client environment when specified in an ENC https://projects.puppetlabs.com/issues/3910#change-56703 Author: Nigel Kersten Status: Merged - Pending Release Priority: Urgent Assignee: Patrick Carlisle Category: plumbing Target version: Telly Affected Puppet version: 0.25.4 Keywords: Branch: https://github.com/puppetlabs/puppet/pull/569 See: http://groups.google.com/group/puppet-dev/browse_thread/thread/b609965e377392ec To summarize, when the client specifies one environment and the classifier specifies another, classes are evaluated from the server-specified environment, and yet files are retrieved from the client-specified environment. 3 environments defined, each with a single class "base". */etc/puppet/puppet.conf* <pre> <...snip...> [one] modulepath = /etc/puppet/environments/one/modules [two] modulepath = /etc/puppet/environments/two/modules [three] modulepath = /etc/puppet/environments/three/modules </pre> */etc/puppet/environments/one/modules/base/manifests/init.pp* <pre> class base { notify { "hardwired one": } notify { "variable $environment": } file { "/tmp/environment_test": source => "puppet:///base/tester", } } </pre> */etc/puppet/environments/two/modules/base/manifests/init.pp* <pre> class base { notify { "hardwired two": } notify { "variable $environment": } file { "/tmp/environment_test": source => "puppet:///base/tester", } } </pre> */etc/puppet/environments/three/modules/base/manifests/init.pp* <pre> class base { notify { "hardwired three": } notify { "variable $environment": } file { "/tmp/environment_test": source => "puppet:///base/tester", } } </pre> <pre> $ cat /etc/puppet/environments/{one,two,three}/modules/base/files/tester one two three </pre> Right? So we have two notify resources and a file resource. - The "hardwired" notify is to illustrate which class is being loaded. - The "variable" notify is to illustrate what $environment evaluates to in the manifests. - The file source is to illustrate which file is being sourced. I also have an external node classifier that always returns this: <pre> --- classes: - base environment: one </pre> So our classifier always includes base, and always sets the environment. I then invoke a puppet run on a client, specifying the environment to be *different* to the classifier. Between all of these runs I delete cached client yaml info on the server. (find /var/puppet/yaml -type f -delete) <pre> # puppetd -t --environment two notice: hardwired one notice: //base/Notify[hardwired one]/message: defined 'message' as 'hardwired one' notice: variable two notice: //base/Notify[variable two]/message: defined 'message' as 'variable two' notice: Finished catalog run in 0.18 seconds # cat /tmp/environment_test two </pre> *So we have the class being evaluated in environment "one", but the file being sourced coming from environment "two" ! *And less importantly, $environment evaluates to "two". * * Now, to throw the big spanner in the works.... we try not specifying an environment at all. <pre> # puppetd -t notice: hardwired one notice: //base/Notify[hardwired one]/message: defined 'message' as 'hardwired one' notice: variable production notice: //base/Notify[variable production]/message: defined 'message' as 'variable production' err: //base/File[/tmp/environment_test]: Failed to retrieve current state of resource: Error 400 on SERVER: Not authorized to call find on /file_metadata/base/tester Could not retrieve file metadata for puppet:///base/tester: Error 400 on SERVER: Not authorized to call find on /file_metadata/base/tester at /etc/puppet/environments/one/modules/base/manifests/init.pp:6 notice: Finished catalog run in 0.08 seconds </pre> As we don't have an environment "production" defined at all, the server tries to read the metadata from a non-existent environment and fails. -- You have received this notification because you have either subscribed to it, or are involved in it.
