Issue #3910 has been updated by Nigel Kersten.
Let me flesh out the proposal. We have a setting for whether the master is authoritative over the client environment. Server authoritative: * Server sets environment and client sets environment, produce warning client/server side, use server env. * Server does not set environment, client does, use client env. * Server sets environment, client does not, use server env. Server not authoritative: * Server sets environment and client sets environment, produce warning server-side, use client env. * Server does not set environment, client does, use client env. * Server sets environment, client does not, use server env. This does all assume that the idea of a "default" environment goes away client-side. I don't see that being a huge problem, as users can simply set their default environment on the server, and they can still choose whether or not the server is authoritative. Am I missing some use cases ? ---------------------------------------- Bug #3910: Class/File source mismatch when client/node classifier disagree on environment. https://projects.puppetlabs.com/issues/3910 Author: Nigel Kersten Status: Needs design decision Priority: High Assignee: Nigel Kersten Category: plumbing Target version: Statler Affected Puppet version: 0.25.4 Keywords: Branch: 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.
