Follow up from 2013-01-20:
- (re-)create message file per object?
- yes, but do not necessarily save in object space
- save $anywhere
- object_run
- current notifications are imported into a file available at $__messages_in
- after object run, everything that has been written to $__messages_out is merged into the $__messages file
- functions:
self.explorer.run_global_explorers(self.local.global_explorer_out_path)
self.manifest.run_initial_manifest(self.local.initial_manifest)
self.local.run_script(initial_manifest, env=self.env_initial_manifest(initial_manifest))
self.explorer.run_type_explorers(cdist_object)
self.manifest.run_type_manifest(cdist_object)
self.local.run_script(type_manifest, env=self.env_type_manifest(cdist_object))
self.code.run_gencode_local(cdist_object)
self.local.run_script(script, env=env, return_output=True)
self.code.run_gencode_remote(cdist_object)
self.local.run_script(script, env=env, return_output=True)
- message support in ...
- initialmanifest - yes
- explorer - no
- only locally - yes
- how to use notification / messaging in cdist
- can be used in all local scripts:
- initial manifest
- type manifest
- type gencode-*
- order of object exeution is random or as you requested using require=""
- example use:
__file/gencode-local:
if [ "$local_cksum" != "$remote_cksum" ]; then
echo "$__remote_copy" "$source" "${__target_host}:${destination}"
echo "copy" >> "$__messages_out"
fi
__nginx/manifest:
__file /etc/nginx/sites-enabled/myfile --source "$__type/files/nginx-config"
__nginx/gencode-remote:
if grep -q "__file/etc/nginx/sites-enabled/myfile:copy" "$__messages_in"; then
echo /etc/init.d/nginx restart
fi
