By attribute “roles” do you mean the
attributes(override) in your role you mentioned in your previous
email.? ([aerohive_webapp][wars_array][hm-webapp.war][..])
If yes, I had a similar case and I used the -j option. (painful).
you can create a .json file and pass it to chef-client
(chef-client -j hotfix.json). In the json file you can mention
only the roles/recipes you want to update, as well as the
attributes. It's as good as editing your role file, but helps for
a quick fix.
let me know

Hi Danjib,
If I use “-o” in chef-client, Not only the run
list, but also the attribute “roles” in chef server be
overwritten. The integration which depend on attribute
“roles” may broken.

Subject: [chef] Re: Chef Role and integration
if you invoke
chef-client with -o , the override option, it should not
save the node data back (iirc). you have to check no
recipes or other code does not use node.save explicitly ,
im curious why you
dont want to run the complete run list (all the roles+
extra recipes), is performance (time) a concern ?

Hello,
we have several roles defined for
different type of servers, like DB, web, rabbitmq,
redis. and the integration is depend on roles, such
as how the WEB server find the DB servers. in each
role, there are cookbooks or sub roles in 3 layers,
there are cookbooks for system, cookbooks for
install tomcat/database, cookbooks to install war
packages. But in some case, I just need to run the
cookbooks for system or just need to deploy the war
package, the easiest way is to change the run-list,
but it changes the roles attribute in chef server
which integration depend on. Any tips on my issue.
A typical role definition:
{
"name": "hmweb",
"chef_type": "role",
"json_class": "Chef::Role",
"description": "for web application deployment,
include hm-webapp",
"override_attributes": {
"aerohive_webapp": {
"wars_array": {
"hm-webapp.war": {
"name": "hm-webapp",
"url": "http://nexus-nms.aerohive.com/service/local/artifact/maven/redirect?r=hive-repository&g=com.aerohive.nms.web&a=hm-webapp&e=war&v=1.0-SNAPSHOT"
},
"sysmgr-regional-webapp.war": {
"name": "sysmgr-regional-webapp",
"url": "http://nexus-nms.aerohive.com/service/local/artifact/maven/redirect?r=hive-repository&g=com.aerohive.nms&a=sysmgr-regional-webapp&e=war&v=1.0-SNAPSHOT"
}
},
"service_log_enabled": "true"
}
},
"run_list": [
"role[_base]",
"role[_webappbase]",
"recipe[aerohive-webapp::deploy]"
]
}
