[chef] Re: Re: Environments & Databags

With Chef solo using roles and run lists.

Here for example is a base role (configure apt, email etc) and www role (nginx etc)

% ls -1 roles 

base.json

www.json

www_develop_branch.json

www_master_branch.json

If the node is in staging it's on the develop (git) branch and adds the www_develop_branch role to it's run list.

If the node is in productution it's on the masterp (git) branch and adds the www_master_branch role to it's run list.

nodes/dev.www.com.json run_list:

"run_list": [

  "role[base]",

  "role[www]",

  "role[www_develop_branch]"

]

nodes/www.com.json run_list:

"run_list": [

  "role[base]",

  "role[www]",

  "role[www_master_branch]"

]

The www_master_branch would have production server only recipes like "datadog" and "mongodb mms" for monitoring.

Seems to work OK for us - this is for small apps using Chef solo.

We have different data bags for different logical partitions (e.g. one for each application), and inside the data bags are items with names corresponding to our chef environments.

We used to just have different data bags for different environments and use the environment attribute to determine which data bag was hit with the query dynamically.

I liked that better than having items mixed up in the same data bag, but each partitioning comes with its own pros and cons.

A pattern we use is:

  data_bags/
      users/
          prod.json
          preprod.json

So anything that needs environment specific settings gets an environment
specific data bag item.

Recipe code can then select the right data bag item via the node's
chef_environment attribute.
