Install Chef Workstation

rbenv

If you use rbenv to manage Ruby versions on your system, install the (rbenv-chef-workstation)[https://github.com/docwhat/rbenv-chef-workstation] plugin.

Install gem dependencies

bundle install

Bootstrap a new server

knife zero bootstrap root@dev.kosmos.org --run-list "recipe[kosmos-base],..." -j '{"example_cookbook":{"memory_max":"256M"}}' --secret-file .chef/encrypted_data_bag_secret

Bootstrap a new VM

knife zero bootstrap ubuntu@zerotier-ip-address -x ubuntu --sudo --run-list "recipe[kosmos-base]" --secret-file .chef/encrypted_data_bag_secret

Run Chef Zero

knife zero converge name:dev.kosmos.org

Run Chef Zero on a VM

knife zero converge -a knife_zero.host name:vm-name-23

Update Chef Client on a server:

knife zero converge name:dev.kosmos.org --client-version 15.3.14

Managing cookbooks

Cookbooks are managed via Berkshelf. Run berks --help for command help.

Install cookbooks listed in Berksfile:

berks install

Vendor installed cookbooks to the cookbooks/ dir:

berks vendor cookbooks/ --delete

"Expired" TLS certificates

If you encounter expired TLS certificates during a Chef run (e.g. for remote files), the issue is likely that the certificate has been issued by Let's Encrypt and Chef is still using its own, outdated CA cert store (see here for example).

As a hotfix, you can manually remove the "DST Root CA X3" cert from /opt/chef/embedded/ssl/cert.pem on the machine you're trying to converge.
