raucao 87d4305c0d scripts: add migrate_node_to_cinc.sh
One-shot, idempotent helper that prepares an existing (Chef) node for
Cinc Workstation management: installs Cinc Client, points /etc/cinc at
the existing /etc/chef config, drops the deprecated attribute lists, and
pre-seeds the allowed_* attribute lists so the first converge does not
filter node attributes (e.g. vm_host). The node can then be converged as
usual. Verified against drone-1.

This repository contains all infrastructure automation code that we use to set
up and configure servers, virtual machines, and applications for Kosmos hosted
services.
Cookbooks are written in Ruby, and based on [Chef Infra
resources](https://docs.chef.io/resources/). Some cookbooks contain integration
test suites based on [Test Kitchen](https://docs.chef.io/workstation/kitchen/).
Nodes run the community [Cinc Client](https://cinc.sh/) distribution of Chef
Infra Client instead of the license-gated Chef Infra Client. Everything — the
`knife zero` workflow and the Test Kitchen suites — is driven by
[Cinc Workstation](https://cinc.sh/docs/workstation/), and on-node
configuration lives in `/etc/cinc`.
Note: Manual configuration of servers and applications is highly discouraged,
and can be overwritten or lost without notice!
## Setup
### Install Cinc Workstation
Cinc Workstation replaces Chef Workstation. Install it following
https://cinc.sh/docs/workstation/ — or, on Arch Linux, the `cinc-workstation-bin`
AUR package. It installs to `/opt/cinc-workstation` and reads its user config
from `~/.cinc-workstation`.
#### rbenv
If you use rbenv to manage Ruby versions on your system, install the
`rbenv-cinc-workstation` plugin (the Cinc port of
[rbenv-chef-workstation](https://github.com/docwhat/rbenv-chef-workstation)),
create an empty `$(rbenv root)/versions/cinc-workstation` directory, and run
`rbenv rehash`. This repository pins the version in `.ruby-version`.
### Install knife-zero
`knife-zero` is not bundled with Cinc Workstation. Install it into Cinc's user
gem directory:
cinc gem install knife-zero
### Configure knife
Copy `.cinc/config.rb.example` to `.cinc/config.rb` and adjust
`encrypted_data_bag_secret` if your secret lives elsewhere.
## Common tasks
### Bootstrap a new host server
knife zero bootstrap root@server-name.kosmos.org --run-list "role[base],role[kvm_host]" --secret-file .cinc/encrypted_data_bag_secret
### Bootstrap a new VM
knife zero bootstrap ubuntu@zerotier-ip-address -x ubuntu --sudo --run-list "role[base],role[kvm_guest]" --secret-file .cinc/encrypted_data_bag_secret
### Bootstrap a new VM with environment and role/app (postgres replica as example)
knife zero bootstrap ubuntu@10.1.1.134 -x ubuntu --sudo --environment production --run-list "role[base],role[kvm_guest],role[postgresql_replica]" --secret-file .cinc/encrypted_data_bag_secret
### Run Chef Zero on a host server
knife zero converge -p2222 name:server-name.kosmos.org
### Run Chef Zero on a VM
knife zero converge -a knife_zero.host name:vm-name-23
### Update Cinc Client on a server
knife zero converge name:dev.kosmos.org --client-version 18.2.7
### Upgrade Cinc Client on a node
knife ssh -a knife_zero.host 'name:foo-1' 'curl -L https://omnitruck.cinc.sh/install.sh | sudo bash -s -- -v 19'
### Migrate an existing node to Cinc Client
scripts/knife/migrate_node_to_cinc.sh node-name-1 # then converge as usual
## 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
## Integration tests
Some cookbooks contain Test Kitchen suites. They are configured to run against
Cinc Client (`provisioner: product_name: cinc`) and use Cinc Workstation's
bundled `kitchen` (which ships a Cinc-capable `kitchen-dokken`):
kitchen test
(use `kitchen converge`/`verify` while iterating on a single suite).
