This cookbook installs and upgrades Chef Server clusters as defined in Chef Docs. The recipes aim to follow the same procedures and commands in the prescribed sequences. Since the docs are manual instructions, it should be understood that the recipes verify the published installation process versus an optimized automated solution.
This includes:
- Chef Server 12
- Enterprise Chef
- Open Source Chef
- Addons
- Standalone, Tier, HA topologies
- Ubuntu and RHEL platforms
See the Provisioning Paths doc for additional details.
- AWS account and config
- chefdk
berks vendor
# default config
chef-client -z -o qa-chef-server-cluster::<recipe>
# attribute overrides
chef-client -z -j <attrs>.json -o qa-chef-server-cluster::<recipe>
Current supported topologies are standalone-server, tier-cluster and ha-cluster.
<topology>: Creates and install the initial cluster
<topology>-upgrade: Upgrades an existing cluster
<topology>-generate-test-data: Loads data using Chef Server Data Generator
<topology>-test: Executes cluster tests (currently runs pedant)
<topology>-destroy: Destroys the cluster
<topology>-logs: Runs chef-server-ctl gather-logs, and downloads the archives and any error logs (chef-stacktrace.out)
Note: the install and upgrade provision recipes download logs during execution. This is intended to be used on-demand.
ha-cluster-trigger-failover: Triggers an HA failover and verifies backend statuses. (Currently only fails over from initial bootstrap for Chef Server versions.)
ha-enterprise-chef-ha-cluster: Installs EC HA clusters. NOTE: recommend using m3.large instance types for EC HA clusters.
ha-enterprise-chef-ha-cluster-upgrade: Upgrades EC HA clusters
The cookbook provisions two specific paths for installing new servers and upgrading servers rather than a single provisioning point of entry. This was done for the following reasons:
- The Chef Docs define explicit install and upgrade paths, and it was important to maintain parity
- Allows installs to run again if an error is encountered without the risk of accidentally running upgrade procedures
- Allows devs to insert custom steps and different stages of the install/upgrade process like loading data, custom config, tools, etc.
The machine resources and other cluster-associated provisioning resources (ebs volumes, etc) will need to have unique names in order for a chef-repo to support multiple instances of topology clusters. Override the ['qa-chef-server-cluster']['provisioning-id'] attibute. The default is default.
| topology | resource | name |
|---|---|---|
| Standalone | machine | id-standalone |
| Tier | machine | id-tier-bootstrap-backend id-tier-frontend |
| HA | machine | id-ha-bootstrap-backend id-ha-secondary-backend id-tier-frontend |
| HA | aws_ebs_volume, aws_eni | id-ha |
