description "Use the **habitat_sup** resource to runs a Chef Habitat supervisor for one or more Chef Habitat services. The resource is commonly used in conjunction with `habitat_service` which will manage the services loaded and started within the supervisor."
introduced "17.3"
examples <<~DOC
**Set up with just the defaults**
```ruby
habitat_sup 'default'
```
**Update listen ports and use Supervisor toml config**
```ruby
habitat_sup 'test-options' do
listen_http '0.0.0.0:9999'
listen_gossip '0.0.0.0:9998'
toml_config true
end
```
**Use with an on-prem Habitat Builder. Note: Access to public builder may not be available due to your company policies**
```ruby
habitat_sup 'default' do
bldr_url 'https://bldr.private.net'
end
```
**Using update_condition**
```ruby
habitat_sup 'default' do
bldr_url 'https://bldr.private.net'
habitat_channel 'dev'
update_condition 'track-channel'
end
```
**Provide event_stream_* information**
```ruby
habitat_sup 'default' do
license 'accept'
event_stream_application 'myapp'
event_stream_environment 'production'
event_stream_site 'MySite'
event_stream_url 'automate.private.net:4222'
event_stream_token 'myawesomea2clitoken='
event_stream_cert '/hab/cache/ssl/mycert.crt'
end
```
**Provide specific versions**
```ruby
habitat_sup 'default' do
bldr_url 'https://bldr.private.net'
sup_version '1.5.50'
launcher_version '13458'
service_version '0.6.0' # WINDOWS ONLY
end
```
**Set latest version of packages to retain**
habitat_sup 'default' do
bldr_url 'https://bldr.private.net'
sup_version '1.5.86'
launcher_version '13458'
service_version '0.6.0' # WINDOWS ONLY
keep_latest '2'

- `latest`: Runs the latest package that can be found in the configured channel and local packages.
- `track-channel`: Always run what is at the head of a given channel. This enables service rollback where demoting a package from a channel will cause the package to rollback to an older version of the package. A ramification of enabling this condition is packages newer than the package at the head of the channel will be automatically uninstalled during a service rollback."
