description: A Helm chart for Kubernetes
|
||||
|

# A chart can be either an 'application' or a 'library' chart.
|
||||
#
|
||||
# Application charts are a collection of templates that can be packaged into versioned archives
|
||||
# to be deployed.
|
||||
#
|
||||
# Library charts provide useful utilities or functions for the chart developer. They're included as
|
||||
# a dependency of application charts to inject those utilities and functions into the rendering
|
||||
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
|
||||
type: application
|
||||
|
||||
# This is the chart version. This version number should be incremented each time you make changes
|
||||
# to the chart and its templates, including the app version.
|
||||
# Versions are expected to follow Semantic Versioning (https://semver.org/)
|
||||
version: 0.1.0
|
||||
|
||||
# This is the version number of the application being deployed. This version number should be
|
||||
# incremented each time you make changes to the application. Versions are not expected to
|
||||
# follow Semantic Versioning. They should reflect the version the application is using.
|
||||
# It is recommended to use it with quotes.

|
||||
- `ansible all -i inventory/hosts.yml --list-hosts`
|
||||
- `ansible all -i inventory/hosts.yml -m ping`
|
||||
- `pushd ansible && ansible all -i inventory/hosts.yml --list-hosts`
|
||||
- `pushd ansible && ansible all -i inventory/hosts.yml -m ping`
|
||||
- Use Ansible to build the cluster as configured on all nodes (from `./ansible`)
|
||||
- `ansible-playbook -i inventory/hosts.yml ./build-k3s-cluster`
|
||||
- `pushd ansible && ansible-playbook -i inventory/hosts.yml ./build-k3s-cluster.yml`
|
||||
|

And the cluster is up! If you want to interact with it from your controller,
|

you can do this:
