hosts.yaml

The servers for components deployed by ansible should be kept under targets/<target>/<zone>/hosts.yaml. This hosts.yaml is essentially an yaml formated hosts inventory recognized by Ansible.

How to change SSH for a host

all:
  vars:
    ansible_user: root
    ansible_port: 22
somegroupname:
  vars:
    ansible_user: root
    ansible_port: 22
  hosts:
    10.0.0.1:
      ansible_user: root
      ansible_port: 2222

If the SSH addr for the host is not equal to the keys under the hosts field, you can set it to other address by setting ansible_host for the host.

somegroupname:
  hosts:
    10.0.0.1:
      ansible_user: root
      ansible_port: 2222
      ansible_host: 127.0.0.1

platforms.yaml

The k8s platform information for components deployed by helm should be kept under targets/<target>/<zone>/platforms.yaml.

Generally, all components of a product is deployed to one namespace under a K8S cluster. In this case, you just needs to set one all record in platforms.yaml.

all:
  k8s:
    kubeConfig: ~/.kube/config
    kubeContext: ""
    namespace: default

But, if the components are needed to deployed to different namespaces or different K8S cluster, you can set seperated k8s information for each component.

all:
  k8s:
    kubeConfig: ~/.kube/config
    kubeContext: ""
    namespace: default

component-name1:
  k8s:
    kubeConfig: ~/.kube/config
    kubeContext: ""
    namespace: another

component-name2:
  k8s:
    kubeConfig: ~/.kube/config
    kubeContext: ""
    namespace: another

The all record is used for all other components which are not explicitly defined.
