+ Define secrets to be used by chart.
+ Every secret has a type which is one of:
+ - generic:
+ Generic secret template that allows to input some raw data (from files).
+ File Input can be passed as list of files (filePaths) or as a single string
+ (filePath)
+ - genericKV:
+ Type of secret which allows you to define a list of key value pairs.
+ The list is assiged to envs value. Every item may define below items:
+ - name:
+ Identifier of this value within secret
+ - value:
+ String that defines a value associated with given key.
+ This can be a simple string or a template.
+ - policy:
+ Defines what to do if value is not provided by the user.
+ Available options are:
+ - generate:
+ Generate a value by derriving it from master password
+ - required:
+ Fail the deployment
+ - password:
+ Type of secret that holds only the password.
+ Only two items can be defined for this type:
+ - password:
+ Equivalent of value field from genericKV
+ - policy:
+ The same meaning as for genericKV policy field
+ - basicAuth:
+ Type of secret that holds both username and password.
+ Below fields are available:
+ - login:
+ The value for login key.
+ This can be a simple string or a template.
+ Providing a value for login is always required.
+ - password:
+ The value for password key.
+ This can be a simple string or a template.
+ - passwordPolicy:
+ The same meaning as the policy field in genericKV.
+ Only the policy for password can be set.
+
+ Every secret can be identified using:
+ - uid:
+ A string to be appended to the chart fullname to generate a secret name.
+ - name:
+ Overrides default secret name generation and allows to set immutable
+ and globaly unique name
+
+ To allow sharing a secret between the components and allow to pre-deploy secrets
+ before ONAP deployment it is possible to use already existing secret instead of
+ creating a new one. For this purpose externalSecret field can be used. If value of
+ this field is evaluated to true no new secret is created, only the name of the
+ secret is aliased to the external one.
+
+ Example usage:
+ secrets.yaml:
+ {{ include "common.secret" . }}
+
+ values.yaml:
+ mysqlLogin: "root"
+
+ mysqlExternalSecret: "some-other-secret-name"
+
+ secrets:
+ - uid: "mysql"
+ externalSecret: '{{ tpl .Values.passExternalSecret . }}'
+ type: basicAuth
+ login: '{{ .Values.mysqlLogin }}'
+ mysqlPassword: '{{ .Values.mysqlPassword }}'
+ passwordPolicy: generate
+
+ In the above example new secret is not going to be created.
+ Already existing one (some-other-secret-name) is going to be used.
+ To force creating a new one, just make sure that mysqlExternalSecret
+ is not set.
