Package alzlib provides the data structures needed to deploy Azure Landing Zones. It contains the custom Azure policies and policy sets needed to deploy the reference architecture. It also gets the referenced built-in definitions from the Azure Policy service.

Internally the Azure SDK is used to store the resources in memory. It is up to the caller to transform this data into the required format for deployment.

Functions

func FetchAzureLandingZonesLibraryMember added in v0.14.0 

func FetchAzureLandingZonesLibraryMember(ctx context.Context, member, tag, dst string) (fs.FS, error)

FetchAzureLandingZonesLibraryByTag is a convenience function to fetch the Azure Landing Zones library by member and tag. It calls FetchLibraryByGetterString with the appropriate URL. The destination directory will be appended to the .alzlib directory in the current working directory. To fetch the ALZ reference, supply "platform/alz" as the member, with the tag (e.g. 2024.03.03).

func FetchLibraryByGetterString added in v0.14.0 

func FetchLibraryByGetterString(ctx context.Context, getterString, dstDir string) (fs.FS, error)

FetchLibraryByGetterString fetches a library from a URL using the go-getter library. The caller must supply a valid go-getter URL and a destination directory, which will be appended to the .alzlib directory in the current working directory. It returns an fs.FS interface to the fetched library to be used in the AlzLib.Init() method.

Types

type AlzLib 

type AlzLib struct {
	Options *AlzLibOptions
	// contains filtered or unexported fields
}

AlzLib is the structure that gets built from the the library files do not create this directly, use NewAlzLib instead. Note: this is not thread safe, and should not be used concurrently without an external mutex.

func NewAlzLib 

func NewAlzLib(opts *AlzLibOptions) *AlzLib

NewAlzLib returns a new instance of the alzlib library, optionally using the supplied directory for additional policy (set) definitions.

func (*AlzLib) AddPolicyAssignments added in v0.14.0 

func (az *AlzLib) AddPolicyAssignments(pas ...*assets.PolicyAssignment) error

AddPolicyAssignments adds policy assignments to the AlzLib struct.

func (*AlzLib) AddPolicyClient 

func (az *AlzLib) AddPolicyClient(client *armpolicy.ClientFactory)

AddPolicyClient adds an authenticated *armpolicy.ClientFactory to the AlzLib struct. This is needed to get policy objects from Azure.

func (*AlzLib) AddPolicyDefinitions added in v0.14.0 

func (az *AlzLib) AddPolicyDefinitions(pds ...*assets.PolicyDefinition) error

AddPolicyDefinitions adds policy definitions to the AlzLib struct.

func (*AlzLib) AddPolicySetDefinitions added in v0.14.0 

func (az *AlzLib) AddPolicySetDefinitions(psds ...*assets.PolicySetDefinition) error

AddPolicySetDefinitions adds policy set definitions to the AlzLib struct.

func (*AlzLib) AddRoleDefinitions added in v0.14.0 

func (az *AlzLib) AddRoleDefinitions(rds ...*assets.RoleDefinition) error

AddRoleDefinitions adds role definitions to the AlzLib struct.

func (*AlzLib) Archetype added in v0.14.0 

func (az *AlzLib) Archetype(name string) (*Archetype, error)

Archetype returns a copy of the requested archetype by name. The returned struct can be used as a parameter to the Deployment.AddManagementGroup method.

func (*AlzLib) Archetypes added in v0.14.0 

func (az *AlzLib) Archetypes() []string

Archetypes returns a list of the archetypes in the AlzLib struct.

func (*AlzLib) Architecture added in v0.14.0 

func (az *AlzLib) Architecture(name string) (*Architecture, error)

Architecture returns the requested architecture.

func (*AlzLib) GetDefinitionsFromAzure 

func (az *AlzLib) GetDefinitionsFromAzure(ctx context.Context, pds []string) error

GetDefinitionsFromAzure takes a slice of strings containing Azure resource IDs of policy definitions and policy set definitions. It then fetches them from Azure if needed and adds them to the AlzLib struct. For set definitions we need to get all of them, even if they exist in AlzLib already because they can contain built-in definitions.

func (*AlzLib) Init 

func (az *AlzLib) Init(ctx context.Context, libs ...fs.FS) error

Init processes ALZ libraries, supplied as fs.FS interfaces. Use FetchAzureLandingZonesLibraryMember to get the library from GitHub. It populates the struct with the results of the processing.

func (*AlzLib) PolicyAssignment added in v0.14.0 

func (az *AlzLib) PolicyAssignment(name string) (*assets.PolicyAssignment, error)

GetPolicySetDefinition returns a deep copy of the requested policy set definition. This is safe to modify without affecting the original.

func (*AlzLib) PolicyAssignmentExists 

func (az *AlzLib) PolicyAssignmentExists(name string) bool

PolicyAssignmentExists returns true if the policy assignment exists in the AlzLib struct.

func (*AlzLib) PolicyDefinition added in v0.14.0 

func (az *AlzLib) PolicyDefinition(name string) (*assets.PolicyDefinition, error)

PolicyDefinition returns a deep copy of the requested policy definition. This is safe to modify without affecting the original.

func (*AlzLib) PolicyDefinitionExists 

func (az *AlzLib) PolicyDefinitionExists(name string) bool

PolicyDefinitionExists returns true if the policy definition exists in the AlzLib struct.

func (*AlzLib) PolicySetDefinition added in v0.14.0 

func (az *AlzLib) PolicySetDefinition(name string) (*assets.PolicySetDefinition, error)

PolicySetDefinition returns a deep copy of the requested policy set definition. This is safe to modify without affecting the original.

func (*AlzLib) PolicySetDefinitionExists 

func (az *AlzLib) PolicySetDefinitionExists(name string) bool

PolicySetDefinitionExists returns true if the policy set definition exists in the AlzLib struct.

func (*AlzLib) RoleDefinition added in v0.14.0 

func (az *AlzLib) RoleDefinition(name string) (*assets.RoleDefinition, error)

RoleDefinition returns a deep copy of the requested role definition. This is safe to modify without affecting the original.

func (*AlzLib) RoleDefinitionExists 

func (az *AlzLib) RoleDefinitionExists(name string) bool

RoleDefinitionExists returns true if the role definition exists in the AlzLib struct.

type AlzLibOptions 

type AlzLibOptions struct {
	AllowOverwrite bool // AllowOverwrite allows overwriting of existing policy assignments when processing additional libraries with AlzLib.Init()
	Parallelism    int  // Parallelism is the number of parallel requests to make to Azure APIs
}

AlzLibOptions are options for the AlzLib. This is created by NewAlzLib.

type Archetype 

type Archetype struct {
	PolicyDefinitions    mapset.Set[string]
	PolicyAssignments    mapset.Set[string]
	PolicySetDefinitions mapset.Set[string]
	RoleDefinitions      mapset.Set[string]
	// contains filtered or unexported fields
}

Archetype represents the exported archetype definition that hasn't been assigned to a management group The contents of the sets represent the map keys of the corresponding AlzLib maps.

func NewArchetype added in v0.14.0 

func NewArchetype(name string) *Archetype

func (*Archetype) Name added in v0.14.0 

func (a *Archetype) Name() string

type Architecture added in v0.14.0
