Functions ¶
func ConvertIAMError ¶
ConvertIAMError converts common errors from IAM clients to trace errors.
func ConvertRequestFailureError ¶
ConvertRequestFailureError converts `error` into AWS RequestFailure errors to trace errors. If the provided error is not an `RequestFailure` it returns the error without modifying it.
func IsTagValueTrue ¶
IsTagValueTrue checks whether a tag value is true.
Types ¶
type Identity ¶
type Identity interface {
// GetName returns the identity name.
GetName() string
// GetAccountID returns the AWS account ID the identity belongs to.
GetAccountID() string
// GetPartition returns the AWS partition the identity resides in.
GetPartition() string
// GetType returns the identity resource type.
GetType() string
// Stringer provides textual representation of identity.
fmt.Stringer
}
Identity represents an AWS IAM identity such as user or role.
func GetIdentityWithClient ¶
GetIdentityWithClient determines AWS identity of this Teleport process using the provided STS API client.
func IdentityFromArn ¶
IdentityFromArn returns an `Identity` interface based on the provided ARN.
type InstanceMetadataClient ¶
type InstanceMetadataClient struct {
// contains filtered or unexported fields
}
InstanceMetadataClient is a wrapper for an imds.Client.
func NewInstanceMetadataClient ¶
func NewInstanceMetadataClient(ctx context.Context, opts ...InstanceMetadataClientOption) (*InstanceMetadataClient, error)
NewInstanceMetadataClient creates a new instance metadata client.
func (*InstanceMetadataClient) GetHostname ¶
func (client *InstanceMetadataClient) GetHostname(ctx context.Context) (string, error)
GetHostname gets the hostname set by EC2 that Teleport should use, if any.
func (*InstanceMetadataClient) GetRegion ¶
func (client *InstanceMetadataClient) GetRegion(ctx context.Context) (string, error)
GetRegion gets the EC2 instance's region.
func (*InstanceMetadataClient) GetType ¶
func (client *InstanceMetadataClient) GetType() types.InstanceMetadataType
GetType gets the cloud instance type.
func (*InstanceMetadataClient) IsAvailable ¶
func (client *InstanceMetadataClient) IsAvailable(ctx context.Context) bool
IsAvailable checks if instance metadata is available.
type InstanceMetadataClientOption ¶
type InstanceMetadataClientOption func(client *InstanceMetadataClient) error
InstanceMetadataClientOption allows setting options as functional arguments to an InstanceMetadataClient.
func WithIMDSClient ¶
func WithIMDSClient(client *imds.Client) InstanceMetadataClientOption
WithIMDSClient adds a custom internal imds.Client to an InstanceMetadataClient.
type Policies ¶
type Policies interface {
// Upsert creates a new Policy or creates a Policy version if a policy with
// the same name already exists.
Upsert(ctx context.Context, policy *Policy) (arn string, err error)
// Retrieve retrieves a policy and its versions. If the tags list is
// present, the Policy should have all of them, otherwise an error is
// returned.
Retrieve(ctx context.Context, arn string, tags map[string]string) (policy *iam.Policy, policyVersions []*iam.PolicyVersion, err error)
// Attach attaches a policy with `arn` to the provided `identity`.
Attach(ctx context.Context, arn string, identity Identity) error
// AttachBoundary attaches a policy boundary with `arn` to the provided
// `identity`.
AttachBoundary(ctx context.Context, arn string, identity Identity) error
}
Policies set of IAM Policy helper functions defined as an interface to make easier for other packages to mock and test with it.
type Policy ¶
type Policy struct {
// Name is the policy name.
Name string
// Description is the policy description.
Description string
// Tags is the policy tags.
Tags map[string]string

Document *PolicyDocument
}
Policy represents an AWS IAM policy.
type PolicyDocument ¶
type PolicyDocument struct {
// Version is the policy version.
Version string `json:"Version"`
// Statements is a list of the policy statements.
Statements []*Statement `json:"Statement"`
}
PolicyDocument represents a parsed AWS IAM policy document.
Note that PolicyDocument and its Ensure/Delete methods are not currently goroutine-safe. To create a policy using AWS IAM API, dump the object to JSON format using json.Marshal.

Delete deletes the specified resource action from the policy.
func (*PolicyDocument) Ensure ¶
func (p *PolicyDocument) Ensure(effect, action, resource string) bool
Ensure ensures that the policy document contains the specified resource action.
Returns true if the resource action was already a part of the policy and false otherwise.
func (*PolicyDocument) Marshal ¶
func (p *PolicyDocument) Marshal() (string, error)
Marshal formats the PolicyDocument in a "friendly" format, which can be presented to end users.
type Role ¶
type Role struct {
// contains filtered or unexported fields
}
Role represents an AWS IAM role identity.
func (Role) GetAccountID ¶
func (i Role) GetAccountID() string
GetAccountID returns the identity account ID.
func (Role) GetPartition ¶
func (i Role) GetPartition() string
GetPartition returns the identity AWS partition.
type Statement ¶
type Statement struct {
// Effect is the statement effect such as Allow or Deny.
Effect string `json:"Effect"`
// Actions is a list of actions.
Actions []string `json:"Action"`
// Resources is a list of resources.
Resources []string `json:"Resource"`
}
Statement is a single AWS IAM policy statement.
