Functions

func DetectEKSClusterName

func DetectEKSClusterName(ctx context.Context, cfg aws.Config) (string, error)

func MergeTags

func MergeTags(tagMaps ...map[string]string) map[string]string

MergeTags merges all tags into a newly created map. Duplicate tags are overwritten by rightmost argument.

func NewConfig

func NewConfig(ctx context.Context) (aws.Config, error)

NewConfig returns a new aws.Config configured with the correct region + endpoint resolver

func NewSubnetsFilters

func NewSubnetsFilters(tags map[string]string, ids []string) []ec2_types.Filter

NewSubnetsFilters transforms a map of tags and values and a slice of subnets into a slice of ec2.Filter adequate to filter AWS subnets.

func NewTagsFilter

func NewTagsFilter(tags map[string]string) []ec2_types.Filter

NewTagsFilter transforms a map of tags and values into a slice of ec2.Filter adequate to filter resources based on tags.
