Functions

func GetAccountId 

func GetAccountId(metaEndPoint string, useRegionalSTS bool, region string) (string, error)

func GetInstanceTagValue added in v1.11.22 

func GetInstanceTagValue(metaEndPoint, tagKey string) (string, error)

func GetRunsAsUidGid added in v1.10.52 

func GetRunsAsUidGid(opts *Options) (int, int)

GetRunsAsUidGid returns the uid/gid that the tool should continue to run as based on the configured setup. For example, if all services have been configured to have the same uid/gid for keys and certs, then the tool can drop its access from root to the specified user. If they're multiple users defined then the return values would be -1/-1

func GetSvcNames 

func GetSvcNames(svcs []Service) string

GetSvcNames returns comma separated list of service names

func InitCredsConfig 

func InitCredsConfig(roleSuffix, accessProfileSeparator string, useRegionalSTS bool, region string) (*ConfigAccount, *AccessProfileConfig, error)

func InitEnvConfig 

func InitEnvConfig(config *Config) (*Config, *ConfigAccount, error)

func InitFileConfig 

func InitFileConfig(fileName, metaEndPoint string, useRegionalSTS bool, region, account string) (*Config, *ConfigAccount, error)

func InitProfileConfig 

func InitProfileConfig(metaEndPoint, roleSuffix, accessProfileSeparator string) (*ConfigAccount, *AccessProfileConfig, error)
