Logger
Provides a logger with different formatter and shipper. By default it logs to stdoutm but you can use log shipping to Logz.io as well.
# Functions
appendContextValues adds passed values to context fo given logger.
AppendFromLambdaContext appends some values from given context, e.g.
DefaultContextForK8s returns a log context with kubernetes node and pod name if both has benn set as K8S_NODE_NAME and K8S_POD_NAME during deployment.
DefaultContextForNodes returns a log context with hostname and ip (v4).
LogContextWithValues adds passed log values to passed context.
LogLevelByName will try to convert passed name of a log level into a log level.
LogLevelFromConfig reads log level from config using "log.loglevel" as key.
LogLevelFromEnv will lookup for environment variable defined by ENV_LOGLEVEL and if it exists call LogLevelByName to convert it's value to a log level.
NewLogger returns a new logger with passed log level, formatter and shipper.
NewLoggerFromConfig returns a new logger created depending on passed config.
WithK8sContext appends kubernetes values from environment variables as context At the moment following environment variables are supported: K8S_NODE_NAME - Node name K8S_POD_NAME - Pod name.
WithNameSpace appends passed namespace as log context.
