Docker

How to use this image

Starting a pubsub instance:

docker run --name my-pubsub -e QUEUE_BUFFER_SIZE=100 -d vardius/pubsub:tag

Environment Variables

HOST (string)

This is optional variable, sets gRPC server host value. Default 0.0.0.0

PORT (int)

This is optional variable, sets gRPC server port value. Default 9090

QUEUE_BUFFER_SIZE (int)

This is optional variable, sets buffered channel length per subscriber. Default 0, which evaluates to runtime.NumCPU().

KEEPALIVE_MIN_TIME

This is optional variable, if a client pings more than once every 5 minutes (default), terminate the connection. ParseDuration parses a duration string. A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as 300ms, -1.5h or 2h45m. Valid time units are ns, us (or µs), ms, s, m, h

KEEPALIVE_TIME (nanoseconds)

This is optional variable, ping the client if it is idle for 2 hours (default) to ensure the connection is still active. ParseDuration parses a duration string. A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as 300ms, -1.5h or 2h45m. Valid time units are ns, us (or µs), ms, s, m, h

KEEPALIVE_TIMEOUT (nanoseconds)

This is optional variable, wait 20 second (default) for the ping ack before assuming the connection is dead. ParseDuration parses a duration string. A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as 300ms, -1.5h or 2h45m. Valid time units are ns, us (or µs), ms, s, m, h

LOG_VERBOSE_LEVEL (int)

This is optional variable, Verbose level. -1 = Disabled, 0 = Critical, 1 = Error, 2 = Warning, 3 = Info, 4 = Debug. Default 3 (Info).
