README.MD

This is a small HTTP server that sends back the incoming request with all the metadata in response, including the sender's IP address, all request parameters, and headers. The server's configuration can be modified by using environment variables:

  • SERVER_NAME: The name of the server.
  • SRV_PORT: The port on which the server is running.
  • METRIC_PORT: The port where server metrics are available in Prometheus format.
  • ENABLE_OUTPUT: log to stdout (default = "true")
  • LOG_PATH: write logs to file ${LOG_PATH} (default="" without file output)
  • ENABLE_LOAD_MEMORY : enable memory usage (default=false)
  • MEMORY_USAGE_PROFILE: additional memory usage and time for usage . example 5=10 7=60 1024=360 - 5 Mb 10sec 7 Mb 60sec 1024Mb 360sec
  • ENABLE_LOG_LOAD_MEMORY: logs LOAD_MEMORY function
  • ENABLE_LOAD_CPU : enable cpu usage (default=false)
  • ENABLE_LOG_LOAD_CPU: logs LOAD_CPU function
  • CPU_USAGE_PROFILE: additional CPU usage iteraction_milion=wait_msec=gorutins=time_sec . example 10=1=1=30 1=400=1=60
  • CPU_MAXPROC: GOMAXPROCS (default = 1)

You can view the current metrics at {server_address}:{METRIC_PORT}/metrics.

examples

run http pingPong server

kubectl  run test -n circleci --image  viktoruj/ping_pong

run http pingPong server with serverName

kubectl  run test -n circleci --image  viktoruj/ping_pong  --env SERVER_NAME=pingPongServer

run http pingPong server with MEMORY_USAGE

kubectl  run test -n circleci --image  viktoruj/ping_pong   --env MEMORY_USAGE_PROFILE='5=60  20=60   1024=360    ' --env ENABLE_LOAD_MEMORY=true

run http pingPong server with MEMORY_USAGE and CPU_USAGE and enable cpu and memory loging . It uses CPU_MAXPROC =2 .

kubectl  run test  --image  viktoruj/ping_pong  --env CPU_USAGE_PROFILE='1=400=1=60 1=4=1=60 10=1=4=60'  --env ENABLE_LOAD_CPU=true  --env ENABLE_LOG_LOAD_CPU=true --env CPU_MAXPROC=2 --env MEMORY_USAGE_PROFILE='5=60  20=60   1024=360  ' --env ENABLE_LOAD_MEMORY=true --env ENABLE_LOG_LOAD_MEMORY=true
