Wait for HTTP Service to become available with timeout (bash)
Raw
readme.md 
timeout 40s /bin/bash -c "while ! httping -qc1 http://somehost:8080/app ; do sleep 1 ; done; echo OK" || echo TIMEOUT

If the service cannot be reached within 40s then TIMEOUT will be printed otherwise OK.

Very cool!

If one instead wants to use curl to check the HTTP status code, then the git could be adapted to:

timeout 40s bash -c 'while [[ $(curl -s -o /dev/null -w %{http_code} http://somehost:8080/app) != 200 ]]; do sleep 1; done; echo OK' || echo TIMEOUT
