Wait for an HTTP server to come online and optionally warm it up with a specified number of requests
301
Python script / Docker image that waits for an HTTP server to come online and optionally warms it up by sending some requests to it.
This can be used to warm up a web server before starting to redirect real HTTP requests from users, when doing zero downtime deployments.
Wait for a host to reply with an HTTP 2xx response:
docker run --rm -it heyman/http-warmup https://example.org
Send 20 warm-up requests using three threads once the server has come alive:
docker run --rm -it heyman/http-warmup --warmup-requests=20 --warmup-threads=3 https://example.org
Set the max time that we should wait for the server to come alive to 5 minutes:
docker run --rm -it heyman/http-warmup --timeout=300 https://example.org
Usage: warmup.py [OPTIONS] URLS...
At least one URL must be specified. The first URL is pinged until it returns
a 2xx HTTP response.
If --warmup-requests is used the URLs will be round robin picked from all
specified URLS
Options:
--timeout INTEGER Number of seconds to wait for the host to come
online. Default: 60
--warmup-requests INTEGER Number of warm-up requests to send. Default: 0
--warmup-threads INTEGER Number of threads used to send the warm-up
requests. Default: 1
--request-timeout INTEGER Request timeout for individual HTTP requests.
Default: 5
--hostname TEXT Overrides the `Hostname` HTTP request header if
specified
-v, --verbose
--help Show this message and exit.
