I have started the fluentd server with docker.My fluentd configuration is
<source> @type syslog port 514 bind 0.0.0.0 tag system </source> <match **> @type stdout </match> The command I used to start the fluentd server is
docker run -p 514:514 -v $(pwd)/tmp:/fluentd/etc fluent/fluentd:edge-debian -c /fluentd/etc/fluentd.conf It starts the server successfully and I get the log

import logging import logging.handlers import socket if __name__ == "__main__": syslogger = logging.getLogger('SyslogLogger') handler = logging.handlers.SysLogHandler(address=("0.0.0.0", 514), facility=19, socktype=socket.SOCK_DGRAM) syslogger.addHandler(handler) syslogger.info("Hello World") Script runs without any error but I don't get any log on the on the fluentd.
Server and script both are on a local machine.
httpsource but in the logs the loaded config is showingsyslogsource. And, the port you're using withdockeris 9880, not 514. For a simpler setup, you can test this on your local machine first and then move on to docker to emulate the same.http->syslogand using correct port in docker container. I copied the wrong config file while creating the question. Still the issue is the same.
