nakosung/docker-logstash repository overview

⁠About:

Docker⁠ image based on digitalwonderland/base⁠

⁠Additional Software:

• Logstash⁠

⁠Logstash Configuration:

⁠Elasticsearch Connection

To connect to Elasticsearch Logstashs elasticsearch_http output⁠ is used (this allows for greater flexibility regarding the compatible Elasticsearch versions). Hostname and port can be configured via the ELASTICSEARCH_PORT_9200_TCP_ADDR and ELASTICSEARCH_PORT_9200_TCP_PORT environment variables. They default to elasticsearch and 9200 respectively.

⁠Logstash Inputs

The following inputs are enabled:

• logstash-forwarder⁠ on port 5043 & certificates being available in a volume bellow /mnt/logstash-forwarder.
• tcp⁠ on port 3333
• syslog⁠ on port 1514. You might want to map that to 514 on the host (it had to be above 1024 since logstash is not running as root)
