Docker ELK / Elastic Stack Development Tools

These are tools to run a containerized version of ELK stack, comprising of Logstash, Elastic Search, and Kibana.

A copy of the license is in docs/licenses/docker-elk.txt

Instructions

Due to complex requirements from the elastic search container upstream, there is a prerequisite to get the containers running. The docker host machine must have the max_map_count variable increased. For a developer using docker-machine with something like VirtualBox of VMWare, this can be done by getting via bash in the running Docker machine. Example:

docker-machine ssh default sudo sysctl -w vm.max_map_count=262144

After this, the containers can be started up with commands like:

make docker-compose-elk

make docker-compose-cluster-elk

These are ran from the root folder of the ansible-tower repository.

Kibana is the visualization service, and it can be accessed in a web browser by going to {server address}:5601.

Authentication

The default HTTPS logstash configuration makes use of basic auth, so a username and password is needed in HTTPS configuration, in addition to the other parameters. The following settings are supported:

{
    "LOG_AGGREGATOR_HOST": "logstash",
    "LOG_AGGREGATOR_PORT": 8085,
    "LOG_AGGREGATOR_TYPE": "logstash",
    "LOG_AGGREGATOR_USERNAME": "awx_logger",
    "LOG_AGGREGATOR_PASSWORD": "workflows",
    "LOG_AGGREGATOR_LOGGERS": [
        "awx",
        "activity_stream",
        "job_events",
        "system_tracking"
    ],
    "LOG_AGGREGATOR_INDIVIDUAL_FACTS": false,
    "LOG_AGGREGATOR_ENABLED": true,
    "LOG_AGGREGATOR_PROTOCOL": "https",
    "LOG_AGGREGATOR_TCP_TIMEOUT": 5
}

and

{
    "LOG_AGGREGATOR_HOST": "logstash",
    "LOG_AGGREGATOR_PORT": 8086,
    "LOG_AGGREGATOR_TYPE": "logstash",
    "LOG_AGGREGATOR_LOGGERS": [
        "awx",
        "activity_stream",
        "job_events",
        "system_tracking"
    ],
    "LOG_AGGREGATOR_INDIVIDUAL_FACTS": false,
    "LOG_AGGREGATOR_ENABLED": true,
    "LOG_AGGREGATOR_PROTOCOL": "udp",
    "LOG_AGGREGATOR_TCP_TIMEOUT": 5
}

and

{
    "LOG_AGGREGATOR_HOST": "logstash",
    "LOG_AGGREGATOR_PORT": 8087,
    "LOG_AGGREGATOR_TYPE": "logstash",
    "LOG_AGGREGATOR_LOGGERS": [
        "awx",

    "LOG_AGGREGATOR_TCP_TIMEOUT": 5
}

These can be entered via Configure-Tower-in-Tower by making a POST to /api/v2/settings/logging/.

Connecting Logstash to 3rd Party Receivers

In order to send these logs to an external consumer of logstash format messages, replace the output variables in the logstash.conf file.

output {
	elasticsearch {
		hosts => "elasticsearch:9200"
	}
}
