DOCKER SYSLOG LOGSTASH HOW TO

If the message was in JSON format, it will be processed. Now there will be a logged-in message in Kibana, including the name of the container and the stack. The final docker-compose.yml will look like this: logspout: image: gliderlabs/logspout:v3 command: 'syslog://logstash:5000' links: - logstash volumes: - '/var/run/docker.sock:/tmp/docker.sock' logstash: image: ludekvesely/logstash-json environment: - DROP_NON_JSON=false - STDOUT=false links: - elasticsearch kibana: image: kibana environment: - LOGSPOUT=ignore links: - elasticsearch ports: - '5601:5601' elasticsearch: image: elasticsearch environment: - LOGSPOUT=ignore In addition to processing a syslog message, it can also process JSON, so it is possible to modify your application to log in JSON format and Logstash automatically processes it.

One such I created is available at Docker Hub. However, this will become a docker-compose.ymlbit unclear, better to create your own image - write the Dockerfile. We will modify the file docker-compose.yml- add the section logspout: logspout: image: gliderlabs/logspout:v3 command: 'udp://logstash:5000' links: - logstash volumes: - '/var/run/docker.sock:/tmp/docker.sock' kibana: image: kibana links: - 'elastic:elasticsearch' ports: - '5601:5601' logstash: image: logstash command: 'logstash -e 'input Logspout has several adapters for output routing: tcp, udp, syslog. Linking a daemon docker and a logspot is just a file access /var/run/docker.sock. Automatically detects new containers, so existing stacks can be used unaltered. This is the prepared image that runs, the socket docker gets a daemon through which he reads the logs of all running containers and moves them forward. Collection of container logs: logspoutДЇor this purpose, the logspout tool ( GitHub, Docker Hub ) was created. There is nothing to change, just another service that logs in and logs to Logstash. Next, I will describe the third option because it will enable logging on independently of the running containers.

This functionality has been added to the Docker in version 1.6, several drivers are currently available, among GitHub issues IвЂ™ve found a logstash driver, probably the best syslog option. This will replace the default logging into a JSON file. The container actively writes logs to that location, in the previous case, the container is passive and the logs are collected. Similar to the previous variants, except that the container at startup tells where to log in. The application logs to standard output, the container has logging-drivers set By default, Docker writes these logs as JSON to the file system, so they have to read these files.Д¤. This is a better option - all logs that containers produce are accessed in a uniform way. The application logs to standard output, logs collect another service Here are the same issues as above, and there is a problem with file sharing if the Docker runs on multiple servers.ДЈ. If you are already logging in to a file, you can choose to make it available as volumes and configure Logstash to use it. The application logs into a file, Logstash reads it as input

Better, in my opinion, all logs are directed to standard output and take care of collecting logs at the Docker level.Дў.

HereвЂ™s how to get other logs, such as a webserver or database. For example, in PHP using the Monologue - you set the address and port and logically cheer.

If you have a custom application in your container, you can program logs into Logstashe. Now, we are facing the question of how to get logs of Logstashe containers. Nc localhost 5000 < fail2ban.log but it just stuck there.If you have come to here, congratulations, you have successfully launched ELK Stack, wrote a message to Logstashe who put it in Elasticsearche and then displayed it in Kibana. I even docker exec -it into the logstash container ran:

Docker syslog logstash
