$ sudo docker run -p 8080:8080 –log-driver=json-file gs-rest-service Docker container sending logs to json-fileīreak out of the container started earlier, and start the container again explicitly specifying a json-file logging driver. We have the container’s port 8080 mapped directly to the host, so you can call curl on localhost:8080 exactly like before. $ sudo docker run -p 8080:8080 gs-rest-service $ sudo docker build -t gs-rest-service -f src/main/docker/Dockerfile. If you want to build the Docker image and run gs-rest-service in a docker container where port 8080 is mapped directly to the docker host: If you have not installed Docker, here are instructions for Ubuntu. Now that we have seen our example project deployed directly on our host machine, let’s move on to deploying it into a Docker container. Spring Boot project deployed in Docker container This console level output will be redirected using the appropriate Docker logging driver in the subsequent sections. Then you can make a client call into this service by using curl:Įach call to the service will output debug level logs to the console. $ java -jar target/gs-rest-service-0.1.0.jar
SPRING BOOT DOCKER SYSLOG INSTALL
$ sudo apt-get install curl git openjdk-7-jdk maven -y Later in this article we put this application into a Docker container, but for now let’s run it directly on our Ubuntu host machine. It uses SLF4J/Logback so we configure ‘src/main/resources/logback.xml’ to send events to its ConsoleAppender. Using our Spring Boot example fully described here, we will have it output DEBUG level logs to the console. If you would rather explore an alternate Docker logging architecture, using a dedicated container that senses all other containers and routes their log events, see my article on Docker logspout.
SPRING BOOT DOCKER SYSLOG DRIVERS
The Docker logging drivers capture all the output from a container’s stdout/stderr, and can send a container’s logs directly to most major logging solutions (syslog, Logstash, gelf, fluentd).Īs an added benefit, by making the logging implementation a runtime choice for the container, it provides flexibility to use a simpler implementation during development but a highly-available, scalable logging solution in production.

SPRING BOOT DOCKER SYSLOG HOW TO
But unlike a standard deployment where logging to a local file is where the developer’s responsibility typically ends, with Docker we must think about how to log to a public space outside our ephemeral container space. If you are interested in learning more about building RESTful Web Services and Microservices with Spring Boot and Spring Cloud please have a look at my complete video course: Spring Boot Microservices and Spring Cloud.Building services using Spring Boot gives a development team a jump start on many production concerns, including logging. I hope this short tutorial, was helpful for you. For example, if the root package of my Spring Boot application is com.appsdeveloperblog then the logging.level configuration will look for me as below. Where logger is the root package of your Spring Boot application. To do that, add the following configuration property to an application.properties file. You might also need to enable a specific logging level for your application. To make your application log messages to a file, you will need to configure a couple of new properties in the application.properties file. In this tutorial, you will learn how to configure your Spring Boot application to log messages to a file.
