This repository contains the Docker build definition and release process for openzipkin/zipkin. It also contains test images for transport and storage backends such as Kafka or Cassandra.
Regarding production usage
The only images OpenZipkin provides for production use are:
- openzipkin/zipkin: The core server image that hosts the Zipkin UI, Api and Collector features.
- openzipkin/zipkin-dependencies: pre-aggregates data such that http://your_host:9411/dependency shows links between services.
If you are using these images and run into problems, please raise an issue or join gitter.
The other images here, and docker-compose, are for development and exploration purposes. For example, they aim to help you integrate an entire zipkin system for testing purposes, without having to understand how everything works, and without having to download gigabytes of files.
openzipkin/zipkin-cassandra was not designed for real usage.
You'll notice it has no configuration available to run more than one node
sensibly, neither does it handle file systems as one would "in real life". We
expect production users to use canonical images for storage or transports like
Kafka, and only those testing or learning zipkin to use the ones we have here.
Zipkin has no dependencies, for example you can run an in-memory zipkin server like so:
docker run -d -p 9411:9411 openzipkin/zipkin
See the ui at (docker ip):9411
In the ui - click zipkin-server, then click "Find Traces".
Configuration is via environment variables, defined by zipkin-server. Notably, you'll want to look at the
STORAGE_TYPE environment variables, which
include "cassandra", "mysql" and "elasticsearch".
When in docker, the following environment variables also apply
JAVA_OPTS: Use to set java arguments, such as heap size or trust store location.
STORAGE_PORT_9042_TCP_ADDR-- A Cassandra node listening on port 9042. This environment variable is typically set by linking a container running
zipkin-cassandraas "storage" when you start the container.
STORAGE_PORT_3306_TCP_ADDR-- A MySQL node listening on port 3306. This environment variable is typically set by linking a container running
zipkin-mysqlas "storage" when you start the container.
STORAGE_PORT_9200_TCP_ADDR-- An Elasticsearch node listening on port 9200. This environment variable is typically set by linking a container running
zipkin-elasticsearchas "storage" when you start the container. This is ignored when
KAFKA_PORT_2181_TCP_ADDR-- A zookeeper node listening on port 2181. This environment variable is typically set by linking a container running
zipkin-kafkaas "kafka" when you start the container.
This project is configured to run docker containers using docker-compose. Note that the default configuration requires docker-compose 1.6.0+ and docker-engine 1.10.0+. If you are running older versions, see the Legacy section below.
To start the default docker-compose configuration, run:
$ docker-compose up
View the web UI at $(docker ip):9411.
To see specific traces in the UI, select "zipkin-server" in the dropdown and then click the "Find Traces" button.
The default docker-compose configuration defined in
backed by MySQL. This configuration starts
zipkin-dependencies (cron job) in their own containers.
The docker-compose configuration can be extended to use Cassandra instead of
MySQL, using the
docker-compose-cassandra.yml file. That file employs
to swap out one storage container for another.
To start the Cassandra-backed configuration, run:
$ docker-compose -f docker-compose.yml -f docker-compose-cassandra.yml up
The docker-compose configuration can be extended to use Elasticsearch instead of
MySQL, using the
docker-compose-elasticsearch.yml file. That file employs
to swap out one storage container for another.
To start the Elasticsearch-backed configuration, run:
$ docker-compose -f docker-compose.yml -f docker-compose-elasticsearch.yml up
Elasticsearch 5 and Host setup
docker-elasticsearch5 image is more strict about virtual memory. You will need to adjust accordingly (especially if you notice elasticsearch crash!)
# If docker is running on your host machine, adjust the kernel setting directly $ sudo sysctl -w vm.max_map_count=262144 # If using docker-machine/Docker Toolbox/Boot2Docker, remotely adjust the same $ docker-machine ssh default "sudo sysctl -w vm.max_map_count=262144"
Elasticsearch Service on Amazon
If you are using Elasticsearch against Amazon, it will search for credentials including those
~/.aws directory. If you want to try Zipkin against Amazon Elasticsearch Service, the
easiest start is to share your credentials with Zipkin's docker image.
For example, if you are able to run
aws es list-domain-names, then you
should be able to start Zipkin as simply as this:
$ docker run -d -p 9411:9411 \ -e STORAGE_TYPE=elasticsearch -e ES_AWS_DOMAIN=your_domain \ -v $HOME/.aws:/root/.aws:ro \ openzipkin/zipkin
The docker-compose configuration can be extended to host a test Kafka broker
docker-compose-kafka.yml file. That file employs
to add a Kafka+ZooKeeper container and relevant settings.
To start the MySQL+Kafka configuration, run:
$ docker-compose -f docker-compose.yml -f docker-compose-kafka.yml up
By default, this assumes your Docker host IP is 192.168.99.100, which is what you would use for the broker IP when configuring application instrumentation.
The docker-compose configuration can be extended to host the experimental new
UI on port 80 using
That file employs docker-compose overrides
to add an NGINX container and relevant settings.
To start the NGINX configuration, run:
$ docker-compose -f docker-compose.yml -f docker-compose-ui.yml up
This container doubles as a skeleton for creating proxy configuration around Zipkin like authentication, dealing with CORS with zipkin-js apps, or terminating SSL.
The docker-compose files described above use version 2 of the docker-compose
config file format. There is a legacy version 1 configuration also available, in
docker-compose-legacy.yml. That configuration relies on container linking.
To start the legacy configuration, run:
$ docker-compose -f docker-compose-legacy.yml up
All images share a base image,
openzipkin/jre-full, built on the Alpine image
delitescere/java:8, which is much
smaller than the previously used
If using a provided MySQL server or image, ensure schema and other parameters match the docs.
