Quickstart for localhost development

Install docker: https://docs.docker.com/engine/installation/

Following steps will bring up the docker container running cadence server along with all its dependencies (cassandra, statsd, graphite). Exposes cadence frontend on port 7933 and grafana metrics frontend on port 8080.

cd $GOPATH/src/github.com/uber/cadence/docker
docker-compose up

View metrics at localhost:8080/dashboard

Using a pre-built image

With every tagged release of the cadence server, there is also a corresponding docker image that's uploaded to docker hub. In addition, the release will also contain a docker.tar.gz file (docker-compose startup scripts). Go here to download a latest docker.tar.gz

Execute the following commands to start a pre-built image along with all dependencies (cassandra/statsd).

tar -xzvf docker.tar.gz
cd docker
docker-compose up

Building an image for any branch and restarting

Replace YOUR_TAG and YOUR_CHECKOUT_BRANCH in the below command to build:

cd $GOPATH/src/github.com/uber/cadence/docker
docker build . -t ubercadence/server:YOUR_TAG --build-arg git_branch=YOUR_CHECKOUT_BRANCH

Replace the tag of image: ubercadence/server to YOUR_TAG in docker-compose.yml . Then stop service and remove all containers using the below commands.

docker-compose down
docker-compose up

Quickstart for production

In a typical production setting, dependencies (cassandra / statsd server) are managed / started independently of the cadence-server. To use the container in a production setting, use the following command:

docker run -e CASSANDRA_CONSISTENCY=Quorum \            -- Default cassandra consistency level
    -e CASSANDRA_SEEDS=10.x.x.x                         -- csv of cassandra server ipaddrs
    -e KEYSPACE=<keyspace>                              -- Cassandra keyspace
    -e VISIBILITY_KEYSPACE=<visibility_keyspace>        -- Cassandra visibility keyspace
    -e SKIP_SCHEMA_SETUP=true                           -- do not setup cassandra schema during startup
    -e RINGPOP_SEEDS=10.x.x.x,10.x.x.x  \               -- csv of ipaddrs for gossip bootstrap
    -e STATSD_ENDPOINT=10.x.x.x:8125                    -- statsd server endpoint
    -e NUM_HISTORY_SHARDS=1024  \                       -- Number of history shards
    -e SERVICES=history,matching \                      -- Spinup only the provided services
    -e LOG_LEVEL=debug,info \                           -- Logging level
    ubercadence/server:<tag>

Update docker-compose.yml when releasing new version

  1. Creat new version tag in the repo
  2. Build the new docker image and push into docker hub
docker build . -t ubercadence/server:THE.LATEST.VERSION  --build-arg git_branch=vTHE.LATEST.VERSION 
docker push ubercadence/server:master
  1. Remember to update the docker-compose.yml to use latest version and check in to master
  cadence:
    image: ubercadence/server:THE.LATEST.VERSION 
    ports
  1. Create the tar.gz file and upload to relase page
cd github.com/uber/cadence/docker
tar -cvf docker.tar.gz *
