COMET Docker image

Pull image from dockerhub

docker pull rencinrig/comet-spring:latest

Or Build docker image locally

Dockerfile is in the same directory as pom.xml:

comet-accumulo/
    Dockerfile
    pom.xml

Follwing command will build the docker image:

cd comet-accumulo/
mvn clean package dockerfile:build

RUN in Docker Compose

Run together with zookeeper and RENCI accumulo docker images to form the cluster

The docker-compose.yml and the site-files to start the Accumulo cluster instances are under folder docker-compose.

Start Comet after Zookeepers and Accumulo are ready:

cd docker-compose/
docker-compose run start-zoo
docker-compose run start-accumulo
docker-compose up comet

Stop and Romove the containers

docker-compose stop
codker-compose rm -f

To run the COMET standalone

docker run -it --rm \
  --name comet \
  -p 8111:8111 \
  -v $(pwd)/log:/var/log \
  --env-file <env file> \
  rencinrig/comet-spring

or in detached mode:

docker run -it -d \
  --name comet \
  -p 8111:8111 \
  -v $(pwd)/log:/var/log \
  --env-file <env file> \
  rencinrig/comet-spring

Environment Variables

Some properties of COMET can be configured through following environment variables.

COMET_CHECK_TOKEN_STRENGTH

Turn on/off token strength checking. Default is false.

COMET_CHECK_CLIENT_CERT

Turn on/off client certificate checking. Default is true.

ACCUMULO_INSTANCE

Accumulo Server name. Default is aws-development. Change this to your Accumulo's instance name such as docker-developement.

ACCUMULO_ZOOSERVERS

Zookeeper server names. Default is zoo1,zoo2,zoo3.

ACCUMULO_USER

Accumulo user name. Default is root.

ACCUMULO_PASSWORD

Accumulo password. Default is secret.

ACCUMULO_TABLENAME

Accumulo table name. Default is trace.

COMET_RETRY_DURATION

In milliseconds.
Default is 1000 (1s).
For some accumulo operations such as read and enumerate, COMET will retry for this duration of time.

COMET_RECORD_EXPIRE_TIME

In milliseconds.
Records are expected to access (i.e. Read/Enumerate/Write) at least once in this period of time in order to keep records alive. Otherwise records might be deleted by Accumulo ageoff feature.

Default value is 0, which means Comet won't do anything to guarantee TTL.
If Accumulo has AgeOffFilter set up already, records might be lost.

Example

COMET_CHECK_TOKEN_STRENGTH=false
COMET_CHECK_CLIENT_CERT=false
ACCUMULO_INSTANCE=docker-development
ACCUMULO_ZOOSERVERS=zoo1,zoo2,zoo3
ACCUMULO_USER=user
ACCUMULO_PASSWORD=password
ACCUMULO_TABLENAME=trace

Log file

Log file is stored in /var/log/comet.log on the container To see the log, mount your desired log folder to /var/log on the container.
