ZooKeeper Web UI (zk-web) as Docker image

This images contains the latest release of zk-web on a minimal Alpine Linux base image with Java 8.

Configuration options

The following non-mandatory options can be passed to the Docker image:

• HTTP_PORT: The container porton which the zk-web application should run. Default 8080.
• USER: The user name for accessing the frontend
• PASSWORD: The password for accessing the frontend
• ZK_DEFAULT_NODE: The default node address, i.e. 192.168.0.100:2181/

Write access
If you want to have write access to your ZooKeeper nodes, you have to set the USER and PASSWORD environment variables!

Running

The image can be run either via Mesos Marathon, or directly on the Docker host.

Via Marathon

The following sets a ZK_DEFAULT_NODE and starts the zk-web application on a Marathon-defined port:

curl -XPOST 'http://192.168.0.100:8080/v2/apps' -d '{
    "id": "zookeeper-web-ui",
    "env": {
        "ZK_DEFAULT_NODE": "192.168.0.100:2181/"
    },
    "container": {
        "docker": {
            "image": "tobilg/zookeeper-webui",
            "network": "BRIDGE",
            "portMappings": [
                { "containerPort": 8080, "protocol": "tcp" }
            ]
        },
        "type": "DOCKER"
    },
    "cpus": 0.5,
    "mem": 1024,
    "instances": 1
}'

Via command line

The following will expose zk-web on the host port 8080:

docker run -d \
  -p 8080:8080 \
  -e ZK_DEFAULT_NODE=192.168.0.100:2181/ \
  --name zk-web \
  -t tobilg/zookeeper-webui
