Hazelcast Jet Management Center Docker Image

Hazelcast Jet Management Center enables you to monitor and manage your cluster members running Hazelcast Jet. In addition to monitoring the overall state of your clusters, you can also analyze and browse your jobs in detail.

You can check Hazelcast Jet Documentation and Hazelcast Jet Management Center Documentation for more information.

Quick Start

You can launch Hazelcast Jet Management Center by simply running the following command. Please check available versions for $HAZELCAST_JET_MANAGEMENT_CENTER_VERSION on Docker Store

docker run -p 8081:8081 hazelcast/hazelcast-jet-management-center:$HAZELCAST_JET_MANAGEMENT_CENTER_VERSION

Now you can reach Hazelcast Jet Management Center from your browser using the URL http://localhost:8081.

If you are running the Docker image in the cloud, you should use a public IP of your machine instead of localhost.

docker ps and docker inspect <container-id> can be used to find host-ip. Once you find out host-ip, you can browse Hazelcast Jet Management Center using the URL: http://host-ip:8081.

Configuration

Hazelcast Jet Management Center uses Hazelcast Jet Client to discover the Hazelcast Jet Cluster. You might need to provide a Hazelcast Jet Client XML Configuration file to be able to discover and connect to the Hazelcast Jet Cluster.

Using Custom Hazelcast Jet Client XML Configuration File

If you need to configure Hazelcast with your own hazelcast-client.xml, you need to mount the folder that has hazelcast-client.xml. You also need to pass the hazelcast-client.xml file path as MC_CLIENT_CONFIG environment variable. Please see the following example:

$ docker run -p 8081:8081 -e MC_CLIENT_CONFIG="/opt/hazelcast/config_ext/hazelcast-client.xml" -v PATH_TO_LOCAL_CONFIG_FOLDER:/opt/hazelcast/config_ext hazelcast/hazelcast-jet-management-center:$HAZELCAST_JET_MANAGEMENT_CENTER_VERSION

License Key Configuration

Hazelcast Jet Management Center free trial is limited to a single node. If you have a bigger cluster you can apply for a trial. To provide a license key to docker container MC_LICENSE_KEY environment variable can be used:

docker run -e MC_LICENSE_KEY=<your-license-key> -p 8081:8081 hazelcast/hazelcast-jet-management-center:$HAZELCAST_JET_MANAGEMENT_CENTER_VERSION

Username and Password Configuration

Basic username and password authentication with a single user can be configured on Hazelcast Jet Management Center to prevent unauthorized parties to achieve unexpected actions on the Hazelcast Jet Cluster.

The username and password can be configured via environment variables like following;

docker run -e MC_USER=username MC_PASSWORD=password -p 8081:8081 hazelcast/hazelcast-jet-management-center:$HAZELCAST_JET_MANAGEMENT_CENTER_VERSION

Using Custom Properties File

Hazelcast Jet Management Center can be configured via a properties file called application.properties.

The ZIP packaging includes an application.properties file that you can override the configuration properties.

The default content of the application.properties file can be seen below;

# path for client configuration file (yaml or xml)
jet.clientConfig=
# License key for management center
jet.licenseKey=

# How many seconds of data to retain for each metric
jet.metrics.retentionSecs=3600

# User Authentication Configuration
spring.security.user.name=admin
spring.security.user.password=admin

# Sever Configuration Options
# server.port: 8081

# SSL configuration options for the web server
# server.ssl.key-store: keystore.p12
# server.ssl.key-store-password: mypassword
# server.ssl.keyStoreType: PKCS12
# server.ssl.keyAlias: tomcat

To pass a custom properties file to the Hazelcast Jet Management Center, MC_APPLICATION_CONFIG environment variable can be used like following:

$ docker run -p 8081:8081 -e MC_APPLICATION_CONFIG="/opt/hazelcast/config_ext/application.properties" -v PATH_TO_LOCAL_PROPERTIES_FOLDER:/opt/hazelcast/config_ext hazelcast/hazelcast-jet-management-center:$HAZELCAST_JET_MANAGEMENT_CENTER_VERSION

Extending CLASSPATH with new jars or files

If you have custom jars or files to put into classpath of docker container, you can simply use CLASSPATH environment variable and pass it via docker run command. Please see the following example:

$ docker run -e CLASSPATH="/opt/hazelcast-jet/CLASSPATH_EXT/" -v PATH_TO_LOCAL_CONFIG_FOLDER:/opt/hazelcast/CLASSPATH_EXT hazelcast/hazelcast-jet-management-center:$HAZELCAST_JET_MANAGEMENT_CENTER_VERSION
