Hazelcast Docker Compose - padogrid/padogrid GitHub Wiki
This page describes how to create a Docker environment and launch a Hazelcast cluster using docker-compose
.
❗ You must first install Docker and Docker Compose. See References for download links.
# Create Hazelcast cluster with 2 members (default)
create_docker -cluster mydocker
By default, the create_docker command adds two (2) Hazelcast servers (members) in the cluster. You can change the number of servers using the -count
option. For example, the following command adds four (4) servers.
# Create Hazelcast cluster with 4 members
create_docker -cluster mydocker -count 4
cd_docker mydocker
Edit the .env
file as needed.
vi .env
There are three (3) Hazelcast configuration files as follows. Edit them as needed.
Configuration File | Cluster Type |
---|---|
padogrid/etc/hazelcast.xml |
IMDG, Jet |
padogrid/etc/hazelcast-jet.xml |
Jet |
padogrid/etc/hazelcast-client.xml |
Jet |
❗By default, the cluster name is hard-coded in the padogrid/etc/hazelcast.xml
file as dev
, even though the Docker cluster name is mydocker
in our example. If you want to keep the Hazelcast cluster name same as the Docker cluster name then uncomment the padogrid.cluster-name
system property in the padogrid/etc/hazelcast.xml
file.
❗ For Jet Management Center, the cluster member addresses are listed in the padogrid/etc/hazelcast-client.xml
file using the HOSTNAME_FOR_CLIENTS
value set in the .env
file. If you change the value of HOSTNAME_FOR_CLIENTS
then you must also make the same change in the padogrid/etc/hazelcast-client.xml
file.
vi padogrid/hazelcast.xml
Place your application jar files in the padogrid/plugins
directory, which already contains PadoGrid test jar for running perf_test
.
ls padogrid/plugins
docker-compose up
Management Center URLs are as follows:
URL | Cluster Type |
---|---|
http://localhost:8080/hazelcast-mancenter | IMDG |
http://localhost:8081 | Jet |
❗ If you have not changed the Hazelcast cluster name, then keep in mind that the Hazelcast cluster name is set to dev
by default as mentioned earlier. When you add a cluster config in Hazelcast Management Center 4.x, you must set the member addresses with the host IP address, and not localhost
.
If you have not changed the Hazelcast cluster name, you can run perf_test
as is without modifications.
create_app
cd_app perf_test; cd bin_sh
./test_ingestion -run
If you have changed the Hazelcast cluster name, then add the <cluster-name>
element in the etc/hazelcast-client.xml
file as follows:
<hazelcast...>
...
<cluster-name>mydocker</cluster-name>
...
</hazelcast>
Ctrl-C from the docker-compose up
command and prune the containers.
docker-compose down
docker container prune
