I want to have multiple instances of an aerospike-server node so load balance because I hit the server with so many requests I get an error saying 'Error Code 22: Operation not allow at this time'.
I assume that having more aerospike-server nodes that i can lessen the load on one node and therefore complete more operations? I'm jsut not sure where to start with this.
I need these nodes all locally on one host. Any help would be great.
My network knowledge isn't great so forgive me for any
My DockerFile:
FROM aerospike/aerospike-server

docker-compose.yml

aerospike.conf network stanza
network {

# Uncomment the following to set the `access-address` parameter to the

}
heartbeat {

}
You could use a multicast heartbeat configuration and get a small cluster of aerospike nodes running on a single machine.
Here are the steps I used:
1) Get the latest Dockerfile from the aerospike repo
git clone https://github.com/aerospike/aerospike-server.docker.git
2) Modify the heartbeat section and use multicast:
heartbeat {
mode multicast
multicast-group 239.1.99.2
port 9918
interval 150
timeout 10
}
3) Build image and cluster with either docker-compose or custom script.
I used the following custom makecluster.sh bash shell script:
cat makecluster.sh
docker build -t "aerospike/aerospike-server" .
for i in {3..9} ; do
echo $i;
docker stop aerospike${i}
docker rm aerospike${i}
docker run -tid --name aerospike${i} -p ${i}000:3000 -p ${i}001:3001 -p ${i}002:3002 -p ${i}003:3003 aerospike/aerospike-server
done;
and run:
./makecluster.sh

Note: Tools like AMC or asadm , may not be able to see the full cluster if running outside of a docker container on the host machine. In such use case, you may need to try a docker host network and different listening ports in aerospike.conf or the alternative is to run AMC in a container.
6) If using --network=host then you will need to modify the listening ports in aerospike.conf. Each instance running on the same host with same ip address should use a different port when using host network.
Example:
cat makecluster.sh
docker build -t "aerospike/aerospike-server" .
for i in {6..9} ; do
echo $i;
docker stop aerospike${i}
docker rm aerospike${i}
docker run -tid --name aerospike${i} -v /root/docker/aerospike-server.docker/aerospike${i}:/etc/aerospike --network host -p ${i}000:${i}000 -p ${i}001:${i}001 -p ${i}002:${i}002 -p ${i}003:${i}003 aerospike/aerospike-server
