ecs-embedded's Issues
https://guides.hazelcast.org/ecs-embedded/ hazelcast-aws dependency issue?
Hi, I'm trying to follow this guide: https://guides.hazelcast.org/ecs-embedded/
Our environment is slightly different so I'm taking a few steps differently, but nonetheless following the guide, and the documentation: https://github.com/hazelcast/hazelcast-aws
The guide has a number of steps:
Create an Application
Use Hazelcast AWS ECS Configuration
Containerize the Application
These three I skip by following this part of the guide:
"If you want to use your image in the following steps, please also make sure your Docker Hub registry is public. However, for the purpose of this guide, you can also use the already built hazelcastguides/hazelcast-embedded-ecs Docker image."
I have a Dockerfile (I tried both yaml and xml configurations, hence copying both. I also tried starting from the embedded ecs image - hazelcastguides/hazelcast-embedded-ecs):
from hazelcast/hazelcast:4.0.3
COPY hazelcast.xml /configFolder/hazelcast.xml
COPY hazelcast.yaml /configFolder/hazelcast.yaml
For example, my hazelcast.yaml looks like so:
hazelcast:
network:
join:
multicast:
enabled: false
aws:
enabled: true
interfaces:
enabled: true
interfaces:
- 10.0.*.*
I build and deploy this image to my ECR repo, which my task definition pulls from to create the service:
def build_docker(image, repository=image, directory=image){
AWS_ECR_REPO="<MY-AWS-ACCOUNT-ID>.dkr.ecr.us-east-2.amazonaws.com"
AWS_REGION="us-east-2"
sh "docker build -t ${image} ./${directory}"
TAGID=sh(returnStdout: true, script: "docker images -q ${image} | head -n1 | tr -d ' \t\n\r'")
echo "TAGID: ${TAGID}"
sh """
docker tag ${TAGID} ${AWS_ECR_REPO}/${repository}
aws ecr get-login-password --region ${AWS_REGION} | docker login --username AWS --password-stdin ${AWS_ECR_REPO}
docker push ${AWS_ECR_REPO}/${repository}
"""
}
build_docker("hazelcast", "hazelcast", "config")
Once it's in ECR, my task definition picks it up (I don't follow the guides task-definition, because our hazelcast relies on kafka, and zookeeper to run):

I'm running on EC2 instances, but my docker containers are running by awsvpc mode so I won't be using the host mode (more than one container per instance)
Getting back to the guide again. My Cluster is 2 EC2 instances, inside my VPC. Since all hazelcast traffic will operate within the private network, my security group covers this and I'm not using the guide's SG. Here are my SG rules:
INBOUND
Type | Protocol | Port range | Source | Description - optional
-- | -- | -- | -- | --
HTTP | TCP | 80 | 0.0.0.0/0 | –
All traffic | All | All | 10.0.0.0/8 | –
HTTPS | TCP | 443 | 0.0.0.0/0 | –
All ICMP - IPv4 | ICMP | All | 0.0.0.0/0 | –
OUTBOUND
Type | Protocol | Port range | Destination | Description - optional
-- | -- | -- | -- | --
All traffic | All | All | 0.0.0.0/0 | –
All ICMP - IPv4 | ICMP | All | 0.0.0.0/0 | –
For the section of the Guide: Create IAM Role. I followed this exactly, and you can see the roles defined as in my task-definition.json.
AWS Cloud watch logs are forwarding appropriately.
To create the service I run
aws ecs create-service --cli-input-json file://prod-service-definition.json
that file looks like this:
{
"cluster": "prod",
"serviceName": "example-all",
"taskDefinition": "example-all",
"desiredCount": 2,
"clientToken": "",
"launchType": "EC2",
"deploymentConfiguration": {
"maximumPercent": 200,
"minimumHealthyPercent": 40
},
"networkConfiguration": {
"awsvpcConfiguration": {
"subnets": [
"subnet-0a9a855f0fb73149f",
"subnet-05a4a4fef6ac10156",
"subnet-08f8f9c098e5f790c"
],
"securityGroups": [
"sg-010eaa7278a139b82"
],
"assignPublicIp": "DISABLED"
}
},
"healthCheckGracePeriodSeconds": 0,
"schedulingStrategy": "REPLICA",
"deploymentController": {
"type": "ECS"
},
"enableECSManagedTags": true,
"propagateTags": "SERVICE"
}
Again, these containers won't need public IPs, they're sitting in the private subnet and using awsvpc networking.
That's about it for steps to reproduce. Now as for the exception I'm getting. It's a null pointer, so it doesn't really help me identify what I need to fix next. This is what I see on cloudwatch:

Policy file contents are missing on the guide
In Create IAM Role section, file://policy.json and file://role-policy.json files are passed to CLI commands but the content of these are missing or even they exist they're not visible/clear to where to look for them.
Whoops I was looking for the other Spring repo referred in the guide.
ECS guide only covers embedded mode
ECS guide should be written with client/server mode first, and embedded should be an optional step.
