battleware-deployer

Tools for deploying battleware.

Status

battleware-deployer is ALPHA software and is not yet recommended for production use. Developers should expect breaking changes and occasional instability.

Setup

Local

To run this example, you must first install Rust.

Create Artifacts

cargo run --bin battleware-deployer -- generate --peers 5 --bootstrappers 1 --worker-threads 3 --log-level info --message-backlog 16384 --mailbox-size 16384 --deque-size 10 --execution-concurrency 1 --output test --indexer http://127.0.0.1:8080 local --start-port 3000

If setup succeeds, you should see the following output:

Start Validators

Run the emitted start commands in separate terminals:

cargo run --bin validator -- --peers=<your-path>/test/peers.yaml --config=<your-path>/test/10cf8d03daca2332213981adee2a4bfffe4a1782bb5cce036c1d5689c6090997.yaml

It is necessary to start at least one bootstrapper for any other peers to connect (used to exchange IPs to dial, not as a relay).

Debugging

Too Many Open Files

If you see an error like unable to append to journal: Runtime(BlobOpenFailed("engine-consensus", "00000000000000ee", Os { code: 24, kind: Uncategorized, message: "Too many open files" })), you may need to increase the maximum number of open files. You can do this by running:

ulimit -n 65536

MacOS defaults to 256 open files, which is too low for the default settings (where 1 journal file is maintained per recent view).

Remote

To run this example, you must first install Rust and Docker.

Install commonware-deployer

cargo install commonware-deployer

Create Artifacts

cargo run --bin battleware-deployer -- generate --peers 50 --bootstrappers 5 --worker-threads 3 --log-level info --message-backlog 16384 --mailbox-size 16384 --deque-size 10 --execution-concurrency 4 --indexer TODO --output assets remote --regions us-west-1,us-east-1,eu-west-1,ap-northeast-1,eu-north-1,ap-south-1,sa-east-1,eu-central-1,ap-northeast-2,ap-southeast-2 --monitoring-instance-type c7g.4xlarge --monitoring-storage-size 100 --randotron-instance-type c7g.xlarge --randotron-storage-size 25 --instance-type c7g.xlarge --storage-size 25 --dashboard dashboard.json

Build Validator Binary

Build Cross-Platform Compiler

docker build -t battleware-builder .

Compile Binary for ARM64

docker run -it -v ${PWD}/..:/battleware battleware-builder

Local Compilation

Before running this command, ensure you change any version dependencies you'd like to compile locally to path dependencies in Cargo.toml.

docker run -it -v ${PWD}/..:/battleware -v ${PWD}/../../monorepo:/monorepo battleware-builder

Emitted binary battleware-node and battleware-randotron are placed in assets.

Deploy Validator Binary

cd assets
deployer ec2 create --config config.yaml

Monitor Performance on Grafana

Visit http://<monitoring-ip>:3000/d/chain

This dashboard is only accessible from the IP used to deploy the infrastructure.

[Optional] Update Validator Binary

Re-Compile Binary for ARM64

docker run -it -v ${PWD}/..:/battleware battleware-builder

Restart Validator Binary on EC2 Instances

deployer ec2 update --config config.yaml

Destroy Infrastructure

deployer ec2 destroy --config config.yaml

Debugging

Missing AWS Credentials

If commonware-deployer can't detect your AWS credentials, you'll see a "Request has expired." error:

2025-03-05T01:36:47.550105Z  INFO deployer::ec2::create: created EC2 client region="eu-west-1"
2025-03-05T01:36:48.268330Z ERROR deployer: failed to create EC2 deployment error=AwsEc2(Unhandled(Unhandled { source: ErrorMetadata { code: Some("RequestExpired"), message: Some("Request has expired."), extras: Some({"aws_request_id": "006f6b92-4965-470d-8eac-7c9644744bdf"}) }, meta: ErrorMetadata { code: Some("RequestExpired"), message: Some("Request has expired."), extras: Some({"aws_request_id": "006f6b92-4965-470d-8eac-7c9644744bdf"}) } }))

EC2 Throttling

EC2 instances may throttle network traffic if a workload exceeds the allocation for a particular instance type. To check if an instance is throttled, SSH into the instance and run:

ethtool -S ens5 | grep "allowance"

If throttled, you'll see a non-zero value for some "allowance" item:

bw_in_allowance_exceeded: 0
bw_out_allowance_exceeded: 14368
pps_allowance_exceeded: 0
conntrack_allowance_exceeded: 0
linklocal_allowance_exceeded: 0
