Terraform & Ansible
Automated deployments are done using Terraform to create servers on AWS then Ansible to create and manage testnets on those servers.
Prerequisites
- Install Terraform and Ansible on a Linux machine.
- Create an AWS API token with EC2 create capability.
- Create SSH keys
export AWS_ACCESS_KEY_ID="2345234jk2lh4234"
export AWS_SECRET_ACCESS_KEY="234jhkg234h52kh4g5khg34"
export TESTNET_NAME="remotenet"
export CLUSTER_NAME= "remotenetvalidators"
export SSH_PRIVATE_FILE="$HOME/.ssh/id_rsa"
export SSH_PUBLIC_FILE="$HOME/.ssh/id_rsa.pub"
These will be used by both terraform
and ansible
.
Create a remote network
SERVERS=1 REGION_LIMIT=1 make validators-start
The testnet name is what's going to be used in --chain-id, while the cluster name is the administrative tag in AWS for the servers. The code will create SERVERS amount of servers in each availability zone up to the number of REGION_LIMITs, starting at us-east-2. (us-east-1 is excluded.) The below BaSH script does the same, but sometimes it's more comfortable for input.
./new-testnet.sh "$TESTNET_NAME" "$CLUSTER_NAME" 1 1
Quickly see the /status endpoint
make validators-status
Delete servers
make validators-stop
Logging
You can ship logs to Logz.io, an Elastic stack (Elastic search, Logstash and Kibana) service provider. You can set up your nodes to log there automatically. Create an account and get your API key from the notes on this page, then:
yum install systemd-devel || echo "This will only work on RHEL-based systems."
apt-get install libsystemd-dev || echo "This will only work on Debian-based systems."
go get github.com/mheese/journalbeat
ansible-playbook -i inventory/digital_ocean.py -l remotenet logzio.yml -e LOGZIO_TOKEN=ABCDEFGHIJKLMNOPQRSTUVWXYZ012345
Monitoring
You can install the DataDog agent with:
make datadog-install
